| Is there any way to prove that all points on the number line correspond to a real number? Posted: 01 Apr 2018 09:57 PM PDT And vice versa (that all real numbers have a unique spot on the number line)? If so, what is it? I've noticed that this is something I've been assuming for a while. I was wondering if this is just a convenient shorthand or if there is a rigorous connection. [link] [comments]  |

| Are chewable vitamins more easily absorbed by the body than “pill” vitamins? Posted: 02 Apr 2018 05:01 AM PDT My friend told me that chewable are more easily absorbed by the body. Is that true? [link] [comments]  |

| Do all stars have the same photospheric composition? Posted: 01 Apr 2018 07:33 PM PDT I googled this question and only received vaguely related articles and blog posts. I would assume the photospheric composition of a star changes whit the different stages of a stars life cycle (O to M classes) but I would like to know for sure rather than accept false information.

| Do we have satellites around other celestial bodies? Posted: 01 Apr 2018 11:44 AM PDT I've always wondered. We do fly-bys with probes, but why not just park an imaging satalite above, say, Jupiter so we can monitor it and its moons for years? Or do we already have something like that? [link] [comments]  |

| Which would burn more calories by: running a mile, walking a mile, or are they the same? Posted: 01 Apr 2018 01:14 PM PDT I think this may boil down to a biomechanics problem and is probably affected by running and walking form. If that's the case, you can assume the most energy-efficient walking and running form. [link] [comments]  |
| How does the size of a proton change under different conditions? Posted: 01 Apr 2018 03:14 PM PDT Within different sizes of atomic nuclei what governs changes in the size of the proton? What conjecture is there? What do we know? And how does this affect the density of atomic nuclei? If any astrophysics people know anything about say matter in extreme conditions and it's affect on size that would be interesting to hear as well. [link] [comments]  |
| What is the difference between freeze-out and decoupling? Posted: 01 Apr 2018 11:47 PM PDT I've been trying to figure out what the difference between freeze-out and decoupling is with the help of books and google, however I've not been able to come up with anything useful - most everyone equates the terms but that begs the question why there exist such different terms. As I understand it, decoupling means that the particle class we speak of is no longer in thermal equilibrium with it's surroundings. Thus the universe become transparent and they propagate freely from then on - not interacting with the rest. Freeze out means that the particle abundance becomes constant - i.e. there is no more interaction with the rest and equilibrium is left behind. Are my understandings of freeze-out and decoupling right? And what then is the difference between the two? [link] [comments]  |
| What does it mean that "the electromagnetic force is carried by photons"? Posted: 01 Apr 2018 09:18 AM PDT So I kind of sort of understand what a force carrier is, and I know that photons are the force carrier for the electromagnetic force. But what does that mean, exactly? When I put two magnets together, they don't emit light or anything, and particles can't pull things together, only push them apart. So what role do photons play in this interaction? And I'd assume that photons are also to blame when it comes to positively charged particles attracting negatively charged particles, but how does that work? Again, particles fired toward another particle should only be able to push them apart, right? So how exactly does the exchange of photons keep charged particles together? And lastly, what about when magnet poles or like-charged particles get close together? I'd assume in this case, photons exchanged between the two objects would push them apart, but why don't we see any visible light when this occurs? [link] [comments]  |
| Does the moon/sun's gravitational pull affect how high I can jump height on earth? Posted: 01 Apr 2018 01:15 PM PDT The moon and sun have effects on gravity on earth, which can be seen with the tides, human physiology, and more. My question is if the pull of the moon and sun have enough of an effect on the gravitational acceleration here on earth that I could be able to jump slightly higher when the moon/sun are overhead than when the moon/sun are underneath us?
