On their 20th birthday, identical twin astronauts volunteer for an experiment. Terra will remain on Earth, while Stella will board a spaceship. Stellas ship will travel to visit a star that is 10 light-years away, then return to Earth. As they prepare to part ways, the twins wonder what will happen when theyre reunited. Who will be older? Amber Stuver investigates the Twin Paradox. Lesson by Amber Stuver, directed by Aim Creative Studios

This method of explaining the paradox, makes no sense to me at all. But here is the funny part. Despite me not having any physics education at all, I managed to discover the Special Relativity(SR) phenomena by myself, and I derived the SR mathematical equations by myself as well. That was a gazillion times easier to do than making sense of this one sided paradox explanation. To discover SR by yourself, all you have to do is perform a simple step by step analysis of Motion. Even a high school dropout can do it. But sadly, people have been taught over and over and over and over again, NOT to see that many things are far simpler than they appear to be.

Narator: First of all the faster an object moves through space, the slower it moves through time, compare to an unmoving observer. UNMOVING OBSERVER. When the earth rotates, so the observer must be move in some way. So if the fast object cant be observe from an unmoving spot, then the twin paradox experiment had not conduct corectly? BTW, in our vast universe, is there any spot that not moving at all?

Special relativity really makes you think about philosophy. Philosophers have argued if our perceptions are a reflection of a true reality or are a reality unto themselves. Special relativity offers empirical evidence that our observations are reality, and changing the way in which we observe alters time and space itself.

im sorry but this is the problem with physicist, what you explained here was only how the frame of reference should be taken, not the paradox itself, that would involve explaining why time moves slower, you just presented an equation and assumed everyone knows it.

I was trying to understand because to be completely honest i didnt but once you said that when shes coming back thats when should would begin to notice her sister aging faster it made sense
reply

Can someone explain to me the anatomy in this problem? Like how did the twin in space didnt age physically if the body itself doesnt has to do anything with were we are?

reply

even if you are in a space ship why would she age difrently then someone on the planest earth? should you be aging the same no matter where you are?
reply

She wouldn't be an astronaut if she was overweight and unhealthy as shown by this body positive animation. Come back to Earth, please.

What if our universe was non euclidean and Stella would not have to change her direction to return back to the starting point?
