and how did they prove the sun is powered by conversion of hydrogen to helium? did they send a probe into the sun? where does all the "hydrogen" come from?
what sort of experiment did they perform to come up with the hypothesis (and thats all it is) known as a black hole?
lastly i did not comprehend your last word and sentence. ie; "somewhat falsifiable". did you mean feasible?

Hi there! Glad to see you.
Are you referring to entropy - the augmentation of randomness, and loss of heat in say a bucket of hot water?
They have a clock on board that shows they were not flying for 50 years. So how can you say "they were flying for fifty full years"? Their clock says they weren't.

It wouldn't be time slowing down that kept them young, because as far as time is concerned they were flying for fifty full years; it's that their atoms stopped aging at the speed of light.

I, as the oppostion, say, "quarks don't exist". Prove me wrong.
I also say, "redshift from other galaxies is not caused by general rush-away-from-each-other movement, as many galaxies actually move towards one another and even collide. Instead, redshift is caused by photon interaction with space itself". Prove me wrong.
I also say, "Einstein's Relativity is inaccurate - time will not slow down for a fast-moving body, as any thought experiment involving a third party, always at equal distance from both the "immobile" and the fast-moving body, would show. " Prove me wrong.
I finally say, "if virtual particles exists even in total vacuum, how come the CERN is never picking them up? " Prove to me quantum model is the right one.

You didn't debate, and you certainly didn't prove me wrong. Do you know anything about physics at all, or are you just trolling around?
It's certainly possible to make a clock that's affected by acceleration forces. You can imagine a grandfather clock where the pendulum gets pegged to one side in acceleration and stops...so you have to design a clock that doesn't have this kind of vulnerability.

The Hafele–Keating experiment used atomic clocks, and has undergone a lot of scrutiny, and has been verified by subsequent experiments, so the criticisms of this experiment have been shown to be in error:
the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.
If however someone can find a verifiable flaw in the experiment and subsequent experiments due to the clock mechanisms, then they would still have the problems of other time dilation effects seen in radioactive decay rates to address.
Because the Hafele-Keating experiment was reproduced by increasingly accurate methods, there has been a consensus among physicists since at least the 1970s that the relativistic predictions of gravitational and kinematic effects on time have been conclusively verified. Criticisms of the experiment did not address the subsequent verification of the result by more accurate methods, and have been shown to be in error.
The point being? You have two different clocks showing that two different amount of times have passed. Relativity says both clocks are right. Assume both clocks have the same power source which is adequate for at least 60 years of accurate time measurement...I'm not sure what you're getting at there. If power loss were an issue it would be a problem with the faster running clock, since the power source is more likely to become drained after 50 years than after a few years...so that argument doesn't even make any sense because it would make the Earth clock run slower, not the one on the space ship.

I'm not sure what you think that would show that hasn't been seen in other experiments, but no, I'm not aware of a clock on the moon, and back in 1969-1972 the accuracy of clocks was nowhere what it is today, when we can do experiments like this without going to the moon:

I'd be curious to see one of those clocks placed on the Moon and observe the effects that result. Do you know if anything like that has happened?
When we can measure the effects of gravity and velocity this precisely, putting a clock on the moon doesn't seem to offer any benefit, though I have no objection to it if you can find the funding to put one there.
in the Hafele–Keating experiment the atomic clocks differed after their journeys by just tens to hundreds of nanoseconds.
Thanks to improved timekeeping, similar demonstrations can now take place at more mundane scales in the laboratory. In a series of experiments described in the September 24 issue of Science, researchers at the National Institute of Standards and Technology (NIST) in Boulder, Colo., registered differences in the passage of time between two high-precision optical atomic clocks when one was elevated by just a third of a meter or when one was set in motion at speeds of less than 10 meters per second.
FARNBOROUGH, England — A possible rover mission to Mars within the next eight years may rely on a larger parachutes, atomic clocks and inflatable decelerators, NASA's Mars exploration chief says.

That's the whole idea behind relativity. Time is not constant, it's relative. Maybe you're getting it? Then again maybe not, I'm not sure.

I don't see these clocks operating on a universal constant. Even on Earth you've shown that they are sensitive to changes in elevation and motion.
How can you tell the difference between timekeeping with a cesium atomic clock, and time?
I think it would show that the clock would show that the difference is in timekeeping, not time.
