| What are the limits of gravitational slingshot acceleration? Posted: 23 Jul 2018 09:59 AM PDT If I have a spaceship with no humans aboard, is there a theoretical maximum speed that I could eventually get to by slingshotting around one star to the next? Does slingshotting "stop working" when you get to a certain speed? Or could one theoretically get to a reasonable fraction of the speed of light? [link] [comments]  |
| Does a knee-jerk reflex happen while under anesthesia? Posted: 23 Jul 2018 08:55 PM PDT Why or why not, and why would/wouldn't it happen while other functions continue? [link] [comments]  |
| Is there a limit on how sticky something can be? Posted: 23 Jul 2018 07:38 PM PDT Flypaper and mouse glue traps are super sticky bind on contact substances. Is there a limit to how sticky things like this can get? [link] [comments]  |

| How do relativistic effects affect planetary orbits? Posted: 23 Jul 2018 10:44 AM PDT I imagine its just some tiny little correction, but I'm curious about order of magnitude how large that correction is and qualitatively what its effects are. [link] [comments]  |
| What causes the shape of pilot wave in quantum mechanics? Posted: 24 Jul 2018 04:46 AM PDT I can not picture the definition of the "event" that caused pilot wave's shape exactly in my head. Is it about fabric of space-time? Is it because of gravity? or something else that we don't know yet? what causes the "randomness" of the wave? [link] [comments]  |
| How do we know about dinosaurs soft tissue morphology through fossils? Posted: 24 Jul 2018 07:20 AM PDT How do we know about a dinosaur soft tissue shape? how do we know how big are their muscles just by looking at their bones, and how sure are we about it? are we rolling with the best chance, or do we have any clue about how it worked?

| What is the likelihood that the key to my house is also a key to a lock I don't know exists? Posted: 23 Jul 2018 10:55 AM PDT There can only be so many variations on a key, right? So what's the likelihood that the key I have to open my house is also a key to something completely different, like a shed in Ireland, or a bike lock in Japan? I know this isn't too science-y, I just kinda wanted to know, and there's no "AskStatisticians" that I could go to. [link] [comments]  |
| Why do halons do more damage to the ozone layer compared to CFCs? Posted: 24 Jul 2018 06:17 AM PDT How does the bromine free radical do more damage compared to chlorine free radicals? Do all the halogens in an haloalkane become free radicals? Follow up question: what about similar molecules containing iodine/ other halogens? [link] [comments]  |

| Posted: 23 Jul 2018 08:34 PM PDT I'm curious about whether the decrease in carbon dioxide has been an advantage for us in the way that eating meat might have given us more energy to work with, and I'm wondering if an increase in atmospheric co2 might hinder us, evolutionarily, in the future.

| Is There Infinite Matter in the Universe? Posted: 23 Jul 2018 11:12 AM PDT We believe that the universe is infinitely big, does that mean there is an infinite amount of matter in the universe or just space? [link] [comments]  |
| How do you calculate the density gradient in a salt solution? Posted: 23 Jul 2018 07:36 PM PDT For example how do you find out how dense the top is from the middle and the bottom ? [link] [comments]  |
| Stars near the center of the universe, how much longer has time "felt" do to moving slower? Posted: 24 Jul 2018 05:08 AM PDT Another way of framing the question for clarity:How much faster do the galaxies at the expanding edge of the universe travel, and how much does the relativity of time change from there to slower parts of the universe?

| Does the time flow different on Earth than it flows on other planets in our Sol system? Posted: 23 Jul 2018 11:14 AM PDT I've been reading Scott Orson Card's books recently and the dependence of the time from our speed is a very pointed phenomenon. Can we measure the difference of how fast time passes between a person on Earth and a person on other Solar System planet, that moves quicker / slower? If the difference is too small, what with a body that doesn't move at all? Edit 1: Missclicked "ee" instead of "we" [link] [comments]  |

| What is Cobalt effect in the testing of Oxygen Transfer Rate (OTR) of a membrane? Posted: 24 Jul 2018 12:16 AM PDT In the testing of Oxygen Transfer Rate of a membrane using the sulfite-oxidation method, excessive cobalt as a catalyst can result in cobalt effect. However what does "cobalt effect" really mean and how does it affect the test in any ways if any? [link] [comments]  |
| Do other species of pigeons (besides the rock dove) have a homing instinct? Posted: 23 Jul 2018 02:56 PM PDT If not, what is different between rock doves and other pigeons that creates the homing instinct? [link] [comments]  |
