TIME DILATION

according to theory of relativity there is a postulate used that nothing can travel higher than the speed of light

means

more than

299792458m/s

and our universe is limited at this speed so if any object will travel at the speed of light then the physical forces stop that.

means any object can travel 99.99% of speed of light but not 100%.

so

if any object goes near the speed of light then the time dilation occurs in order to maintain the physical laws and a limited speed of universe.

here

in pic

the formula of time dilation is given.

Travelling into the future is a real thing.

lets take an example

1 second for us is not the same as 1 second for a person is in space

Essentially time flows slower from someone with respect to someone else.

The technical term for this is *Time Dilation*

In simple words, it means Slowing Down of Time

So there are two ways in which time can slow down.

• Relativistic Time Dilation (Special Relativity)

• Gravitational Time Dilation (General Relativity)

Relativistic Time Dilation

This concept came out when Albert Einstein published his Special Theory of Relativity in 1905.

What it says is that time flows slower for anything is moving faster or closer with speed of light

Let's scale this up to what we call Relativistic Speeds

Gravitational Time Dilation

This concept came around when Albert Einstein published the General Theory of Relativity in 1915.

The concept is that presence of a Gravitational Field slows down Time.

The stronger the gravity, the more is the time dilation.
