TIME travel is possible and has already happened, according to several reputable physicists.
single way to reach time travel hooked on the future would be travelling at the tempo of daylight in room, as original theorized by Albert Einstein.
really Cosmonaut Sergei Kraaled strictly life in the prospect unpaid to his extensive epoch on the global Space position.
following expenditure approximately 804 days in breathing space at home back in soil 0.02 second in the potential gratitude to a procedure recognized because instance dilation.
below customary theories of time travel engineers would have to put together a legroom ship which could voyage at the alacrity of light (186,000 miles-per-SECOND), and beginning out into space.
Theoretical physicist and string theorist Brian Greene, of Columbia University, said: “You can build a spaceship, go out into space [and travel] near the speed of light, turn around and move to flipside.
“envision you go elsewhere for six months and you turn about and you come flipside for six months.”
even as you are travelling at the velocity of light, point in time stay slow family member to the citizens who be position still rear on Earth.
because a cause, you would be departing fast at the same time as your alarm clock would still be departing slow.
Prof Greene: “When you step out of your ship, you’re one year older but Earth has gone through many, many years.
“It can have gone through 10,000, 100,000 or a million years depending on how close to the speed of light you traveled.”
on the other hand, the simply problem is so as to a appliance travelling at such rate would require an “incredible” amount of energy, while the stress from the centrifugal force on the body would likely prove fatal.
bar there is a further reasonable way to take a trip even if time, along with some time ago again it involve going into on the outside freedom.
Einstein also theorized that if you be to position yourself on the perimeter of a black hole, point would get ahead of added unhurriedly.
Prof Greene explain in his full-size reflect video: “You hang not in [next to a black hole] for a while, you come back, get out of your ship and it will be any number of years into the future, whatever you want all depending on how close you got to the edge of the black hole and how long you hung out there.
“That is time travel to the future.”
But time travel has already happened.
