Wrong (kinda) Well, yes, there is no edge but there is an edge.

Well, I mean, they spend their very peaceful life zipping around at 299,752,458 m/s till it hits any random atomic nucleus. The thing with ''destined to never be absorbed'' is just the fact that the photon doesn't experience distance. You not experiencing distance is you not really experiencing time.

Its not really accurate to say that infinite time has passed infinitely quickly. The best way to put is that distance for a photon doesn't exist.

Very durable but aren't human.

Tidally locked planet.

Cool story bro. Wonder what kind of human can survive that.

r/telescopes and r/astrophotography are your friends.

Why do you have four separate questions instead of just merging then all into one?

Wow, that was kinda extreme.

I mean, you are electromagnetically polluting the environment each time you use any gadget and you have probably disposed of waste a lot of times over so I'd not say you are off the coast regardless of whether you are brutal because you certainly still are. Everyone is. This species sucks and it's bad for its own planet.

>Let's pretend you could live forever or not die up there, what would it look like?

Then atoms wouldn't decay, so the universe would have to be immortal aka ∞. Kinda strange but for most of it, it would be empty space. Infact, most nebulae wouldn't even be visible as they are either visible in infrared or are only visible through filters from telescopes with far more resolution/seeing capabilities i.e Hubble. Only some Nebulae like the Tarantula nebula and the Orion and Rosette nebula would even be visible and nebulae are pretty sparse so it would still end up looking like empty space from the inside. You would barely just notice you were inside one. But hey, one quick tour through the galaxy wouldn't be so bad.

And the said truth is that you are part of that virus from Earth headquarters.

And fun fact, for you it would be instantenous. So even FTL is possible, it will be instantenous. But then again this is forever.

Yes but the thing is we don't know the limit precisely. Eventually, as you add more and more protons and neutrons together, they stop being bound together. This is known as a Proton or Neutron dip. Idk how much 500 protons would even be like but it'd have a very very small lifetime. Micro if not nano or picoseconds.

Depends. There's lots of reasons it shouldn't work yet it isn't forbidden by relativity. The main problem with it is that it requires negative pressure and we have no idea if it even exists. Negative pressure= negative energy=negative mass. Literally, -1 kg.

And even then, we would only be able to contract and expand spacetime to a finite extent before we run into the fact that it would require more negative pressure than the energy in the observable universe. That's impossible.

When we mean ‘falling’ we talk of being captured in a gravitational well and being forced to move around it if the body is rotating. And you can fall in accordance as long as you share a barycenter. So yes, we are technically falling in the Local Group's gravitational well.

>If everything is falling does the expansion of space mean there’s always room for everything to continuously fall?

Eh..... roughly yes.

No. The math doesn't work out the same. You can use Classical Physics to explain things like Feynman Diagrams and you can't use QM to explain the universe at a large scale.

That's only their perspective. To us they move but to their perspective, distance doesn't exist at all as the time they were created and the time they were emitted are the same time. It's just a consequence of Relativity.

Since your question assumes the multiverse existed, then the big bang in such a case was the universe borrowing some energy from the interuniversal distances. Now,this energy would be internuniversal, so there was no energy escaping.

That's not possible theoretically either. The geometry of black holes makes it that the speed needed to escape is basically ∞. All pathways simply lead inside. There is no “theoretically.”

No. The geometry of black holes is curved that every direction leads to the singularity. Unless that speed was ∞, no.

That's not anti matter. It's dark matter. And if it was anti matter then we wouldn't exist at all. And yes we don't know what it is.

Because of our biology. Robots can do just fine with ×3 times less gravity and no water and food.

A dimension is really just a fancy name for a direction. The 4^th dimension is time. Although if you are talking about a literal 4^th dimension, hypothetically the string theory predicts 26 dimensions with 22 of them being hidden at the quantum level.

Who the fuck gives a shit

Yes Anything with carbohydrates are bound to burn basically. There's a really famous expirement where you have two grapes in a microwave. You expose them to microwaves and they create plasma.
