If you took out everything in the universe except for two planets and placed them at opposite sides of the universe, would they still attract one another through gravitation?
But it would take some incredibly long time for it to occur, because gravity can't travel faster than C, right? And isn't the universe expanding faster than light? How would that affect it?
If there were only two large bodies in the universe, and they (obviously) attracted each other by gravity, then the universe wouldn't expand.
The universe would be pulled inwards by the most powerful gravity (the two planets), so at best it would be hourglass shaped.
Currently, there's so many gravitational bodies in our universe that it just has to continue expanding to accommodate the flux and temperance of those bodies.
TL;DR the universe expands because it has to, in order to keep existing.
can expand on this more if anyone wants me to.
Happy to give it to you.
The universe, as in all widely accepted models of thought, is a 'constantly expanding anomaly'; which, currently, is true.
But that's simply because of the sheer amount of Force present in the universe. There's a goggleplex of celestial bodies in our universe, and as such, it has to constantly grow larger and larger in order to accommodate these gargantuan planets/planetoids/every thing else; and, as a result, more and more get formed.
If our universe had two single planets and naught else, then it would have no need to expand, to grow, and to produce more.
It wouldn't be an 'ovoid' shape, it would be an hourglass figure. The two planets would have the edge of the universe relatively close to them, but it would flare out in the between space while the planets were gravitating closer together.
And I do have to apologize for the use of the word 'gravity' in my last post, it was the quickest way to get the facts across without having to go on a long explanation within an explanation.
B-b-but what would happen if you went to the edge/past the edge of the universe
Thanks for the explanation though!
M8 dark matter is causing the matter in the universe to expand and spread out, the universe itself isn't expanding
The three spatial dimensions we know are infinite and limited at the same time. They are infinite in that if you go far enough in one direction you will end up on the other side. They are limited in that because of this there is a maximum distance that can be reached; if you had an incredibly long measuring tape eventually it would reach itself again.

No, space is flat. It extends infinitely and doesn't curve back on itself.

space between objects in the universe is growing in size, this is not visible between say your house and your friends house, but when you're dealing with trillions of light years is is apparent.
Because of thise, the space between 2 objects is increasing faster than light can pass through it (so long as you take 2 objects sufficiently far away from one another) and so yeah, the universe is expanding faster than light.
Do you think that her skin would not only look like plastic, but also feel like it?
Or is her whole thing dependent on airbrushing and/or makeup? I mean, aside from the tits and waist, which have obviously received a generous amount of cosmetic surgery.
I maintain that fucking her would be just like fucking a realdoll, except it can clean itself up afterward.
On the other hand, she's spent so much of her life and money to gain her fucked up doll-like visage that I wouldn't be surprised if she just had no interest in sex (would ruin her makeup, sully her "perfect" skin etc.), instead only using her (subjective) sexual attractiveness as a tool to gain social power and influence.

Welp, disregard that, I suck cocks.
Thought it was that Ukrainian model (or her mom) who made herself look pretty much exactly like this silicone doll.
