particles like protons and maybe photons, they are always spherical why? do they create a gravitational field?

What do they mean by this: "Albert Einstein's concept of gravity is wrong, and gravity becomes repulsive instead of attractive when acting at great distances." I found it here: http://www.jpl.nasa.gov/news/news.cfm?release=2011-149 in the second paragraph. could anyone explain this with...

I need to know when did the first black holes appear?

How did dark matter form? and is dark energy a result of dark matter like gravity is a result of ordinary matter?

But I've read in a book that if the universe contracted back into a singularity and banged again, Earth wouldn't necessarily form again, it's like throwing the dice again.. well, at least that's what I understood. And I thought that scientists still aren't sure if we are surrendering to a...

I'm not sure if this is the correct section but I have a question I would like to be answered, I was thinking since a system will have many more possible disordered states than ordered states, then would this mean that if we were normally moving forward in time, and for example, some glass broke...

yes I mean when you are studying at college, ME has more mathematics which can make it harder than EE.. I don't know that's what heard

If you really like it as you seem to be, then don't hesitate to enter that field, you might do great success in this field, who knows? life is full of risks, if you aren't willing to take any risk then stay at home, although you should think wisely before taking any risk.. in your case, you look...

I was told that M.E is one of the hardest, if not the hardest, engineering fields, so my question is, is E.E any easier than M.E ?

oh ok, but in your opinion, would mechanical engineering aid you with any background that will benefit you for quantum physics?

If you have a degree in mechanical engineering, can you do an M.A in quantum physics? is it about your previous certificate? or simply your ability to handle the following field?

as we move forth in time, does the universe become more or less complex? is this related to the theory of thermodynamics? I just need a brief explanation I'm a bit confused. Thanks!

I mean there are certainly unsolved equations and mysteries in physics and maybe maths, i said perhaps our generation would be able to solve some of them

What are some important theories in physics that are expected to be discovered within our generation?

is it true that they spin the direction you think of, whether it was clockwise or counter clockwise, it will follow your mind.. is that true?
