I have heard countless times from dumb people that "time" can be speed up and slowed down and is relative, because if you move at light speed, time speeds up.
So there are actually people who are clueless about what time even is, but most importantly clueless about theory of relativity.
Some will even be as dumb to claim theory of relativity disproves A theory of time.
But sadly, not everyone is born with 160 IQ, and many who are, are still unable to understand basic things. For them, time is some magical dimension.
What is time?
time is movement of matter.
there is no way to meassure time other than movement of matter.
Does light speed speed up time?
No.
Light speed slows you down.
this isnt difficult to understand. Moving at light speed means every atom in your body moves significantly slower. Your thoughts become thousand times slower. Your vision becomes thousands of times slower.
If someone who was standing still observed you while you were moving at light speed, to him, you would be frozen in place.
And thats what basically happens. Light speed does not speed up time or defeat A theory of time.
What happens is that objects moving at light speed become significantly slower (probably due to their extreme speed clashing with gravity which slows them down considerably).
So there is still one present moment, and not multiple "presents". A time theory isnt disproved.
there are truly no multiple present moments, and anyone who concludes that from theory of relativity should probably quit science and do something more suitable for his brain, for example playing with LEGO.
