Everything is being stretched because of dark energy, but since scientists can't yet explain dark energy, they can't pinpoint the reasons for the expansion of the universe either.
I actually made a small error there. Einstein's theory of relativity wasn't discarded, just the part about a cosmological constant. NASA's website didn't provide any specific names of scientists.
Great presentation! I am curious what else you know about quintessence? Is this something that is very important and they are actively trying to learn more about?
Quintessence could be very important! If it exists! Right now, it's just a possibility that there is a dynamic energy fluid in space causing the universe to rapidly expand. And yes, scientists are actively researching and theorizing because it could be the answer to why the universe is expanding!
"Einstein began by applying his field equations of gravitation to what he considered to be the entire universe. The field equations were the mathematical essence of his general theory of relativity, which extended Newton’s theory of gravity to realms where speeds approach that of light and masses are very large. But his math was better than he wanted to believe—his equations told him that the universe could not stay static: it had to either expand or contract. Einstein chose to ignore what his mathematics was telling him.
The story of Einstein’s solution to this problem—the maligned “cosmological constant” (also called lambda)—is well known in the history of science. But this story, it turns out, has a different ending than everyone thought: Einstein late in life returned to considering his disgraced lambda. And his conversion foretold lambda’s use in an unexpected new setting, with immense relevance to a key conundrum in modern physics and cosmology: dark energy." from an article written by Amir Aczel
NASA's website provided great optimism on this point: The universe will continue on for another few billion years, so we have until then to figure it out.
But really, there could be a miraculous break through tomorrow, or it could take lifetimes. The technology we have currently can't detect dark matter.
how does dark energy help rip apart matter while the universe expands?

DeleteWho's theory was theory four that thought Einstein was wrong?

DeleteHow did Einstein figure out that empty space was not nothing?

Will scientists soon figure out what dark matter is?
