Has time dilation or twin paradox been proven by astronauts traveling in space at high speeds?

If so please provide the website.

    NO, it has not been "proven." Time does appear to be distorted but the clocks are effected by many different things. Different gravity and speeds can effect the oscillation, therefore it can not accurately be measured under such conditions, even in atomic clocks. Although the methods they use vary, all oscillating clocks, mechanical and digital and atomic, work similarly and can be divided into analogous parts.

    Source(s): Time is a man-made reference used for convenience and as such the idea of a "curved space-time" is delusional, hence there is no basis for the Relativistic "space-time" binomium concept. I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view.-Nikola Tesla

    Yes by using atomic clocks in airplanes and space.

    There are other ways, however, to put his ideas to the test. How do we know Einstein had it right? One experiment in the 1970s provided some pretty strong evidence:

    Atomic clocks are extremely accurate clocks that can measure tiny amounts of time—billionths of a second. In 1971, scientists used these clocks to test Einstein's ideas. One atomic clock was set up on the ground, while another was sent around the world on a jet traveling at 600 mph. At the start, both clocks showed exactly the same time.

    What happened when the clock flown around the world returned to the spot where the other clock was? As Einstein had predicted in a general way, the clocks no longer showed the same time—the clock on the jet was behind by a few billionths of a second. Why such a small difference? Well, 600 mph is fast but still just the tiniest fraction of the speed of light. To see any significant differences in time, you'd have to be traveling many millions of miles an hour faster.

    Yes, time dilation has been proven to actually exist. Two highly-accurate atomic clocks were precisely synchronized. One remained on the ground, stationary relative to the other one which was flown around in a high-speed jet for a period of time. When the two clocks were brought back together again there was a measurable difference in time between them.

    Yes, it has. And every time (no pun intended ☺) someone comes up with a new and slicker way to measure smaller time intervals, one of the very first things they do is to measure the speed of light and the amount of time dilation caused by relative motion between reference frames.

    Everyone who said YES is WRONG. No, it has not been proven because clocks are flawed. if you put a clock on earth and one on a planet with a different gravity they would tell time differently because of the way a clock works.

    As it happens, yes, it has. Way back in the mid 1970's, special aircraft did some tests and prooved the theory. One does not need to go into space.

    Yes but the time diffrence is still really small but it is there.
