the experiment that made Einstein a superstar

Then why do gamma rays power out of black holes? Why do these escape.

It's somewhat important to note that he did NOT get the Nobel Prize for this such discovery; he got it for the discovery of the photoelectric effect, which is a whole different thing than this.

schematic at 1:00 is totally wrong.... the light is not just conturning the star, in your schematic the light is going strait from the first star to earth and making a curve around the sun... but it is not working like that... the light going not in direction of earth/sun is curved just once... not 3 times as you showed...

According to the Nobel website, Einstein won the 1921 Nobel Prize in Physics for "his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect". This is amusing because the photoelectric effect has absolutely nothing to do with special or general relativity. It was some unrelated work which led to the concept of photons and quantum mechanics (also quite important, but less popular).

@Drkillaser sorry to tell you this but E=mc^2 is special relativity

[DrKillaser]

yes, Einstein received a nobel prize, but it wasn't for his relativity theories.. :/... but for those stuff that he discovered before special relativity (like E=mc^2)

[GiaIsTheBest]

@DrKillaser it was for his first scientific paper published.

The proof of the existens of atoms

[raedselim]

we should recognize Eddington more he was a genius 

[cusanusnicolas]

Hyperbole and nonsense. The deflection is simple refraction owing to two vectors, the first being standard Newtonian gravitational effect with frequency shift and the other a simple time delay. It has nothing to do with what "general relativity says." A similar refraction occurs when light goes through water or glass, though the causes aren't exactly the same.

[petitoo2]

Ooh please ! Lay people are trying to talk about science....

There is no 'newtonian effect' on light: no deflection of light ray, no gravitationnal redshift....

The shapiro effect (relativistic time delay) is absolutely unrelated with the shape of light trajectory ... nothing like a Fermat principle.

The deflection of light by gravity is ABSOLUTELY nothing like optical refraction. =) the causes are completely, totally, definitely not the same at all !

Don't insult Einstein's theory...

[petitoo2]

oh my ...it seems that you're not exactly a 'Lay person' ...sorry to ear that: how can you make such a wrong comment ?!

[cusanusnicolas]

@petitoo2 You are really, really sad, get yourself a decent uni education. The "Newtonian effect" was a valid, well known calculation made by Soldner in 1804, which Einstein in fact, check your history, plagiarized word for word, then later doubled the prediction. That was based on standard grav loss of energy. The additional refraction is due to slower clock speed, claimed by Einstein, but it really has nothing to do with relativity. Why do I bother with youtube idiots.

[VERGIS92]

@cusanusnicolas Haha, when did you come up with this theory? Effects of GR have been scrutinized one by one, light bending,  and time dilation have been confirmed, secondly it explained the orbit of mercury which Newton could not. scientists before Einstein had completely ignored these facts, you are a good historian but physics- illiterate. Scientists do disagree on things, but not at this level
