What you think of Scale Symmetry?

In summary, according to this article, scale symmetry is a key to understanding all of the latest findings in particle physics. It is a departure from long-standing assumptions about how particles acquire their properties, and it has recently resurfaced as a common theme of discussions among respected particle physicists. With scale symmetry broken, masses and lengths spontaneously arise. Supersymmetric particles may be within reach of the LHC, and perhaps of Fermilab, since the supersymmetric approach to the hierarchy problem doesn't make sense if they are too heavy. There is huge potential for further discovery with scale symmetry, and it would be interesting to hear your thoughts on it.

After 3 hours of google search. I found out scale symmetry is related to dimensional transmutation that can replace the supersymmetric particles that can solve the Hierarchy Problem of the Higgs (this is the hottest thing in LHC and physics right now). Scale symmetry is the key to understand all this. There is almost zero hit about scale symmetry in Physicsforums so let me share the details and the questions. The following article is directly connected to the Sci-Am article on Hierarchy problem and dimensional transmutation https://www.quantamagazine.org/20140818-at-multiverse-impasse-a-new-theory-of-scale/

quoting...

"This little-explored idea, known as scale symmetry, constitutes a radical departure from long-standing assumptions about how elementary particles acquire their properties. But it has recently emerged as a common theme of numerous talks and papers by respected particle physicists. With their field stuck at a nasty impasse, the researchers have returned to the master equations that describe the known particles and their interactions, and are asking: What happens when you erase the terms in the equations having to do with mass and length?

Nature, at the deepest level, may not differentiate between scales. With scale symmetry, physicists start with a basic equation that sets forth a massless collection of particles, each a unique confluence of characteristics such as whether it is matter or antimatter and has positive or negative electric charge. As these particles attract and repel one another and the effects of their interactions cascade like dominoes through the calculations, scale symmetry “breaks,” and masses and lengths spontaneously arise.

... (continue quoting)

The scale symmetry approach traces back to 1995, when http://theory.fnal.gov/people/bardeen/wbardeen.html?__hstc=13887208.fd3fbbf9f7855dfcee679370f812aa59.1472103875706.1472103875707.1472288820401.3&__hssc=13887208.2.1472288820401&__hsfp=559246593 , a theoretical physicist at Fermi National Accelerator Laboratory in Batavia, Ill., showed that the mass of the Higgs boson and the other Standard Model particles could be calculated as consequences of spontaneous scale-symmetry breaking."

What do you make of it? If scale symmetry and dimensional transmutation is unlikely.. then the solution to the Hiearchy Problem with missing supersymmetric particles may be Multiverse which is extremely excess baggage.. so scale symmetry may be the Occam Razor's.

In http://arxiv.org/pdf/hep-ph/0207124v1.pdf, Edward Witten stated:

"We can hope for much more beyond the Higgs. Supersymmetric particles should be
in reach of the LHC – and maybe of Fermilab – since the supersymmetric approach to the
hierarchy problem does not make sense if they are too heavy."

There is huge possibility there is no supersymmetric particles because the not too heavy sector is already excluded by the LHC searches. This is also for the extra dimensions. So with two possibilities for the solution of the Hiearachy Problem very high probably excluded. We have Multiverse and Scale Symmetry options. Multiverse is excess baggage. So actually the only two real possibilities left are scale symmetry or intelligent design. If you don't like intelligent design, then Scale Symmetry is the only real possibities. Even one of the world's greatest mathematician Peter Woit agreed. So can't anyone talk about Scale Symmetry? Or secretly do you physicists are really subconsciously into Intelligent Design now as the solution to the Hiearchy Problem?

Here's an interesting article on scale symmetry and gravity, or more specifically "agravity." I would welcome any thoughts you have on it. As an aside, the paper also talks about the weak force and QCD couplings, among others, so very far ranging indeed.

1. What is Scale Symmetry?

Scale Symmetry is a concept in physics that refers to the idea that the laws of physics remain unchanged when measurements are scaled up or down by a certain factor. This means that if you were to double or halve the size of an object and observe its behavior, the laws governing its movement would remain the same.

2. How is Scale Symmetry related to the laws of physics?

Scale Symmetry is closely related to the laws of physics, as it suggests that these laws are universal and remain the same regardless of the scale at which they are observed. This concept is fundamental to our understanding of the physical world and is a key principle in many branches of physics, including particle physics and cosmology.

3. Is Scale Symmetry a proven concept?

While Scale Symmetry is a widely accepted concept in physics, it is not yet fully proven. As with many theories in science, it is constantly being tested and refined through experiments and observations. However, the evidence gathered so far strongly supports the idea of Scale Symmetry and it is a key component of many successful theories and models.

4. How does Scale Symmetry impact our everyday lives?

Scale Symmetry may seem like a very abstract concept, but it has many real-world applications. For example, it helps us understand the behavior of objects at different scales, from subatomic particles to galaxies. It also plays a crucial role in engineering and technology, allowing us to design and build structures and systems that function consistently and predictably regardless of their scale.

5. Are there any exceptions to Scale Symmetry?

While Scale Symmetry is a powerful concept, there are some cases where it does not apply. For example, at very small scales, the laws of quantum mechanics take over and can lead to unpredictable behavior. Additionally, in extreme conditions such as near black holes or during the early stages of the universe, other fundamental forces may come into play that can disrupt Scale Symmetry. However, in most everyday situations, Scale Symmetry holds true and is a valuable tool for understanding the world around us.
