Is the Universe Getting Bigger?

We love hearing from you and answering your questions! Pia B. asked,
“Is the universe getting bigger?”
Great question, Pia! We can’t see the edge of the universe, so we can’t directly observe whether it is expanding or not. However, there is at least some evidence that the universe is expanding.
The evidence for this comes from our view of galaxies. If the universe is expanding, then most galaxies should be moving away from us. If it is not, then the galaxies should not be moving away from us.
It turns out that when we look at galaxies in the universe, many are moving away from us. We know this because the light from those galaxies has longer wavelengths than they should have if they were not moving. Most (not all) galaxies have these longer wavelengths.
Based on the observed longer wavelengths, we interpret the universe as expanding. There are other potential explanations, but the universe expanding is the simplest one.
Did You Know?
Evolutionists believe that “around 13.8 billion years ago, the universe expanded faster than the speed of light for a fraction of a second.”1 They call this cosmic inflation. They say energy from cosmic inflation led to the big bang, and that’s how life eventually began.
Of course, they weren’t there to observe the universe’s beginning, but there is one who was: God. According to his Word, the universe and life began when God spoke it into existence, only thousands (not billions) of years ago. We can trust that the Bible is true, no matter what ideas humans come up with.
Do you have a question about the Bible? Ask your parents to help you submit your question today. We’d love to hear from you!
