It's been a long time, friends, but I am back. I am not an expert in terraforming, but to change the atmosphere, we need to cool down Venus first. Kurzgesagt has an excellent video on putting angled mirrors into orbit to effectively put shade on Venus and freeze the carbon dioxide in the...

The following is not directed to anyone particular, but it is rather directed to everyone in general: Can we please stop bashing on "scientists" and "experts"? They are not omniscient, they do not know everything - rather, they, like every proper scientist, first make observations, then make...

Just wanted to make a small point here - General Relativity posits that gravity is a result of the curvature of spacetime, and therefore spacetime is curved. But, you are correct that space is not that much curved to make us able to see ourselves. Although I am not sure if I completely...

Firstly, I do not understand how objects spinning in a system make it plausible that the entire system is rotating. Secondly, I do not think the revolutions of the planets and stars have anything to do with the rotations. The Earth does not rotate because it revolves around the sun, it is...

I think I am a bit late, but well, I will still enter the fray because this is an interesting thread I dunno, I haven't ever been thrown out of the window with wind speeds of more than thousands of kilometres per hour making me head right into the vacuum. The following is my opinion on this...

I have a vague memory of a similar thread, but if I remember correctly, the thread was closed for further replies. This is not a continuation of that thread, but a new one, to restart it over again, the age-old question of modern astrophysics: what happened to antimatter? Why is there more...

Hey there, that's an interesting question. It is true that light doesn't feel time, but, blackholes aren't defined as objects having "infinite gravity", they are defined as objects having infinite density. It's basically mass smashed into... zero spacetime, nothing;I know that makes no sense...

I think I misworded (is that a word? What is a word anyway, anything that is considered to be?) in that sentence. "Realised" would be a better word. I would say that we don't know, rather than don't understand. :)

Not exactly... I am referring to the hypothesis that spacetime didn't exist before the Big Bang, that is, when matter and antimatter started to exist. The point is, if there is no matter, then there is no space or time relative to anything, as absolute space or absolute time or absolute...

That is an interesting food for thought, Cat. Although I don't understand the "<5" part about what you are referring to (maybe that's a reference to the thread you are posting it in), I get the gist of it. But I do get that you are proposing that the Universe is not "the Universe", it's now "a...

TBH, expansion is not really the hardest question. We all know Newton and his laws. Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force...

Cat, I have a few questions. Where exactly is(are) the "lagrange" point(s) of nexus(es?) in the cycle of the Universe? Does that refer to the point(s) where entropy is the maximum and where it is the least? I mean, the point where time starts to go backward instead of forward and vice versa...

This theory still does not solve everything though, it still does not describe the starting point of the "backwards universe" or the ending point of our universe and does not solve the problem of entropy or singularity. :)

This is an interesting thread. First, let me talk about the original post. The idea that the Universe was a singularity at the time of the big bang is merely a theory, or rather say, a hypothesis, because we can never scientifically observe or prove it, because no matter what, the Math always...
