Dr. Lincoln Is Wrong About The Twin Paradox (Special Relativity)

- A famous resolution of the twin paradox on RUclips has been done by Doctor Lincoln and even though it might seem legit, it is in fact wrong.
Doctor Lincoln claims he solved the paradox without acceleration by introducing not two but three observers but the Lorentz transformations were incorrectly used and the problem presented in his video is in fact just hidden clock synchronization problem.

It's hard to find a video of Lincoln where he doesn't make at least one inaccuracy. He carries around a set of misconceptions in his head that he then uses to confuse his students and send them on their way lol
The absolute best explanation can found on the FloatHeadPhysics channel.
Space and Time are separate frames of reference. Clocks are instruments that measure motion in space. The energy from the sun accelerates plants through the lifespan. Going faster in space doesnt necessarily change the amount of energy in the system. Not when you can just add more.
The only issue I have is that your animated rocket engines have a flame out the back.
Nicely calculated. Don Lincoln doesn't understand relativity beyond what you'd learn in high school. To be fair his understanding of particle interactions is excellent.
Yeah that dude is a science ‘communicator’ who undoubtedly has others do his physics for him, he tries to confidently explain deep ideas on a surface level for the interested layman, so I expect mistakes in both theory and interpretation.
Exact! IMHO with accelerations out of the equation you have indeed exact symmetry between the two twins and you are facing the paradox.
If you are in strong gravity you age less as time flows slower. Gravity and acceleration are equivalent according to Einstein. So it is obvious that acceleration is what makes the traveler age less.
What always bothered me in the original twin paradox, where one stayed home and one went across the galaxy, was that the one traveling at relativistic velocity would be younger after the trip. But my question is why? There is no reference frame that is standard. No difference between the first one or the second one moving. They BOTH move RELATIVE to each other. At 1/2 c, or less. There is no ground to stand on.
Firstly, light and observers have nothing to do with time. Turn out the lights and you may start to get a sense of what time is. Any experiments involving light and observers will be inconclusive. Everything happens in the present. Time dilation is merely the change in the rate at which objects age due to gravity warping space. Those objects are still in the present its just the rate at which they age is different.
Very good script and graphics. You demonstrate through you presentation and demeanor your intellectual authority.
Great explanation!
I questioned Dr. Lincoln's explanation. When it comes down to the twin's paradox, it boils down to the question why, if each twin was travelling at the same speed relative to the other, will one have aged faster than the other when they meet up again on the return. It can only be due to a difference in their experiences, and the only thing that breaks that symmetry is that one of them was changing their inertial frame of reference, and that only happens if they undergo acceleration.

I agree with you 100% - I saw that Fermilab video years ago and absolutely rolled my eyes. For someone to declare themselves an expert and get in front of people on RUclips like that, and get it WRONG, is just pathetic.
What a mess, but I thought the same about Doc Lincoln's explanation.
In any case, the solution to this "paradox" is to calculate the proper times of the two world lines. Without a clear definition of proper time, a confusion arises.
Another possible angle to look at the problem is invariance of space-time intervals.
Instead of just saying acceleration is resonsible for age difference, I would say the uniform motion parts are also responsible.
Absolutely brilliant. Side note: at
