4784Could I have a bag of neutrons? And if so, what would it look like, would they be reactive?
3853Do electrical cables have a jerk effect, similar to a water hose, would the voltage/throughput matter?
241AskScience AMA Series: I am Jessica Pierce, a bioethicist who has recently focused my work on animals. AMA!
11Why do we refer to radio frequencies in terms of frequency, not wavelength? We refer to everything from IR to UV in wavelength, and media from before the 50's or so tends to use wavelength. Why did we switch?
18Does there exist a dielectric that would lower the capacitance between two plates instead of raise it?
2[chemistry] Do electrons ever switch places within the same atom?
29Why are the oceans salty and where does the oceans salt com from?
4Why don't electrons all fly off their orbits considering how much energy is present in everyday contexts?
3Does the rotation of the earth's magnetic field (either around the poles or around the sun) generate an electric field?
6Why are the bottom of clouds flat? Or at least appear to be flat?
8173We’ve now discovered that spending a year in space can change your DNA - What does this change about what we thought we knew about DNA?
3Some ants cultivate fungus for food and use pieces to start new gardens. Do their cultivated fungus have evolutionary differences to their wild counterparts?
0If photon of light does not have mass, how it be affected by gravity?
31What is a Lagrangian? What is the action? Why does the principle of least (stationary) action work?
1Do supernovas make noise? If so how loud?
4Bosons have integer spin (such as 1, 2 or 3) whereas fermions have half-integer spin (such as 1/2, -1/2, 3/2, 5/2). In what situation does a boson have for instance spin 3, and a fermion spin 3/2?
4What does Particle Horizon growth mean to observer?
2How uniformly are the metals in an alloy distributed?
5348At what point in human evolution did we develop a dominant hand? Is this a trait found in other primates as well?
50Since neutrinos DO interact with particles if they get lucky, such as atomic nuclei, do neutrinos interact with the strong force, or weak force?
55Is it possible that we could discover some place deeper than Challenger's Deep?
110Does using a graphics card create "wear and tear" on the GPU?
4Would the impact of a very big meteor like the one causing the dinosaurs extinction be noticeable around the world?
51What prevents carbon from forming four bonds with another carbon atom?
1How exactly do wireless phone chargers work?
10Is there anything that won't be a solid at absolute zero?
1How long does it take for a new island to get colonised by plant and animal life?
7Does the depth of a body of water affect its surface tension? Why or why not?
5How many atoms are being split in an atomic bomb? What would happen if they did a bunch of them (like 5x the amount or more) Would it have any effect on the size of the explosion?
46If someone is paralyzed from the neck down, how can they still breathe or have a heartbeat?
6Can low energy beta radiation emitted from a tritium vial damage plant seeds?
11NASA's Kepler Space Telescope is running out of fuel. What type of fuel does it use and why does it need it?
4Do sunspots have antipodal sunspots?
8Why are observatories on hills and mountains? Does this extra height help?
2Has there been any recent breakthroughs in monopole particle research? Is it possible to use a monopole particle as a catalyst for proton decay?
65450Stephen Hawking megathread
2When transmitting RF, how do electrically long and electrically short lines affect your transmission?
13Why don't the protons in the nucleus repel each other like positive magnets?
59What is the hiccup actually doing? Is the function trying to accomplish something, or is it just an alert to drink water? Or is it something entirely different?
5If a plant was unable to build a proton gradient in the chloroplast, I know it wouldn't be able to produce ATP. Would it still be able to produce NADPH?
