Default Einstein's Relative Time: Cancer of Human Mind

Neil deGrasse Tyson: "One of the towering great achievements of the human mind in our understanding of the universe is Einstein's theories of relativity. [...] It makes only two assumptions: that the speed of light in a vacuum is constant no matter who is doing the measurement and no matter in what direction you are moving or how fast. You always get the same measurement for the speed of light. That's Assumption 1 which by the way the experiment has shown to be true. [...] Given those two tenets, extraordinary spooky phenomena derive from them. For example: As you travel faster [...] time ticks more slowly for you than it does for other people who are not." https://www.youtube.com/watch?v=n2s1-RHuljo

That the traveling twin returns younger is an idiocy but there is something much more idiotic in the story: The youthfulness of the traveling twin does not follow from the two assumptions. That is, the assumptions, true or false, logically entail some conclusions, and "the traveling twin returns younger" is not one of them.

Tyson is lying when he says

"As you travel faster [...] time ticks MORE SLOWLY for you than it does for other people who are not."

Actually, special relativity says the opposite:

As you travel faster, time ticks FASTER for you than it does for other people who are not.

Here are Einsteinians who, unlike Neil deGrasse Tyson, are telling the truth:

David Morin, Introduction to Classical Mechanics With Problems and Solutions, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow..."

"The situation is that a man sets off in a rocket travelling at high speed away from Earth, whilst his twin brother stays on Earth. [...] ...the twin in the spaceship considers himself to be the stationary twin, and therefore as he looks back towards Earth he sees his brother ageing more slowly than himself."

So the correct prediction of special relativity is that, when he returns, the traveling twin will see his (stationary) brother younger than himself. The absurdity is obvious.

How can Einstein's relativity be saved? Some additional absurdity has to be introduced, able to neutralize the original absurdity. In 1918 Einstein admitted that special relativity is contradictory and turned to general relativity - he informed the gullible world that, during the turning-around acceleration of the traveling twin, a HOMOGENEOUS gravitational field appears which is responsible for a quick, almost instantaneous, ageing of the stationary twin:

Albert Einstein 1918: "A homogeneous gravitational field appears..." http://sciliterature.50webs.com/Dialog.htm

David Morin (quoted above) perhaps finds Einstein's HOMOGENEOUS gravitational field too idiotic but introduces it nevertheless - he calls it "enough strangeness" - words that may sound less idiotic to him:

David Morin: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow, but enough strangeness occurs during the turning-around period to make A end up older."
