Is going back in time really possible? If so, would we have the resources to do it..say 100 years from now?

Answer 1

I don't think so because technology is way beyond time-travelling...

Answer 2

Yes it is possible in an indirect way, and not by sitting on planet earth.

Say, the light which is reaching us (earth) NOW from distant stars of the galaxies have started from it millions of years ago.

Suppose life existed on those stars. Then if we had some mean to convert those images then we'd be looking millions years back than what it is now TODAY. Or if we could travel faster than light to reach some other point in the universe and look at earth then we would be able to see what happened long ago on earth. That would be going back into past!

Also, take for instance, that a particular star may not be existing RIGHT NOW, even then we would be receiving its light for millions of years from now. We would look its past and no present.

The imagery of earth reaching to some far away planet NOW, consider as if some kind of telecasting, may be that is showing, say the biblical times.

Other than this traveling into past is not possible.

Answer 3

We are all time travelers. We travel into the future. In 24 hrs we will all have traveled 24 hours into the future.

My belief is that time travel to the past is impossible. Time travel to the past based on the belief that that some kind of image is left as we move forward like images on move films. Sorry but I can not believe that any more than I can believe in ghosts. The best that would still be impossible is to move at a speed so fast that time “seems” to stop. But we will never be able to move that fast. We don’t have to even go to space to slow down time. Those that live on the highest mountains that support life live in a different time (speed) than those at sea level. That is a fact. So if you want to slow down your ageing move to the highest mountains. In other word time is relative to the speed of the object that is moving. Remember the space traveler that leave earth then when the traveler return many years later those on earth have aged much more than the space traveler did. Time had slowed down relative to space traveler.

Steven Hawkins, as many others, in his book “a brief history of time“ believed that “if” the universe collapse that time would reverse. If a cup fell and broke. When the universe collapsed the cup would reassemble itself like watching a movie in reverse. Which is what I think is were some of these misconceptions come from. When I checked his web sit in 2001 he had changed his view and now believes that time will still travel forward “if” the universe were to collapse. Which is the position I took from the beginning (I made a note in the book back in the 90’s about it and gave the book to a friend. As far as I know he still has it).

Traveling into the past is more fantasy, fiction and dreams than reality.

Answer 4

Okay, so you travel back in time, if time is linear, today you invent your time machine, you get in and you attempt to travle back to last Saturday, you would be then suffering from a condition known to most medical people as death, as you had not taken into account one simple fact, the Earth itself has moved, you would appear in the point of space where the Earth was one week ago today, but you would still be in the same position as you are now.

So you would also need to travel top the point in space where the Earth was one week ago, therefore in order to travel in time you need also the ability to travel in space, the further back you want to go, the further in space you need to travel.

As we are not yet close to the tech that would take us in our own time out into space, currently it would still take us eleven years to get to Pluto, then the conquest of time is a non starter, as for another 100 years time, anything is possible in that time frame, look back 100 years and see what has been achieved in that period.

Daydreaming around the idea that people in the future have time-travel and are using it, this may be a more rational explanation for UFOs, alien races with supertechnology would not have to hide, people from the future studying the past would.

Answer 5

YES YES YES

there are NO LAWS that say time travel could not be possible.

Einstein proved it to be possible in his theory of relativity.

the faster you go the more time slows down.

even satillites around the world display this idea. many of their clocks are behind because they travel faster than we do. they constantly have to be altered to match time on earth.

apperently all you really need is some ring laser array, creating a circle, or oscilatting spiral of light, .

as light travels the speed of light in a circle (with some added secret sauce, which will be announced shortly) it begins to warp space time, I imagine time can be "stopped", but Dr Ronald Mallett claims he CAN go BACK in time.

well, not HIM but a quantum particle.
he claims the FUTURE HIM can send information embedded in a particle BACK to the HIM in the PAST.

he also stated that time travel within the machine can only work for the time period in which the machine is turned on.

good luck Doc, Even if your wrong, I admire that you have the courage to look crazy.

seems he only need 250 thousand $$ to build his working protoype, BUT he already has the equations and the design

oh, no time paradox, like what if you go back in time and kill your mom? won't you die too since she can never give birth to you?
this doesn't happen. If we look at string theory it claims there infinite different "dimensions" of time, all possible realities existing at once.

once your transported in time, a new reality is created, uneffecting the others, or the others uneffecting you.

**** Avondrow's idea of where are the travelers shows this idea too.

Answer 6

Time travel is both possible and impossible. It is possible only if you are able to travel at a speed much greater than the speed of light. Now it is impossible because in order to travel at a speed above the speed of light you need to physically escape gravity, not the kind of floating in zero-gravity situations.

As for going back in time again you need to overcome the gravitational pull.

Answer 7

They say theoretically it's possible.

But only to the point at which time travel was made possible and not before it.

Kinda like a phone call - You could only 'call' another person who had a telephone. ie you could only travel back to the time and place where the facilities to do so were created and not before then - Say the equipment need to time travel is created in 2050, you can't travel to 2049 or earlier.


If that makes any sense?

Answer 8

Black holes are the key for this because they are the oney things that have the needed power 2 ways to go there as well learn to control real black holes or make man made black holes and there a rule not gone over in this yet can one go sideways in time as well as back or forward when useing such power

Answer 9

Think about this: if backward time travel were possible, how come we haven't been visited by people from the future?

This is quite apart from the fact that the concept is logically and philosophically absurd.

Answer 10

how about staying stuck in time? my neighbor her hair, makeup and even apt is all in the 70's (she looks like she just woke up from a nap in 74 and nothings changed lol) she's leaving in her purple pacer,,,, I'm sure in 100 years will probably be able to do anything---being that are technology is surpassing are humanity anyway

Answer 11

There is only ONE way to make certain that time travel is a viable and useful possibility: simply see WHO patented the concept FIRST.
