10 Facts You Didn’t Know About The Universe

Posted on

The universe is massive and appears to contain infinite wonders. As our technologies become more advanced, we are poised to discover even more and perhaps prove our current theories wrong.

Still, our observations and studies so far have revealed many strange phenomena in space. Surprisingly, one of the most complex objects in the universe is right here on Earth—and even closer than you probably imagined.

10. Galactic Years

We all know that a year on Earth is 365 days, but there are also galactic years. For our entire solar system to make one orbit around the Milky Way, it would take 230 million years. This means that we will not make an entire orbit of the Milky Way in our lifetimes.[1]

The last time that our solar system completed its rotation, the human race was not even near existence yet. In fact, dinosaurs were still alive during that time. The next time that our solar system is in the same position in its orbit as today, human beings will probably not exist anymore.

It is incredible to think about just how big our galaxy is. It is so small compared to the entire universe. Just think if the universe is infinite and our galaxy is also in a rotation around it, how long would the galaxy take to complete its orbit?
