Okay, so all we need to do is find a wormhole (even pluto way too far away to be reached by a human, so now think about the distance to a hypothetical phenomenon even rarer than stars) or make a wormhole (work out how to bend and alter the very fabric of reality in a controlled way).

suprise123, if I could hypothetically travel back in time, theory says that I wouldn`t be able to alter the past as the past had already been determined by what I did when I was there, even if I did it before I was born. Perhaps someone needs to rephrase that in a way that makes more sense

And Dragonlord, though the evidence is strong enough for most strictly speaking black holes aren`t observable themselves, but their effects have been observed. Seeing as they`re just big empty patches from which no light leaves, it`s impossible to ever see one, but we can see that light does seem to curve presumably due to some really really heavy object. But we can`t prove that this is a singularity (i.e. black hole

I personally think that we should NOT time travel, because it could mess up our whole world, and people who made differences could not have even been born...

"Science is observable, repeatable, measurable. There has never been any of these phenomenon observed [wormholes, black holes, stargates antimatter, and magic wands], let alone measured or repeated. So until someone actuall sees one, I continue to believe in the principles of Science."

Black holes (or at least objects that are exceedingly similar to the result that a theoretical singularity would produce) are observable, and have been for decades. Antimatter is also a well-known phenomena that has been measured both in labs and in the accretion discs of aforementioned black holes.

Wormholes are still hypothetical in that they are math based, and that the very few experiments done to give evidence to their existence, though those experiments have checked out.

Stargates are from a rather dull sci-fi series, and nobody claims that they are science. You`re building a straw-man argument, and a poor one at that.

Lionhart, you clearly have no concept of what science can

Time travel is impossible, since it would lead to algorithms to easily solve NP-hard problems.

ZOMG 37!?! GTFO.
So what?

The Phoenix probe that landed on Mars in May 08 had been travelling for almost 300 days, and had travelled over 400 million miles (400 million miles. 400 million. 400. 4.), and it was landed practically bang on target. That would be like me throwing a dart from here (Scotland) and pinning a fly to the wall in your house (Australia).

Voyager 1, the furthest man-made object from us, is now over 10 billion miles away from the Sun.

Why the hell would we ever need to send people out of orbit, when we can get probes to do it for us?

And black holes ARE observable. You look at the interactions of the objects around it. You don`t need a Polaroid of an electron to know that it`s there.


Again, you clearly don`t know what you`re talking about.

How can matter time travel if it can`t be in two places at once? We are matter. We go through time and the atoms in my body in 2009 are by year 3000 scattered all over the place. I go to 3000 step out and then what happens? The atom that was in my fingernail today is on a beach in Bermuda in the year 3000. This eliminates possibility of time travel.

Who are you to say what is possible and what isn`t? Did you create the universe? Do you know what created the universe? You do realize humans know extremely little, if anything at all.. right? Every single human, in all reality, are complete idiots. It`s comments like that that make me depressed.. People think they have everything figured out, when they have no idea, and will never have a clue.

"ooohhh. so fold the paper in HALF, and it all makes sense... poppycosh."

Well imagine a creature living in two dimensions, on the paper. When you fold the paper a gateway from one side of the paper to the other is created, making the distance short instead of long. The general idea is that a dimension can be folded from the dimension above. So basically our third dimension could be folded from the fourth, much like the second dimension is folded in the third with the paper example.

What future? Wake up. No-one has been out of Earth`s orbit in 37 years. 37 years. 37. We got to space, we discovered it was so big we could never go anywhere. Lots of people talk about wormholes, black holes, stargates antimatter, and magic wands because they can`t accept the simple reality that we are earthbound, forever. Science is observable, repeatable, measurable. There has never been any of these phenomenon observed, let alone measured or repeated. So until someone actuall sees one, I continue to believe in the principles of Science.

Ari: no one knows how to practically open a wormhole i think, but no laws of physics today prevent them. That might change, or it might not. I think that if we indeed do manage to attain technology of this kind we are talking about thousands of years of development, it`s not happening tomorrow, next week or the next century.

It`s not time travel in the way most ppl think. U don`t actually move backwards. U move slower. Time dilatation - the closer to light speed, time flows slower for you in regard to ppl who stay "still". Traveling faster than light (it`s a theory that some scientists approve) U don`t get younger, nor do U land before.
(numbers taken out of the blue)
F.eg.
traveling 1,5*LightSpeed a day for U is a month for the earth
traveling 2*LS a day 4 U is a year for the earth
and so on...

I find this title inaccurate. U don`t time travel. It`s instant travel. As for wormholes - I wouldn`t be surprised if black holes are a wormhole. PPL think there are white holes (BS negation) - we can`t find them though. Maybe cauze we think they R stars? (they burst light and energy @ the same rate BS suck them in).

IMO the question is:
When U time travel a year passes 4 U in a month. U age faster.
On the other hand - when U travel near light speed aging process slo(...)ws down/i

Ok, I don`t know a thing about science...but even if these wormholes can transport you to a place we actually wouldn`t be able to go to...where are these wormholes?
would we be able to make one ourselves? how could you be sure where and when you end up?
how do they know something can actually travel through them? and how would you come back? do these tunnnels stay open for a long time?
hm...i probably won`t live long enough to see that happening anyways.

Lionhart, you don`t know what you`re talking about. Leave the physics to the physicists.

It really pisses me off when people act like this towards science. They enjoy the benefits of all their past work while dismissing all the theory that lays the foundations for their future work, and they ACTUALLY THINK that they know more than someone who has dedicated their life to studying the topic.

So I`ll say again: You don`t know what you`re talking about, Lionhart. This guy does. Pipe down.

The thing about time travel is disbelief. Even if you DO come up with a way to do it and travel to the past, it`s virtually impossible to convince anyone that you have, in fact done so. Just ask
John Titor. Most people think it`s BS. How do we know it`s not true? We can`t know for sure, until we actually come up with the method and build a working time machine... and even then, most people won`t believe it`s true and that it`s just rumor or a made-up story.

And as for humanity not having much time left. We are a virus. We multiply without reason, take over everything we can and continue to expand. We are extremely resiliant to things that should have wiped us out such as disease, natural disasters and even each other. We`ll last a very long time in one form or another.

There`s the theory that until we create a wormhole, nobody can time travel, and we can only travel to other times/places where people have created wormholes, so then we can only go into the future.

But that would really ruin the interstellar travel part. Although if it ever happens, I dare someone to go back 6 million years.

Really if we look at humanity and what we`ve achieved in the last hundred years and knowing that the rate of which scientific discoveries is accelerating all the time, I`d wager that humanity is still in it`s infancy, technology wise. Why would humanity just disappear? What would bring this doom?

Well it seems to me that humanity would probably master optics way before we master time travel. So who knows, maybe there are time travelers all around us, that we simply don`t know about? I mean, we already have meta-materials that bend light. Besides, how do you know that some random guy on the street isn`t actually from the future? Can`t be that hard to blend in.

Also from what i`ve read and heard there is nothing in modern physics prohibiting timetravel. Actually i think it was Hawking that claimed it to be impossible, then set a prize for whoever could prove it impossible and nobody managed to do it.

it takes ALOT of enegry to reach the speed of light. cerns LHC only gets those particles to 99.999% of the speed of light and those are verry small particles, but they still have mass but as our knowledge progresses there is no limit to what we can do. in a few short years.(less than 200) we went from telegraph to cell phones but as for time travel goes we can (right now) move ahead in time that is no big deal were moving ahead right now the tricky part is to go back in time. once i figure out how to do that ill post it. the human race can do anything we dream of God gave us that ability.

No, he`s the idiot responsible for all this crap in the first place, he said the speed of light is impossible and if you could break it, you WOULD time travel. The fact that we`ve discovered particles like Quarks that travel faster than light seems lost on scientists who still seem to believe we can go back to yesterday. Time isn`t a physical dimension, its a convenient phrase to explain something that happened then not now. You may as well talk about traveling through the dimension of purple.

according to QI the other day,it is impossible to time travel back to a time where time travel is not yet possible (or something to that effect). for example having a telephone is useless if nobody else has a telephone.

also, apparently the LHC in switzerland may in some way make it possible for people to travel back to our time. i think it was to do with the whole wormhole malarky. bah

That is, of course, assuming that time is indeed causal videogamer. From our perspective it seems so, but yet with our limited knowledge it is hard to claim it as fact.

Sub atomic particles seem to break from causal bounds by being created and destroyed instantly. One could claim the existence of time quantum particle that operates under the same premise.

actually you only need to approach the speed of light to time travel

Yes and No. All you would be doing is watching the light that came from our earth. You wouldn`t actually be traveling back in time because that`s just impossible. You also wouldn`t be able to influence the past because it`s only light you are seeing. Luckily for us, because of that time space disruptions like in movies are impossible. seeing the past might happen some day, but is unlikely. It would be really usefull though.

It`s postulated that wormholes already do exist, and we could possibly create them at will with in the very near future.

The problem with these wormholes is that they do not stay open. The lifetime is probably around the Planck time, so obviously they are of no use to us.

We learned that an exotic energy source was required to keep the wormhole from collapsing and thus allow for traveling. Some theorists claim that what has become known as dark energy could hold open a wormhole. If its true that is good, because models show ~ 70% of the energy/matter in the universe is dark energy.

One problem, it is completely undetectable from a direct observation stand point. Theorists do have a strong grasp of dark matter, but are completely lost on dark energy.

Until more work is done into direct observations of this exotic energy, the world doesn`t have to worry about wormhole traveling. That was mighty long-winded just to reach that conclusion. :-D

How to Time Travel 101:

Step 1. Grow a T.A.R.D.I.S

Step 2. Bang on various knobs with a rubber mallet, pull a multitude of lever, and smash a plethora of different buttons in your newly grown T.A.R.D.I.S.

Step 3. Say the word "Fantastic!" and/or "Brilliant!" as you come to a teeth chattering halt that lands you on your ass.

You have now successfully time-traveled.
