Comment on "Theory" of Evolution (SMBC)
booly@sh.itjust.works 3 months agoThen there’s the theory of gravity, this is our attempt to explain why gravity exists and why it does the things it does.
Not just the why, but also the what. We didn’t observe gravitational waves until 2015. People have proposed the existence of dark matter and dark energy because observed gravity doesn’t behave as our models would predict at certain cosmological scales.

I like to think of it in this way: What we call dark matter isn’t the cause/source, but the discrepancies we’ve seen in our observations/data. So anybody who says dark matter doesn’t exist is plain wrong, the discrepancies are there plain as day. And it isn’t a single thing, it’s many discrepancies in a lot of data. Now the name is probably not as good, as it isn’t clear it’s actually matter and it isn’t dark but simply doesn’t interact with EM radiation. So we can’t “see” it directly, only indirectly. The name is so poor, it leads to a lot of miscommunications. But the fact is, the data doesn’t match up. So there has to be something there. And that’s data going back almost 100 years.
