Probablement des tas de conneries dans tout ça.
Certains physiciens racontent aujourd'hui la physique comme les moines du moyen-âge devaient raconter l'ascension du petit Jésus.
C'est dramatique.

Karl Gauss wrote, “I am coming more and more to the conviction that the necessity of our geometry cannot be demonstrated...geometry should be
ranked,
not with arithmetic, which is purely aprioristic, but with mechanics.”
I'm a bit uncomfortable with that, and so I'm uncomfortable with trying to reduce EVERYTHING to geometry. At least, Gauss put mechanics on an equal footing. I would say that his "mechanics" is dynamics. GR seems to subsume
dynamics into geometry.
Another thing about the video bothers me. The experience of the
traveler is
described in detail, but no mention is made of what happens to the distant observer, namely, all us guys. Consider the GPS. Time flows more
slowly for
us sitting on the earth relative to a point far away from us. Unlike SR where each twin sees the other's time slowed down, an observer in a gravity well sees the time of one who is far away flowing faster while the one far away sees us in the well flowing slower. This, in a sense, is an absolute difference, not relative like the SR case.
So a guy falling into a black hole sees time in the universe he's leaving going faster and faster until at the event horizon, all time in the
universe
has passed. So even if he could come back, there would be nothing to come back to.

I have no skills in mad mystical mumbling

But I have some skills in dealing with

It doesn't take much scientific knowledge to realize that physicists'
brains are not mentally healthy.

Saying that we are going to enter a black hole in the shape of spaghetti
and that we are going to come out of the other through a white fountain
into another universe, that's still being a little sick.
The solution to all this, or the unveiling of the problem, is almost religious. We must return to the ancient wisdom which we so lack today,
with wokism, crazy capitalism, Islamism, and all these antics which should have gone, in normal societies, into the dustbin of history.
"But you guys are seriously ill, if you weren't seriously ill, I would
have told you. But there you are, you are seriously ill, and you really
need a good doctor."
So yes, indeed physicists, like all other men (especially religious
people) are "a little sick".
But what follows is poignant and distressing, and it should make any
serious man cry. "But you say: we are not sick, we feel very well. In this you are wrong, and you make all useful preaching vain."
Now, having said that, you shouldn't throw the baby out with the
bathwater.
We should not reject everything in science, obviously.
When you look at the Concorde or the Tupolev, when you look at
a 4K screen,
when you study the accelerated particles,
you say to yourself: “They still worked well”. There are obviously quite a few
truths in their science.
Unfortunately, Dr. Hachel has no scientific knowledge.
For example, he proposed E = mc^2/(1 + v^2/c^2)

I would like to discuss with you, but I would like frank discussions, discussions where we lie.
Even Python, who doesn't like me at all (to say the least, lies less than you).

Sorry, I inadvertantly left off the square root factor. But
the good doctor is forgetting that he claimed gamma should be
1/sqrt(1 + v^2/c^2), n'est-ce pas?
