Theres also one famous experiment: they had 2 atomic clock, they put 1 of them into an airplane and set it to fly some hours, after it stopped they realized clocks had differences they shouldnt have
time is not absolute, it depends on the object velocity and the gravity on that space
"TIME IS NOT ABSOLUTE" this concept seems easy to understand but its not
once u understand it u wont say stephen didnt answer properly... now u can only say u didnt understand the answer as u only know basic physics

again as i said u cant talk about a before big bang, time didnt existed, and u know scientists cant afirm things without proof
a well-known technology that aplies einstein general relativity theory (GRT) is the GPS system: corrections are made to their clocks every minute acording to the GRT becoz of gps satelites velocity n gravity at that height.

Questions that are not properly answered will never go away. He can't claim that the question "what happened before the big bang" its illegitimate. Why events before the big bang can have no consequences and so should not form part of a scientific model of the universe? should we just cut them out of the model and just say that the big bang was the beginning of time? Obviously questions such as what or who set up the conditions for the big bang are not questions that science addresses.

Cosmos represent its initial creation in all way of life with smaller models. Human birth it is the most similar model. We will not be able to explain the creation of big bang since we are not able to explain the first moment of our birth. So it is no mater the size but the ability that we have to caught the start point. We are 'programmed' to understand our existence but not the final points birth-death. Probably God is this kind who birth and death have the same point of ignition..

What are you, a baby? The point he's talking about is not the one you draw on paper with your pen. Geometrically speaking, a point has no dimensions. A small circle. Unbelievable.
