Actually time is created by humans and does not physically exist in this universe. We have to remember one thing. Our solar system is not even 0.00….1% of the universe. Based on Earth rotation to the Sun of our solar system, we are calculating the days. If yes, how can we change the whole universe state in terms of time by inventing a machine or calculation from not even 0.0….1% human technology. Still we are struggling to travel nearer to the speed of light. But we are telling ourselves that we can travel to the past and future by traveling beyond the speed of light. Because the state of the whole universe cannot be changed from a very very tiny place of the Universe. Let me tell you an example for that.
Let us assume that in 2041, I would invent a time machine or time travel mechanism and travel to come here in 2021 to give ideas for this article. While I am travelling, I may change my physical situations which can be accessed by time machine or mechanism. But I can’t change the whole universe's planet's positions. Now in 2021, Saturn is nearer to the Earth. But in 2041 it won’t be. If my time travel mechanism has the capability to travel the time to the past, It should have the capability of changing the location of the Staurn too. Not only Saturn, all universes, Solar Systems, Planets, Moons, Natural Elements, Solids, Human, Animal, Plants, Atoms, Cells and everything which existed in this universe. I don’t think that we can find out the mechanism or machine which has the capability to change all this physically according to destination time.
I have like these type of the examples to prove time travel is not possible. Then they say that we can freeze the time when we are travelling at the speed of light. Again there is the mistake of understanding the traveling of time with the traveling of the Photons. According to science, Light is travelling at the speed of 3,00,000 kmph. That means, a photon which is a light particle can travel at the speed of 3,00,000 kmph. In the future, if mankind finds a machine which can travel at the speed of light, the passengers of that machine definitely feel that the outside of the machine is freezed. So they definitely assume that time is frozen. But it is entirely wrong. Actually you are travelling along with photons with the speed of 3,00,000 kmph. So the same photon which is travelling with you from the starting to ending of the trip. It's similar to that if two trains travel at the same speed in parallel in the same direction, your eyes believe that illusion of that other train is freezing. The same illusion will happen if you are traveling at the speed of light.
The same illusion will also be applicable in the scenario of “man falling into the Black hole” concept. If a man falls into a black hole, the outside people can see him like he is frozen. Actually he is falling nearer the speed of light into the black hole. So his image is traveling to the opposite of the light direction at the same speed. So other humans who are watching him feel that he is frozen. After some time his image will fade due to he falled into the black hole.
So, really can’t we travel to the future or past? Physically yes. But virtually we can see the past from our present. Not by recording or anything. Actually everything that we are seeing now is actually past. For example, you already know that the sun is away from us and its light will reach the Earth after 8 Minutes. Actually we are seeing the sunlight which was created in the past about 8 minutes ago. Similarly, in everything in this universe we are seeing the past not the present. If we can see a sun in this universe away from 80 Million Light years and it's destroyed and we see that now means, Actually it happened 80 Million Years ago. Now in that place, there will be no evidence for that event which happened 80 Million years ago. But we are assuming that a sun destroying event is happening now. Similarly all the events that happened in this universe were past. I explained this in my last article “We can see the aliens in the future in their past” as a detailed explanation.
Finally, as far as I know, We never can travel between time but we can see the past events by the photons travel. We can see our history of humans from 6 million light years away from earth. But we cannot go 6 Million years ago. This is the beauty of Nature which allows you to see events happen but no permission to change or participate in those events. At last, whatever we are saying that time is nothing but light or photons. Then only we are saying light years for the space distances. Light is a particle which can be attracted by gravity. So that only scientists are telling us that time is different in different planets and Black holes due to Gravity. So We can never travel to the past or future. But we definitely will find a machine that can travel at more than the speed of light and land on a planet that is a million light years away from our Earth and enjoy the events which happened a million years ago. So just enjoy the timeline and never try to participate or change it.
