- If there are a finite number of atoms in the entire universe, that means there is still a finite number of permutations of atoms possible. Can our very existence occur again then on a infinite time scale if we are just made out of a certain permutation atoms?
- How does the Maxwell-Boltzmann distribution allow us to solve the probability of particular particle arrangements over a given of time?
- If pi stops having any practical use after it reaches a finite number of digits, how can mathematicians discover the digits that come after this limit?

- Are the physics in Total Recall correct?
- Can photons be used as propulsion?
- One of the most fundamental principles taught is that everything wants to be in the lowest energy state possible. Why is this the case?
- If, during a fusion event, the binding energy per nucleon is increased dramatically, how can energy also be released from the event?

| Posted: 23 Jun 2016 05:00 AM PDT Hi reddit! I'm a renowned eye surgeon, researcher and lecturer who has worked with the LA Lakers, Kings, numerous other Gold-metal athletes and A-list celebrities. I have spent the last 20+ years of my career working with the most advanced and cutting edge technologies to improve vision and eye health. I know what works, what doesn't, the newest implantable lenses, the biggest myths & fears of so many Americans that may be avoided, if they only had the right information. June is Cataract Awareness Month and it's always been associated as a grandma's issue – well, no longer. Cataracts are now affects Americans as young as their late 40s and 50s! I'll be back at 3:30 pm EST (12:30 pm PST, 8:30 pm UTC) to answer your questions, ask me anything! [link] [comments]  |

| Posted: 23 Jun 2016 05:18 AM PDT I have been reading Max Tegmark's book "Our Mathematical Universe" and in later chapters he briefly discusses that the Maxwell-Boltzmann Distribution shows that the probability of a particular arrangement of molecules, such as the exact molecular structure of your brain, complete with all your thoughts and memories is more likely to occur in other regions of space and/or other universes (Many-Worlds interpretation of Quantum Mechanics) than through evolution. This is known as the Boltzmann Brain and is a hypothesized self aware entity which arises due to random fluctuations out of a state of chaos. [link] [comments]  |
| Posted: 22 Jun 2016 05:20 PM PDT Sources like this ( http://gizmodo.com/5985858/how-many-digits-of-pi-do-you-really-need ) claim that the "the circumference of the observable universe" can be measured "to within the width of a single hydrogen atom" with only about 39 digits of pi. So how can any more specific calculations of pi be accurately measured? [link] [comments]  |
| Does the Moon's gravity have a tidal effect on bodies of liquid that are underground? Posted: 23 Jun 2016 06:56 AM PDT The Moon's gravitational pull is known to cause the tides in the world's oceans, which got me wondering whether or not underground bodies are similarly affected, eg. aquifers/water courses, water in cave systems, oil fields etc. The Moon's gravity affects liquids on the surface from 384,000km away, so surely it isn't inconceivable that this effect is also going on simultaneously under the surface?

| Are the physics in Total Recall correct? Posted: 22 Jun 2016 01:53 PM PDT For those who haven't seen the movie, it features a tunnel between Australia and Britain, which allows fast travel in a giant vehicle that is dropped down the shaft, to emerge at the other side. I'm fine with that part (and ignoring the impossibility of constructing such a thing), what I'm questioning is the forces experienced by the people in the vehicle. For the 'downward' leg of the journey, while the vehicle is in freefall, they seem to experience gravity just the same as if they were standing on the surface. When they near the core (going past it rather than directly through), there is a period of weightlessness, then on the 'upward' part of the journey they appear to experience normal gravity again, in the other direction (the seats rotate so they aren't upsidedown). So, is this correct? [link] [comments]  |
| Can photons be used as propulsion? Posted: 22 Jun 2016 11:07 AM PDT Can photons or light be used as propulsion? If so, how would we create propulsion with photons and how efficient would it be? [link] [comments]  |
| Posted: 22 Jun 2016 08:54 AM PDT Is there a subatomic explanation? Or is this just the way it is for this dimension? [link] [comments]  |

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 22 Jun 2016 08:05 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| How significantly is light affected by moving through a medium that is in motion? Posted: 22 Jun 2016 10:53 AM PDT For example, (and please excuse the crudeness of this diagram and of my handwriting), would photons get stuck here, where they're swimming upriver just as fast as the current is flowing, so to speak.

| Posted: 22 Jun 2016 08:09 AM PDT For example, if I had a cylindrical container half full (or half empty =p ) of water, and I also had a piston that perfectly fit the container, enough so that no water could escape through the crack, would the water be compressed into denser water? Would the water turn into steam? Would the piston not be able to push down onto the water? If said piston wasn't able to push down onto the water, what if I had an infinitely strong piston pushing down onto the water as well as an infinitely strong container holding the water?

| Posted: 22 Jun 2016 06:51 AM PDT If all the dots combined would be equall the the number of all the dots in a circle with the area of 2rpi with r the lenght of the pendulum? [link] [comments]  |
| How come in sword fights, one sword can not slice through another? Posted: 21 Jun 2016 10:53 PM PDT With both swords swinging at each other with great force, and both have extremely sharp edges, how is it that neither be chopped or broken by the other? [link] [comments]  |
