X-Ray Vision and X-Ray Destruction

X-Ray Vision and X-Ray Destruction

The fictional character Superman is supposed to have x-ray vision. That super-ability to see through objects is shown in the comics and movies as something coming out from his eyes. As everyone knows, vision doesn’t come out from our eyes. We see because of the light coming into our eyes.

X-rays are electromagnetic radiation similar to visible light, but at a higher energy level and shorter wavelength. Then why can’t we see x-rays? For one thing, our eyes use a lens to focus light on the retina. X-rays can’t be focused by the lens in our eyes, or even by glass lenses. X-rays are focused by using metal tubes to guide the rays because metal is one thing X-rays can’t penetrate.

However, x-rays can penetrate flesh and destroy the molecules by tearing them apart. Even if the lenses of our eyes could focus x-rays on the retina, the x-rays would destroy the retina. Medical and dental x-rays use low doses for short durations, so they don’t pose a health risk. Your body can easily repair the slight damage that occurs.

Another reason we can’t see x-rays is that we are not normally exposed to them, and that’s good news. On Earth, radioactive minerals and radon gas emit x-rays in small amounts. From space, the Sun, other stars, and black holes emit x-rays, but we are protected by our atmosphere. X-rays from space arrive at the upper part of our atmosphere called the ionosphere, where they are absorbed. If all of the x-rays reached Earth’s surface, they would destroy living things and eventually sterilize the planet. The ionosphere makes life on Earth possible.

We don’t think this is just another coincidence. We believe it’s part of the divine design of this planet. X-ray vision is only for comic-book characters and movies.

Earth’s Atmospheric Design

Earth's Atmospheric Design

One of the many things that make our planet uniquely well designed is the atmosphere. Our atmosphere has the right density to burn up the 10,000 plus meteors that speed into it every year. It’s also dense enough to scatter the cosmic rays and X-rays from space, so we are protected from this deadly radiation by our Earth’s atmospheric design.

Also very important, the atmosphere is thin enough to allow light to penetrate so plants can grow. It contains the proper mix of gasses for all living things to use. There is enough oxygen for us to breathe, but not enough to cause dangerous, uncontrolled combustion. It has the right amount of carbon dioxide to allow plants to live and give us the right amount of the “greenhouse effect.” This proper amount prevents too much heat from radiating off into space, keeping Earth at a temperature that promotes life.

The atmosphere is mostly nitrogen, which is relatively inert, but plants need it to grow. Because nitrogen is inert, it’s released to the soil by bacteria and certain plants, such as legumes or by lightning or tectonic activity. The atmosphere is topped off with a layer of ozone that absorbs ultraviolet energy from the Sun to keep us from being overexposed to the harmful effects of UV rays.

When we look at Earth’s atmospheric design and compare it to that of other planets, we realize that God has given us just what we need for life on this planet.

Alone In the Milky Way

Alone In the Milky Way
Yesterday we mentioned an article by John Gribbin in Scientific American (September 2018, page 96 or online HERE.) The title of the article was “Are Humans Alone in the Milky Way?” Although Gribbin suggests that some form of life exists elsewhere in the galaxy, he insists there could be no sentient beings like ourselves. The reasons for concluding that we are alone in the Milky Way galaxy are these “amazing” and “implausible” “coincidences.”

SPECIAL TIMING. The elements that make up a terrestrial planet like Earth are produced from hydrogen and helium by thermonuclear fusion. We see supernova explosions producing the heavy metals that make up a terrestrial planet and life itself, but it takes time for this process to create the necessary elements. Most of the exoplanets we see have minimal amounts of the heavy elements because they are early in their stellar evolution. Even the sun itself is 71% hydrogen and 27% helium with only 2% metals. The timing of putting the materials together to make a terrestrial planet is critical.

LOCATION IN THE GALAXY. The location of a solar system in the galaxy makes a difference. The galactic habitable zone is the area where there is a freedom from the concentration of supernovae. Systems near the center of the galaxy have high levels of radiation in the form of X-rays and cosmic rays. There is a massive black hole in the center of our galaxy called Sagittarius A which produces massive amounts of radiation. Gamma-ray bursts occur in certain places in the galaxy. In our area of the galaxy, sterilizing radiation bursts do not happen.

Recent studies of the galactic habitable zone tell us that it extends from 23,000 to 30,000 light-years from the center or only about 7% of the galactic radius. This zone contains only about 5% of the stars, because stars tend to concentrate toward the core of the galaxy. Our Sun is close to the center of the galactic habitable zone providing rare long-term stability.

TYPE OF PLANET. So far astronomers have discovered about 50 “earth-like planets.” What that means is that they have found rocky planets in the habitable zone that are about the same size as Earth. Venus would qualify as an “Earth-like planet,” but it is an excellent example of how misleading that statement is. Venus has a thick crust with no sign of plate tectonics, no magnetic field, no way to recycle materials, and no stabilizing moon. Our Moon keeps the tilt of Earth’s axis at 23 ½ degrees providing a stable climate.

Realize that all of these factors are just to have a ball of rock in the right place at the right time with the right materials with which to make life. Now we would need to calculate the odds of getting the right chemicals together at the right time in the right place with the right catalyst to make the first living thing. Books have been written about how improbable those steps are. The writers are not religious fanatics, but scientists who are doing the research.

The Scientific American article, concludes that we are alone in the Milky Way:

“As we put everything together, what can we say? Is life likely to exist elsewhere in the galaxy? Almost certainly yes, given the speed with which it appeared on Earth. Is another technological civilization likely to exist today? Almost certainly no, given the chain of circumstances that led to our existence. These considerations suggest we are unique not just on our planet but in the whole Milky Way. And if our planet is so special, it becomes all the more important to preserve this unique world for ourselves, our descendants and the many creatures that call Earth home.”

We must make one additional point. If an intelligent Creator was involved in this process, the probability of a habitable Earth with life on it is 100%. Perhaps we are not really alone in the Milky Way because there is a God who cares about us. For those who might want to consider this option, we encourage you to watch program #6 of the video series available free on doesgodexist.tv.

See Through Objects

See Through Objects
How is it possible for us to see through objects (like air, water, and windows) and not through others (like wood, steel, and window blinds)?

Light is a form of electromagnetic wave energy oscillating in a particular frequency range and energy level. There are many more frequencies (and energy levels) in the spectrum of electromagnetic waves. X-rays are electromagnetic waves at a higher frequency than light. Radio waves from cell phones, radio, and Bluetooth devices are also electromagnetic waves at a lower frequency than light. We can’t see the waves that are above or below light frequencies because our eyes were not designed to see them.

We say that an object is opaque if we can’t see through it and transparent when we can see through it. When some light passes through an object, we say that it is translucent. Wood is opaque to visible-light frequencies, but it is transparent to electromagnetic waves in other frequency ranges. For that reason, we can listen to the radio or use our cell phones or wi-fi inside our houses. Our bodies are partially transparent to X-rays. That allows doctors to use X-rays to check for broken bones.

If our eyes were sensitive to radio waves and not light frequencies, we would be able to see through most solid objects. Then we would not only lose our car keys, but we would also lose our car–and our house too! The things we need to see would be invisible, and all of the electromagnetic waves around us would fill our vision with confusion.

Electromagnetic waves of different frequencies can pass through some materials but not others because of their wavelengths and the energy levels of the electrons in the atoms of the materials. So X-rays can pass through skin and muscle better than through bones. Radio waves can pass through wood, but not through steel. Light can pass through clear glass, but not wood or steel or cookie dough.

The complexity of this system allows us to see those things we need to see, like solid objects that our bodies cannot pass through. It also enables us to see through objects that we can pass through, like the air or water. It even allows us to see through objects which can protect us, like glass windows in our homes and cars. At the same time, it enables us to have cell phones, MRIs, and wireless headphones which use electromagnetic waves that can pass through objects without being seen. This very complex system took some incredible engineering by a Master Engineer.
