  1. I have a theory that, whilst it may not satisfy your question, and may give you a few more questions as well as theoretical answers. I am also in highschool and I'm terrible at physics so don't take anything I say to heart and always with a pinch of salt. My first theory is about the expansion of the universe. I personally think that the universe is like a plastic bag, it has a certain amount of weight it can hold before it gives out and splits, however, since the universe is much larger than a plastic bag and infinitely stronger, it can hold a lot more weight. But, it's not just about the weight, it is about the size as well, and I think that the universe is ever expanding because of its need to hold all of the matter inside it and be able to take in new matter. And since it is always getting "heavier" in a theoretical sense, it is always expanding faster. This is why when the stars die and implode on themselves, the universe will expand faster, and will always have space for more emptiness. This leads on to the next part of my theory, the black/dark matter. My theory is that dark matter is taken into our universe at the edge of it's reaches by the expansion, and it never decays because it hasn't been destroyed yet, which I will explain later on. I believe that once the universe expands to a certain point, put simply it will collapse into a mass merger of atoms and particles, with black/dark matter being right at the center, forced to merge and split apart into different atoms, creating new elements and new chemical reactions resulting in a new big bang born out of what we perceive to be nothingness, which in actual fact, could be classed as everything. Meaning that our universe may have been recycled many times before. This also means that there is no end to life, only a, in a scale of universal time, brief pause, before new life is created. Thank you for taking the time to read this. Yours sincerely, Thespaceotaku
  2. Eventually, due to "dark energy", the universe will be expanding so quickly that it will break the speed of light. This, if I am not wrong, already happened at the beginning of the universe for 10 to the power of -43 seconds. So, what will happen once the universe is expanding at that speed. Will the laws of objects moving faster than the speed of light apply (mass increasing, time slowing down ect.)? I have to stress I am my no means an expert on the matter, if anyone could point out mistakes in this question please do. All answers would be much appreciated.
  3. Just a heads-up that the current edition of New Scientist contains an interesting graphic on how the main aspects of modern physics fit together - quantum theory, relativity etc, and the problems that remain to be solved. If you go to the New Scientist website, you can download a poster as a PDF file. I would attach the PDF, but I might be infringing copyright or something. Apologies if this has already been posted.
  4. Hey guys! Its been 8 months since i ve started the hobby of astronomy.I would like to dig deeper now,i am looking for a book in astrophysics that involves mostly formulas and mathematics.With so many books in the market its hard to defferentiate science books from just books with information about the subject Thanks! -Kronos
  5. Okay so I chose to take a year to decide which career to study, I've always been interested in physics and astronomy but I think I will go on and pick Chemistry. Any tips or ideas on what to do after?
  6. To my understanding, matter is just crystallized energy. So is dark matter the crystallized form of dark energy? Sorry if this is a bit of a stupid question, just couldn't get it off my mind. Any answers would be much appreciated - thanks.
  7. The definition of a moon is a natural object (or satellite) that orbits a planet. To my understanding Saturn's rings are made up of space debris, and they must orbit around the planet. Does that mean that each individual piece of debris and dust in Saturn's rings, and other planet's rings, count as moons?
  8. I am not sure how much this is to do with astronomy but I was wondering whether dry ice could be used as a fuel source some how. Just part of an idea I was thinking up. I am only 13 so this is probably a stupid question. Thanks.
