Understanding Time

According to physicist Albert Einstein, time is not a constant phenomenon as it appears, but is an illusion, and can vary from different vantage points.

Space is three-dimensional, and Time, according to the famous physicist, is the fourth dimension. It also speeds up or slows down, so is actually subjective, as stated in his Theory Of Special Relativity.

Einstein's theory of general relativity says that Time can be bent, stretched and squeezed, and the four-dimensional fabric with a huge mass creates a dimple, or bending of Space-Time, causing gravity.

The Theory of general relativity suggests that if an object is faster than the speed of light, which is 299,792 km per second, and in a vacuum(no air). This also would mean that such objects would have an infinite mass and a zero-length, which is not possible.

Various fictional and semi-fictional methods are discussed in order to build a time machine. It is supposed to have ‘antimatter’, ‘negative-energy density’ and other exotic technology in order to work.

Time Travel, in pop culture and theory, presents many unique situations and paradoxes, the most famous of them being the Grandfather Paradox, which is dealt with in the Terminator movies, along with Back To The Future.

The Science Fiction’s holy grail, Time Travel has been a popular topic in various books, movies and TV series for decades.

Time Travel has been popularized in movies like Interstellar, episodes of Doctor Who, Back To The Future, and even the first Superman movie made in the 70s.

Wormholes are points in Space-Time in which the two different points are connected, allowing instant transportation of matter.

I have always been interested in the concept of time and time travel, as it is always as mind boggling as it is simple, and this article I found useful to introduce paradoxes which arise as part of time travel.

Portal Guns are some of the most interesting theoretical devices that have been thought up in Science Fiction, and today, I will be diving into the specifics as to how they could be possible.
