What is the end of outer space?

[EternalGamerz]

There is no end in outer space. Although space is super huge no one know the size but im guessing space is round like planet so there for space is a huge sphere. If we were to send a rocket out for zillions of years in a straight line from earth. It would eventually come back around the other side of the earth no doubt.

We don't know if there even is an outer space. It's sadly all theories. Saddens me that we will probably never get to know.

You guys are (probably) really uninformed about the theories that are valid and accept in the physic science at this moment. I currently do not have enough battery to explain those theories nor do I feel most people here are actually interested to really know so. Lets just say, there are ideas about this. Google if you want to know more.

there is none

[Trol553]

I cant imagine.

That's a very bold statement. As you said yourself, it are all theories and there are hundreds of scientists who think that their theory is the most plausible.

Hubble's Law, the "end" of space is expanding faster than the speed of light. If you were at the pinpoint end of space then you would not know because at that point space would expand really, really fast. Also if you sent a rocket out for zillions of years it wouldn't "come back around" unless it came across a worm hole (if they exist).

there is a certain distance we can see, but space does not end.

It has to be so huge that you Cant even See everything with light speed

Yes but it are theories based on techniques and observation. One very famous theory is the multiverse, that there are more universes like ours. All consisted made out of an extremely big amount of energy focussed on one point.

Doesn't really matter
Universe expands at the speed of light
Even if you departed from earth traveling as fast as light you'd still never get to see the end on any side, if there is a side to it.

We are made of star dusts!!

Long story short, we don't know. But if the universe really wrapped around, the explosion from the big bang would be coming back to hit us... which wouldn't be good. But as far as we can tell it's still expanding.

[Copperhorse]

There are 2 theories. The first one would be that eventually the universe is going to collapse into one small area, and have another big bang, which would be a repeating process of billions of years. The other one would be that the universe will expand forever, because gravity would not be able to pull everything together due to the fact that the dark energy in the universe overcomes gravity.

Either way, it's pretty fucking mind boggling.

The universe is about 13 billion years old. Say you live 80 years. You have lived .000000006153% of the universes's lifespan. It's amazing how much shit happens before and after we die, you may think our technology is rapidly expanding etc. But in the grand scheme of things it probably is nothing when you compare it to the life the universe or any object in space really.

I'm 100% sure that the human kind will be dead before we know the answer to your question
