Special & General Relativity made easy =p 4/4

Do you have a fascination with Einstein's theory of relativity? What I mean is, do you find yourself fascinated by the weird predictions of this theory and would like to get to the bottom of it once and for all? While relativity Is not a light read (all puns here are accidental, BTW), pieces of it can be easily understood. This is particularly the case with Special Relativity.

I'll attempt to explain in an intuitive way, why the time of a rapidly traveling object seems (from your point of view) to slow down. That is, why an object seems to age more slowly when it travels at very high speeds.

You will have to take two things on faith: the speed of light is constant (an experimental fact) and that all frames of reference traveling at constant speed have equal validity. The explanations that follow rest completely on these two conditions.

Our brains are wired for survival purposes for a 3 dimensional and very slow moving environment. Compared to the speed of light, the everyday objects that our brains perceive and reason about are barely moving at all. Our common sense about how the world works is specialized for dealing with an almost non-moving or static environment (again, that's compared to the speed of light).

What this means, is that what our common sense tells us about our sluggish everyday world is mostly correct but otherwise it's judgements cannot be trusted when dealing with extremely fast things.

So when experiments and mathematics tell us things that are contrary to our crude perceptions about how things should work, we find it to be totally bizarre

You're pathetic, you should really stop stealing video's off marcellojun and adding some stupid emoticon. Shame on you, make your own videos.

[yourboycal]

@Alexrulz99 a) Welcome troll b) marcellojun did not make this series c) these videos are copyright free from the persons own website caasiopeiaproject d) marcellojun is credited in the video section e) i asked marcellojun via email if he wants them removed f) you failed all all counts g) the true creators are credited in the info section if you took two seconds to click

back to your hole troll. =D

[yourboycal]

@Alexrulz99 "You're pathetic"

Not as much as you are . How many trolls does it take to change a light bulb?

[Alexrulz99]

@yourboycal Sorry for my misunderstanding.

[ghufranullah]

Hey nice videos! .. I have a question .. if that truck in the video is moving with the speed of light in a uniform direction and the bowler throws a ball wouldn't the ball be faster than the speed of light relative to the Guy outside?? O_o ....

[Alexrulz99]

@yourboycal Wow, I do admit, you owned me there.
