Physics - July 2006

If you took the most powerful laser in the world (I believe it is located at Lawrence Livermore National Laboratory, and is rated well into terawatts) and fired it at a target for, say, a fraction of a second, and then if you could get an average cloud-to-ground lightning bolt to hit a target for the same time interval, which would generate the most power?
Single lightning bolts have been rated well into millions of volts, but how would that compare to the energy of a laser beam, since laser beams are mass-less photos while lighting is made up of charged particles?

well, for ever effect this has of sounding nuts. i want to ascend to a higher level of existence. i do not know what it is, do not know if it is possible and if it is how to do it. i want to approach this scientifically through quantum physics and other related sciences and spiritually. i just want people's thoughts about this

In the movie Clockstoppers, the main guy has a watch that speads up his molecules so that everything else appears to not move, although it is moving, just very slow by comparison. Since the human body would burn out by actually moving that fast, what would be the theory behind the bubble you'd need to create to seperate you from the normal flow of time?

i think the answer is that it does not reflect it but why is it so?though its molecules are loosely packed but are not absent.why are not we able to see it as somewhat light should be reflected.

Thanks, but I am NOT interested in the run of the mill regurgitated stuff. … ***I am looking for an elegant conceptual definition.*** … Like, for instance, the conceptual definition of gravity as the curvature of spacetime in the vicinity of a massive object, as set forth by General Relativity. Can you give an analogous conceptual definition of the field itself? Again, I am NOT interested in the traditional manifestations and definitions of the field such as lines of force, or its mathematical definition, or even more enigmatic exposé’s like: field is the region of space characterized by a physical property, such as gravitational or electromagnetic force or fluid pressure, having a determinable value at every point in the region, etc.

Evolution is about chaos turning up into order and design, while the laws of thermaldynamics say that all nature is going down from order and design into chaos. How can they both be true?

The theory is at this website...

The people have some quirks but I think the theory makes sense. The reason I'm asking about it is because I am not really that knowledged on the details of evidence for either theory and want to know your honest opinion on both the Big Bang theory and this WMS theory.

With the best technology nowadays,
can we demonstrate a zero-particle movement in a space fit for that purpose??
Can it be done either by a form of
A) a vacuum; can all the particles (not include those virtual particle stated in quantum theory) , like gas particles, proton, electron, etc. be pulled out a given space??
B) freezed particle; if the task all the gas particles , proton, electron, etc. to be pulled out is impossible, can we freeze the remaining particles in the near-vacuum space so that zero particle movement is maintained??

look forward to and thanks for any reply

A loaf of bread "knows" it is a loaf. After you cut it with a steel knife, you can't put the two halves back together and reform a whole loaf. How do the molecules on the edges "know" they are no longer a loaf?

Approximately: 282201568539770880000 cubic feet
282 Quintillion (rounded)
weighing
approximately 11288062741590835200 pounds! :-)
11.3 Quintillion (rounded)

I first determined the "approximate" weight of the atmosphere by calculating the average surface area of the earth: surface area = 4 x pi x r^2 = 4 x 3.1415 x (3900^2) = 191128860^2 miles
to square inches
191128860 x 4014489600 (square inches in a square mile) = 767284820729856000 sq/in of earth's surface
x 14.7 lbs (weight of atmosphere per square inch.) = 11279086864728883200 pounds
/ .04 pounds per cubic foot (to get the cubic feet of the atmosphere) *This is an averaged weight from sea level to vacuum of space = 281977171618222080000 cubic feet.

These numbers are slightly different than the ones above due to my use of pi.

We sometimes see movies with people valiantly hanging on during an explosive decompression in a spacecraft. Is that really possible? I want to know how fast the air is moving. It seems that it would be impossible to hang on, and that your lungs would immediately rupture. In any case, my real question is the initial airspeed. Is it 500 kph? 1000 kph? I know it will decrease very fast, depending on the size of the craft, and aperture size will count.

Newton sugested that everything in the universe could be clculated and measured but didn't know anything about quantum mechanics. without this element of phisics do you think he would be right. does this theory explain everything we cant measure or predict.
