I have never heard that causality slows down in a medium. I understand the use of "speed of causality" to refer to the speed of light in a vacuum, and while I'm aware that light slows down in air, water, etc I'm not sure it has ever been shown that causality itself slows down. My understanding is that also light slows down just because it's captured and re-emitted by other particles. Though I would be happy to learn something new if my understanding is wrong.
That said, the OMG particle stuff was very interesting, thank you for sharing.
I absolutely agree, but in this climate any vote swayed from Biden is a danger for the entire planet. I don’t particularly like a two party system, much less a one oarty system.
It’s not just climate at stake, there are basic liberties and some level of worldwide stability that we used to give for granted, which are going to be a thing of the past if Trump goes back to office.
For fks sake, the detachment from reality in this comment is astonishing. Would it be ok if I raised you as meat and then slaughtered you when you where 15 years old if I guarantee you that you would have a decent life in the meantime? Of course not, it would still be pretty fucked up.
Is there a temperature so hot that relativistic effects are noticeable?
