Does gravity have a limited range in which it can attract objects? I looked up on google, most people are saying it's infinite.. if it really is infinite then I'm confused, because if the denominator is infinite, then the result is just zero.. and in gravity's law F=[g(m1m2)] / r^2 .. if r is so...

In they site they say nanotubes can store electricity http://www.calrecycle.ca.gov/reducewaste/Power/ElectricStor.htm "Carbon nanotubes (CN) are cylinders of carbon atoms that are 1 or 2 nanometers in diameter. The molecular structure of the carbon atoms resembles wire mesh with six sided...

So I'm thinking that after I get my B.Sc in physics from an American university, I will do my Master's degree in the UK (or maybe Australia), I heard they don't require GRE? Is it easier to get admitted there?

according to the string theory, what is the difference between the strings that make the photons and the strings that make the protons? photons don't have mass and protons do, does it all ultimately rely on simply how the strings vibrate, or what? do photons' strings have lowest energy possible...

my major will be Physics and I am planning to do it all the way to Ph.D.. but does it really matter where you get your B.Sc degree? for instance, I am getting my Bachelor's from the university of New Hampshire, would it be better if i did it in say, the University of Arizona (which is ranked...

sorry there was a typo, see the last two words in cmos' quotation

that was my best guess, because I know some engineer majors actually take some basic quantum mechanics which won't make them specialists.. so apparently Leonard studied and had a little background in each topic.. and there's no 'disrespect' at all lol I am just a freshman here, all i have seen...

Why are most physicists today specialized in particle physics? do most of the physics advancements today have to do with particle physics or something? I thought about specializing in GR but i have no idea whether it's a good choice because most physicists i see in the media are particle...

what is the relationship between them? if only one of them didn't exist, would all the rest also not exist?

what kind of physics should I study to ultimately specialize in general relativity? what fields should i focus on in my B.S and M.S ?

Do physicists know exactly how many types of quarks exist? does this allow them to predict some particles should exist like Higgs Boson?

I mean teach physics at universities.. I know you need a Ph.D and MS of course, but there are a lot of branches in physics, do you have to study something particular or simply anything that has to do with physics? Also what is the difference between someone who has a Ph.D (a Doctor) and a...

Hi, I have numerous questions concerning experimental physics.. If you want to be an experimental physicist what can you study? I would like to study particle physics and quantum mechanics.. are they well involved? Also does anyone know if experimental physicists have a good income? what's...

Well, the overall of my grades is always around 85%, so fitting into college isn't a problem for me.. so I think I will be doing physics and i do have the intention of investing a decade or so in that.. hopefully I will be going to college by the end of this summer which is exciting, but I hope...

I would like to see opinions of people who entered that field.. I guess I'm asking whether or not it is too competitive
