Fuck the Fire Department!

It’s a bad look, but not extremely so IMO.

All my homies hate tankies.

Nice!

Does the pope live in a glass house?

I like “The old man the ship”

You are allowed to call it a planet. Everyone has the right to be wrong about stuff.

It’s a bit more complicated than that. One of the consequences of theory of relativity was the realisation that time and space cannot be separated and it only make sense to speak of “spacetime”, a four-dimensional continuum rather than just three as we thought until that point. As far as I understand it, time is not really different from the other dimensions, it just seems that way to us.

I heard an explanation that has to do with entropy - the total amount of entropy is always increasing (I’m not going to even try to explain this since I only barely understand that myself) and the act of encoding information (whether we’re talking a brain forming a new memory, a computer storing some data, or me writing this comment) is a process that always increases entropy, therefore any kind of memories can only be of things in the past rather than the future, and so every moment of our lives feels like “now”, the boundary between the written and the unwritten. I don’t think we’re actually moving in time. It’s just an illusion.

That said, while my earlier explanation is simplified and probably contains a ton of inaccuracies, I’m fairly confident it’s accurate in broad strokes. This comment though, I’m not nearly as confident this is the current scientific consensus. Just what makes sense to me, so take it with a grain of salt.

If you’re interested in stuff like this, I cannot recommend The Elegant Universe by Brian Greene enough. Unlike me he’s someone who actually knows exactly what he’s talking about and he explains everything much better than I ever could.

OK, so what we discovered was that if we look far into the universe, all stuff is moving away from us (we can measure that using the famous red shift). Additionally, the farther something is, the faster it is moving away from us.

Now the simplest explanation would be that the Earth just happens to be exactly in the middle of this expansion. However, it is much more reasonable to assume our location in the universe is not special in any way and that you’d see things moving away from you if you did these measurements anywhere else. If that is so, the universe is expanding, everywhere. There’s more space in the universe every second and there’s still the same amout of matter, hence it is becoming larger, emptier and colder.

The next step is to look back and think of how the universe looked in the past. Since it’s getting bigger and bigger, it must have been smaller before and if you go back in time enough you’ll find a tiny universe that still has the same total amount of matter in it, just densely packed into possibly just a single point. Hard to say what preceded that moment, but we can predict a universe which started as an incredibly energetic singularity which exploded out and has been growing ever since. We call that moment the Big Bang and if anything, that is the centre from which everything is expanding. Not found somewhere in space but in time.

Back to the balloon analogy, the centre would be the deflated little thing you start with. Maybe a better analogy would be the little clump of molten glass at the end of a glassblower’s pipe. He begins to blow, the big bang happens, expansion starts. Fast forward 13.7 billion years (which happens to be today) - the glass has expanded into a large spherical object and there’s some tiny people living on it.

They only live on the surface of the glass and the sphere is so huge (or they are so tiny) that they can’t even tell that their world is spherical. They measure distances to some other specs littered across the glass and find that they are all moving away from them, faster the farther they are. Their universe is expanding, but where is the centre of expansion? They cannot point to it, because they only live in two dimensions, fully defined by the sufrace of the sphere. But if they could point in a direction perpendicular to all the spacial dimensions they know, they could point to the point where the sphere started, long in their past.

So the right question is not form “where” the universe expands but “whence”. The Big Bang. The very start. Somewhere far in time, which is just another direction, perpendicular to up, left, forward.

Double S even.

“Weaker than Weak”.

No, for the same reason you can’t find a point a balloon is expanding from on its surface. Everything is expanding everywhere.

Nah, this thing with the planet moving under you is stupid because it assumes a fixed reference frame which is not a thing in our universe. Any movement is always relative to something. You can’t just “stay in place”. Having the Earth move from under you is very arbitrary.

It’s a goddamn minefield, especially for someone like me who hates excessive censorship.

No idea, really. See my other reply to daggermoon.

Worth pointing out that for the rest of the world this is often hard to navigate. Americans have a reputation for excessive self-censorship based on pearl-clutching, with “the F word” or “p*rn” or censoring nipples.

So sometimes actual strongly hateful or dehumanising language gets dismissed as another example of oversensitity.

“Japs” was used by Americans during WW2 so it has pretty negative connotations there.

The lizardmen quotient probably goes down with age.

Is that supposed to prove Americans are not a bunch of cowards? Because it does the opposite.
