Is Time Travel Possible?
My simple Answer is Yes, Shocked!. According to my findings time travel is possible in some cases. I know you are thinking that how it's possible and why then we had not worked on it and build a Time machine.
Wait wait, all your Doubts will be Clear in Upcoming articles or you say blog.
Only you need is to share my blog/Article as much as you can. link given below
More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together. Einstein also said our universe has a speed limit: nothing can travel faster than the speed of light (186,000 miles per second)
What does this mean for time travel?
As a part of Einstein's theory, Einstein re-envisioned space itself. He coined the phrase "spacetime," fusing the three dimensions of space and one dimension of time into a single term. Instead of treating space as a flat and rigid place that holds all the objects in the universe, Einstein though of it as curved and malleable, able to form gravitational dips around masses that pull other objects in, just as a bowling ball placed in the centre of a trampoline would cause any smaller object placed on the trampoline to slide towards the centre.
Well, according to this theory, the faster you travel, the slower you experience time. Scientists have done some experiments to show that is true.
For example, there was an experiment that used two clocks st to the exact same time. One clock stayed on Earth,while the other flew in an aeroplane (going in the same direction Eart rotates).
After the aeroplane flew around the world, scientists compared the two clocks. The clock on the fast-moving aeroplane was traveling slightly slower in time than 1 second per second
Here We go
Basically Time Travel actually the concept of movement between certain points in time by an object or a human, typically by using a device Time Machine it's all will be possible it's a hypothetical machine commonly known as Time Machine.
Time Traveling is a concept in philosophy and fiction, particularly science and space fiction.
Can we use time travel in everyday life?
We can't use a time machine to travel hundreds of years into the past or future.
That kind of time travel only happens in books and movies. But the math of time travel does affect the things we used everyday.
For example, we use GPS satallites to help us figure out how to get to new places.
GPS satellites orbit around Earth very quickly at about 8,700 miles (14,000Km) / hrs. This slows down GPS satallite clocks by a small fraction of a second.
Traveling back in time is theoretically possible in certain relativity space time geometrics that permit traveling faster than the speed of light can travel you in time, such as cosmic strings, Alcubierre drives and traversable wormholes.
The theory of General relativity by sir Albert Einstein does suggest a scientific basis for the possibility of Traveling back in Time in some of the unusual scenarios.
Now I am not not saying that we will definitely can go in Past but we are just discussing possibilities of happening.
Although the arguments from semiclassical gravity suggests that when Quantum effects are incorporated into general Relativity, but this loop holes can be closed.
These semiclassical arguments led Stephen Hawking to formulate the chronology protection conjecture, suggesting that the fundamental laws of nature prevent time travel, but physicists cannot come to a definite judgement on the issue without a theory of quantum gravity to join quantum mechanics and general relativity into a completely unified theory.
Althought many people are fascinated by the idea of changing the past or seeing the future before it's due, no person has ever demonstrated the kind of back-and-fourth travel seen in science fiction, or proposed a method of sending a person through significant periods of time that wouldn't destroy them on the way. And, as physicist Stephen hawking pointed out in his book "Black Holes and baby Universe" 9bantam, 19940, "the best evidence we have that time travel is not possible, and never will be, is that we have not been invaded by hordes of to from the future."
The closer an object gets to the centre of the dip, the faster it accelerates. The centre of the earth's gravitational dip is located at the Earth's core, where gravitational acceleration is stringest.
A more dramatic example of time dilation can be seen in the movie Interstellar when Matthew McConaughey and his crew land on a planet with an extreme gravitational field caused by a nearby blackhole. because of the black hole' intense gravitational influence, time slows dramatically for the crew returns to Earth, Matthew McConaughey's daughter is an old woman while he appears to be the same age as when he left.
