Stephen Hawking Time Travel Theory

Stephen Hawking Time Travel Theory

Time Travel, that is time travel, it sounds good to hear but the reason behind this is that the brain tricks the mind! All of us want to go back in time to improve the mistakes made by ourselves, and for future travel through time to know our future, but is it possible? Can time travel in that time?

If you are seen by the scientific person, then time travel is possible. If we are seen then we are travelling all the time. All of us are going out of the past and are continuously moving towards future towards future and this is called time travel. And the rate of travel in our time is 1 hour per hour! That is, we will take a 1 hour time interval to go 1 hour forward in the future! But can the time travel rate be faster than an hour per hour? That is, can we go ahead in the short intervals in the future? The answer is yes, we can travel thousands of years in a short time span!

By the way, time travel is possible by many theories, but in this post, we will only highlight light on one theory!

When Albert Einstein published the Theory of Relativity, the theory of relativity, based on the same theory, time travel started imagining! Prior to the publication of Einstein's Theory of Relativity theory, there was only one concept among people that the speed of time in the universe is the same everywhere that is on earth! He believed that the speed at which time is passing on the earth, in such a way, the time will be passed on this planet even on another planet! But Einstein gave a different definition of time by proving this concept of people wrong!

Albert Einstein told that the time and space are connected to each other! Which is called Space Time! Time is the 4th dimension i.e. the fourth dimension and the speed of time can be slowed or fastened! The time in the universe is running like a river, just like the speed of water gets accelerated somewhere in the river, then, in the same way, the time in the universe is running at different places at different speeds!

According to Einstein's equation of space-time given in Einstein's theory of relativity theory, time travel is possible. According to Einstein's space-time equation, if an object moves faster then the time will slow down and the speed of that object increases The time will slow down as you travel in a fast-moving train or aeroplane, then you have time for the outside world The expectation will be slowed and when you get out of that train or aeroplane after your visit, you will have reached in the future! However, due to the speed at which you will be able to reach a hundredth of a second in future in future! This difference of time is very modest, to realize this difference of time, your speed should be equal to the speed of light or up to 95%!

Stephen Hawking, who explains the concepts like Big Bang theory and black hole, imagined a railway track for the time travel that was made around the earth and the speed of the speed of the train running on that track would be equal to the speed of light! When the train runs at the speed of light on the tracks of the earth, the time will be slow for the passengers sitting in the train so slow that the life passing on the earth will be seen faster than it is so fast that the moment of the train is here Will change in Although the passengers sitting in the train would feel like the normal inside the train, the time inside the train would have been much slower than the outside world! When the train will stop after a week, according to the passengers sitting in the train, 65-year passes on Earth for a week's commute, and the travellers will find themselves in the future and the boys of those passengers will be elder than them!

According to Einstein's space-time equation, time travel is possible only in the future, that is, once in the future, you can not come back! Mean One-way Ticket to the Future!

Now here a question arises whether it is possible to make a movement running at the speed of light? According to our current technology, the answer may be frustrating! It is not possible to make such a train right now because according to Einstein's theory of relativity, if the speed of an object increases, its mass will also increase!

Let us suppose that we created a train which can run at the speed of light when the train runs at the speed of light then its mass will be infinite! And to run an infinite mass of the equation E = mc 2 given by Einstein, the endless energy will be required! So much energy is not even in our entire Galaxy if we fill the entire universe's energy in that train, then maybe the train runs at the speed of light! If we run that train up to 90 or 95% of the speed of light then perhaps we need the energy of our entire Galaxy in order to run that train at such a speed!

Now here a question arises that it is not possible to make a train running at the speed of light, then the imagination of time travel is eliminated! I do not believe there, besides this principle, there are many other theories by which time travel is possible!
