- How come, if we know the genetic sequence of an organism, we can't just...generate it? Could this ever be possible, and why or why not?
- Can time be divided into infinitely small increments?
- Why does a flat universe indicate an infinite universe?
- What's the deepest hole we could reasonably dig with our current level of technology? If you fell down it, how long would it take to hit the bottom?
- In the 19th century, the concept of ether was disproven, but the Higgs field sounds a lot like ether to me. How are they different?
- What's the effect of sound in a object moving at high speeds (as much as to experience time dilation) ? Also , will our thought processes be slower and would we be aware of that?
- No information can travel faster than c, so no event inside an event horizon can have any causal effect on the external universe. How then do external objects "know" the mass of a black hole? Is that information somehow accumulated at/outside the event horizon over the life of the black hole?
- What is the difference between two vectors or lines being perpendicular v. being orthogonal? Or, if there is no difference, why do we have two different terms to describe the same thing?
- Specifically, how are senescent cells harmful to the body?

- If it only takes 23 people in a room to have a 50% chance that two of them share a birthday, how many shuffles of a standard card deck does it take to have a 50% chance that two of them are the same (they end in the same order of cards in the deck) ?
- Did LIGO get incredibly lucky with two black holes colliding or are these fairly frequent?
- With technology advancing to a point where stem cells are being used to regrow new body parts and attach them, but do the nerves attach also?

| Is there a scientific explanation for the phenomenon of humor? Posted: 14 Feb 2016 06:43 AM PST When you think about it, humor and laughter are really odd. Why do certain situations cause you to uncontrollably seize up and make loud gaspy happy shouts? Does it serve a function? Do any other animals understand humor, and do they find the same types of things funny? [link] [comments]  |

| Posted: 15 Feb 2016 05:46 AM PST If someone standing behind me talks to me , or if I use headphones to listen to music while moving in a vehicle close to the speed of light, how would it feel like? [link] [comments]  |

| Posted: 14 Feb 2016 05:06 PM PST I was reading Gilbert Strang's Linear Algebra and its Applications, and came across a chapter on orthogonality. I can see no difference between orthogonality and perpendicularity, so I was wondering if there actually was one. [link] [comments]  |
| Specifically, how are senescent cells harmful to the body? Posted: 15 Feb 2016 01:04 AM PST It's been in the news recently that mice who have been genetically engineered to destroy their senescent cells upon creation of their signature p16 protein (not sure if that's redundant) have had increased healthy lifespans by about 25%. In this article by GEN News (http://www.genengnews.com/gen-news-highlights/shedding-doddering-cells-could-extend-lifespan-healthspan/81252340/), it's claimed that the senescent cells are harmful to the body because they "[consume] resources and [secrete] factors that are, on the whole, harmful." What factors do senescent cells secrete that are harmful? [link] [comments]  |
| How can an up quark decay into a down quark? Posted: 14 Feb 2016 07:31 AM PST I am puzzled as to how this happens since the up quark is lighter than a down quark. The process calls for a W+ boson to be emitted from an up quark, converting the up into a down. Since the up quark is ~1.8-3.0MeV, and the down quark is ~4.8MeV, how does this "decay" happen?

| Why is the areas around the deserts and tropics hotter than the areas around the equator? Posted: 14 Feb 2016 06:41 AM PST The Sahara Desert, for example, is located around Tropic of Cancer, and not the equator, and is still one of the hottest places on Earth. The insolation around the equator is also much higher, because of the way the Earth is bent. There's also a high pressure around the Tropics and low pressure around the equator. High pressure often have lower temperature than low pressure zones. [link] [comments]  |
| Would merging black holes without accretion disks produce a flash of light or other particles? Posted: 14 Feb 2016 06:18 PM PST Obviously inspired by the LIGO stuff. I'm asking because I see references to the "luminosity" of the merger, and I'm unclear as to whether that refers to the energy carried away in g-waves or whether energy was carried off in some other way as well. It seems unlikely, but it seems wild for there to be such a large energy release and have it be basically unnoticeable. [link] [comments]  |
| Has the Banach–Tarski paradox been generalized to higher dimensions? Can it be generalized? Posted: 15 Feb 2016 04:46 AM PST As I understand it, the Banach–Tarski paradox allows choosing an infinite number of points from a surface, such as a sphere, and by rotating and translating the points, reassemble a different surface, such as two copies of the original sphere or a larger sphere. Has this been generalized? Can it be generalized? Can an infinite selection of surfaces be reassembled into two copies of the original volume they're taken? [link] [comments]  |
| How are novel metabolite precursors identified? Posted: 14 Feb 2016 03:12 PM PST For example, if a scientist discovers a new metabolite, how do they begin building a metabolic pathway? I suppose radioactive tracers can be used to identify anything downstream, but how do they identify anything upstream of this new metabolite? [link] [comments]  |

| Did LIGO get incredibly lucky with two black holes colliding or are these fairly frequent? Posted: 14 Feb 2016 09:24 AM PST Also, Did we know this was going to happen beforehand? I understand how LIGO detected the gravity waves but how did we detect the merger in the first place? [link] [comments]  |
| Posted: 14 Feb 2016 03:29 PM PST If the part of the brain that processes the body part was never used because it was never there before, is there some way the brain will connect to the nerves in the newly grown structure and be able to process them, or will the body part be primarily for looks and function, not sensation?

| What would happen to a tachyon in a black hole? Posted: 14 Feb 2016 11:17 PM PST Since tachyons exist faster than the speed of light, would they be able to exit a black hole? [link] [comments]  |
