Does time exist in space?

I think you've interpreted me wrong. I didn't say that time speeds up everywhere, not at all. I was specifically referring to the person travelling at speed.

you said this,
then after you had spent one week on the ship, the rest of the universe would have aged much more than one week.

which is equivalent.

By the way, the person is not travelling at the same speed according to all observers so 'the rest of the universe' will not have aged at the same rate, and infact some parts may have aged less!

So for you, when travelling at speeds approaching that of the speed of light, time slows down. I could have given more specifics and information, but in a post like this on a general forum, that would just confuse things more than necessary.

Incorrect again. The statement is meaningless without talking about reference frames. time does not 'slow down for you'. For you, time is always the same.

You're arguing pedantics! I'm not trying to give a degree level accurate answer here, but merely an overview of the effects.

I never said the rest of the universe would have aged at the same rate, merely that traveling that fast would slow down time for you. And you know exactly what I mean by saying time will slow down for you, you're just arguing wording again.

But as I said before, I'm not trying to give an exact answer covering all situations.

Not on a forum like this! I'm trying to explain the general concept, not the specific details.

If you want to regurgitate a textbook on here to answer a simple question be my guest. But I'll give a quicker answer which will cover the question asked.

Edit - I should probably mention that I'm not disagreeing with you. What you're saying would give a more accurate answer.

No, that would be a light year :p

A parsec is also a measure of distance.

The Star Wars reference is due to to Han Solo's claim that he did the Kessel Run in 12 parsecs, thus implying that it's a unit of time (so not quite velocity, but still a misuse of the term).

However it also works, as he could be cutting closer to large gravitational masses, thus shortening the distance and thus if traveling at the same hyperspace speed, is faster.

time is a human concept, it's simply a measurement

we used the earth as a reference

so in answer to your question, let's say you jumped in a space ship and zoomed off to a distant planet 1,000,000,000,000 light years away

Time would exist, if you wanted it to. You would have to create the measurement based on the characteristics of the new planet you landed on. You could say a year would be the time the planet circled it's sun. The only issue is that planet could circle it's sun in the same amount of time our planet circled our sun 100 times.

so 100 years on earth, would be 1 year in your measurements. You could use a different reference, say the new planets moon. or you could use our existing measurements, but that would be silly if you were on the other side of the galaxy. It's like saying aliens use our measurement of time, which would be highly unlikely.

does that make sense?

Groan.
No it doesn't. Time isn't a human concept, just because different people and/or ET uses different units, doesn't mean tome doesn't exist, there is absolutely a time dimension.

How would one access this dimension

There is something I need to do around 1994-1996 and it's rather urgent

You agree distance is a dimensions? How would you define that. Km, miles another unit?

Just because people use different units doesn't mean it's a human concept. It's just a human unit of something that exists.

You can very much calculate time dilation, we do every day, otherwise GPS amongst others wouldn't work.

let's talk about time machines

do you think it would be possible to travel in time (maybe within the next 50-60 years)

We are, time dilation, is the only working tome machine. You are just utterly wrong and clues. A human unit, in no way means it doesn't exist.
people are already time traveling albeit incredibly small numbers.


Just because you can't go back in time, in no way means it' isn't a dimension and physical.

You can always and have been able to travel forward in time, this actually has been proven, albeit in mere seconds not years. Backwards though, I can't see how that is possible. You are basically undoing something that is done. Like a bomb exploded and it goes backwards.

but the theory is possible that if you were to travel back, your timeline would continue, but you would now be part of a newly created and different reality.

It’s not a misuse of the term if it means he has amazing navigation skills and did the Kessel Run in a little as 12 parsecs (distance). I think the reference has he took a risky route via some blackholes.

Well, this is possible, but I reckon it was misused in the original film, and people have since tried to think up a legitimate meaning :p Particularly since in the context he uses it in the film is to back up the claims of the speed of his ship, not his navigational prowess ;)

More than likely, however in the extended universe they often talk about cutting distances off. Which makes sense if you fly everywhere at the same speed, then the distance becomes the important part. And going between a cluster of black holes, would shave lots of time off, compared to go around (again that happens in the extended universe)
