Is it possible ? Time Travel –Mohmoud El-Gendy

What is time ? NewtonEinstein not Time is not an absolute truth Time is an absolute truth

How did Einstein prove that time is not an absolute truth ?

100 Km/ Hr 120 Km/ Hr 120 – 100 = 20 Km/ Hr

Km/ Sec Light Beam Km/ Sec – = Km/ Sec Km/ Sec Light Beam Km/ Sec = Km/ Sec

That means that the speed of light is constant.

Time Dilation (The Twin Paradox) Time runs slower on moving object How ??

2 Cm 2 Sec 1 Cm 1 Sec 0,5 Cm

The Faster goes the object the more distance runs the light beam the more time gets slower But we can only notice the time dilation in big velocities (more than 70% of the speed of light)

Can we travel to the past ?? It is possible But yet it is impossible

It is possible Time goes with a positive charge, when an object reaches the speed of light the time charge becomes neutral which means that time is frozen When the object passes the speed of light the time charge becomes negative and then it goes back in time

But yet it is impossible It is impossible because nothing can travel with the speed of light up till now Why ???
