300000 times more massive than the earth,
the sun is the perfect object for Einstein's experiment.
But how can anyone shine a beam of light around the sun?
It says the light from a distant star as it passes right next the sun in the sun's gravitational field will bend.
Because spaces bend around the sun.
But even if Einstein is right, he'll never be able to see it happen because the sun is just too bright except...
When is the sun covered so that we can see what is around it without being blinded by the light.
That only occurs during a total solar eclipse.
Here is the sun and it is blocked by the moon.
And suddenly all the stars come out.
The figure: if you have the sun here,
and there stars wait back here and the lights coming in towards you, they will bend slightly.
So to your eye, you think that the star has gone out like that.
Light going around the sun, that's something that even his mother could understand.
