how is time travel possible?

Question

how is it possible to build a time machine to travel forward and back in time and how could it possibly work

Answer 1

Theoretically, since light is the only constant in the universe...if you were able to bend it somehow, it would cause a rip in the space time continuum. You could not, however, choose anytime or place to go to, as it would be completely random.

Ripples in space are shown when light is bent by high gravimetric forces, such as black holes. Worm holes are thought to be a rip in space, a portal to somewhere, maybe sometime, else. Space and time are thought to be like one. There are many theories.

By the way, you can always order one off the internet like Napoleon Dynamite did :-)

Answer 2

There is a theory on how to travel to the future.

It's something like if you travel at the speed of light somewhere, it'll only take you, say, 10 minutes. However, since the Earth is moving at a much slower speed and so 50 years could have passed during that time. When you get back to Earth, you've experienced a much less amount of time than the people on Earth.

Unfortunately, we can't travel at the speed of light yet.

Traveling back in time doesn't work and most likely won't work, unless we find some weird flaw in space and time...

Answer 3

My high school english teacher was in love with time travel theories.

He swore that it was possible to go through time if you do this...

Watch a clocks hands, the second hand preferably, or a ceiling fan would work too.

The closer the fan blade is to the center of the fan, the slower it moves. The edge of the blade farthest away from the center is obviously moving much faster than the edge close to the center.

build a large scale replica of this fan type device. get a motor to drive the spinning blades/arms as fast as you can. due to technology restrictions, theres no way we have any motor thats capable of making something go faster than the speed of light. BUT with this theory, the center of the fan device would be rotating at, lets say 500 mph, but the outer edge of the blades would be rotating many, many times faster than that. The longer the blade, the higher potential top speed it will have. Make it long enough, and it would eventually hit the light barrier. It is actually not too hard to understand.

does that kind of make sense? If i could draw a picture it would be alot easier to understand. Its 5am and i cant sleep so yeah.

Answer 4

it is possible to go foreward in time for example 50 years in 5 mins this is because as one approaches the speed of light time slows down and space as well as time curve around that object
the reason it is impossible to reach the speed of light is because that is like a 0 marker when you hit it time passes infinitely around you while none passes for you

backward time travel is impossible for many reasons that pertain to physics but id rather explain it logicly
if you went back in time and changed something you would never have gone back in time to change it in the first place and therefore it never changed
if you do manage to go back in time there are two theories as to what will happen
1. everything you do happened anyways and all of your actions play a part in what has already happened and most likely become a cause. through this the universe is once again stable and nothing changes
2. you will create an alternate timeline that runs under the fact that whatever you changed happened the way it did
i perfer to believe the 1st theory because the universe as a whole wants to stay ballanced and also because if you were to go back in time and create another timeline you would be creating an alternate universe and that energy has to come from somewhere

Answer 5

I can only answer that time machines is based on time management. If you can create the machine which can defeat the speed of light of the sun in one year and you can make it in one minute then you are 60 years more older if you are in time machine within 1 hour (60mins). If you want to travel back, you have to beat the opposite speed of light. Example: speed of light is 3000 (for example, not real). Your time machine speed is 3000000, then you can be older for the next minutes or perhaps second! However if you want travel back you should give it to another sign such -3000000 then you will be younger than now within a minute or even a second!

Hope this answer will be helpful for a bit, and please apologise me if there is any mistake or mastering the concepts wrongly.

Answer 6

I don't know how you can travel back in time but in order to travel forward you simply need to move with the speed of light.And then after traveling for 5 years you will see that it's been 50 years on Earth.

Answer 7

LET THE POWER OF MY ENCHANTED RING ENLIGHTEN YOU...The Cosmos is full of Wonder and Awe. But traveling faster than light (which is has been done on the atomic level), will not allow you to see the past. The measurement of Time is key here. Humans on earth measure time using the earth's rotation about its axis and the earth's rotation around the sun. If you are on a spaceship cable of flying at the speed of light what would be your time measurement? If you are using radiation cycles of cesium atoms (like people on earth), then the time elapses would be the same. The spaceship is covering 186,000 per second traveling 3 trillion miles into outer space and then 3 trillion miles back to earth would achieve this in one year. Space-time continuum is a fallacy.

Answer 8

You would have to build a machine that can travel faster than the speed of light (3x10^8 m/s). You can also read some stuff on string theory. It is too complex to post in this space, but i would recommend "Fabric of the Cosmos" by Brian Greene. He discusses this in some detail.

Answer 9

The phenomenon is not practically possible in the physical plane... But travel to the past has been possible by hypnosis whereby some hypnotists have found that their subjects recollected their past in this life and beyond - in their earlier life - and thus got rid of the fear of death... Some western hypnotists have documented these instances and released as books giving details... But the subject could travel to his past experiences and not the past of others, not connected to him /her in the earlier life...

Travel to the future is possible again, in the mental plane, by certain yogic practices... not astrological prediction type... Saints in the distant past have recorded the future (like the Revelations in the Bible) by actually visualising the events and the palm leaves in India containing such instances to come, alled the "Naadis", are well known ....

The story of HIndu deity Rama, who is said to have led a human life - as king of Ayodhya - lakhs of years ago (beyond the grand destruction and recovery of the planet..), was said to have been written up to his departure (to the heavens) by Saint Valmiki even while the king was still alive... He is said to have seen the events to come in the life of Rama that proved true...

What is interesting is the recent finding in the remote sensing imagery's that deep in the seed bed of Indian Ocean there is seen the remnants of a big rocky bridge connecting the mainland India and the Sri Lankan island - reminding Indians of the bridge said to have been built wth rocks by the legendary Rama several lakh years ago..

It may be difficult to believe for rationalists the distant past events revealed in historic /epic documents, since they could have been much distorted over the long chain of years... that too about the heros of religious epics... but they may be able to entertain even the impossible things like the Time Machine, if it comes from the science lobby...!

Answer 10

For example, search CERN (Centre Europeen pour la Research Nucleare). There is a machine for time travel.
Light energy can do that travel.
You can increase your speed as much as you want, until you become light energy.
The bad new is it is just a one way travel (once you become pure energy you will not be human again)
