I like how each new idea of the universe was based around the idea that our little corner of space is the center of the universe. How egotistical we humans are...

It's not really that photons have mass. The gravity of the black hole is not really acting on the photons themselves but rather the space through which they are travelling. The photons still travel in a straight line but the space through which they move is being curved, so much so that space and time itself completely curves in on itself, taking the photons with them.

Since universe exploded why shouldn't the epicenter of explosion be denser??

@Artfryne Indeed. Then, think about how simple our ideas today will seem in 50 more years...

[Artfryne]

just imagine trying to explain quantum physics to the earliest astronomers... they scarcely had any idea of the science to come in the following centuries.

[FIGHTFANNERD3]

they need this in schools
