If we had an ideal copper wire, with no deformations of any kind on the whole length of the wire, and we apply two horizontal forces on the both ends of the wire and therefore, stretch it. First, it would expand, and then, it would break. But where? In the middle? On one of the ends? Where?

If I swing some object attached to a rope around myself in the horizontal plane and I wish to bring it closer, I have to pull the rope. The law of conservation of angular momentum states that the velocety of an object will increase, also, the kinetic energy of the object will increase, so, some work must be done on the object. But how can work be done on an object when the tension of the rope (the centripetal force) is always perpendicular to the object's velocity and therefore cannot perform work. What force accelerates the object?

Suppose a person takes a trip in a rocket ship from one planet to another at a speed that is significant to the speed of light say at least 10%. at a point exactly half way between the two planets his path is exactly perpendicular to the line of sight of another observer on a third planet at least as far away as is the person in the rocket ship's trip. At this point the person on the rocket ship fires a beam of light or a radio transmission at each of the planets he is traveling between. According to theory the speed of light is the same for all observers. So the person in the rocket ship should see each beam traveling away from him at the same speed thus the beam of light reaching each planet at a different time. But the observer on the third planet should also see each beam travelling from their point of origin at the same speed and reach each planet at the same time. How is this possible?

Gravity technology, if you beleive those who claim it, has been around and can supply us with propulsionless travel. Why has the technology not been revealed. I just want to know. Is it due to aliens, the danger inherent in such devices or something else, etc?

Ok, I know that the electron charge is the same but opposite to the proton charge. But why? A proton is much larger, and much more massive than an electron. Why the charge is exactly the same? Why not one is a fraction of the other? Why is not a multiple? Why exactly the same?

If you are in a car or a boat and drop a ball in your hand, how fast is the ball going in the horizontal (x) and vertical (y) direction? If you think hard enough and connect it to light, you’ll start rolling down Einstein’s road of relativity.

Strange as it may seem, if a rifle is fired horizontally and a bullet is dropped at the same time, they hit the ground at the same time. This is because all things fall at the same rate, no matter how fast it may go horizontally. See if you can verify this phenomenon or diprove it.
Why?

Actually, the article was about speeding up decay time. If you supercool a radioactive element, apparently the decay time falls exponentially. The german guy said it also worked for the reverse process, fusion (the particles would fuse easier when supercooled). Does this have any implications for fusion research, bla bla bla?

Decay products are classified as either alpha, beta or gamma. State which type(s) of decay particle applies to

Same mass as an electron

If I am standing in an elevator (lift) that is moving up and I press down on the floor of the lift with my legs, will the force that I am exerting with my feet make the elevator do more work to go up?

Is this similar to some more weight being placed in the elevator which would make the elevator do more to go up?
