| Posted: 07 Apr 2018 07:42 AM PDT The higher you go, the greater the chance of finding a non prime, right? Multiples of existing primes make new primes rarer. It is possible that there is a limited number of prime numbers? If not, how can we know for certain? [link] [comments]  |
| Posted: 08 Apr 2018 04:34 AM PDT I have read a bit about Helium-4 and it seems that the cancellation of the intrinsic spins of the particles of 4He makes the atom a boson which is a requirement for a superfluid. So if atoms behave like bosons there will not be binding forces between them? Also, is it the atmospheric pressure that keeps a superfluid in liquid phase? Since there is no cohesion I would expect it to evaporate in a vacuum. [link] [comments]  |

| How much consideration did astronauts of the Apollo missions give to debris? Posted: 07 Apr 2018 11:54 PM PDT I know the moon has had billions of years to collect it's craters, but how much concern did NASA have of a collision with rock impacting the surface of the moon or their spacecraft on their way? I'm just curious since there is no atmosphere to burn the meteors before they hit the surface, and the moon has so many craters. [link] [comments]  |

| How do scientists know which atoms make up a certain substance? Posted: 07 Apr 2018 06:18 PM PDT E.g., how do we know water is made of 2 atoms of hydrogen and 1 atom of oxygen? [link] [comments]  |

| Is there a limit to how far we can ‘zoom in’ on something? Posted: 07 Apr 2018 11:02 PM PDT Just curious if there is some kind of barrier preventing us from zooming in extremely close to something at very far distances. For example would it be possible to zoom in and see a single atom on the moon from the Earth. How far can we physically zoom in and what would the limit look like if there is one?

| How do natural hot springs work? Posted: 07 Apr 2018 09:25 PM PDT I took my first trip to Colorado and I went to the natural hot springs in Glenwood Springs. They had about 10 pools and each small pool's temperature was self regulated and varied throughout the facility. How is this possible/where does the natural heat come from? [link] [comments]  |

| Posted: 07 Apr 2018 05:55 PM PDT I always see beautiful images of galaxies, with their spirals and patterns and their overall cohesive shapes, but they seem to be against a backdrop of black nothingness. Is this nothingness real? Are there rogue planets or solar systems there? Is it just floating clouds of dust? Or do the edges of galaxies rub against each other? Do galaxies drift around? Does two galaxies touching mean they'll eventually collapse into each other? [link] [comments]  |
| What is the lower limit of the number of cells that can make up a multi-celled organism? Posted: 07 Apr 2018 05:27 PM PDT Often, I see discussions on how many cells the largest organisms have, but I have yet to come across an answer on what the lower limit is in regards to cell count. Am I over-thinking this and the answer is simply two? What kinds of factors play into how many cells or the interactions between cells that make something a multi-celled organism as opposed to a small colony of single-celled organisms? Thanks for helping me out. [link] [comments]  |

| Would the formation of fossil fuels (coal, oil, gas etc) be a rare phenomenon on other planets? Posted: 07 Apr 2018 02:14 PM PDT The advancement of the human race seems to be closely related to the exploitation of these resources (for example coal for the Iron Age and still used today) and wondering how the availability of it would affect the rise of life forms on other planets [link] [comments]  |
| Why doesn't air just fall to the ground due to gravity? Posted: 07 Apr 2018 11:09 PM PDT I know that gasses are supposed to expand to fill up a space, is that Why? But then why do they do that, and seemingly defy gravity? [link] [comments]  |
| Do the poles receive more cloud coverage than other regions of earth? Posted: 07 Apr 2018 04:08 PM PDT In most depictions of arctic or Antarctic explorations it seems super cloudy/snowy. Is this accurate, and if so why? [link] [comments]  |
| How do they manage to keep track of Voyager 1 ? Posted: 07 Apr 2018 11:58 AM PDT Hi, I am in intrigued on what do they have to consider to know precisely the location of the space probe since it is so far away from us. Thank you [link] [comments]  |
