| What happened to all the anti-matter? Posted: 20 Sep 2018 03:55 AM PDT As per Physics...The amount of matter and antimatter produced or released after the big bang must be equal, then why is it so rare, and also how do scientists make it in the Large Haldron Collider? Is it possible that there is a whole another anti-universe or something?Why does it release tremendous amounts of energy when it comes into contact with matter? and one last thing...If anti-matter can give us tremendous amounts of energy, then matter also should be able to give the same tremendous amounts of energy when it contacts anti-matter in, say, an anti-matter planet or something, right? then that way if we find out a Place made out of anti-matter, then that'd be a great exchange for the aliens living there, and for us to give our normal matter and get some anti-matter, right? Fuel for us, fuel for them and we weigh not based on the item, but based on the mass. Or is it that matter out of a Diamond would release more energy when contacted with anti-matter than a banana peel? Just Curious. I hope all of it makes sense. Edit: Now it might make a little more sense(Punctuation xD) [link] [comments]  |

| Posted: 19 Sep 2018 09:33 AM PDT Hidden variables may not be impossible, but if they require a field that guides particles deterministically, shouldn't we be able to measure our movement through that field (the same way we should have been able to measure our movement through the luminiferous aether, if it existed)? Wouldn't that provide an absolute reference frame? I don't see how pilot wave theory can be made compatible with special relativity. Am I missing something? [link] [comments]  |

| Posted: 19 Sep 2018 11:32 AM PDT When winter camping many people like to stack two sleeping pads on top of each other. Normally, these pads have different r-values, one is usually inflatable with a high r-value, the other is made from Closed Cell Foam and has a lower r-value. Almost everyone agrees, the CCF sleeping pad should go below the inflatable. Other than protecting the inflatable from punctures, is there any science that explains why this way would be warmer?

| How do Islandic Spar crosshairs work? Posted: 19 Sep 2018 11:41 PM PDT I was wondering if anyone could tell.me how these islandic spar crosshairs that are described in the 'islandic alarm goes modern' section work. I have tried to replecate it but I feel that the classical blocks that are cut in a way that shows a nice double letter effect is not the right cut. Should it be cut allong a different axis? https://petapixel.com/2013/12/12/iceland-spar-rock-discovered-optics/ [link] [comments]  |

| What causes melted glass to appear orange / red hot instead of appearing transparent? Posted: 19 Sep 2018 08:30 PM PDT Just a random thought that came to my mind when thinking about the differences between ice and glass. I understand at a basic level that glass is composed of combinations of sand, soda ash, calcium carbonate, iron, chromium, and or plastic depending on the kind of glass being made, and when super heated it becomes this red-hot liquid. But when I contrast this mentally with water, or even plastic, I can't seem to understand why a similarly clear solid wouldn't melt into a clear liquid as well? I just can't seem to wrap my head around this; Is it a simple matter of one or more of the ingredients trapping light so well it gives off this color? Is it the unique structure of glass? Is it just the natural by-product of all that heating process giving off light? I appreciate any and all feedback in this, and bonus points for references and more reading material on this, as it's really caught my interest. Thanks! [link] [comments]  |

| How are we so sure that the Strong force only operates in small distances? Posted: 19 Sep 2018 05:08 PM PDT For example, we have the force of gravity and electromagnetic force. Even if we are maybe trillions of light years away from a source, you will still be never be 0, however infinitely close. But all I've ever heard was: "The strong force does not act on large distances" and I've been confused with that because for gravity and electricity, it still does at large and small distances. Does the strong force not obey the inverse square law? Is it some higher power than 2 so it diminishes quicker and we just just ignore it at a certain point? Do we not have a precise enough formula or understanding of the nature of the strong force so we just simplify it to "Just ignore it after this radius"? [Kind of like how we kind of ignore quantum mechanics after a certain distance(Planck) because our math does work out] Thank you! [link] [comments]  |
| Posted: 19 Sep 2018 12:52 PM PDT A friend of mine has a severe needle phobia and has for most of their life opted to get the nasal form of their yearly flu shot for this reason. And in discussing this we found ourselves wondering why this option wasn't available for other illnesses preventable by vaccination. Is it perhaps an issue of cost? Difficulty of adapting the formula? Reduced retention of immunity? Or perhaps some other factor or a combination of factors? [link] [comments]  |
| Posted: 19 Sep 2018 05:04 PM PDT Those elements could be americium (neptunium plus a deuteron or plutonium plus a proton/neutron), curium (plutonium plus a deuteron), berkelium (neptunium plus an alpha particle) and californium (plutonium plus an alpha particle). The reason neutrons, deuterons and alpha particles could work is because that giant amount of acceleration would cause the neutrons to split up on contact with the nucleus. [link] [comments]  |
