A Mercury barometer is a 1 meter long glass tube with the top sealed and turned upside down in a bath of mercury the pressure on the surface of the bath of mercury lifts the level of the mercury in the tube dependent on atmospheric pressure.

Would we age faster if we could live closer to the sun since time is related to mass gravity since the larger the mass the more gravity it would have?

Actually, that's a good question. Me being no scientist, but I'll give you my advice. Under one of Einstein's theories, the faster you go, the less you age. And the innermost planet (Mersury) atually orbits faster then Earth does so we age less, but that difference is miniscle. And talking about gravity, let's say perhaps a blackhole. A blackhole slows time so much, that if a object was past the event horizon, it will not seem to move, effectelvly meaning if you looking at a object go into a black hole, time would stop, leaving the object there as long as you keep looking at it. So I would expect more gravity to slow down your age, instead of increasing it. But since we are talking about living closer to the sun, it wouldn't atcually matter, because the difference, if there is any difference would be so small, you would probally gain or lose only a few milliseconds or seconds in your life. So my final answer is I would expect you to age less, if we were living closer to the sun. This might not be true, but from what I've read, this is my final answer. P.S Don't take my answer seriously. I'm no scientist, so what I'm porposing is entirely a theory. : Main article: Time dilation "Time is nature's way of keeping everything from happening at once". This quote, attributed variously to Einstein, John Archibald Wheeler, and Woody Allen, says that time is what separates cause and effect. Einstein showed that people traveling at different speeds, whilst agreeing on cause and effect, will measure different time separations between events and can even observe different chronological orderings between non-causally related events. Though these effects are minute unless one is traveling at a speed close to that of light, the effect becomes pronounced for objects moving at speeds approaching the speed of light. Many subatomic particles exist for only a fixed fraction of a second in a lab relatively at rest, but some that travel close to the speed of light can be measured to travel further and survive much longer than expected (a muon is one example). According to the special theory of relativity, in the high-speed particle's frame of reference, it exists, on the average, for a standard amount of time known as its mean lifetime, and the distance it travels in that time is zero, because its velocity is zero. Relative to a frame of reference at rest, time seems to "slow down" for the particle. Relative to the high-speed particle, distances seems to shorten. Even in Newtonian terms time may be considered the fourth dimension of motion; but Einstein showed how both temporal and spatial dimensions can be altered (or "warped") by high-speed motion. Einstein (The Meaning of Relativity): "Two events taking place at the points A and B of a system K are simultaneous if they appear at the same instant when observed from the middle point, M, of the interval AB. Time is then defined as the ensemble of the indications of similar clocks, at rest relatively to K, which register the same simultaneously." Einstein wrote in his book, Relativity, that simultaneity is also relative, i.e., two events that appear simultaneous to an observer in a particular inertial reference frame need not be judged as simultaneous by a second observer in a different inertial frame of reference. ------------------------------------------------------------------------------------------------------------ You should use this for reference. I got it from http://en.wikipedia.org/wiki/Time#Spacetime Wikipedia is really useful. And I can't seem to find anything about gravity to do with time on the net, but I know I've seen it somewhere...Hope I helped you!!!
