This is an Article made by NASA. It's about the dark energy of our universe. We all think that the universe will keep expanding. But around the 1990s, it became fact that our universe has barely any density. This might stop the universe's expansion and recollapse. This means that the universe has collapsed before. This surprised me. I thought the universe came into being with the Big Bang Theory. But apparently, the universe existed before Earth came to exist. This brings up many questions, like How was Earth created? or How was our universe created the first time? Anyways, there's a theory that was long forgotten that might explain why the scientist thought gravity was constant. It is Einstein's theory of gravity. It stated that gravity never changed, otherwise known as cosmological constant. The scientists have come up with a new theory. The solution to this theory is called dark energy.
With further research, scientists have discovered that dark energy takes up 68 percent of our universe, while dark matter takes 28 percent. This practically changes many things about how we will now see the universe. For one, this means that Earth's materials are very rare, and can't be reproduced in any planet. Not yet, at least. Furthermore, it means that if Earth explodes, there would be no more life in our universe, except for the water streams on Europa. Yet more problems arise with the discovery of dark energy, The problem with finding out whether the quantity of dark energy within our universe in specific numbers continues. Physicists tried to solve the problem, with the numbers came out with 120 too many zeros. This comes to show that human beings don't quite know everything about the Final Frontier.
This is a cool and interesting topic. I learned a lot from your post and I found it very helpful.
