Big Travel Theory

Our universe was created 13.7 billion years ago. The Big Bang theory proposes that this creation resulted from the rapid expansion of matter with infinitely large density and high temperature, which marked the true origin of the universe. Physicists decided to introduce a new phenomenon called time, and agreed that “time” was born once the Big Bang banged. Simply defined, time is the measure of durations of events and the intervals between them. In non-relativistic physics, physicists consider time a scalar quantity like mass, length, and temperature. The mass of an object is the same whether it is on Earth or in Space, and since time is considered a scalar quantity that means it is very simple and straight-forward. Time flows constantly disregarding one’s position in the universe. However, on November 25, 1915, Einstein discovered that time is relative, meaning time cannot be constantly flowing everywhere; instead, time can be warped. The General Theory of Relativity introduces new understandings about time and the power it …show more content…
The two suggested ways above show that time can be slowed down to the point where time travelling to the future is clearly observed. However, time travel to the past is close to impossible, simply because it results in many problems and paradoxes. One famous paradox is that of the man without parents. It says that: What happens if a man travelled back in time and killed his parents before he was born? The problem this paradox states is that if the man killed his parents before he was born, then how did he get born to travel back in time to kill his parents in the first place? (Kaku, n.d.) In addition, in order to travel back in time, one must travel faster than the cosmic speed limit. Suppose it’s possible to exceed light’s speed, travelling to the past is somehow logically impossible. A time traveller cannot travel to a
