Surely if it was purely random/chaos you would eventually see shapes and/or blocks of colour? So is there a reason why you don't see this?

Do you think that physics will ever be complete in the sense that there will no longer be any need for theoretical and experimental research in physics?

Let's suppose to be an astronaut travelling in the free space, without any gravitational force on you and without any near object to understand your current speed. Suddenly, a star appears at your backs and you start falling on it with a strong acceleration. Would you notice it?

-do protons decay?
-Why is there far more matter than antimatter in the universe?
-Why did the universe have such low entropy in the past, resulting in the distinction between past and future and the second law of thermodynamics? Why does time flow in one direction at all, on macroscopic scales, when there does not seem to be an arrow of time on the scale of fundamental interactions?

To measure the static friction coefficient between a 1.9 kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 470 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.053 m, what is the coefficient of static friction?

When the rubber band in a slingshot is stretched, it obeys Hooke's law. Suppose that the "spring constant" for the rubber band is k = 54 N/m. When the rubber band is pulled back with a force of 7.9 N, how far does it stretch? (answer in meters)

because according to the string theory, universes sometimes touch each other, Im jus wondering whether we see these "ghosts" at that precise moment when the universes touch?

Im not on DRUGS!! I just sometimes wonder about these things, am I weird or do any of you share or understand what Im saying here?

Let's say a ball is suspended in the air by a rope with a surface beneath the ball.

I then allow the ball to fall so that it is now half-way to the surface, and I continue doing this so that every time I let it fall, it is half-way closer to the surface than it was before. Common sense -- even the laws of physics -- tell you that eventually, that ball will have to touch the surface.

This is where I reach my dilema. If you keep allowing the ball to fall half-way to the surface, then it should be PHYSICALLY IMPOSSIBLE for that ball to touch the surface.

or...

Is there a point where there is no such thing as half? (The ball is so close to the surface that to drop it another half-way would be impossible because it has to touch eventually.)

Please, please help me!! I asked my physics teacher and he told me that he doesn't know and I'm dying to know!
