Other Galaxies Beyond the Milky Way

Other Galaxies Beyond the Milky Way

In the early 1920s, Edwin Hubble (in whose honor the Hubble Space Telescope was named) was peering through his telescope. As he examined many of the points of light that astronomers had thought were stars or “spiral nebulae” in our galaxy, he realized that they are much more than that. He discovered that they are other galaxies!

By the mid-1920s, everyone knew that our Milky Way is only one of a myriad of other galaxies. Since then, we have learned many things about our galaxy, but we still have much to learn. The Milky Way is a spiral galaxy in the shape of a large saucer. Other types of galaxies–which are the majority–cannot support planets and therefore are not suitable for life.

We are spinning around our spiral galaxy at about 120 miles (200 kilometers) per second. At that rate, it will take us 250,000,000 years to make one complete orbit of the galaxy. We can’t take a picture of the entire Milky Way because to travel outside of our galaxy would take many thousands of years–even at the speed of light. We can take pictures of other galaxies, and this one is another spiral galaxy named M74.

The Milky Way’s disk is about 100,000 light-years across, and we are about 27,200 light-years from the center. It’s good that we are not near the center because that is the location of a giant black hole. It is also fortunate that we live in an area of the galaxy that is not crowded with quasars, black holes, and other major hazards. The galaxy area with the most gas and dust is less than 500 light-years from the central plane–far away from us. That means we are in an area relatively free of debris, so this is an excellent spot to get a good view of our galaxy as well as other galaxies and stars.

Is it just a coincidence that we are in the right kind of galaxy and in the best position in that galaxy to be safe and to be able to study and observe the universe? We think God wanted us to be in a hospitable place where we could see the majesty of His creation.

Science Confirmed Three Bible Statements

Science Confirmed Three Bible StatementsAt the beginning of the 20th century, there were three scientific “facts” that disagreed with the Bible. In a little more than 100 years, science confirmed three ancient Bible statements. The Bible was correct, and science had been wrong.

Until the early 1900s scientists believed that the universe was eternal and existing forever with no beginning. They also believed that on the large scale the universe was unchanging. Thirdly they believed that we would find subtle changes to the laws of physics if we could travel throughout the universe.

In contrast to what scientists believed, the Bible clearly says that there was a beginning to the universe. (See Genesis 1:1.) The Bible also says that the universe is dynamic as it was being “stretched out” by God. (See Job 9:8, Isaiah 40:22, 42:5, 44:24, 45:12, 51:13, and Zechariah 12:1) Thirdly, through Jeremiah the prophet, God declared that His laws of the universe are unchanging. In fact, God used the unchanging nature of the physical laws as proof that He would keep his promises. (See Jeremiah 33:25-26.)

Things began to change for scientists when Albert Einstein issued his theory of special relativity in 1905 and then his general theory of relativity in 1915. Einstein showed that the laws of physics are constant and unchanging no matter where you are in the universe or how you are moving through the universe. His calculations also indicated that the universe is dynamic, either expanding or contracting. However, like other scientists of his day, he could not accept that idea. He added what you might call a “fudge factor” to his calculations to make it look like the universe was static. He later admitted that was the greatest mistake of his life.

A few years later in the 1920s, Edwin Hubble discovered that there were other galaxies out there and they are moving away from us. He also found that the farther away they are, the faster they are moving away. That means that the universe is expanding. It is not a static universe but one that is being “stretched out.”

There is another implication of Hubble’s discovery of the expanding universe. Since the galaxies are moving away from each other, what would that mean if you could go back in time? At some earlier time, they were all in one place. In other words, the universe had a beginning, a singularity as scientists call it. Many scientists were not willing to accept the idea of a beginning. One of the reluctant scientists was Sir Fred Hoyle who jokingly referred to it as a “big bang” theory.

But in 1964, Arno Penzias and Robert Wilson discovered the cosmic microwave background radiation which further confirmed that there was a big bang type of beginning. Space-based experiments finally confirmed it in the twenty-first century. Now, virtually all scientists accept the idea of a beginning.

So, thousands of years ago, the Bible stated that the laws of the universe are unchanging, that the universe is expanding, and that there was a beginning. Science has now recognized the truth of those statements. Science confirmed three Bible statements, but many scientists are still not ready to accept “In the beginning God created…”
