this sounds like a very stupid question (much like the first one I did; after reading that article, I occassionally had deep thoughts). Has science proved something that will exist forever; even if the universe or everything else gets destroyed? Even when time itself ends?

Is time really infinite? If so, what does the "end of time" mean?

Say you are looking at a stage and see the scene clearly. Next imagine a curtain made of photons falls down. Would you still be able to see the scene clearly? Or would the light from the stage have interference from the light falling down? Imagine you are in space so that reflection off of air molecules is eliminated.

the direction the vehicle is moving?

I have noticed that when you bounce a ball inside a vehicle it tends to travel with it. meaning it comes up in the same spot.

What is the reason behind it?
