Re: What IS space?
Space technically does not exist, as it is the absence of matter and energy.

Not necessarily. If there was dark matter all around, we'd be pulled apart and imploded at the same time. It's just space. It takes quite some time of watching physics documentaries and reading cosmology and quantum mechanics books to understand it. I've been asked this several times, and I can't explain it. It's like trying to explain matter or light, or sight. You have to study for yourself and think about it for most of a year to start to understand this stuf. Anyway, just remember that Confucius said "To study and not to think is labor lost. To think and not to study is dangerous."

Re: What IS space?
i told you guys scientists call what is inbetween the planets "dark matter"
there is only one discovered place in the universe that has NOTHING, not even dark matter

no i mean where there is not matter there is dark matter or simply nothing
dark matter couldnt be all around, as there is air around us. if matter already occupies a space, common sense says that more matter cant do that too

This is incorrect. Space is, in fact, a false vacuum. This doesn't mean that it's not a vacuum. It just means that is exists. It's complicated. If I were to try to explain it, I'd be on page 50 and it wouldn't be half enough. It's theorized that if a real vacuum were to be in the universe, it would expand and swallow everything in existence.

Actually, space is not a pure vacuum.

Re: What IS space?
When a pure vacuum is created, loads particles rapidly pop in and out of existence to fill the space.

Re: What IS space?
Space is invisible mind dust.
Ask me what I'm doing, wait an hour than roll a die, if it's 4-6, I'm playing Skyrim, if it's 1, I'm eating, if it's 2-3 I'm programming.

Re: What IS space?
Ok, to clear some stuff up, space is considered to be a vacuum void of matter and energy. The problem is, the universe is accelerating and it can't be explained if space is simply a vacuum. So what we've hypothesized is that there is matter (dark matter) that does not emit an electromagnetic energy (radio waves, micro waves, infrared, visible light, UV light, x rays, gamma rays, etc.) and so this extra mass that is immeasurable by us because we have no way of observing it is pushing the universe apart. Another reason the universe is accelerating is dark energy. However, dark does not mean the same thing as it does in dark matter. In this case, it simply means we don't understand it, it's mysterious.
So to sum up:
--Space has been considered a vacuum up until recently, and now is hypothesized to contain matter and energy that we cannot observe.
--The matter we cannot observe is called dark matter, where dark means that it does not emit anything that we can measure and is therefore completely invisible to us.
---The energy we cannot account for is called dark energy, where dark means that we have no way of explaining it, we simply have to say it's there in order to explain the universe.

Of course not.
If time travel did exist, we wouldn't be able to go to the past because we have already experienced it, and going to the past would change that experience, which is impossible as we have already experienced that experience and we cannot experience something in the past twice.
And if it did exist, there would be no point in going to the future as things would only get worse than they are now and you wouldn't be able to go back, as the future would become the present and your old present would become the past. And we can already go to the future by cryogenically freezing ourselves, preserving our bodies until someone figures out how to bring the dead back to life, therefore making time travel pointless.

Actually, it is possible to go into the future. The faster one travels, the slower time goes for that person, so everything else that isn't travelling at that speed will be going through through time at a faster pace comparatively.

Yeah, but its really messed up, because you go to change something, you change it, and then you have no reason to have gone to the future, thus your past self wouldn't have gone and you most likely won't exist anymore.
Or something like that.

Heck, anything can be faster if you compare it to something.
And yes, we are constantly going into the future. But is that truely 'time travel'?

Your past self still would have gone because what you did wouldn't affect the past, or the past self's present. The change would only occur in the future, where you are currently at.
But what's a huge plot hole for science fiction writers is where a person in the future recieves a message from the past that wasn't there before, as it must have been there the whole time due to the message being left in the past. The only way this could happen is if somebody set a timer for the object to appear at that exact moment the person needs to see the message, which would be near impossible due to the person in the past not knowing who will recieve the message.

Re: What IS space?
Why not to make a Time Machine.
- You go back in time.
- Someone else finds the time machine in any time in the future (time never ends, so all possibilities will occur)
- They go back in time
- They kill you in the past
