Some Scientist belive that Time travel is possable but the only reason for our time line changing all the time is because when you go back something stops you from doing what you were going to do. Personaly i think thats bull.

My Theory is this, you go back in time and the exact nanosecond you go back you creat a new timeline not effecting your original one. Now lets say you kill hitler in 1921 or something drasticly effecting the course of events. Now you go forward intime to see the results of your action now lets say that you want to get back to your original timeline you would go back intime before you originaly came there thus creating another alternate time line were your original actions dont take place then you can go forward in time and be in a very similar timeline to your original.

so what do you think

~Thanato

so in your theory of time travel when you go back of forward in time does that create another living entity of yourself? if you get what im saying

i think that has been a lot of peoples theories for a very long time, and i also dont believe in creating an alternate universe/timeline/whatever


time travel is theoretically possible, but will never happen because you would have to travel past the speed of light, and as we all know faster than light travel is impossible, shoot light travel is impossible for humans

the only kind of time travel, if you want to call it that, would be time travel to the future and the only way it would be possible is to go into outer space and to travel very fast for a very long time around earths orbit, upon your return to earth you would have aged slower than everyone else on earth thus giving the appearance of "time travel" into the future


seeking/time travel lesson for the day

Faster then light travil is impossable, for right now but who knows what the future holds. If i recall no major scientist who deals or dealed with it said it was impossable to travil faster then light.

I also have another theory that each moment is relived kinda like a time loop.

~Thanato

whos to say that someone withaccess to time travel isnt going in the past and changing things all the time

we wouldnt know

well, thats true but i belive my theory makes more sence.

Also yes you would theoreticly be making a copy of your self, which might hace some sort of effects on you or it might not.

~Thanato

no see, speed of light travel isnt even possible, due to E=MC^2

the faster you go, the heavier you get, the heavier you get the more fuel you will need to accelerate, more fuel also adds more weight, and more weight means more fuel, its a paradox that is impossible to get around, light and gravity can travel at C only due to the fact that they are both massless, meaning they cant get heavier as they speed up

and if we cant even reach the speed of light, how then can we exceed it? impossible

Travelling to the past would be thru some kind of wormhole in that case.
Parallel universes is discussed by scientist all over the world nowdays.
Specially to solve the string theory and gravity problems that occur when calculating this.
So you may be right.
I dislike when someone says the word "fact" or "impossible" in this forum because we all know that it all is theories and NO ONE can know anything for a fact.
Everything is only theories.
Everything from Big bang and string to size of the universe and beyond.
Thats a fact.
Please be critic when listening to "experts" no mather how well educated.

Maybe timetravel does change history and future, but we're not aware of it when we get back to our original time. That'd explain a lot.

But I actually don't think man is capable of travelling through time. It's a dimension, like space consists of 3 dimensions, I believe it is common knowledge time is the 4th dimension. Since there is no escaping the space-dimensions, we will also never escape the time-dimension. Because of our bodies, our matter. It's in the way. When we're no longer consisting of matter, we'll be free to go anywhere.

There is a theory that gravity goes thru dimensions or paralell universes.. I dont remember exactly how they put it in a text by a scientinst I read.

listen, it is IMPOSSIBLE to travel at light speed, there is no possible way anything with mass can travel at light speed, it just cant be done, i allready explained it in my previous post

also, worm holes can not allow you to travel back into time, only into the future, a worm hole is only a short cut through time-space, just like if you and your friend were to walk around the block, and you decided to cut through someones back yard, that cutting through the backyard would represent what a worm hole does

and i read about the theory that gravity can escape our dimension and go into others as well, and it is quite plausible, it does make sense when thinking about it, it would explain why gravity is so "weak"

I'd have to agree with seeking on the it's impossible to travel at or past the speed of light. It would take an infinite amount of energy to do so because of how heavy the object gets with it's velocity. I believe it may be possible to travel at near light speeds in the future. Which may mean we will be able to time travel that way but there are still too many paradoxes to know for sure. I also think we don't have enough information about wormholes to know for sure which way they run, whether it be in time or to another existing parallel universe. From the known information of today, if you were able to stabilize a wormhole it would be a one way trip and you wouldn't know where you would end up at.

I don't believe you are able to travel back in time and create an alternate reality in the same universe. I tend to lean more towards the theory of the wave function and parallel universes. An object exists in all states at once until an outside force observes it and collapses it's wave and then it takes on it's final form. Therefore I think it's more likely that the alternate realities (if there are any) exist in different universes.

Your theory sounds good but what happens to the other timelines that you create by going back?

Just venting my thoughs.....

I've always had a question about the speed of light, maybe one of you can enlighten me (no pun intended).

If the following three statements are true:

1. Light is an electromagnetic wave.
2. Waves travel in a series of peaks and troughs.
3. A straight line is used to measure the distance (and hence speed) travelled.

wouldn't that indicate that an individual photon is snaking it's way through the universe at faster than the speed of light? Isn't that, err, impossible?

Just a thought...

light can be classified as a wave or a photon depending on the circumstances

Well, unless you consider Einstein a major scientist!!!

what about an antigravity thing. or if we figure out a way to make an objects mass really low like light photons and waves? i was reading about some scientists that were working on this type of stuff.

maybe perhaps we can create a machine that can travel near light speed, but a human will never achieve this, as we cant make our mass any less than what it is now

but what if we make a craft that can do this while we were inside it? would we just stay where we are at take off while the machine high tails it outa there?

In a hundred years humans will look back at theories and what many of the so called "experts" had today and laugh at some of these theories at the same way we laugh at theories that was accepted 50-100 years ago today.
still do not like stubborn people that only thinks in narrow paths.
Lucky everyone isn't locked down to a single theory but tries to find possibilities and are open for different points of view instead of brushing them off right away.
We wouldn't go anywhere if everyone was like that. Remember that is the radical ideas that gets the science forward and not the people that says "impossible".

truer words couldnt have been spoken kaj.

Einstine never said traveling faster then light is impossable, he said that it would be difficult. Also what happend to all thouse people who said that traveling faster then the speed of sound was impossable, they were scientists looks like we proved them wrong eh, so light is just the next berrier and im sure somewere in this vast universe that something travels faster then light.

~Thanato

99% of the universe we think we know is invisible, dark materia and so on, and things that does not follow the known laws of physics.
Stephen Hawkings and his co workers supports this theory.

For example:
In a our and other solar systems the planets closest to the sun moves faster around the sun (a year is shorter) than the planets further out...
But spiral galaxies does not follow this rule...
The stars near the center spins around in the same speed as the stars far at the edge of the galaxy.
Why??? Hawkings theory is that the gravity of invisible materia holds it together.. in other words..there is not nearly enough visible stars that can hold it together this way so the galaxy must be 90% of invisible dark powerful materia that makes this possible.
OR some other unknown phenomena.

Not about time travel, but anyway, explaining how little we know.
Do not tell me what is possible or impossible, because you don't know, and neither do I.
Theories, yes..... Facts, not yet.

It is the equations of 1905 relativity that prove the impossibility of traveling faster than the speed of light. Mass is divided by the square root of one minus C**2/V**2, if I remember correctly. Thus, going at the speed of light would mean dividing by zero. Didn't anyone ever tell you not to divide by zero? The particles in large accelerators are going very close to the speed of light, say 99.999999% of C, but as you add more nines, you just increase the mass, energy and longevity (time is transformed too) and decrease the length. This process is unending.

1905 relativity also shows us that time has to be an imaginary number, thus time is an imaginary dimension, and nothing can travel along an imaginary dimension. This is fortunate. That way, we don't accidentally disappear into the future or the past. In the physical world, past and future do not exist. It is always now, everywhere. Could 1905 relativity be mistaken? I don't think so. Accelerators wouldn't work if it were wrong. Nor would things like Muons live long enough to smash into our atmosphere as cosmic rays. 1905 relativity is the only theory of 20th C. physics that does not have cracked foundations. That is, it commits no mathematical or logical fallacy, as do all the other theories of the past Century. There is quite a bit about this in my book UFOs, PSI and Spiritual Evolution .

einstein is the one who proposed that the speed of light is the universes speed limit...you cant exceed the speed limit of the universe


now, how hard is it to understand that anything with mass will never be able to travel at light speed? the faster you go the heavier you become...this is known, and has been known for some time now...urgh!

im confused...i just seen this old post from you, Thanato, in a thread that was bumped today...





what caused the change in opinion?

yes it is a part of superstring theory.

What about the following:

Imagine a lightsource in some space, for instance our sun in the universe. One spaceship is moving towards it, travelling at half the speed of light [purely hypothetical]. Another ship is travelling away from it, also at half the speed of light. Considering the lights frequency, the light should be faint from the pov of the ship travelling away from it, and bright from the towards-travelling ship's pov. But it isn't... wouldn't. Would it?

How can light be subjective to the viewing individual? I fail to understand that.

I guess you guys would be surprised to know that there is both mathematical and empirical evidence that:

1. Time travel is possible
2. It involves supraluminal speeds


With one small, tinly little condition: It applies only to individual quanta.

Experiments have shown that photons (and electrons in a replicated study) "chose" in advance whether to behave as particle or a wave. This "in advance", the math suggests, means that a photon launched from a galaxy 10b ly away (and 10b y in past) "knew" you're going to measure it and it launched with the correct property, according to your measuring method. Since photons obviously can't "know", it is suggested that supraluminal and transdimensional information travel occurs from your measuring point up to the point where the photon was launched, regardless of distance, ie. the information about the photon being measured came back through time to the launching point and suggested proper behaviour.

Which is an illusion, an interpretation suggests.

Because, quanta apparently exhibit no properties UNTIL measured. So, our photon launched 10b years back came to our measuring point and "decided" to be a wave or a particle according to the measuring method we're using. If we're measuring it as a particle, it will be a particle. If we're measuring it as a wave, it will be a wave. If both, then it will, yes, exhibit both properties.

The experiment is known as Delayed 'Choice' Quantum Eraser.
