Can we travel in time? The short answer is yes! It is true. We all have the opportunity to make a leap forward in time, even if we do not realize it. If you wanted to go in the future, just go to bed and wake up a few hours later, would not you? Of course, the point is cheating. We want to go back and redo the stupid mistakes we made several years ago. Who did not wish they could go back and talk to their car 15? Tell them not to make the mistakes they made (or they will). Or maybe you’d rather travel 500 years in the future and see the flying cars we were promised for the year 2000. Fortunately, it’s theoretically possible to travel back in time.
In fact, there is no law of physics that prevents it from traveling in time. Thus, according to all the laws of physics as we know it, it is entirely possible to travel at will. But, as the saying goes, with great power, there is a great responsibility. Time travel is an extremely dangerous endeavor with devastating consequences, and it is full of paradoxes.
For example, what if it came back in time and engêchais the Second World War? Sounds like a brilliant idea, does not it? Countless lives would be saved, he would be acclaimed as a hero! Not necessarily. Although I would like to save lives, I destroyed others. What about all the technology we rely on today that was developed during the war, such as jet engines and nuclear power. In fact, the map of the world could be completely different. In fact, we could be worse than just letting history as it was.
Another famous paradox of time travel is the paradox of the grandfather, who essentially states that if, for example, it was said, I went to a time when my parents were born and to avoid that my grandfather met my grandmother. My parents would not have to comply, and they would never have been born. So how could I go back in time to prevent my grandparents from meeting in the first place.
So we can see that time travel could be a bad idea, but to say that we really want to go back in time, how do we do it? First, you have to understand how time.
Time is something we are all very familiar with, we all know what it is, but we can not see, touch, we can not interact in any way, we can only observe. Isaac Newton thought that time was constant and never deviated, which obviously make it impossible to travel in time. Even Einstein thought it was impossible, but it is his equations that make it possible. Einstein theorized that space and time are inextricably bound in what he called space-time. So, in theory, if I had to leave space behind with something very powerful like a black hole, I would also distort the time.
