| Posted: 24 Nov 2019 05:26 AM PST I know that lapse rate is defined as the decrease in temperature as height (elevation) increases. So what is an increase in temperature as elevation decreases called? For some reason extensive searching has not yielded me anything yet. [link] [comments]  |
| will a nuclear bomb produced 20 or 30 years ago still detonate as it is planned? Posted: 24 Nov 2019 04:53 AM PST i always wondered what would happen if you deploy a nuclear bomb produced long time ago. obviously nobody has ever tried this so it all very theoretical. to get full force all components have to be very precisely calibrated but nuclear materials decay with time. is there a chance that it will go off but just create a lot of pollution without proper detonation? are the active materials supposed to be renewed once in a while? if so is anybody is doing this in reality?

| Posted: 24 Nov 2019 04:22 AM PST If the latter, what does the distribution look like as it is shifting and how long does it take? [link] [comments]  |
| What exactly is color superconductivity? Posted: 24 Nov 2019 04:02 AM PST I've googled it, but I'm having a hard time visualizing what exactly happens. [link] [comments]  |
| Is it possible for asteroids to contain incredibly huge gemstone cores? Posted: 23 Nov 2019 10:01 AM PST Im not familiar with the conditions required for precious stones to form, I know diamonds require a lot of pressure for the crystal structure to take form but not much else, could the conditions in an asteroid belt allow for lets say an emerald geode with a diameter in the dozens of meters? Also I see this sub doesnt consider geology a real science, really funny guys, bazinga... [link] [comments]  |
| Can Carbon Dioxide exist as a liquid? Posted: 23 Nov 2019 08:57 AM PST I understand that carbon dioxide can deposite as dry ice, and sublimate back to a gas, but can it melt or condense into a liquid? Is any place that carbon dioxide can be found naturally as a liquid, or is it only possible through artificial processes? [link] [comments]  |
| Did the gauge bosons, from before the fundamental force separated into four, persist? Posted: 23 Nov 2019 12:34 PM PST When the fundamental forces were unified they had different gauge bosons, such as the W1, W2, W3, and B particle for the electroweak force. All of which are massless and therefore stable. Would any of them have survived the separation of the fundamental forces? [link] [comments]  |
| I’ve heard that quantum computers can break encryption easily, why? Posted: 23 Nov 2019 08:21 AM PST You can assume that I've a 101 level understanding of AES and Qbits. [link] [comments]  |
| Are we living in on higher ground than people in the past? Posted: 23 Nov 2019 05:06 PM PST As i was watching some documentaries, i saw some pattern. All these ancient buildings beneath the ground completely buried ( for example giza pyramid, moai heads, gobeklitepe) or cities being under sea. It is certain that sea levels changed all the time during earth's life. So these buildings were not buried by someone but earth itself. So layer upon layer, earth in the air, or carried from somewhere else or from volcanic eruption just fills this land and we think that it was always this high. [link] [comments]  |
| How common are induced earthquakes? Posted: 23 Nov 2019 04:04 PM PST I've heard that humans can induce earthquakes through mining activity and fracking (although usually not enough to be felt) but I haven't been able to find any information on how much of all earthquakes worldwide are induced.

| Is it possible to use a audio port to transmit data to a usb (bear with me I’ll explain it)? Posted: 23 Nov 2019 09:09 AM PST So basically could you theoretically hook up the right sound to data in, microphone to data out, a battery or something for a power source and some crazy stuff with audio drivers/usb drivers to receive and transmit data through the audio jack. Idk it sound hypothetically possible I just feel like it would've been done by some hobbyist already. [link] [comments]  |

| How do various sea creatures know when they have swum as deep as is safe for them? Posted: 22 Nov 2019 08:11 PM PST Animals live at various depths of water. Some stay closer to the surface. Some stay on the sea floor. What about the ones that swim to different depths? How do they know what their "comfort zone" is and that they are about to leave it? [link] [comments]  |
