Don't think I'm odd for asking this, but it has been bothering me. I just can't stand reading Stephen Hawking myself. Please tell me what you know, or your independant theory.

protons, neutrons, and electrons. working together like perfect clockwork. an input then a processor and then an output with some form of memory to hold the information is basicaly all a computer is so... the proton being the input the neutron being the processor and the electron would be the output. The memory would be stored in electromagnetic fields. Is any of this making any sense?

I'm given an equation: v= c1 e^(-C2t)

Supposedly, I'm to find the units for variables C1 and C2.
Now, I'm wondering if the e^ will do anything to the units...

If not, I have my units as: C1 = m/s and C2 = 1 / s = Hz.

I'm using the formula F= G*((m1*m2)/r^2)
Since i no the force of gravity is 9.8 m/s on earth, i input earth's mass(5.9742*10^24 kg), my mass(50 kg), and the distance between the earth and me(6.372*10^6 m). The gravitional constant is 6.6742*10^-11 m^3 s^-2 kg^-1, i run the numbers and i end up with 491.0180353 kg m s^-2, not even close the 9.8 m/s, what am i doing wrong?

Spring scale A is attached to the floor and a rope runs vertically upward, loops over the pullley, and runs down on the other side to a 120-N weight. Scale B hangs a 120-N weight. What are the readings of the two scales A and B? The weights of the scales are negligible.

Any help is appreciated...Thanks

The coefficient of static friction between a block and a horizontal floor is 0.40, while the coefficient of kinetic friction is 0.15. The mass of the block is 5.0 kg. A horizontal force is applied to the block and slowly increased. (a) What is the value of the applied horizontal force at the instant that the block starts to slide? (b) What is the net force on the block after it starts to slide?

The planet in question is nanoseconds from being sucked into a black hole. Now, as impossible as it would be, lets assume that there is still an atmosphere on the planet and its gravitational force "somehow" has enough sway over the black hole to pull the tree to the ground. The tree crashes nanoseconds before the planet inters the hole, but our listening device is just far enough out of reach for the sound to travel to it in those few nanoseconds.

So... Does it make a sound?

THERE ARE research jobs on z.p.e, and a govt lab, SANDIA NTL LAB? has a Z-generator. How dangerous is this research? could there be any danger of discovering a ""new particle"", a new ""process"" that we could not handle? or maybe this energy could open a gap in the space time continuum? (correct me if I am wrong)
