Would humans age faster on Jupiter?
821704
Due to gravitational time dialation.... humans would actually age slower on Jupiter then say... on earth.  This is because the more gravity there is, the slower time moves because gravity is the warping of space-time.  Now if you somewhow lived on jupiter (not possible really because of the lack of surface, high gravity, and pressure), it would seem people on earth would age faster.  I'm not sure on the differences but it would probably only be in seconds over a lifetime.

Not even close.  If Jupiter were about 13 times bigger, it MAY (stress - MAY) have experienced deuterium fusion for a few thousand years, then died.  Significantly larger - 65 times or so, would fuse deuterium and lithium, but again, only for a very short time.  However, Brown dwarfs have convective surfaces and interiors, meaning the layers are constantly churning and mixing due to heat.  Under about 13 times Jupiter's size, the body is separated into layers and considered a planet.\n\nThe tiniest stars capable of full fusion are, at a minimum, about 100 times larger than Jupiter.  \n\nHowever, and this is the weird part, we're talking about mass, and the main differentiator is how that mass reacts and what forces are in play.  Which means Jupiter, the Brown Dwarfs, and the tiniest smallest stars are all about the same physical size, just massively different densities.

I saw a lot of good answers out there that hit the answer pretty much on the head.  I only wanted to point out one minor mistake in what you wrote (which you probably won't run into in most freshman courses in relativity).  That the astronauts would actually be older than those who stayed on Earth.  The special relativity people were explaining was correct.  If you move => time slows down.  The thing is that gravity has a greater effect in slowing down clocks and the gravitational field you experience in orbit is weaker than on the surface of the Earth (obviously it won't matter though if you are flying around space at speeds near the speed of light, then the special relativity part becomes dominant over the general relativity i.e. gravity).

Nope that would be dead wrong. pun intended. There is no doubt you will die long before an ice-age. The next ice-age will be in a couple million years and your life expectancy on average is 67 years so you will be dust by then.

Jupiter is further from the sun, and has a larger orbital path.  That is why it takes longer (it has to travel further to go around)

Jupiter takes 11.86 years to orbit the Sun, also known as its "orbital period".  \n\nThis is entirely determined by the fact that it is, on average, 5.2 times further from the Sun than the Earth is.  If you wanted to derive the orbital period yourself, one uses Kepler Third Law.  Just take the number 5.2 and raise it to the (3/2) power, and you get 11.86 years.\n\nOne of the weird things about Jupiter is its rotation.   One "day" on Jupiter is 9 hours 50 minutes if you're at the equator, but 9 hours 55 minutes at the poles.  This is because the equator actually spins faster than the poles...a planet can do that when it's not a solid.

An ion engine will get you there the fastest. You get the biggest delta-vee per kg of exhaust. \n\nProblem is, in general you only get one encounter with a specific planet once each solar orbit, and you can only get a kick so large each time. I suppose you can hypothesize a super convenient planetary alignment that could shave off some time, but you might spend a long time waiting for that particular configuration.  A lot of really smart people spent a lot of time developing the computational tools to come up with the VEEGA and VVEJGA options.  I doubt the population here is going to come up with anything a lot better.\n\nYou can read more about the DS1 ion propulsion experimental system here:\nhttp://nmp.nasa.gov/ds1/tech/ionpropfaq.html\n\nThe first science mission using ion propulsion is the Pluto bound New Horizons.  Thanks to this tech, it will reach pluto in 10 short years and reaches Jupiter for a gravity assist in only 1 year.\n\nhttp://pluto.jhuapl.edu/mission/mission_timeline.html

Jason, that's bullshit.\n\nOur planet doesn't have to rotate at any particular pace to stay in this orbit.\n\nObviously though, if it rotated 20x slower, the days would be 20x longer and the nights would be 20x longer as well.  This would mean that part of the Earth would heat up much more while the other side cooled much more.  As long as we still had an atmosphere like the one we have now, this would probably cause a lot of storms and wind also due to the extreme tempurature differences.

Einstein was referring to Time Dilation.  Time dilation would make it possible for a fast moving clock to travel into the future, while aging very little. That is, the clock (and according to relativity, any human travelling with it) shows less elapsed time than stationary clocks. For sufficiently high speed the effect could be dramatic. For example one year of travel might correspond to ten years at home. Indeed, a constant 1g acceleration would permit humans to circumnavigate the known universe (with a radius of some 15 billion light years) in one human lifetime. The space-travellers could return to earth billions of years in the future (provided the Universe hadn't collapsed and our solar system was still around, of course). A scenario based on this idea was presented in the novel Planet of the Apes by Pierre Boulle.\n\nA more likely use of this effect would be to enable humans to travel to nearby stars without spending their entire lives aboard the ship. However, any such use of this effect would require an entirely new method of propulsion. A further problem with relativistic travel is that the interstellar medium would turn into a stream of cosmic rays that would destroy the ship unless stark radiation protection measures were taken.\n\nCurrent space flight technology has fundamental theoretical limits based on the practical problem that an increasing amount of energy is required for propulsion as a craft approaches the speed of light. The likelihood of collision with small space debris and other particulate material is another practical limitation. As a result, time dilation is not currently a major factor in space travel.\n\nIf you would like further explanation of this theory, just let me know.

We cannot leave our solar system until we figure out how to travel at much higher speeds than we can now.  Even if we could travel at 1/2 of light speed, it would still take 8 years to get to the nearest star.  The crew would have very little to do during the voyage.  And, they'd have to carry supplies for the 16-year round trip.  The ship would be enormous -- certainly larger than anything we have ever built.\n\nUntil we can find a way to travel at speeds faster than light, we will not be able to visit other star systems.

If you are getting older  could be due to aging process

No. Even if the human race moves-on to distant planets, the universe will remain diverse and we will not look the same.  \nJust watch an episode of "Red Dwarf."

If earth's gravity is 1, Jupiter's gravitational pull is 2.64 times that of earth, So the fall would be much faster. The gravitational pull on Jupiter is over 2 and a half times stronger than Earth's. Imagine a roller coaster falling twice as fast!\n  \nThe gravitational pull of Mercury is .38 times that of earth. \nOn Mercury the gravity is so small that the fall would have to be about three times as long to get the same speed as on Earth.

Afraid not.  The only planet in our solar system that has the temperature and atmosphere that will sustain life is good old Earth.

not millions of years, as the previous answers say.  try about five billion years from now.  at that time, the sun will have used up its supply of hydrogen fuel.  it will try to burn off the helium that now fills its core, and expend so much energy in the process that its outer layers will expand beyond the orbits of mercury and venus, and making earth's surface semi-molten (if it doesn't destroy the planet).  it will thus become a red giant.  as it slowly cools and fades, it will shrink to become a white dwarf, and finally die out as a black dwarf.  hopefully before then, we'll have long since been gone, if we haven't destroyed each other by then.

I worry more about mass extinction events like an asteroid impact or finding out that giant aliens have just been raising humanity as a food source to harvest en masse. Bird flu might do a job on us or some alien organism brought back by space exploration which our bodies are unable to manufacture antibodies. Maybe global nuclear conflict will leave the earth a smoking glow-in-the-dark beacon rotating and wobbling in the solar system. Excuse me I have to go find my aluminum foil hat to block the gamma rays. Wait what if planet Jupiter is a brown dwarf star and decides to go nova? What if the sun flames out? What if the magma in the earth's crust makes the poles flip positions? .........
