Why is NASA still spending billions of dollars on the space station?

If Nasa has some of the smartest people working for them on the planet, (No offence) then why are they still spending billions of dollars keeping people in space when it is a fact of science that there is no infinet sources of energy avaliable to travel more than a million miles or so away. Whats going on up there??

Science Says That There Are Hundreds Of Different Light Spectrums And We Can Only See A Few?

What are we missing?Is there somethings in these other spectrums that we can see such as dimensions where the ghost figures that people seem to see from time to time when there is a split moment or maybe the light hits the other specturms just so ,and we are able to see within those spectrums? If there are so many things we cannot see what else are we missing?

Force exerted by a table on a falling chain?

A chain of length L and mass M is held up above a table. The lowest part of the chain slightly touches the top of the table. When we let go of the chain, it starts falling on the table and we assume that each link comnes to rest the instant it reaches the table.
Find the force exerted by the table on the chain after this has fallen through a distance x.

The distance fallen = x so the rest of the chain that is still in 'upright' position is L-x.
At first when we hold the chain up, the force F=mg is 0 since no mass is touching the table. I understand that the force depends on the length that lies on the table at that moment but how do I calculate this?? Can it be something like Mgx/2L ?
