It's possible in principle but it's never going to actually happen because of the technical challenges to overcome, not to mention the extraordinary cost.kannank@live said:This is an extension of twin paradox of STR. Suppose when the father was 30yrs old, he got into this flight which moves close to c. After a while in that he comes back to see his Son older to him! I'm sure this is a possibility from time dilation. Is this really possible? If so, how is the father going to explain all this to someone else who doesn't know about his space trip! :-)

But explaining how something happened without letting them know what happened is impossible, don't you think?
That may be true but you have just changed the scenario that the OP described so it isn't relevant. The OP said, "he comes back to see his Son older to him".backward said:There is hardly anything surprising about it. If the father travels long enough with a velocity close to the speed of loght, he may come back only to find that millions of years have passed on the Earth and the explaining can't be done because there is no one left to explain to!
Really? This is your concern? How to explain physical results without disclosing the relevant physical facts?kannank@live said:If so, how is the father going to explain all this to someone else who doesn't know about his space trip! :-)
The Father-Son Paradox is a thought experiment that illustrates the concept of time dilation, where time moves at different rates for two observers in relative motion.
The concept of the Father-Son Paradox was first proposed by physicist Albert Einstein in his theory of relativity.
The paradox involves a father and son traveling in a spaceship at high speeds. The father ages more slowly due to time dilation, while the son ages normally on Earth. This is because time moves slower for objects in motion compared to those at rest.
While the paradox is a fictional scenario, time dilation is a real phenomenon that has been observed and proven through experiments with high-speed particles and atomic clocks.
The Father-Son Paradox highlights the fact that time is not a constant and is relative to an observer's frame of reference. This has important implications for space travel, as astronauts traveling at high speeds will experience time differently than those on Earth. This must be taken into account for accurate navigation and communication in space.
