Photons have no mass and thus should not be effected by gravitational force, yet photons (light) does not escape a black hole. Is this perhaps secondary to the distortion in space-time caused by the very large mass of the black hole ?

Where did the universe come from? When and how did it all begin? How did the universe develop into its present form? Why is there a universe at all? What is it that makes existence here and now possible? Why is there something rather than nothing? Where Do We Come From? What Are We? Where Are We Going?who knows the relations between mind and matter ?what is free will? the nature of consciousness? the forces that caused the big bang - or even what came before the big bang? we should believe our reason and mathematics anyway,why?the limits of reason? the limits of mathematics?if science can explains these questions,I will ask why they are at all comprehensible?why?hehe,why exists answer,why exists these questions,why ask?

Don't answer if you are going to be stupid. If you have actual knowledge, please tell me. If it's a hoax, or crazy set of coincidences, please explain it to me. If you believe it's true, please give evidence.

If you dropped a led ball from the top of the former World Trade Center towers 1 or 2. How long would it take to hit the ground?? In a Vacume?? What would be the Terminal Velocity at sea level??
The official time the towers fell in the 911 commision report was 10 seconds. Is there a formula to figure out or estimate closely how much resistance the top floors above the impact point would have met on the way down verses resistance of air? Also note in the video the buildings fell at approx 10 seconds as well. How is this possible??

So, okay, I've got a question, being not an entirely physics junkie yet. This may be a simple answer, but maybe not...

Electrons are negatively charged, and protons are positively charged and neutrons are basically neutral, right?

So, all things being equal I'm assuming protons ane electrons have approximately the same strength of positive and negative charge yes?

And like charges repel whereas opposite charges attract?

So, why is it that atoms prefer the structure of protons in the nucleus and electrons in the shells as opposed to electrons in the nucleus and protons in the shells?? Shouldn't both ways of doing it be equally viable?

IE, would it be possible to have a nucleus of electrons and neutrons orbited by a shell of protons? If so, or if not, why?

They both seem to have the same properties of attracting the other, and repelling themselves. So, one would think the same structure could be built either way?

Why isn't it? Or... is it in some instances?

Let's say there is a bridge nearby the ocean (like Golden Gate bridge in San-Francisco). On the bridge there are two cars: one is moving along the bridge, the other one is at a standstill . A strong wind is blowing from the ocean (with an equal force on every part of the bridge). Which car will be blown away first? The one that is moving or the one that is at a standstill? Why?
