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
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
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.
he said go in the past not the future. im pretty sure time travel doesnt have to go one way buddy. open your mind to ANOTHER LEVEL non-nice individual.
Why couldn`t you have thought of the aeroplane 400 years earlier?!
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.
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.
oh and, if they do space travel, when they come back.. will they be considerably older or will the people back on earth be considerably older? or will it not affect? this time thing is confusing
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.
Gravity bends space. It also bends time. Time is a physical thing.
*sighs* NO. You can only go as far back as when the machine was first turned on. Do we have a time machine yet? No. So this question is moot.
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
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.
Answer: None of the above. Wormholes don`t exist.
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.
But that would really ruin the interstellar travel part. Although if it ever happens, I dare someone to go back 6 million years.
Uhu? Got anything more trustworthy than the bible or Al Gore to support that? :P
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.
i want my 4:09 back
Oooh... pretty graphics...
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.
The last sentence on this video proves it. Just look at the economy.
Didnt einstein also say Time Travel is impossible?
Or did i just dream he did....
Backwards time travel on a unilinear plane is impossible.
And yes, I am a douche.
Sure, it could be gooey and sweet...but I`m more inclined to think we`re just going to get stung. BAD.
A theory isn`t proven. He did theorize it, but in no way did he PROVE it.
Oh, and I would love to travel back to 2007 or something. I miss it!
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
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.
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.
In fact, all time-travel back to the past would logically violate the laws of causality, so time travel to the past should be entirely impossible.
That`s a pretty big if though that makes me want to still say no to the original question :P
ROFL and LMAO, give that man a Golden Banana! I like that sense of humour you got there pantelisk.
That`s it, I`m freezing my head.
Actually yes, if we find a way to travel at 99% Light speed then we can travel forward in time. But we wont be able to travel back in time."
Still a big old NO to that happening any time soon.
NO IF YOU FREEZE ME BITCHES!
To me, this video is saying, "it`d be really cool if we could travel through a tunnel that bent time and distance". But that`s like me saying, "it`d be really cool if I could jump back in time by putting my finger in a pistachio". It just didn`t explain much....
you don`t need to waste your time (no pun intended) inventing a something that allowes you to travel 99% of C just to go forward in timeim doing it now watch me, look see. also see im making you do wasting it reading the comment also, ive allways wanted to try this.
Good News EveryoneI`ve invented a device that allows you to read what I`ve written in my voice
Actually yes, if we find a way to travel at 99% Light speed then we can travel forward in time. But we wont be able to travel back in time.
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
I dont have a clue what that is but yes, just like it.
just like the 4400
has anyone being in one??/
no i thought so
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.
