1. ## A "Theory" of the Universe

You know your theory is not that bad. After all, it is the only thing that can make something from nothing. Yet, when you have matter and antimatter equal zero when taking the sum of their masses, you should have zero again. I believe that matter and antimatter cancel out in contact. What would mean 'in contact' though, because we are talking about an area where space-time doesn't exist. In contact almost means in existance in this case. When these two things are in existance, they destroy each other, meaning that it would go back down to zero again. Therefore, perhaps antimatter and matter universes are not touching. Maybe it isn't in existance, maybe it really does mean touching each other. Yet, at the big bang, the singularity was 'touching', how does matter and antimatter spew out from the same place without destroying each other?
2. ## How do you manually do a fractional exponent?

Thanks, that really helps. All I really needed was to know that x^1/2 is the same as [sqrt x]. But thanks for going into greater detail, now i understand it. As for the absolute value question, I was an idiot. Anyway, how exactly could you do something like this: 3^4!. I thought you just do the factorial than use that as your exponent. But then, I realized that you can't because PEMDAS says you do Exponents first, multiplication second. Would you do 3^24 or 81!? Would it even be either of these? Math gets really confusing sometimes!
3. ## Does time go faster for an object moving faster?

I heard that einstein created a theorum about how at higher speeds, time moves at different pace. Does anybody think this is possible?
4. ## Anti-gravity theory

Are you a scientist by any means, because i am only a 9th grader? Anyway, I wonder if you could give me a quick briefing of 'strong force', because i am working on a theory about how the universe began. It has come a long way. In the beginning, I included antimatter as a viable fact, than I disproved it somehow. I wrote a lot of notes on how it works, and who really knows if it is right, but if you could, i could describe my theory. I want to either prove or disprove it, I have done a lot of work on it and I can't seem to stop because I think it is right.
5. ## 11 dimensions

I think that there are 11 dimensions, yet the only thing that has access to the others is gravity. Gravity is considered a weak force, but that is because it is often in the other dimensions. Gravity of a black hole, for instance, is well into the 11th dimension.
6. ## Anti-gravity theory

Does such a thing exist? Can it? We probably can't stop it, but it seems very hard to understand. Gravity holds together the protons and neutrons of atoms nuclei, so how can antigravity work? What I have trouble with is this. Is there an antimatter? Maybe antigravity exists because that is how antimatter and matter relate. Maybe antimatter is gravitational to antimatter. Yet matter to antimatter is antigravity. In fact, is there a proven such thing as antimatter? I have heard mentions of it, but I wondered if it were proven to exist in the scientific community.

9. ## How do you manually do a fractional exponent?

I understand exponents, I eventually figured out how you manually do negative exponents, but how do you do something like: 3^.4? How do you do something like: abs[3]^3? Can you multiply together absolute values? I am only in algebra right now, not even geometry, but nobody else even cares how they do as long as they pass, but i want to understand this stuff!
10. ## Imaginary number intuitively?

I ended up teaching myself about imaginary numbers. Here is a good way to do that for yourself. First take the basics: i = [sqrt -1]' date=' i^2 = -1. So, if you add a coefficient, you change it to ni, or for example: 2i. It really means 2([sqrt -1']), meaning 2 [sqrt -1] which makes the number imaginary. Here is the best way to apply it, just treat it like it is a real number, even though it isn't. 4i^2 equals -4 because you only square i, and i^2 is -1, so it is the same as saying 4 times negative 1. But if you do this: (4i)^2, you square 4 and i, which is the same as saying 4i times 4i. This makes 16i^2, which means -16. See, you can teach yourself imaginary numbers by applying what you already understand about real numbers. Try to figure out what i^3 is. Here is one even I haven't done yet, n^i. Good luck with them!

12. ## 60% of Americans believe life exists on other planets

I really wonder if the government truly knows something about it that they are not willing to tell. Why would it even hide something of such high regard. The government is made up of people just like us, and if stripped to nothing but themselves, they are also people. Why should certain people be let in on something we don't, simply because they have a government career? The people they run include them, even George Bush won't be in government forever, yet he is let in on something. It is seriously a load of bull!
13. ## 60% of Americans believe life exists on other planets

What I wonder is how people can almost doubt it. It is true that the probability of life developing on earth even was slim to none. However, the universe is an awfully big place. Hell, the galaxy is an awfully big place. Should we even doubt that there is life elsewhere in the universe?

15. ## Temperature

is there an absolute high temperature?
