Solving the Twin Paradox - A Rigorous Approach

In this video, I rigorously unravel the famous Twin Paradox using the principles of Special Relativity. Contrary to common misconceptions, Special Relativity is perfectly capable of dealing with accelerated frames of reference, General Relativity is not needed. Discover the truth behind time dilation and the journey of our cosmic twins, all backed by clear, accessible explanations and calculations. Don't miss out on understanding one of physics' most intriguing puzzles!

This is really well explained! Thank you! 💗

Just a small point. You do need GR to define what an inertial reference frame is. Inertial frames are the free falling frames. Technically it is not necessary because you can mathematically define it. But the conceptual step of finally understanding what an inertial frame is would not have been possible without arriving at GR first. I thought I would make the distinction between strictly necessary and conceptually necessary without the benefit of hindsight.

Let's work with the postulates of Einstein's theory of relativity.❤❤
And if we apply new technologies for this, using the experience of Michelson Morley on the airplane fixing speed 200, 300, 400 m/s., we will see how quantum gravity works. Such measurements are impossible on the satellite due to weightlessness.

19:30 traveller travelling at 0.95 speed of light can't change direction ! its reasonable to bend the space to manuover like it taking U turn from Blackhole. Thus we do not have to consider manuover. Another Approach is to do retardation after agreed acceleration reached --> stop--> change and start acceleration in negative direction --> start retardation once same acceleration reached in negative direction. This profile adds four sequence of operations, however that would be more practical. Moreover, 95% speed of light is not possible with rocket load - [imagine what weight it would have to carry to launch ] . however, if you can only perform 0.01% C of some reasonable value of acceleration and show its trivial effect, that would also back up your theory and bring your calculation within the periphery of experimental limits. Your efforts are admirable.
