I like the way that explains the lack of anti-matter. But really I do not have the education to make any intelligent comments on this.

I believe it superheats water in the rock that causes the explosion. Thats what caused that huge explosion in siberia in the early 1900s. I'll look for a link. edit: ah, here we are: http://en.wikipedia.org/wiki/Tunguska_event

How does a brain scan allow for lie detection, I've never heard of this. Polygraphs do work, they are not a scam. They just dont always work. You can train youself in various ways to cheat a polygraph. Falsy accusing someone is trickier. They always start with questions such as "what is your name" "what are your parents names" and stuff like that. Basically they start with very easy questions, so they know what sort of readings you give when you tell the truth. When you ask something that makes a person nervous, you get higher readings. When the person lies, you get extremely high readings. The question is, where is the line between nervousness and lying? This is why lie detectors are opperated by humans, so they can judge the responses.

All the nukes in the world detonated at the same time would produce and insignifigant signal on astronomical scales. Plus it would probably look just like all the other stars around. You have to use a frequency or entirely different method where there is going to be less natural interference.

Hmm, I thought that mass really did increase with velocity. I guess I learned something new today.

Inertia - throwing a ball off of a moving train
[Tycho?] replied to themad2's topic in Modern and Theoretical Physics
Well the ball stops in the same way the train would stop, if it hit something. When you throw the ball from the train the ball is still moving at 70mph compared to the ground, so it will hit the ground moving at that speed. edit: I neglected to read the part where he threw it off the back at the same speed. Yes it would go to zero and drop, sorry about that. -
Man, imperial system is rough. Metric is so much easier.

Temperature has no bearing on gravity to the best of my knowledge.
-
Well you can figure it out using conservation of momentum, but then you'd have to know the mass of the wall. mv=mv, and you can assume the mass comes to a complete stop, then find the velocity of the wall. This equation doesn't look familiar, although I can't think of a reason it wont work for rudamentery purposes. if you want the energy released in such a reaction you can find the kenetic energy. That is E=1/2mv^2. Where m is mass in kg and v is velocity in m/s, and E is energy in Joules.

It works because the twins are not in the same inertial frame. Frames of refference are equally valid only when they are in the same inertial frame. Since one of the twins is accelarating, they are not in the same intertial frame. Here is a detailed article on why this works. http://en.wikipedia.org/wiki/Twin_paradox

Well for one thing, time dilation has been proven. It must be taken into account when programming and using GPS satellites. They move fast enough that there is an ever so slight effect. If we didn't compensate for this effect, GPS systems would be innacurate by several hundred meters or more. Otherwise, I'm not really sure the point you are making. So I'm just going to say something that may help- remember that c is contasnt. Moving into a light beam, moving at right angles to it, moving away from the light beam, it always seems to be moving at the same speed. I dont know if this has any relevance at all to what you said.

Hahaha, I like how the first post is asking it like he wants to build a tesla coil or some other home project. You would need several million dollars anyway. You need a launch site. You need to design your rocket, and so you need a ton of knowlege in engineering, math and physics. You need to fuel it. You need to have some sort of guidance system. And you need to make it legal somehow, which you wouldn't. There's no way governments are going to tolerate random people throwing crap into orbit. What if you shot something at the ISS?
-
Yeah I was going to mention that super-high balloon jump as well. The trick is terminal veloctiy. Just because you are falling from space doesn't mean you are moving at rediculously high speeds. If you are stationary relative to the atmosphere you are falling into, I'd think you'd be able to do it with no need for heat shields. You would need specially designed parachutes I would think, since you do get moving pretty fast (the record holder broke the sound barrier I think, this is possible because the atmosphere was so thin up there).
-
Yup. It is a barrier because it would require infinite amounts of energy to accelerate to c. It would be a pretty strange physical wall, one that is all pervasive and not normally detectable.

I did a brief check, got this: http://www.physlink.com/Education/AskExperts/ae191.cfm If you do a google search for "electron size" you get numerous results with your exact question being asked. Also, it is not know if the electron is truely a point particle, only that its smaller than we can measure, and it can be treated as a point for experimental purposes.

High Density Plasma Toroid Fusion
[Tycho?] replied to Erich's topic in Modern and Theoretical Physics
You asked if we could provide assistance... but with what? There are only a few people here with actually detailed and reliable knowledge (I am certainly not one of those), but this seems like a rather specific topic, that requires specific information that is obtained through research. This is all very interesting, but I'm not sure how much help you are actually going to recieve at a place like this. -
I'd say cut out most if not all of the human missions. Unmanned probes can usually accomplish the same task at a fraction of the cost and time.

If the moon hit earth we would have larger problems than changes in earths orbit. That impact would completely shatter the earths crust on the side of the planet that it hit. It would probably severely damage it over the rest of the earth, creating gaping holes from which magma could flow forth. All the landmasses on earth would have to be completely reformed after that point. The oceans would probably all be boiled away, they atmosphere would increase in density by a good amount by the amount of dirt sprayed into it. All organic life would be totally incinerated, suffocated, and then buried by lava. I highly doubt any life at all would survive the initial impact.

lol. If creating a gravitational field is not artificial gravity, then what is it exactly?
