What is Time?
Time is a thing by which all the calculations were done in this world. This time is calculated using earth rotation. It is an irreversible thing we can't able to get the lost 1 second. Based on this time, everyone's life is described as past, present, and future. With the presence of the sun, day and night get calculated. This is on Earth with gravity. Time will differ with respect to gravity. The higher the gravity slower the time.
What is Time Travel?
It is one of the interesting myths (may or may not be a myth) around the world. In our life, we all think in some situations. We will think about our lives and think about what will happen if this situation has not happened in our past. Time travel is nothing but moving across time. In every second we are traveling to the future. So, all are time travelers. Lol. Time-traveling to the past had many myths and theories. Let us discuss some strange topics in time travel
What happens to a person traveling to the past?
Assume a person aged 30 traveling to the past age of 20. Somehow this guy traveled to his past to change something in his or someone's life. There are 2 possibilities here- That guy will travel again to the future from age 20 to age 30. If this happens he will not know what are all the changes that he went through for the past 10 years.
- He needs to live his life again in the timeline of age 20 to 30. So, he knows what are all the things he faced from age 20 to 30. But at age 30, there will be two persons in that time zone. One with age 30 and the other with age 40. In the real world, we have seen many twins that are connected with their soul. What will happen if we live our life with our future version. It may affect the mental behavior of that traveler.
The world revolves with the butterfly effect. It is nothing but all the happenings in this world are interrelated. A small action that you have done here will show impact in other countries. Like the president, some orders will indirectly affect other countries. We will see this topic in a separate article. If you are traveling to the past and changing something it may affect other's life indirectly. Not only your life will get a change it will change another person's life too.
Is time travel is possible if a person is traveling at light speed.
The first thing here is at present no such type of machine was invented. In my point of view, this statement is a myth.
If anyone traveled at that much speed they will feel like they have spent many years traveling but when they land in the real world only a few days will get passed. But when someone tried to build this machine on the earth, it may affect earth rotation because in one place that machine is used to travel at light speed. So it may speed up earth rotation or Earth orbit may get changed. Imagine a ball having a fire ignition in one end. When this machine starts ignition that ball will rotate more than current.
Will the time machine be invented
Yes, there is a possibility to invent time machines in the future. But it will not be a machine to travel to the past. It will make you stay in the present and it will slow down your future. Assume I am the person who will be in that machine. The objective of that machine is to make me travel at light speed for 10 minutes of our earth time. Other people on earth crossed 10 minutes but for me, in that machine, it will be many years. So, my point is rather than changing the happened past, you can do a lot more by postponing your future. In 10 minutes not that many changes will occur in this world. But if a group of people was in this type of machine they may get advanced ideas and if that were implemented there is more chances for us to live in an advanced world.
Apart from my point of view, there is a scientist who declared that he had completed his equation on time travel and he convinced others that his equation was theoretically satisfied.
Grandfather Paradox
If you travel to the past and kill your grand parents before your parents birth, then how can you will be present there to kill them. There is no answer for this question. It will be like a loop that will not give any answers.
