Dark Energy and Creation

Dark Energy and Creation
One of the great mysteries of cosmology is the fact that the cosmos is speeding up as it expands. Scientists explain this acceleration by an invisible pressure called dark energy which makes up about 70% of the energy in the cosmos.

This explanation is based on an assumption called the Friedmann-Lemaitre-Robertson-Walker metric which took Einstein’s equations and applied them to a universe they assumed to be homogeneous and isotropic. In other words, it assumes a smooth universe. Science has determined that the universe is not smooth. It is made up of great voids separating networks of dense galaxy clusters and filaments.

Emily Conover writing in Science News for November 25, 2017, (page 22) said, “If the universe were soup, it would be more of a chunky minestrone than a silky smooth tomato bisque.” When the equations are applied to a universe that is not isotropic and homogeneous, the acceleration of the cosmos seems to be explained without the need for dark energy. By the very nature of the lumpy design of the cosmos, its collapse is avoided.

It is interesting to note that the cosmos was created in such a way that its very existence contains the fingerprint of a design that allows great stability over an infinite amount of time. The more we know of the creation, the closer we get to the Creator.

Many aspects of the creation we may never understand, but as our instruments get better and data accumulates, we understand that we have, in the words of Issac Newton, “found a pebble of knowledge while an ocean of truth lays before us.”

“In the beginning God created the heavens and the earth” is really all we need to know. Seeing His power, wisdom and design bolsters our faith in the fact that “The Lord possessed wisdom at the beginning of his work, before his deeds of old: wisdom was appointed from eternity from the beginning. Before the world began…” Proverbs 8:22-23.

Kepler-90: Our Twin Solar System?

Is Kepler-90 a Twin to Our Solar System?
It seems that every week astronomers make an announcement that the media use to suggest that the cosmos is overflowing with life similar to planet Earth. The latest system presented as identical to our solar system–and therefore harboring life–is around a star known as Kepler-90, 2545 light-years away.

Kepler-90 is made up of a parent star and eight planets, the same as ours. The star that serves as the sun for the Kepler system is a G type star, and our Sun is a G-2 star. Some of Kepler-90’s planets are rocky planets comparable to the Earth. There are also two large planets comparable to Jupiter and Saturn. Three of Kepler-90’s planets are the size of Uranus and Neptune. Tabloids have been calling this system our twin because of these similarities. They are even suggesting that we need to make contact with the “humanoids” living there.

The reality is that no scientist, at least in print, feels that this solar system is the same as ours. First, all of Kepler-90’s planets are closer to the sun of the system than the Earth is to our Sun. They would undoubtedly be much too hot to support any kind of life based on carbon, oxygen, and hydrogen. It is also important to note that in our solar system our large planets have a function that can only happen if they are farther from the Sun than the life-bearing planet. Jupiter, Saturn, Uranus, and Neptune all serve as shields to planet Earth. The four Jovian planets will absorb any large object from outside the solar system that is on a collision course with Earth. The famous Shoemaker-Levy 9 comet in 1992 was torn apart by Jupiter and destroyed. Had Jupiter not shielded the Earth, the collision of the Earth and Shoemaker-Levy 9 would have been devastating.

A system with a star emitting the right spectra and having rocky planets does not necessarily support the existence of life. We produced a chart titled “Evidence for Design in the Universe” that lists 47 variables necessary for a planet to harbor life. You can access the chart on our doesgodexist.org website, or request it from us and we will mail you a copy.

Astronomers haven’t yet found anything close to a twin to our planet. Even if they did, and even if there were life on it, all that would prove is that God created life elsewhere. It would indicate that the Creator carefully chose the right constants and chemical constituents to allow life to exist.

Messaging Extraterrestrial Intelligence (METI)

Messaging Extraterrestrial Intelligence
Since 1960, scientists have been using radio telescopes to search for signs of intelligent life in the universe. The program is called SETI (Search for Extraterrestrial Intelligence). So far it has been 57 years of listening without any positive results. Scientists have now entered the next phase of the search called Messaging Extraterrestrial Intelligence (METI).

On October 16-18, 2017, scientists beamed a message toward a red dwarf star known as GJ 273 in the hope that there might be someone there listening. Of course, there are always radio and TV signals of various kinds going out from transmitters all over the Earth, but this attempt is a concentrated signal beamed toward this specific system. The transmission contained mathematical and scientific information as well as music. The reason scientists chose GJ 273 is that there are two planets orbiting the star that they hope might be able to support life. And it is the closest possible potential life-supporting location.

Picking one random star to direct a communication signal toward may seem like shooting in the dark–and it is. However, a METI team member said that this is just a prototype of what they want to do “one hundred times, or one thousand times, or one million times.” In other words, this is just the beginning.

So when will the results of this experiment be in? GJ 273 is more than twelve light-years from Earth. So in about 2030, the signal will reach its destination. If there is intelligent life there listening and they respond right away, we might hear something by 2042 or 2043. Translation will be a challenge. If Messaging Extraterrestrial Intelligence continues to send out signals to other potential inhabitable planets, they will be farther away, and thus it will take longer to hear anything back.

Some scientists, such as Stephen Hawking, have criticized this effort because they are afraid it might wake up hostile extraterrestrial beings to the fact that we are here. Perhaps the aliens will not like our music style and decide that they want to put an end to it. They could send their “storm troopers” to start a Star Wars type of scenario. Of course, since they would not be able to travel at anything close to the speed of light (if Einstein is correct), they might arrive here centuries from now to find nobody left on this planet.

We have three observations on this project. First, all indications are that the chances of life existing anywhere in space are very slim. There are far too many variables needed to make life possible on any planet or moon. Secondly, the resources going into SETI and METI could better be used helping people right here on our own planet. Thirdly, as we have said before, whether or not life exists anywhere else in the universe has no bearing on whether God exists. God can create life anywhere He chooses.

When it comes to messaging extraterrestrial intelligence, we believe that there is Intelligence out there. We also believe that He would like to hear from us. We further believe that He has been to Earth to communicate with us. And we believe that if we choose to communicate with Him, we will not be limited to the speed of light. He can hear us instantaneously.

Continental Drift and Recycling

Continental Drift
In 1910 an Arctic explorer by the name of Alfred Wegener coined the term continental drift. Wegener saw the same fossils in South America that he had seen in western Africa, and he proposed that the two continents had been connected at one time. Wegener’s proposal was ridiculed by the scientists of that day who saw the Earth’s crust as too solid to allow any model of that kind to work.

Over the years studies of earthquake epicenters have shown that there is movement of huge slabs of rock called tectonic plates. The rock material bends more and more steeply until the slabs eventually melt into the mantle–the molten interior of the earth. These slabs and everything on them do in fact move.

In 1952 an ocean cartographer by the name of Marie Tharp began making profiles of the Atlantic Ocean floor going from west to east. Her profiles showed a ridge down the center of the Atlantic with younger material in the center and older material on both sides. She proposed that molten material was coming up from the mantle and pushing the two slabs of ocean floor material away from each other. Where the slabs hit the edges of the continent, the material is deflected downward making trenches in the floor of the ocean.

All of these discoveries flew in the face of the accepted geological theory at the time, and Tharp was ridiculed. In time scientists came to understand that the Earth is made up of plates sliding along the surface and sliding down into the mantle when a continent is reached.

There is a message in all of this that what is considered to be scientifically impossible, sometimes turns out to be true. At the same time, a pet theory can ultimately be proven incorrect. One of the beauties of science is that eventually it cleans up its own mistakes.

Another message is that sometimes God addresses a problem long before humans know there is a problem. This whole process is one of the greatest recycling systems of all time. As nutrients and minerals get eroded off the continents, they are deposited on the ocean floor. The movement of the ocean floor ultimately returns this material to the mantle to be recycled back to the Earth’s surface.

No elements are lost from the Earth’s reservoir by this system, and it assures us that there is no waste in the resources of the planet as a whole. Jeremiah 10:12 speaks of God preserving the Earth by His wisdom, and continental drift is one of tools by which He does that.

Life on Other Planets Doubtful

Life on Other Planets?
We have repeatedly pointed out that finding life on other planets has no bearing on the question of God’s creation of life on Earth. The Bible does not say that this is the only place where God created life.

Astronomers have observed over 3500 planets orbiting stars other than our Sun. Many writers have suggested that life in space is natural and likely because of the number of planets that exist. That assumption has a problem. There are an enormous number of variables that must be precisely controlled to allow life to exist.

Scientists have recently discovered that while it takes 243 days for Venus to rotate once, its atmosphere requires only four days in what is called “superrotation.” How can a planet’s atmosphere rotate 60 times faster than the planet itself? What effect does this have on the conditions at the surface of the planet where life could exist?

Another recent discovery concerns Proxima Centauri b, a planet orbiting in the habitable zone of the closest star to us other than the Sun. The star it orbits, Proxima Centauri, is continuously flaring and driving away any atmosphere that an orbiting planet might have. Astronomers working on the study of this star and the planets around it released a statement saying “any chance for life on Proxima Centauri b may be toast.”

We continue to find that the conditions needed for life on other planets are numerous. Having water is important, but many other factors must be carefully controlled for a planet to support even the most simple forms of life.

God’s creation of the Earth and the conditions that allow life to exist here becomes more and more amazing as we learn more about the cosmos.

Stretched Out Gravity Waves and the Nobel Prize

Stretched Out Gravity Waves
One of the interesting words in the Old Testament dealing with space and its creation is the Hebrew word natah–usually translated stretched out.

This word describes God’s act of creating space/time. Natah suggests that the cosmos is a like fabric that can be stretched. It could also mean stretching out as when we pull the cord of a lawnmower or outboard motor. (For uses of the word natah, see: Psalms 104:2; Isaiah 40:22; 44:24; 45:12; 51:13; Jeremiah 51:15; Zechariah 12:1)

Three United States scientists won the Nobel physics prize in October of 2017 by detecting ripples of gravitational waves traveling through the universe. In September of 2015, these scientists and others detected gravitational waves for the first time confirming a part of Einstein’s predictions.

The bottom line is that space is not empty, and objects in space are not isolated. The creation is like a garment that can have ripples in it. Stretched out gravitational waves fill the universe.

The next step for scientists will be to learn how to use gravity waves to study cosmic phenomena that they can’t observe by light or other electromagnetic radiation. Gravity waves will help us to learn more about God’s creation, and they are another verification of the biblical description of the nature of the cosmos.

NASA’s Creation Account

NASAs Creation Account
Each day NASA posts an interesting astronomy picture of the day at www.apod.nasa.gov. The picture for October 24, 2017, shows the periodic table of the elements. NASA captioned the picture with a summary of the current scientific theories about the formation of the elements of the periodic chart were formed. We call it NASA’s creation account.

It may be that some will want to simply say God did it by “speaking it into existence.” Of course, NASA does not mention God, but their summary does not in any way denigrate God or the way He works. This brief summary demonstrates the majesty and power required to form the creation. The fact that the process has no scientific explanation of an ultimate cause lends support to the statement, “The heavens declare the glory of God and the cosmos declares the work of His hands. Day after day they pour forth speech: night after night they display knowledge” (Psalms 19:1-2).

Here is the summary which you can read on NASA’s website:

“The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.”

We don’t see a conflict between NASA’s creation account and the one found in Genesis 1. The more we learn about the creation, the more we can say, “So that’s how God did it.”

Martian Global Aurora

Martian Global Aurora
On October 6 NASA’s daily space news website apod.nasa.gov contained pictures of a Martian global aurora. Because Mars has virtually no magnetic field, the radiation level goes sky high during solar storms. In the latest storm, radiation levels doubled–which would have been dangerous to life on Mars.

Earth’s magnetic field is very strong, and deflects radiation coming from the Sun. The radiation is deflected toward the poles, which is why we see the auroras near the poles. By deflecting the radiation, the magnetic field protects life on the Earth from dangerous levels. The more we learn about the cosmos, the more we see factors that make life possible on Earth. Our magnetic field is one more example of the design of our planet.

Looking for life in space is not just about whether there is water on a planet. There are a huge number of other factors that must be present. A strong magnetic field to shield from radiation is just one of those factors. Of course, an atmosphere suitable for life is also a requirement. NASA has a space probe called MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiting Mars. The purpose is to find out if Mars lost its atmosphere due to not having a strong magnetic field.

The Martian global aurora is just one more reminder of the blessing of life on planet Earth. It also indicates that life on this planet is no accident.

Titan Studies Verify Earth’s Uniqueness

Titan Studies Verify Earth's Uniqueness
Yesterday we wrote about the end of the Cassini mission. We mentioned that an early highlight of that mission was landing the Huygens probe on Titan in January of 2005. Titan is a moon of Saturn and the largest moon in our solar system. Scientists were very interested in studying Titan thinking they might find evidence of life. Instead, the Titan studies verify Earth’s uniqueness.

It took seven years for the Huygens lander to make the 2.2-billion-mile (3.5 billion km) journey to Saturn on board the Cassini spacecraft. Cassini arrived at Saturn in June 2004, but it was not until Christmas Day that the Titan probe separated from the Cassini spaceship. On January 14, the probe entered the upper atmosphere of Titan at 12,400 miles (almost 20,000 km) per hour. After opening three parachutes, Huygens eventually completed a 150-minute descent to land on the surface of Titan.

As Huygens descended to the surface, it made measurements of all kinds and turned on a spotlight to photograph its soft landing. It then sent pictures and data from the surface of Titan to the Cassini spacecraft for about an hour-and-a-half. The Cassini spacecraft relayed the data and pictures to Earth. This expedition was an incredible success and told us much about conditions in another area of the solar system.

Some experts predicted that they would find life, or at least the precursors of life, on Titan. Spectrographic analysis of the atmosphere had shown a huge amount of nitrogen and some methane (natural gas) in the atmosphere. The presence of methane was of special interest to scientists because methane, with a carbon atom and four hydrogen atoms, is the building block of more complicated organic molecules. Some biochemists predicted massive numbers of complex organic molecules in oceans of hydrocarbons on Titan–perhaps even some basic life-forms.

As the Huygens probe sent back pictures from Titan, scientists were amazed to see carved river channels, old shorelines, and clouds. With a temperature of minus 300 degrees Fahrenheit (-184 C) these obviously could not be water-carved channels. As Huygens landed, it broke through a crusty surface and sank several inches into the ground. The chemical studies of the spongy surface showed that it was not rock, but frozen gaseous material. Titan’s atmosphere could not sustain life. The clouds turned out to be methane, and scientists could find no oxygen or oxygen compounds on Titan. Titan has a spongy surface saturated with organic compounds. The density of Titan tells us that deep down under all of this organic ice there must be very dense rock.

It is becoming apparent that the other planets in our solar system have very little in common with Earth. Titan studies verify Earth’s uniqueness once again. Jonathon Lunine, a planetary scientist who worked on this project, described the findings in this way, “This is a planetary scene like no other, vaguely disturbing and nightmarish to me and certainly not Mars or Venus.”

Our point is that all the discoveries science has made about the solar system have shown how special and unique the Earth is. It is wonderful that humans can build a machine to probe such strange and exotic places. As we learn more about the universe, we see the truthfulness of the Psalmist’s words, “The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge” (Psalms 19:1-2, NIV).

Cassini Exceeded Expectations

Saturn with its rings and some of its moons.Cassini Exceeded Expectations

On the morning of September 15, 2017, Cassini ended its life in fiery destruction. Cassini was a space probe orbiting and studying Saturn, and by all measures, Cassini exceeded expectations.

NASA, the European Space Agency, and the Italian Space Agency worked together on the Cassini-Huygens space exploration project. The mission was to study Saturn along with its moons and rings. NASA launched the spacecraft in 1997, and it arrived near Saturn and went into orbit around that planet in 2004.

The Huygens (pronounced hoy-guns) lander module, provided by the ESA, separated from the Cassini probe and landed on Saturn’s largest moon, Titan, in 2005. The parachute landing was successful, and the probe sent out data for about 90 minutes. In that brief time, scientists learned much about the surface of that distant moon. Viewed from Titan’s surface, the Sun appeared about the size and brightness of a car headlight 150 meters away. The Huygens probe took pictures and told us that Titan’s surface is dotted with rivers, lakes, and oceans made of methane and ethane. It also has dunes up to 300 feet (91 meters) tall.

Meanwhile, the Cassini probe continued to orbit Saturn and send back amazing and beautiful pictures of its rings and moons for 13 years. Cassini helped us to learn more about the moons of Saturn. The planet has at least 53 moons and possibly eight more. We learned that the moon Enceladus is covered with a liquid water ocean with a surface layer of ice 19 to 25 miles (30 to 40 km) thick. Geysers of water erupt from cracks in the ice. The rings of Saturn are a constantly changing collection of ice particles and small rocks. Saturn has hurricane-like storms at both poles and a hexagon-shaped jet stream at the north pole. How long is a day on Saturn? That’s hard to determine because it is a gas planet and not all parts of it move at the same speed. Scientists estimate a little more than 10 hours.

Cassini exceeded expectations by surviving seven years of travel to Saturn plus 13 years orbiting the planet. As it ran out of fuel, scientists sent it hurtling into Saturn’s atmosphere to burn up so it could not contaminate any of Saturn’s moons by crashing into them.

We are fascinated by the Cassini photos and scientists will continue to study them for years. The picture we posted shows a Cassini view of Saturn and its rings with a bright spot visible below the rings. That spot is the planet where we live. As we look at the hostile environment of space and the other planets, we realize how incredible Earth is. God has given us a place with everything we need for life. You might say that compared to any other place in the universe, Earth exceeds expectations.
