'Science for the curious'. Part 1 - "TIME; The illusion of what we call NOW"

The epic science fiction, yet real, film INTERSTELLAR directed, co-written and co-produced by Christopher Nolan is celebrating its 3rd anniversary.

The film follows a group of astronauts who travel through a wormhole in search of a new home for humanity and gives us the hint that time travel is possible.

But here the main question arises.......




IS IT ACTUALLY POSSIBLE TO TRAVEL THROUGH TIME?




TIME

Many scientists have been pondering about the question of 'What Actually Is Time?' but haven't got the answer yet. Many websites have proposed definitions of time, one of whose links I've given, but none of them stands out to be perfectly correct or to be the most accurate one.
Time is often referred to as a fourth dimension, along with three spatial dimensions.

What makes time unique is that it flows in only one direction i.e; forward. When was the last time you saw time running backwards? This flow of time in only one direction is what we call as the ARROW OF TIME.

Ludwig Boltzmann, one of the great scientists, gave us the idea about Entropy saying that universe always goes from an orderly state to a disorderly state. This gives us a clear idea about the arrow of time.

Common sense suggests that this bulb as shown below, once broken, cannot be restored again. But according to the laws of physics, THIS CAN HAPPEN!!

All you've got to do is reverse the velocities of everything; every particle, every atom, every molecule, every quark, and you're done. The bulb will be restored again without having a single scratch. Isn't this amazing?

TRAVELLING THROUGH TIME




YES! IT IS POSSIBLE TO TRAVEL THROUGH TIME. This is because past, present and future are all illusions of our mind.

This means that time doesn't actually exists, clocks exists. Time is just an agreement upon construction. Our now or present could be the future of an alien living far far away in a galaxy when it moves relative to us. Similarly, the alien's now would be our past... This all states that past is not gone and future is already decided. They all are as real as present.

Based on this idea, a great scientist named ALBERT EINSTEIN proposed a General Theory Of Relativity which united the space and time together into a fourth dimension called as SPACETIME

Einstein then proposed a hypothetical structure called WORMHOLES. These wormholes are just tunnels which connects two places in spacetime created by two blackhole's depressions when are connected. Here's the visual representation of the formation of wormhole.

This can help us to travel in two different spacetime periods and HURRAY!!! You've traveled through time.

But the problem here is that wormholes occur naturally for only about a fraction of milliseconds and then disappear. In order to keep the mouths of the tunnel open, we've got to create a huge electromagnetic field of very high strength which is not an easy job to do. And even though you've created the field, the suction power of these wormholes is so much that it would make every atom of your body to fall apart and be separated. It is, frankly speaking, for now, impossible to travel through wormholes..

But hey cheer up guys, thumbs up for the scientists who are working day and night to solve this mystery and I am damn sure that one day, time travel will be possible.
