| Posted: 12 Jan 2016 05:56 AM PST I have always had the impression that either general relativity is wrong or our current standard model is wrong. If our standard model seems to be holding up to all of our experiments and then we find strong evidence of gravitational waves, where would we go from there? [link] [4 comments]  |

| Can light, specifically visible light, destructively interfere? Posted: 12 Jan 2016 06:14 AM PST Sound waves can destructively interfere, so what about light? (Or gravity for that matter, since we /may/ have discovered gravity waves.) Is it possible for light waves to destructively interfere and cancel out the light? [link] [8 comments]  |
| Posted: 12 Jan 2016 06:06 AM PST This question was asked here and the popular answer is that the downward pressure from the bird's wing would push against the floor of the plane and have the same effect as if the bird were standing on the floor. I argue that this pressure would mostly dissipate before reaching the floor and have minimal effect, and that the lift created by the bird's wing would nullify any effect it had on the weight of the plane. Any thoughts on this? [link] [8 comments]  |
| Can someone explain the Bell Test Experiments? Posted: 12 Jan 2016 03:32 AM PST Hi! My knowledge reaches a wall at a certain point. At the moment, my understanding is that, Bell performed an experiment to test if entangled elements were determined to look a certain way since the entaglement, and not a probability. For example, if we observed a spin-up particle, we knew for sure that the "partner" would be "spin-down".. [link] [comment]  |
| What happens to Oceanic crust once it passes the Moho during subduction? Posted: 11 Jan 2016 02:59 PM PST In many of my upper level Geology classes, the professor can not answer the question. Nobody knows exactly what happens to the crust, whether it eventually all melts and diffuses into the mantle or if it makes it all the way to the outer core, to be melted there. Any thoughts?

| How does matter turn into energy? Posted: 11 Jan 2016 03:33 PM PST Wouldn't this imply at some point in time a particle goes from having mass to having no mass. The time it takes from going from some mass to zero mass must be finite surely? or is it something that occurs within planck time or just within the bounds of the uncertainty principle? a mass can't just go from non-zero to zero , because it would imply having some kind of acceleration and massive objects can't just go to the speed of light at the flick of switch. So what is the process? do we know or is it just a kind of black box scenario. Even something like fusion, does that imply two hydrogen atoms fuse, do the gluons in the reaction just not end up in the reaction not make mass and gluons just 'fly away' as a gamma ray burst or something high energy?

| What causes certain molecules to form dipoles? Posted: 11 Jan 2016 05:46 PM PST Why does H2O not form a straight line to avoid having strange charges? [link] [4 comments]  |
| Can there be such a distance function? Posted: 11 Jan 2016 10:24 AM PST I want to know about a special distance function. I know the properties of a normal distance function, in any space, but one has recently drawn my attention: the triangular inequality. The triangular inequality can be explained the following manner (if I understand correctly): given A,B and C 3 points in some space and D a distance function in this space, than the following statement is true: D(A,B) <= D(A,C) + D(C,B). My question is: can there be a distance function for which the following statement is true: given A,B and C 3 different points then D(A,B) < D(A,C) + D(C,B)? If yes, which one, how? If no, why? Edit: Thanks everyone for the answer. I didn't realize so weird distances and metrics can be useful, I just thought it is a weird question to think about. Well, you learns something everyday!

| Do you think particle entanglement would enable scientists to "see" into black holes? Posted: 11 Jan 2016 09:07 PM PST Because theoretically we could beam entangled particles at high speed to scan things from far away. Sounds cool, but is it feasible? [link] [7 comments]  |
| What is the possibility of the current fracking in Northern BC causing catastrophic damage? Posted: 11 Jan 2016 05:08 AM PST Just heard that the earthquakes are growing stronger the latest being 4.8, what is the possibility of the fracking to get to a catastrophic level? If they do decide to stop fracking, would the earthquakes continue to grow or would they stop? What kind of fallout can we except for the current direction of the fracking happening?

| Why is the egg yoke in the center of the egg when you hard boil it? Posted: 11 Jan 2016 06:16 AM PST If you open a raw egg, the yoke and white part are different consistencies, and I assume different densities. Why does the yoke float right in the middle when the egg is hard-boiled instead of rising to the top or falling to the bottom of the egg? Even if the yoke and white part have the same densities, wouldn't the yoke have just as good of chance at being along the top, bottom, or sides? Every hard-boiled egg that I've seen has the yoke right in the middle. [link] [10 comments]  |
