Did a Higgs Boson trigger the big bang?

Click For Summary

Discussion Overview

The discussion centers around the claim made by Michio Kaku that the Higgs Boson may have triggered the Big Bang. Participants explore the implications of this idea within the context of cosmology, quantum gravity, and the nature of the early universe.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about Kaku's credibility, suggesting that his recent popularization efforts may undermine the scientific validity of his claims.
  • One participant notes that the concept of something 'triggering' the Big Bang is problematic, emphasizing that the Big Bang represents a hot and dense state rather than an event that was triggered.
  • Another participant introduces the idea of the inflaton, a particle theorized to be involved in the early universe's inflationary phase, suggesting it may be more relevant than the Higgs Boson in this context.
  • There is mention of the Higgs Boson being considered as a candidate for the inflaton under certain theoretical modifications, although this is presented as speculative and controversial.
  • A later reply references a paper discussing quantum gravitational instability as a potential trigger for the universe's transition from a static state, raising questions about the completeness of Kaku's assertions.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of Kaku's claim and the role of the Higgs Boson in relation to the Big Bang. Multiple competing views are presented regarding the nature of the early universe and the particles involved.

Contextual Notes

Some discussions hinge on the definitions of key terms like 'trigger' and the nature of the Big Bang, which may not be universally agreed upon. The relationship between the Higgs Boson and inflationary theory remains unresolved and speculative.

Who May Find This Useful

This discussion may be of interest to those exploring the intersections of particle physics and cosmology, particularly in relation to the Big Bang and early universe theories.

I wouldn't trust anything Kaku has said in the last 10 years. He used to be a serious physicists (and QUITE a good one) but lately as become a popularizer of the worst sort. The fact that he said it doesn't MAKE it wrong, but it sure makes it highly suspect.
 
I watched it myself, and it seems very mixed up.

We don't know what began our Universe. It was likely in some state with strong quantum gravity, and quantum gravity is just plain hard.

However, there was likely a particle much like the Higgs particle involved in the very early Universe: the inflaton (no i). It's called that because it makes the inflationary phase of the history of the Universe, a period of exponential expansion that flattened it out and that froze into place quantum fluctuations as they got stretched beyond the event-horizon size.

However, the mass scale of the inflaton is something around 1015 GeV, which is much bigger than the Higgs particle's mass scale.
 
It doesn't make sense to say something 'triggered' the big bang. The big bang was the hot and dense state the universe was in, and it's evolution from that state.

The Higgs Mechanism doesn't have anything to do with that. It's function is to break the electroweak symmetry.

As phinds said, I wouldn't trust too many of Kaku's popular science videos.
 
If you listen carefully, he's saying that it was a 'higgs-like particle', not the higgs itself. I can only speculate, but I think he's actually referring to the inflaton here, since it, like the Higgs, is a scalar particle. Most of the other stuff he says in that video is nigh incomprehensible to me though...
 
Yes, and note that the SM Higgs is recently in vogue again as an inflaton candidate as long as you mutilate the theory by introducing large scalar couplings, whacky kinetic terms, and the like.
 
Michio Kaku (see link) says that the Higgs Boson is the reason for the Big Bang.

The author states:

. Some unknown quantum gravitational instability triggers the universe to make a transition from the initial static state, to one of increasing Hubble distance ...

It would be rather amazing if the author missed such a definitive reason for the big bang!
