Einstein’s general relativity is currently “the law” of gravitational acceleration in the universe. This, however, predicted that the attractive force of gravity pulls all matter together, wherefore subsequent to the “Bang” the expansion of the universe should be observed to slow. This has not been observed, however, and instead, recent evidence confirms the expansion of the universe appears to be accelerating. To explain this, another revision is now necessary and a few theories have been proposed. What seems to be the common opinion now is that 96% of reality is actually unknown and undetectable substances called “dark matter” and “dark energy”. Making this assumption is said to be the only way to confirm general relativity is still a “scientific fact”.
So you are full of shit. What a surprise. I wish I had called it befo- Oh, wait, I did.
Dark matter has nothing to do with the expansion of the Universe. In addition, dark energy is not an assumption; it's a placeholder name for whatever is causing the expansion to accelerate.
Anyway, I'm now done with your posts. Gonna try to find an "ignore" button. See ya!
Umm... I think this person is confused. May want to check your source. Both "darks" are assumed to explain why the expansion is accelerating and not slowing down. Yes, I agree about them both being "placeholder" names because they have not actually been observed, so they cannot claim them to be "matter" or "energy". Neil Degrasse Tyson actually said they would be better off labeled "Fred" and "Wilma" because we know nothing about what theyactually are.
