| How the heck did iguanas get all the way out to Fiji? Posted: 06 Apr 2017 06:02 PM PDT Iguanas are known from the Americas, nearby islands, and...Fiji and Tonga. Two islands in the middle of the Pacific, 10,000 km from the nearest other iguanas on the Galapagos. There aren't any iguanas known from any of the islands in between the two. There aren't any known from landmasses nearer to Fiji, like Australia and New Guinea. So what the heck? [link] [comments]  |
| Posted: 07 Apr 2017 01:25 AM PDT It seems that these objects must swap material since we have already seen geysers. I feel like if any of them have life then probably they all do [link] [comments]  |
| What would be the implications of finding the hypothetical tachyon particle/ tachyon field? Posted: 06 Apr 2017 08:23 AM PDT I've read somewhere that if such a particle/field existed where the particle would travel faster than light, then causality would be broken. If this is the case, why does that matter and what would the implications on physics be if such a phenomenon was discovered? Thanks! [link] [comments]  |

| Posted: 07 Apr 2017 02:54 AM PDT Also, if this effect is negligible on the earth, are there any closer planets to the sun which this is a bigger factor on? [link] [comments]  |
| If a nearby star goes supernova, what are the consequences in our solar system? Posted: 06 Apr 2017 06:28 PM PDT Wikipedia said if Alpha Scorpii A does, the light could be as bright as the moon. That seems like other things would be going on as well if it's that's significant. [link] [comments]  |
| Is "10" in binary pronounced "two" or "ten" ? Posted: 07 Apr 2017 07:35 AM PDT Instinctively i'd be inclined to say "ten", but then I thought about the word two and whether it refers to the notation "2" or the value "two units". Logically it would be two units, I mean counting can exist even without written notations. Therefore "10" in binary representing two units should be pronounced "two". But I'm still uncertain, it raises even more questions like whether A in hex is pronounced "ten" or "ay"... Is there even any definitive answer ? [link] [comments]  |
| Why can the sum of two cubes never be prime, but the sum of two squares can? Posted: 07 Apr 2017 07:20 AM PDT 1 is the only number that gives you a prime from what I've found, because 13 + 13 = 2. Im pretty sure the sum of two numbers that are both to an odd power can never be prime, but im not sure. Is there a proof for this? [link] [comments]  |
| How are vaccines developed 20+ years ago still effective in combating always-mutating bacteria? Posted: 06 Apr 2017 06:07 PM PDT If a bacteria can change to avoid eradication over the course of a 7 to 10 day administration of antibiotics, how does a vaccine developed in the 90s against one strain of bacteria still prove effective?

| Why does consuming energy always produce heat? Posted: 06 Apr 2017 10:00 PM PDT Computer Processors, Car engines, it seems consuming energy always produces heat. why? Why can't a computer processor just, not make heat? Is there like an opposite that produces cold instead? [link] [comments]  |
| Theoretically speaking, could antimatter be contained and stored? Posted: 06 Apr 2017 04:57 PM PDT My understanding of antimatter is limited, but what I do know is that if antimatter meets regular matter then they destroy each other. With that in mind, is it possible in theory for antimatter to be stored? For example, a chunk of antimatter suspended in a vacuum by a magnetic field. I imagine it would take a lot of power and technology we're nowhere close to now, but is it possible? I've seen antimatter used as weapons in a few sci-fi stories so it got me curious about how it would be stored/manufactured. [link] [comments]  |

| Is there a second complex plane? Posted: 06 Apr 2017 02:42 PM PDT Does there exist another "complex" plane? Two analogies to explain what I mean:

| What is the penetrative power of an atom in a particle accelerator? Posted: 06 Apr 2017 08:39 AM PDT If you lined up as many humans as you could inside a particle accelerator, how many humans could the atom go through until it stopped? [link] [comments]  |

| Is it by coincidence that we consider North as "up" on maps and globes? Posted: 06 Apr 2017 06:14 PM PDT Is there an astrological or geological reason that we usually consider North as up on a map? Did an early cartographer just consider that they were in the upper hemisphere of Earth, and drew it like that, so it became the norm? I think it's interesting that if we drew the maps the other way around, then the Earth's spin and orbits would be in the opposite direction Also, as a follow up, why does it seem that there is more land mass in the Northern hemisphere? Is it coincidence? [link] [comments]  |
| So why does your body get sore when you're sick? Posted: 06 Apr 2017 06:54 PM PDT Hey guys! So I've got a nasty cold I'm battling over here and my back absolutely aches! So here's my question: why does the body get sore and ache when you become sick? [link] [comments]  |
