| Why does catnip have such an intoxicating effect on cats and do we know what they're experiencing? Posted: 29 Jun 2017 07:38 PM PDT I just watched my cat have a catnip trip and I wanted to know what it was like for her and how it happens [link] [comments]  |
| What happens when lightning strikes in an ocean? Posted: 29 Jun 2017 09:05 AM PDT Knowing that water is a conductor (and salt too?) how far would an electric current be carried through an ocean? Would the electricity just fizzle out after a certain distance or would it keep traveling until it hit an insulator? [link] [comments]  |

| Posted: 29 Jun 2017 08:04 AM PDT Here is a picture of Falcon-9 and Ariane 5. As you can see there don't seem to be any apparent fins on either of the rockets. So how do these rockets remain so stable? [link] [comments]  |

| Posted: 29 Jun 2017 08:31 PM PDT I have a some more questions that extend from this main question and I just want to know as much as I can. What causes them? Why can I clearly remember some and others not at all? Why can I control some and others my mind is tricked even if stuff makes no sense? Why can you have nightmares? Thank you for any replies.

| Could we create a space Crane on the moon? Posted: 30 Jun 2017 04:30 AM PDT I know that currently we do not have the materials to create a tether that can run from the earth to space to create a space elevator. Could we do it on the moon? [link] [comments]  |
| How does diet affect the risk of heart disease? Posted: 30 Jun 2017 08:15 AM PDT There is a lot of conflicting information out there. The common story is that (saturated) fat and cholesterol in meats are the primary culprits, but now a lot of (pop) science seems to claim that those are relatively harmless and sugars are instead the main culprits. What does the actual scientific evidence support? [link] [comments]  |
| Posted: 30 Jun 2017 04:29 AM PDT Is artificial intelligence a computer or something else? Stated differently, could you have a regular computer one day like an iPhone, then the next day get nothing more than a software update and have AI on the same phone? Or would there need to be different hardware installed? [link] [comments]  |
| Posted: 29 Jun 2017 07:26 PM PDT Let's say I'm on an earthlike planet orbiting Proxima Centuri or some other close star... what would I need to pick up TV or Radio signals? [link] [comments]  |
| Posted: 30 Jun 2017 02:25 AM PDT I'm making a couple of assumptions in my question - namely that we can move water to the hole in a steady consistent fashion and that we can build a steam turbine at the hole or close enough to the production of steam to be useful. I don't know if the water would eventually cool down the heat source. I just think about underwater magma and how that seems to continuously flow. [link] [comments]  |
| Posted: 29 Jun 2017 09:56 AM PDT If I understand the theory correctly, all distant galaxies are sitting still in space essentially motionless with respect to the Milky Way and this has been the case ever since the moment of the Big Bang. Distances are increasing between distant objects but nothing is in motion. That is why we have concepts like cosmological red shift (caused by the universe expanding and NOT by motion) and the Co-moving coordinate system which depicts the universe as essentially static. Am I missing something? I know that there is never zero motion. However, on the scale of the universe the motions of stars in a galaxy or galaxies in a cluster are like the motions of atoms within a diamond (or not?) The atoms are moving but the diamond is static and you could use atoms in a massive diamond to map the galaxies in the universe with an equal amount of relative motion. Is there some motion involved with the Big Bang and the expansion of the universe that I don't know about? Is there something in the universe actually moving due to these effects in such a way as to have relative velocity to something else in the universe? I know that the Big Bang and the Expansion of the Universe made room for the 4 forces to work in but motions like the orbits of stars in galaxies are caused by gravity not the expansion of the universe (right?) The Big Bang and the Expansion of the Universe seem to be described using action words in all the videos I can find. Nowhere does it describe a silent, frozen, universe. However, cosmological red shift and the co-moving coordinate system seem like concepts invented to describe a static universe experiencing a metric expansion of space. Please help me understand what is going on. [link] [comments]  |

| What is going on in your brain when you're unconscious? Posted: 29 Jun 2017 08:17 PM PDT Also, are there different levels of unconsciousness? [link] [comments]  |

| Posted: 29 Jun 2017 07:06 PM PDT I asked a friend and he said it was probably because our body's muscles get tired and need to rest, but I didn't think this was right as we can just eat food to give us energy. [link] [comments]  |
