~~ Time travel
The time travel thing is very popular at the present time. We have seen time travel in many science fiction movies. We all know about time machine. Whether it is a time machine or a vehicle where we get up and travel, we will go to our past / future. What ??? What is the relationship between the passage of time and the expansion or stoppage of our entire universe? Does time mean just passing day-night-year or is there some other mystery behind it ... so let's have a clear idea of time & time travel ....
Well if I tell you that you are traveling time now what would be your opinion ?? It doesn't seem strange, we usually know that only time travels when an object is moving at the speed of light, so how do you travel time from stationary to the earth ??? I hope you will get your answer after reading the whole thing. ..
Many days ago, there was a big explosion about 13.7 billion years ago, and then I was born with you, with this time. Is it just a time of birth ?? According to string theory, a total of 11 dimensions, including time, were born then, with which our universe was created ... After the birth of time, it continues to move forward. One thing you can think of is that we can only move forward, backward, right, left, up, down, in no way can we move more than that. You might say what do I mean by more than that ?? I don't have either. Because you are what I am, in the Cartesian coordinate system I & you are moving along the x, y, z axis. Our work, movement, thought, thought are all limited to these three dimensions (x, y, z).
Now imagine a flat ant in a two-dimensional coordinate system (x, y), it can always move forward & backward and left and right in no way can go up / down. Now if a three-dimensional fly comes a little above it and calls out to him "" hey, how are you ?? "" then what will that flat ant do ??
The ant will not understand anything, he will not be able to see the fly and will not be able to hear any of its calls / sounds. You must understand the reason. The reason is that the ant can never imagine anything other than its (x, y) axis.
We three-dimensional creatures are just like that. We can't imagine more than these three dimensions. Well, you might use the x, y, z axes in the Cartesian coordinate system to know the exact position of a three-dimensional object. But is that really enough for the correct position ?? Let's give an example,
Suppose you have a meeting. In addition to where the meeting will be held but must specify when it will be held. If you were simply told that the meeting would be held in such and such a place, would you be able to attend properly? Would you be confused about time? Again, if it was said that the place would be held at such a time, he would have had the same problem. So, in order to attend the meeting, you must know both the place and the time. You cannot attend a meeting just knowing the place or time. So it's clear that the fourth dimension that comes after the three dimensions is time. So time is the fourth dimension. The time we're talking about now is not the clock, minute, or second of your watch.
But can we control the time like the other three ?? The answer is we can't. If we could, we would have no past or future. We could turn to our past if we wanted to, and we could see our future if we wanted to. But we can't because we are imprisoned in three dimensions.
I have said before that our universe consists of 11 dimensions. And we are in that universe. So it can be said that we are in 11 dimensions. We will discuss the next dimension of time later. Staying in time. That is, we are in time.
Well, when we place two points along the x & y axis in the Cartesian coordinates, there will be a distance between them. Again, in a three-dimensional system, there is a distance between you and me. But now place the time scale in a quadrant. Just as there was a difference in distance between me and you in the coordinate system, there will also be a difference between me and your time. So subject to my time and your time will never be the same again.
But what do we actually see ?? Suppose you are inside the house and I am standing outside, then the time you see on your watch is the same as on my watch. But is it really so ?? If there is a time difference between you and me then why don't you or I understand that ???
We don't understand that, because we are three-dimensional. But if we could capture the time dimension or if we could feel the time dimension, we would understand the difference between your time and mine. And that would be your or my time travel.
Since there is a time difference between me and you, it can be said that both you and I are currently doing time travel. Now it must not seem strange to you that we are all time travel to each other now.
It is theoretically proven that we are all traveling time now.
