TIME TRAVEL HURTS MY BRAIN

Ive had LONG discussions about it, and i just got bored of it.

Say

you go back in time and kill ur parents

so then you would never be born, right?

but if you werent ever born, how could you go back in time to kill then!

A man who changes his opinion is a man who knows when he is wrong. It's not a proverb, just something I say to myself. I like to be right, so when I know I'm wrong, I change my opinion of the matter to make sure I'm still right.

As far as time travel goes, you could look at it from a physics point of view. Some see time as an extremely long line, others see time as a infinite loop, and still others see it more multidimensional(whether 2 or 3 or more). The idea of time travel would require you to remove yourself from the current point on the line or plane and place yourself on another point on that line or plane.

To remove yourself from this point would mean a loss of mass. The atomic and subatomic particles that make you up have existed through out time. These will be loss. The space that the mass of your body filled will be replaced by a vacuum the moment you've left this point in time. I'm not too sure of the reaction to the loss of mass. It could be minute or catastrophic(my opinion is minute). The same questions could be asked about the arrival at another point in time. The would be a sudden gain in mass. If you're lucky enough to arrive in another point in time in air and not in a mountain side or building wall, what happens to the air that is filling the volume your body will suddenly be standing in.

With the idea of a person traveling dangers seem to be everywhere. If you could ever be transported, who's to say it'll also transport your clothes that are on you or even the air that was in your lungs. These things are merely trivial considering the actual concept of time travel is more important than the safety of the traveler. If it were to ever get that far, I'm sure travel would be done in a vessel with complete life support instead of only transporting the flesh.

Time travel is for fantasies, where a magic spell takes care of everything. To know that you could change your history and that your future is already created are things I'd rather not think about.

I think time travel is not possible.. I do think that you can "see into the future" sorta thing. And I do believe in like phyic(sp?) powers. I know they've done tests on these things, but if you had weird mental powers would you really let scientists do experiments on you? I mean seriosuly, the people that claimed they could, are probably the ones with mental issues.

Bubbles shuddup all you are pointing out is ONE of the several postulates proposed by scientists throughout the years, we sadly have never beenable to prove any of them The only time we have come even close to time travel is by Eientiens theory of relaitivity and thats it. We can time travel but the only thing thats stopping us the 'theory of everything' we just cant combine gravity and quantum physics into one equation that would explain the nature of atoms and the only theory that is proposed right now is the string theory which is nothign but bullshit I wanna travell back in time but thats impossible, trvaveling in the future is quite possible (well not in the near future)

Yea your quite right. I was endorsing A theory and presentism, although I realized that modern physics does not quite look at the world this way, I had not looked at their views critically. Plus its perfectly intelligible for me to think about the world that way in my day to day life.

A theory looks at the world as having 3 dimesions of space + time. Its more modern to view time as a dimension rather then some extra thing. So, now I'm more aware the the differing views, and I suppose that physics is likely the best bet, but that still leaves me quite confused as to what sense the present and the past coexist.

That video was too pop-sci/phl for my liking.

You do know that scientists also believe that space is not just space or vacuum....that its another entity

There is either mass or there is vacuum. What else is there?

The theory of relativity suggests that space is curved....if its was just nothing...why wud it bend?

Oh yeah...dark matter.

Conceptually what is dark matter? Some explain it as incredibly dense mass, others say it has no mass.

I just see it as a wild card for whatever the writer wants it to be.

^^^
The astronomer Dennis Sciama, for example, writes that it is misleading to talk of non-Euclidean space as "curved". But his point is perfectly general, and does not apply only to non-Euclidean space, for it is, in a way, just as misleading to describe Euclidean space as "flat". I will bracket certain phrases in quoting him, so as to make his point more general. In this instance, bracketing indicates not my insertions, but rather my suggested deletions from the original: "We can easily understand what it means to say that a two-dimensional surface is curved, because we can see this surface lying in three-dimensional [Euclidean] space, and the meaning of the word 'curvature' is quite obvious. But when this same name 'curvature' is also given to a three-dimensional [non-Euclidean] space (footnote: let alone four-dimensional space-time!) it becomes rather misleading. ... All that is meant by the curvature of space, then, is that gravitation affects the motion of bodies" - Norman Swartz

^^no and ^no.

Oh my God I have not taken a physics class yet, but one thing I know is that the last 3 posts above Eros' post are so wrong. Please read the link above
