I am a sophmore in H.S. and would like to learn the basics of physics and physicists. What are some good physics colleges? How much do physicists make? Do you have to teach in a university as a physics career? Where can I learn more about basic physics? My main question about physics are: What is space-time? I read a little of Stephen Hawkings A Brief History of Time and I could not understand exactly what space-time was. Also, how many dimensions of the universe are there, how do they interact or correlate, and what are their purposes? Does light have mass? If so, is it the lightest particle? Is it a particle? Does this correspond with the Wave Particle Duality? If not, how does light bend? Another question of mine is quantum computing. What is all this about? What is the purpose? Please answer my questions. I would love to learn as much as I can about physics. Also, is there a relationship between physics and philosophy? I really enjoy philosophy.
