If you're referring to relativity, then it would be miniscule as in less than a second over a lifetime compared to those around you. Also, you would perceive your aging at your own rate. In other words, it is true as a very small difference that only others would be able to perceive. However, running or cycling will probably help you age more gracefully. In that sense, what you heard has some value.

Are you accounting for explosive/concussive force? I realize kinetic energy is one component, but a lot of damage is done in the explosives as well. I'm really not an expert; I was just throwing that out there.

If this wall was strong couldn't it form a "window" or "wall" of ionized air where objects could not pass through. Something like this. http://en.wikipedia.org/wiki/Plasma_window I'm not a scientist either, but I just thought I would mention this.

I concede my previous statement because it sounds asinine. I'm very sorry, I was tired at the time and it had been a long day. Spyman has the best response.

I'm fairly certain anything that is small and light can be swept up in air currents like dust. The bacteria and fungi make it there the same way. There was a past experiment questioning whether bacteria were made in the air or were falling through the atmosphere. I don't remember details, but I do know that the experiment proved that the bacteria must have been swept up. Moisture gets in by way of evaporation. Almost any amount of heat will allow small amounts of water molecules to be swept up into the air. As far as smell goes, there are many different explanations of varying depth. However, and overview would be that the particulates make it into the mucus and subsequently make it to the olfactory nerve fibers in your head.

From my somewhat limited understanding, I believe the current hypothesis proposes that the universe is like the earth in a sense. When they discovered that the universe was expanding equally in all directions it was postulated that the universe is flat but it curved into a sphere. It is like the earth because to us it appears flat, but it has a horizon. The 3rd dimension is in a sense pushed out of a 2 dimensional universe from the curvature. In short, you can always measure the distance between two points in the universe and always have a number less than infinity. However, the universe has not ending point. There is no empirical starting point and stopping point. This means that the universe may have a finite spatial area, but it doesn't have start or end. I'm pretty sure newer theories have come up since Carl Sagan's Cosmos. I jus thought I would throw in my two cents.

I would say highly unlikely. I can't say impossible, but I think the lack of heat and substantial atmosphere of any kind would make the formation of life highly unlikely. The moon's temperature might have been high enough to form cyanobacteria, but without an atmosphere this wouldn't work out.

I believe the reason planets exist on a similar plane has to do with gravity. The force of gravity and centrifugal force creates circular motion, and the general theory of relativity posits that we all exist on a universal plane. I guess that causes the planets to all orbit on a similar plane. I'm just a student, so feel free to correct me.

I'm pretty sure it will use your drive cache more so than RAM. Indexing the tracks will use RAM, so it will use some but not much RAM.

I doubt it would be easy, even if you travel often. I believe polyglots must be fluent and proficient in many languages, which requires hard study. It is difficult to become proficient in a language through osmosis. Think about English class; you have to take it even if you are a native. The same concept applies, and this means that simply traveling a lot won't make you a polyglot. However, if you truly enjoy languages, then being a polyglot can be great for finding jobs. Many jobs are always in need of employees who are multilingual. I myself speak Spanish fairly well, but that took quite a bit of study to accomplish.

I'm sorry, but what exactly do you mean by fusion or fission propulsion. These are methods for the production of energy. However, they won't produce thrust without another system. You could use them to produce power for an ion system, but you still need fuel. Fission reactors are not necessarily large though, NASA used small reactors for the Voyager probes I think. They weren't huge in spacecraft terms.

I don't think you could efficiently use magnets for that. If you want to make something with the apparent property of perpetual motion, then you can use temperature changes. The basic idea has two forks. In one version (this is used in "perpetual motion" clocks) utilizes temperature changes to move a spring. This allows you to have a clock that you do not have to wind. However, the concept basically only works for clocks, and the amount of energy rendered is minuscule. The other concept uses small temperature changes to vaporize a gas. This is slightly more effective because you can use a much better thermal conductor as long as it has a low viscosity. The basic concept is that you have a wheel with tanks filled with propane (I think) and a tub of water that the tanks dip into when they reach the bottom. The gas will remain in an evaporated state until it reaches the water. The water "sucks" the heat out from the gas and allows it to temporarily condense. This can make the wheel move very slowly without input.

My best guess would be that the constant yet somewhat difficult to explain expansion of the universe overcomes the gravitational pull between galaxies. This would be probable because of the vast distance already between galaxies. This prevents the galaxies from moving closely together and combining. Also, many galaxies contain black holes at the center. There is most likely a point at which the black holes has a negligible gravitational effect on the edges of the galaxy. However, I don't claim to be an expert.
