Is time travel possible? The short answer: yes, and you are doing it right now: plunge into the future at a staggering rate of one second per second. You're almost always moving through time at the same pace, whether you're watching the paint dry or wishing you had more time to visit an out-of-town friend.  

Time travel to the past is theoretically possible in some geometries of general relativity  that allow faster-than-light travel, such as cosmic strings, holes Passable worms and Alcubierre engines.  

Can we use time travel in daily life?  We cannot use a time machine to travel hundreds of years to the past or to the future. This kind of time travel only happens in books and movies. But the math of time travel affects the things we use every day.  

Yes, time travel is real. But that's not quite what you might have seen in the movies. Under certain conditions, time can be seen to pass at a  rate other than 1 second per second. And there are important reasons why we need to understand this true form of time travel.  

The way of Time Travel:

1. Time travel through speed :- 

This is the easiest and most convenient way to time travel to the distant future - go  fast.  

2. Time travel by gravity :-

The next method of time travel was also inspired by Einstein. According to his theory of general relativity, the stronger you feel the force of gravity, the slower time moves.  

For example, the closer you get  to the center of the Earth,  the more gravity increases. Time passes more slowly for your feet than it is for your head. At the speed of light, time slows down for you relative to the outside world.  

3. Time travel past suspended animation  :-

Another way to time travel into the future might be to slow down your perception of time by slowing down or stopping processes in your body and then restarting them later.  

Bacterial spores can live for millions of years in an active state of suspension, until the right conditions of temperature, humidity, and food begin their metabolism. Certain species of mammals, such as bears and squirrels, can slow down their metabolism during hibernation, greatly reducing the cellular requirements for food and oxygen.  

4. Time travel through the wormhole  :-

General relativity also allows for the possibility of shortcuts through space time, known as wormholes, that could potentially cover distances of a billion light years or more, or into periods of time. different points in time.  

5. Time travel through light  :-

Another idea of ​​time travel, put forward by  American physicist Ron Mallet, is to use a rotating cylinder of light to twist spacetime. Theoretically, anything that falls inside the swirling cylinder can be dragged through space and  time, like a bubble that spins over your coffee after you've swirled it around with a spoon.
