But travel to the future? Credit: Wikimedia Commons 1. Time travel via speed This is the easiest and most practical way to time travel into the far future — go really fast. And the closer you get to the speed of light, the more extreme the time-travel. Time travel via gravity The next method of time travel is also inspired by Einstein. Gravity can slow down time. Time travel via suspended animation Another way to time travel to the future may be to slow your perception of time by slowing down, or stopping, your bodily processes and then restarting them later.
Could humans ever do the same? How the television show Lost in Space envisioned the future. Time travel via wormholes General relativity also allows for the possibility for shortcuts through spacetime, known as wormholes, which might be able to bridge distances of a billion light years or more, or different points in time.
Time travel using light Another time travel idea, put forward by the American physicist Ron Mallet, is to use a rotating cylinder of light to twist spacetime.

Question: if your parents died before you were born, then how could you have been born to kill them in the first place?
There is also the paradox of the man with no past. Suddenly, an elderly man appears from nowhere and gives the youth the secret of building a time machine. The young man then becomes enormously rich playing the stock market, race tracks, and sporting events because he knows the future. Then, as an old man, he decides to make his final trip back to the past and give the secret of time travel to his youthful self.
Question: where did the idea of the time machine come from? There is also the paradox of the man who is own mother my apologies to Heinlein. Then disaster strikes. She almost dies giving birth to a baby girl, who is then mysteriously kidnapped. The doctors find that Jane is bleeding badly, but, oddly enough, has both sex organs.
Out of guilt, he kidnaps the baby girl and drops her off at the orphanage. Not surprisingly, time travel has always been considered impossible. After all, Newton believed that time was like an arrow; once fired, it soared in a straight, undeviating line. One second on the earth was one second on Mars. Clocks scattered throughout the universe beat at the same rate. A second possible answer is provided by recent results that go by the name chronology protection: One supposes that quantum gravity allows microscopic structures that violate causality, and one shows that the character of macroscopic matter forbids the existence of regions with macroscopically large time loops.
To create a time machine would require negative energy, and quantum mechanics appears to allow only extremely small regions of negative energy. And the forces needed to create an ordinary-sized region with time loops appear to be extremely large. Newsletter Get smart. Sign up for our email newsletter. Already a subscriber? Sign in.

As several respondents noted, we constantly travel through time--just forward, and all at the same rate.
But seriously, time travel is more than mere fantasy, as noted by Gary T. Horowitz, a professor of physics at the University of California at Santa Barbara: "Perhaps surprisingly, this turns out to be a subtle question. Get smart. Sign Up. No one has the right theory in my thinking.
Only a few things are wrong. It is universes with what we call different time, days and years we are traveling to and not time itself as it is a illusion. Their is no stop to how much we can do, or where we can go. No limit as such say. There is no God. No magical serpent or Garden of Eden ever existed. Basing a scientific theory on archaic stories does no one any good. You choose a hopeless eternity. I choose hope through the promise of salvation through Christ for those who believe.
You see, I have child in heaven. Thankfully, have a hopeful reality that I can embrace. There is a God. Our known universe is only 14 or so billion years old… is it mathematically possible that random molecules out of the Big Bang mixed in just the right way from to form a complex cellular organism… with DNA… and result in humans and such diversity of life forms?
Think about it. How is that remotely possible without a creator? You make it seem as tho the big bang happened, and we just popped into existence?
Genocide, Crusades, all the ethnic cleansing.. All In the name of God Almighty! Aliens are more believable than this shit, and theirs no proof they exist either.
And we, yes Bible bangers, this includes you, are destroying it like the bubonic plague. You have not had an encounter yet with God. Made thing possibly that no one could ever explain. BlissfullyInformed just told me his comment was all an April fools prank. He believes in Jesus and was just fooling. Time travel is very much possible just as you decided to come existence in this century meaning one can decide to be in another time zone. Un like your other reply, I understand what you mean. Each timeline or universe as some see it can easily be traveled to at will.
No different than traveling threw your time you want to visit. Science has proven a few things from the Bible is true.
God does exist. Christians are confused with time and what it says. For a example. God created the world, as science even belives it was God who created the big bang, yet the bang has happen itself creating the moon, planets and stars. Christians also fail to understand chapter 1 and 2 of gen.
Their also was different time than, as without the moon a full day is 6 hours. It would take 4 days back than to equal are 1 day. Time is lost and Christians are just confuse on that time.
That does not proof their is no God. Changing the past is impossible, because if we went back into the past, that means we were already there during the time you experienced it. And what is life? Life is the evolution of the impossible into the inevitable over an infinite amount of time.
The contradiction implies that the original premise is impossible. This is called proof by impossibility. Thus if some traveled back in time far enough to kill his grandfather, we have the contradiction and therefore it is impossible.
You could argue that he would be able to time travel, but not kill his grandfather. However almost anything a person does going back in time would cause the same contradiction, thererfore it is the traveling back in time that is impossible. Actually, it probably is possible to travel back in time, however to do so, you would also have to travel so far in space that you cannot see anything that happened before your current time due to the speed of light, because this to could affect the future.
The reason I am here is that, i really want to go back the day when our matriculation exam was just finished. Everything around me is peaceful and happy. Currently, I am living in dire situation. People are dying outside on the streets. Smokes everywhere.
Everything is in doom. Ah, yeah. I really miss my past. If you are reading this, you can judge me in anyways. I just want to live peacefully and happily. I entirely know what you say and how you feel, Robin. I am totally convinced that future is no promise to offer a better place to live.
World is becoming unnecessarily more complex and more horrible and more insecure. Therefore, travelling back in time to a point where things were still far away from such ordeals is what I aspire.
But I think if it is possible to travel back in time without the possibility of carrying our lived experiences with us, it will be useless as we will be repeating the same mistakes over and over again. That is, becoming younger again in a physical regression as I said this would be a torture without having learned from all these later years? Or appearing at our desired times in our present physique and age? I believe the most ideal one would be if we appeared at our desired point in time at the same age that we were at that point of time with a good feeling of our later lived experiences.
Mam all u need to do is just run faster as much as u can or visit the black hole because in both condition time just slow it down …. Time travel is simple. If you do happen to travel to the past you create a new time line not affecting the time line you left.
In essence you going to the past is now your future. Even if you were able to return you may never know if you remained in your time-line or created a new one. So even if you changed something in your travels it would happen in the future not the past. You can only be in the time you are already in. General relativity allows time travel into the future. You need a space ship that can travel extremely fast though, approaching the speed of light, or you need to get close to a supermassive black hole.
It is travel into the past that there is no known practical way to do, and is probably impossible. So what happens when we Die? Where do we go? I want to go back in time so I can meet my childhood friends…. At what point, when a person says they are from the future, do we stop throwing them in the funny farm and actually start listening??
If it were so, we could glimpse blueprints of the future that we could bring back to the present and build before they were invented. My personal. I would love it if I had a real life time machine here with me now which could take me to anytime I want, the past, present or future. If I had a time machine here with me now, I would go to the past in September when I was born and give myself to another family that is actually rich and not this horrible family that I have now.
Wormholes are unpredictable, until warp speed for spaceships are a thing, it is not possible for the space ships to achieve time travel, unless they want to enter a black hole, which I would not recommend.
Yes it would be awkward to raise yourself. Basically you would have two memories one of the former timeline and one of the current different timeline. And that my friend is absolutely what you do not or would not know. To change the ingredients of a past life only changes the flavour you have in this life, it does not make you happier. No, travel to the future is not possible. Like, future is unpredictable and always have been so give up on that field.
Depends if it is the Governments they done it since the 80s , or if it was a Accidental travel, or a simple us creating our own machine. Either way, one can easily find storys, and other evidence with a good research. I have a website that shows the effects of change cause by time travel. They are out their done by the government since the 80s but the future is open with time travel told its open since so they travel back much.
Create a closed loop circuit around a full metal structure, hermetically seal it and bring O2, Use two tesla coils to create north and south poles.
Artificial Magneto sphere. Make sure to pain the outside in lead to prevent any cosmic rays from penetrating the materials on the inside. Pressurized Mercury, and Tesla Turbine. Then Move x faster than light depending on the charged field, Friction will be added to the electric field instead of the craft allowing the G-forces not to crush you inside.
The field will take the pressures of outer space, The temperature of space will allow for super conductivity of the structure. Eventually you will arrive in the future, if you stay in one place. There are many different ways to make wormholes, but the curvature of space is really hard to calculate to send a machine far out to the end and create a link with the machine that wants to travel there. And leaving one behind to get back.
Human Time is recorded in the magnetospere as a movie is record, ed on magnet VCR Tape or a song on a record. A VCR or record does not have to go light speed to retrieve the recorded info. All of life is recorded in 3D by our Magnetosphere. My Analogy is imagine a VCR tape cartridge being the earth, imagine life on earth being the movie but in 3D with out adom made tape, imagine Rotation and Revolution of Earth being the VCR putting all in to motion- playing.
By the way long before life on earth, he built the original 7 wonders of world Pyramids to Pump the Seven gasses into the atmosphere of this planet found in the goldilocks zone, so Life can live on it, and that life of all types is his technological cyborgs that grow and multiply on earth also he seeded it with plant, trees, sea creature and things that fly,. Anyway that above is how time is recorded.
Until recently, I thought my neighbor was a crackpot until he actually invented a time machine.
