Oh, so we'll get ripped apart. That's fun too, I guess.

What?

I mean seriously what?

Just let Havoc have his own little world. Whatever makes him happy.

There's multiple theories. If the universe would shrink it would all condense in a big pile of energy. If it forever expands then eventually (in billions and billions of years) stuff would start to disintegrate.

I'm no scientist, I'm just saying some of the stuff I happened to have read.

If it forever expands, the most likely explanation is the heat death of the universe via entropy.

Not

The universe tearing itself in two

How does that even work?

I think Havoc meant that if the Universe shrunk, we'd be ripped to shreds by the resultant force.

Don't get too hung up on poetic language versus descriptive language is science (says BM, the master of getting hung up on that).

In a few more eons (I don't know the actual time frame) most of the universe will have sped beyond the extent of the visible universe when the space between us is expanding faster than light can traverse it. If we existed in that period, it would be impossible to know about the big bang and most of cosmology, because all the evidence will have been erased.

I figured matter disintegrating on an atomic level. Atoms getting ripped from one another by faster and faster expansion.

That was the mainstream opinion until recently, when an article was published that suggested that the universe's expansion is accelerating fast enough that the rip will happen before heat death. I don't know if that's widely accepted yet or not, though.




It's not that the universe would tear in two. It's that everything would be too far apart for gravity to hold it together. Each star would split apart from the rest of their galaxy, the planets would fly away from their stars and, eventually, the stars and planets and all matter would fall apart.

That's kinda sad :(

Well it's been proven that in a vacuum of absolutely nothing, certain particles/atoms appear. Out of literally NOTHING.
... And yeah. That's all I got. The absolute beginning of everything.
Maybe all these little particles and stuff very slowly got bigger and bigger, forming gasses and then solids, and with all that pressure it eventually caused the big bang?
... Who knows. I really wish we had the answers though.

Yes, but then they instantly disappear in to nothingness. Both sides of that equation must be true for Quantum Theory to hold.

Jesus had the answers, but we killed him.

The Prometheans are so going to make us pay for that.

Ah, thanks for that. I didn't know about them vanishing, but it makes sense.

What shape is the universe? If it is ever expanding, then it isn't yet infinite because in order to be still expanding there needs to be room for it to expand.
So what happens when you get to the edge? Is it spherical so you just go round and round?
Does one get to the end and then there's nothing but black?
What's the definition of the universe? Are there things outside of it?

Sorry if I'm asking dumbass questions, I love space but I'm not well versed in the subject.

No-one knows if the universe is finite or infinite. No-one knows what shape it would be on the outside. That's because all we're aware about in the universe is that range of it that is visible to us, and that is limited by the speed of light and the age of the universe. The universe is about 13.75 billion years old, and we can only see those parts of the universe that were close enough for light to have reached us in that time.

In terms of expansion, it's not necessarily the universe itself that is expanding (although that might be happening too), but rather that everything in it is spreading apart.

Engineers, not Prometheans.

Prometheans are the new badguys in Halo 4: The Quest for Holographic Pussy.

D: I though he meant those Halo 4 guys!notrly Give my rep back

WHATEVER IT'S STUPID NO MATTER WHAT YOU CALL THEM.

So, how exactly do atoms appear out of nowhere? And why just in that particular spot?

Here you go.

Good luck.

My mind just imploded

I found this very interesting, though it's a long video.

There's also the Protheans from Mass Effect. You know, the mysterious dudes who turned out to just be jamaican.

I did find the Jamaican accent to be a bit silly.

But American aliens are just fine?

When making any kind of fantastical fiction you are stuck with having to present creatures that come from "elsewhere" as understandable. To do that you ask that the user/viewer suspend disbelief enough to accept an accent that is similar to the one they are already accustomed to. However, when you start asking people to accept multiple "familiar" accents then the viewer starts seeing these different races as "Jamaican," "British," or "American." Add on top of that accents which inherently sound silly to begin with (this is a personal thing. I personally think the Jamaican accent is funny sounding, especially when faked) and you begin to lose suspension of disbelief.

Sometimes it can be quite funny.


I know what you mean, though, but it's hard for them to "create their own accent", and hearing the same ones coming from aliens all the time can be tiresome.

It's a fine line, and there is really no "right" way to do it. You just have to try to avoid making them sound silly as best you can.

They should have gone with South African. That accent sounds alien already.
