A: The background

In the past 40 years, the HEP (high energy physics, the foundational physics) is solidly based on the SM (Standard Model) which is a phenomenological model (with many free parameters), also based on Higgs mechanism.

In the theoretical front, there are some key issues.

One, Naturalness (restraining the Higgs boson mass; resolving the hierarchy issue).

Two, SUSY (with s-particles), the solution for naturalness.

Three, Cosmic Inflation scenario to eternal inflation to Multiverse (dodging the mystery of the nature constants issue, claiming that the nature constants (CC, Alpha, Higgs boson mass, Planck CMB data, Cabibbo/Weinberg angles, etc.) of THIS UNIVERSE are all environmental and cannot be derived.

Four, black hole information paradox.

Five, how to construct the quantum gravity.

Yet, all the issues above seemingly could be resolved by M-string theory, as:

SUSY is the direct consequence of M-string.

Multiverse is the direct consequence of M-string.

The black hole entropy can be calculated by M-string.

Graviton is the direct consequence of M-string.

That is, the M-string theory is the only TOE (theory of everything).

B: The dissidents

However, there are a few (very few) disagreed with the M-string’s claim in the mainstream HEP community.

In the 2004, Peter Woit and Lee Smolin disagreed with M-string’ claim with two reasons.
M-string is just a framework of ideas (not well-defined theory),

and thus, it cannot predict anything while explain everything.

So, it is a pseudo-science.

While Peter Woit keeps up his anti-M-string campaign, Lee Smolin drifted off.

Around 2015, Sabine Hossenfelder kind of joined this dissident group while her key disagreement is on the Naturalness issue without openly denouncing the M-string.

Also, around 2015, Paul Steinhardt (the inventor of ‘inflationary cosmology’) began to distance himself from what he had invented.

In addition to this dissident group is so puny, they are criticized for their big shortcomings:

{they just disagree without anything new of their own).

So, M-string is the ONLY game in town STILL.

C: The dawn

The first light:

On June 4, 2021, Peter Woit stated: {If a highly complex and obscure set of ideas accurately computes the details of something you can observe, you know there is something right about it, even if you don’t understand the set of ideas.} See https://www.math.columbia.edu/~woit/wordpress/?p=12353#comment-238968

Obviously, the {ideas accurately compute the details of something you can observe} refers to the followings: (Alpha, CC, Higgs boson mass, Planck CMB data, etc.)

See https://twitter.com/Tienzen/status/1401602348393238531

The second light:

Peter Woit published his {Euclidean twistor Unification theory} and gave a lecture at Brown University on September 23, 2021, see the video (https://www.youtube.com/watch?v=wNK_JxK0s9E&t=115s ).

After being a dissident for the past 20 years, Dr. Woit is putting out something new of his own.

The following is some background about his new work.

Einstein’s GR (general relativity, a gravity theory) is based on Minkowski geometry while the SM (QFT) was written with Euclidean geometry.

So, the difficulty of unifying GR with quantum (SM) is caused by some irreducible difference between the Euclidean geometry and Minkowski geometry.

Then, there is another issue, the {imaginary time} which was used in physics in two ways.

One, as the mathematical convenience for physics calculation, without any physical meaning of its own.

Two, as a novelty at the point (or before) of the big bang while it is not a part of space-time after the big bang.

In Dr. Woit’s new work, he tried two things.

One, projecting both geometry (Euclidean and Minkowski) into twistor space.

Two, adding a distinguished imaginary time direction into Euclidean twistor space, then the difference between Euclidean and Minkowski can be bridged, that is, a geometrical unification. And thus, the Gravi-weak unification becomes possible.

My words to Dr. Woit:

D: The evening twilight

Planck’s principle”: “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”

This evening twilight is ensuring that the dawn of this new HEP era is, in fact, here.
