I think that light is mass, because black hole can suck it. Also, gravity can bend it. I am not a scientist but a mathematician. I need help.

You have two coloress molecular liquids, one boiling at -84C and other at 34 C both at atmospheric pressure.

Which of the following statement is correct? Correct those that are not.

1). The higher-boiling liquid has greater intermolecular forces than the other.

2) the lower boiling liquid must consist of nonpolar molecules.

3) the lower boiling liquid has lower molecular weight than the higher boiling liquid

4) the two liquids have identical vapor pressure at their normal boiling points

Due to the natural speed limit that this universe provides us with, interstellar travel will never be possible for an individual person - if we were ever to actually try and reach for the stars, we would have to build a civillisation in space. I know that in space they test the effects of zero grav on almost everything.. have they tried concieving a child? if so, how about the pregnancy? does anyone here think that human rights groups would tolerate the necessary experiments if it meant possible complications to a pregnancy?

guess that's kind of a lot of questions.. thanks in advance

If I take a ball made of a solid structure and remove the air, is it possible to make it float? The ball would be rigid, not like a balloon, so that it can withstand the vacuum inside without collapsing.

Air pressure is 15 pounds per square inch - if you reduced this to half that value inside the ball, would that mean it has an upwards force of 7 pounds per square inch, so it would float off the earths surface and into the atmosphere?

Have you ever looked up at night and thought about how all those stars were created? And did you think that our sun is going to stay the same for the rest of eternity, wrong, the sun will run out of gas and not be strong enough to heat earth in billions of years. Bet you didn’t know that.
