I understand about lowering the freezing point of H2O. But if cold is the absence of heat then adding salt doesn't remove any energy/heat. Why doesn't it simply melt into liquid and stay the same temperature?

For example, if I turn on a flashlight, does the light push back against the flashlight? And how much light would have to be released in order for me to feel the push of the photons?

and sound obviously has a delay to a person stood a certain distance from where the sound is made, is that the same for light? so if you can see something far away, its not actually where you see it due to the delay of light getting to you? thats better than any ''how many dogs have you got?!'' question.... just lol

Do you think it's at all possible for our race to out live the universe? If so, what sort of odds would you give us?

Assuming that an intelligent race suvives long enough on this planet, how long do you think it will take before we have come to understand all that is and reached the end of scientific discovery?

Why ? I can lift an object, say a small stone, straight up at say 3cm/sec with very little effort. Hypothetically, if I kept on applying the same amount of effort the stone would continue to rise until it eventually left the Earth's atmosphere, right ? So the stone left the Earth but travelling at only 3cm/sec. If this is correct, surely the same principle could be applied to a much larger object, say a space shuttle or space station ? Obviously the amount of effort required would be greater, but the shuttle could still leave the Earth at a much lower speed.

If a cat always lands on its feet and buttered toast always lands butter side down. Could I get a cat and attatch one piece of buttered toast butter side up to each paw of the cat then picked the cat up and dropped it would the butter side up toast and the cat paws kinda act like like poles of a magnet and repel each other leaving the cat to kinda levitate a few inches above the floor or possibly rotate constantly along its latitudinal axis thus creating an anti gravity machine?

The Q above is the headline Q for the following expanded Q I really wanted to ask but couldn't, because of Q-box constraints:

"When will the day come when scientists studying the nature of matter and energy, admit to themselves, and to eveyone else, that there are somethings that are believed or reasoned to exist but are scientifically unknowable because they, whatever things they are, are undetectable and unmeasurable by the physical methods and procedures of science?

Can you use sound waves to create friction at a distance and have the friction create power at the new location.

like think about it, its a load of gas right next to a complete vaccum, why doesnt the whole earth depressurise? i dont buy gravity holding it there because the pressure differential between atmosphere and vaccum is huge. (hence space shuttles getting in a bit of a mess if a hole suddenly appears in the hull)
