We are always curious about time travel which is hard to believe but some people say it is possible to time travel with advanced technology while others say it’s a myth. First of all what is time travel? It is a concept of movement between certain points in time. We always come across cartoons or movies where people go back and forth in time using a hypothetical device known as time machine.
When it all started ?
You may be wondering when did all these talks started. The first time this concept was mentioned was in a novel named “The Time Machine”, written by H.G Wells and published by Heinemann in 1895. We would have also come across ancient myths where some characters had the power to skip forward in time. There is also a Hindu mythology where the king “Raivata Kakudmi”, travels to heaven in order to meet the creator Brahma. There are a lot of cartoons which uses the concept of time travel to entertain the kids.
Science and time travel
What does science mention about time travel? In our physics book we all would have learnt about special and general relativity and also types of motion in space. Theoretically speaking, time travel is possible. According to general relativity, time travel is possible by moving faster than the speed of light , which includes cosmic strings, warm holes and Alcubierre drives. Some of us would have seen the movie interstellar in which the main character travels to the future using black hole concept and meets his daughter who had become way too older than him. Stephen Hawking suggests that the fundamental laws of nature prevent time travel. Still physicist cannot come to a conclusion on time travel but we all find it as an interesting topic to talk about.
Time Machine
Most of us are curious on how does a time machine would look like if it really existed. No one knows How a time machine looks, because real time machine doesn’t exist till date, but from seeing in science fictions and cartoons, we can say that it looks like vintage cars without a roof with some clocks installed in it. whatever maybe a time machine, if it existed won’t we all be standing in line to travel in it?
