Can Physics Be Too Speculative?
/ Posted by Sabine Hossenfelder /
------------
Imagination . . .
Multiverses, dark matter, string theory, fifth forces, . . .
Have physicists gone too far in their speculations?
. . . where to draw the line between science and pseudoscience.
. . . . Dark matter is an example of a research program that used to be progressive but has become degenerative.
. . . guessing a specific particle from rather unspecific observations of its gravitational pull has an infinitesimal chance of working.

Theories for the early universe or fifth forces suffer from a similar problem. They do not explain any existing observations.
Instead, they make the existing – very well working – theories more complicated without solving any problem.

Multiverse research concerns itself with postulating the existence of entities that are unobservable in principle.
This isn’t scientific and should have no place in physics. The origin of the problem seems to be that
many physicists are Platonists – they believe that their math is real, rather than just a description of reality.
But Platonism is a philosophy and shouldn’t be mistaken for science.

Something is rotten in the state of QED
February 2020

8 Summary
---
According Feynman,
“We have found nothing wrong with the theory of quantum electrodynamics. It is, therefore,
I would say, the jewel of physics — our proudest possession.”
But this statement is nothing more than a false myth.
The reality of the QED is better reflected by Dyson’s description in a letter to Gabrielse in 2006:
“As one of the inventors of QED, I remember that we thought of QED in1949 as a temporary
and jerry-built structure, with mathematical inconsistencies and renormalized infinities swept under the rug.
We did not expect it to last more than 10years before some more solidly built theory would replace it.
Now, 57 years have gone by and that ramshackle structure still stands.
” QED should be the quantized version of Maxwell’s laws, but it is not that at all. QED is a simple addition
to quantum mechanics that attempts to justify two experimental discrepancies in the Dirac equation:
the Lamb shift and the anomalous magnetic moment of the electron.
The reality is that QED is a bunch of fudge factors, numerology, ignored infinities, hocus-pocus,
manipulated calculations, illegitimate mathematics, incomprehensible theories, hidden data,
biased experiments, miscalculations, suspicious coincidences, lies, arbitrary substitutions of infinite values
and budgets of 600 million dollars to continue the game. Maybe it is time to consider alternative proposals.

It is all about grant money. If by some miricle something useful comes from playing with numbers, it is purely accidental.

Learning to Live in Steven Weinberg’s Pointless Universe
The late physicist’s most infamous statement still beguiles scientists and vexes believers
/ By Dan Falk on July 27, 2021 /
-----------------..
“The more the universe seems comprehensible,” he wrote,
“the more it also seems pointless.”

Why the universe is pointless for us?
Because we ignore the fact that the “big bang” can be started
only in the infinite Cosmic Vacuum

HOW EINSTEIN CHANGED PARTICLE PHYSICS
/ BRIAN KOBERLEIN /
"This equation is often taken to mean that matter and energy are two sides of the same coin. . . .
One of the simplest examples of this is electron-positron annihilation. "

CREATING MATTER FROM LIGHT
If you can convert matter entirely into energy, you should be able to do the reverse.
It’s known as the Breit–Wheeler process and involves colliding two photons to create an electron-positron pair.


In 1905, Einstein wrote a paper that was changed Particle Physics forever.
Einstein, E = mc^2
In 1927, Dirac clarified Einstein’s idea as dualistic particle: E=±MC²
(matter – antimatter are two sides of the same coin)
