horizon. Next Sentences: That’s why you can’t see anything past the horizon! But, in theory if there were something that far away and travelling at less than or equal to the speed of light, they would eventually be able to get here because their signals have time to reach us from where ever it is. Sentence after next paragraph: So maybe all we need are some really good telescopes and then we’ll find out what else is beyond our cosmological horizons? It just might take a while before those telescopes are powerful enough for us to know for sure.. – “Why Can’t We See Past The Cosmological Horizon?” by Tia Marie D’Angelo *Some scientists hypothesize*In the past few decades, scientists have discovered that there are parts of the universe we will never be able to see. This is because light can only travel so far before it becomes too faint for our telescopes and other instruments to detect. In fact, if you were sitting in a spaceship moving at the speed of light and looked out your window, you would not be able to see anything outside of your spaceship! But why don’t we know what’s on the other side?
This article discusses some reasons as to why we cannot see past the cosmological horizon.
There are two main reasons for this. The first is that the universe is constantly expanding – meaning it’s getting bigger and bigger all of the time, which means we can only see so far before it becomes too faint to detect by our instruments. Second, light has a limited speed that tells us how fast things can move from one point in space to another (ie. if there’s something on the other side of the horizon travelling at less than or equal to the speed of light). So when you look out your window and try seeing what else might be past where you’re looking, no matter how hard you look, everything will appear as though it were just beyond your line-of-sight because they’re really beyond that cosmological
