Is there any hypothesis on what provides symmetry breaking for BB expansion and is there a definable model of particle stabilisation?

a) please provide acceptable standardised thermonuclear test confines. Standard drop height, velocity at detonation, fuel density at centre of momentum, energy released to the atmosphere and any factors involved I've missed that you believe are involved. b) if you could provide me with the material you accept as authoritive on the weak and strong forces I will be able to identify any further equation construction questions I will require guidance on.

This is not really a paradox or anything, but imagine this. If something would have created our universe like the big bang, what created the big bang? Another scenario, if god created us, who created god? And who created the creator of god and it goes on maybe even to the infinite. Another scenario, everything was possibly created by the big bang and that was probably near the dawn of time. But what created the dawn of time, when was the dawn of time? Maybe our universe was created infinite years ago, but thats impossible, that means that there was no start at all. This is really confusing... for me at least, all those people out there would probably pound me down on my h…

I have read accounts of the separation of virtual particles at the event horizon with the anti-matter particle falling into the hole, and the matter particle escaping, forming the radiation and allowing a net loss to the BH. Why does the reverse not happen as frequently with the anti-matter escaping into space and the matter particle falling into the BH, with the effect of increasing black hole mass? I had presumed the energy loss to the black hole was the "work done" to separate the particles, and the infalling number of anti-matter and matter particles would average out numerically in a cancellation effect. Plus, I read that region bounded by the inside the event horiz…

String theory has literally opened up a can of worms with it's postulate that space-time is 11 dimensional ( 10 space + 1 time ). Why couldn't we have more than 1 dimension of time ? I don't see why that is not possible. Would that turn conventional physics on it's head?

This is pure conjecture but I was thinking about it and wanted to ask people who know more about tachyons than I do: In a vacuum: Particles with mass can only travel with v < c Mass-less particles can only travel with v = c Tachyons can only travel with v > c If you refract light by passing it through a medium with a refractive index > 1 it slows down. I have heard of experiments where light is slowed to virtually a complete stand still, so my question is this: What would happen if you can slow a tachyon down to the speed of light? Would it give up its energy and instantaneously create mass-less particles? Or does that violate the laws of physics? If it did c…

If an extremely powerful electro-magnet is switched on, how quickly would it's most distant field of reach be active?, with say a magnet that could reach 13.8BLY?

Is the Higgs boson an indivisable particle like the photon , or might it have an internal structure?

I've just read an article on the BBC website (see link below) in which experimentalists have reduced the speed of light by remodelling photons. Does this mean that the frequency of light is also reduced? http://www.bbc.co.uk/news/uk-scotland-glasgow-west-30944584

How permeable do you think the "air gap" between tachyon particles and slow particles are to energy transmission? i.e. tachyon particle waves incidentally interacting with our lame by comparison slow particles. self.askscience If the below is too long feel free to pretend it doesn't exist. I'm just providing further context into the question if anyone is interested. So energy travels through particles via waves. And since particles have mass, with the exception of photons, the velocity of any wave when measured by particle velocity would never exceed c, right? But if tachyon waves do exist would it be possible that even if only in limited circumstances, such as when par…

Because gravity, space/time, special relativity, (and effectively light(speed)), and mass are all related, I've been thinking... It's said in an example that (simply put), a rocket ship from earth (containing people) is sent out at almost the speed of light to 4 earth-lightyears away, and then comes back. (in this example, acceleration and deacceleration is instantaneous) 4 years go by on earth, but for the people on the rocket ship, it's only a few weeks (or something like that). It was said that it's because the clocks of the space ship people slow down (in the view of the people of earth), and/or because the distance the rocket people are traveling shrinks at high sp…

From the Kaluza-Klein theory on wikipedia From the intro From the chapter Group Theory Interpretation There is my question(s): If we are understanding our world as four dimensional (3D of space + 1D of time) and we observe nowhere the 5th dimension, why do we suppose that the extra 5th dimension is compacted? In my understanding, the 4 dimensions should interpreted as a section into a 5 dimensional world. IOW that the 5th dimension would be of higher degree than what we actually observe. The 4D would then be embedded into a 5D reality. That is what we do when we describe a 2D world from a 3D: we make a section, or a projection. Something like a map.…

'Reinterpreting dark matter: Could dark matter be regarded as a very cold quantum fluid?' http://www.sciencedaily.com/releases/2014/07/140702092358.htm "As the Ikerbasque researcher explained, "guided by the initial simulations of the formation of galaxies in this context, we have reinterpreted cold dark matter as a Bose-Einstein condensate." So, "the ultra-light bosons forming the condensate share the same quantum wave function, so disturbance patterns are formed on astronomic scales in the form of large-scale waves."" The ultra-light bosons forming the condensate share the same quantum wave function, so disturbance patterns are formed on micro scales in the for…

Does the nature of what we call the laws of "physics" have a history? For example in biology we talk about how proteins evolved into a macromolecule, into an organism unit or simple cell, into a complex cell or more complex prokaryote, into a multicellular organism and such.. In chemistry obviously we talk about how matter became massive and how massive particles started evolving out of the initial hydrogen, helium, and the reactions that have generated all that we see before us. But for some reason people think that the laws of physics or the nature of physics have always and will forever be constant.. what if they weren't and are not static?

A few years ago i finally got to know of string theory and it accrued to me that it seemed like particle DNA. Are there particles that replicate? Can we find ways to affect the particle DNA as we can effect our bio DNA?. What other parallels can be drawn to help figure it out. This is just a theory and probably a naive one at that. Thanks for your time and space. After readiing more on this site you better move this to speculation.

What drives the universe through this thing that is called TIME what exactly is it?? I mean what are we measuring using all these clocks?

Theorisations over the Higgs Boson, and M-Theory, both have an ultimate aim in helping reach a 'Theory of Everything'. However, if one day soon scientists were able to prove that one of these 2 theories is correct, would that necessarily disprove the other? i.e. Could a Higgs-field manifest itself in a string-based Universe? Or would it be even needed? (and vice versa..)

In terms of its source, fundamentally an accelerated or oscillating charge. What is a formula to describe the acceleration of the charge and frequency of electromagnetic radiation produced? A formula or some sort of HELPFUL link would be great thanks.

There is magnetic and electric dipole. The word itself "dipole" is very ambiguous to me. Also "dipole moment" (my guess it it is just a pause in a frame of time depicting the fields or just capturing that moment, something like that)?

when an object like a car is fabricated atoms are co-related to form components. Altough energy is expended through losses what about the final product - the car. It is in an ordered state and its entropy has decreased (since it is well ordered). How do we explain this overall? Even in the universe entropy is increasing, as we all know. So where does this fit in?

Hi there! I try to understand and to use graphical method in the theory of angular momentum. It is not very difficult to master is fundamentals excepting a few things. The most fundamental is the following. In literature there is used the fact that Kat and Bra vectors with momentum j,m can be mutually permutated using <jm| = (-1)j-m |j, -m>. It is clear for integer j. But how to understand this fact, for example, in the case j = 1/2 ? I would be glad if somebody could give me advice. I'm absolutely novice at forums where scientific questions are discussed. So, first of all, I would be glad to see a few words about where else I can discuss such questions. What ci…

I have done quite a bit of research on this, and my friend and I are at a disagreement. As we physically cannot get a particle to absolute zero, as that would require us to get every particle in the universe to absolute zero, I am asking whether this could be theoretically possible. Here is what I currently know: Temperature is the measure of heat (obviously), which is the measure of the speed that particles have (these are basics that I didn't need to research at all). The particles therefore would have to have negative speed. But, as I thought about it, the speed of particles would tell how much energy they have. Energy is linked to the electrons. So, a soli…

I know that the Big Bang theory came to be after Edwin Hubble discovered the expanding universe. Since the universe was expanding, it had to originate from one point back in time. What caused the universe to expand? was it the energy from the dense universe? or perhaps the compacted universe was but a star in a sea of universe, and there was a force that acted like anti gravity, pulling the atoms away from each other. Was it that the individual atoms expanded away from each other? I read on a physics forum someone say, that the universe is not really 14 billion years old, it is 14 billion years from the oldest time our theories can make an accurate prediction.…

Which are better to ionize particle between Van De Graff Generator and Tesla Coil? I know that; For voltage is Van De Graff and for electrical current is Tesla Coil. And I heard Van De Graff Generator have been used for a linear particle accelerators and also tesla coils for ionizing particles like hydrogen. Summary 1. How the van de graff generator used for a Linear Particle Accelerators? 2. Which are BETTER ionizing particles between van de graff and tesla coils?

What if the smallest unit of space is a granular point, measuring one Plank's length in every possible dimension? This would cause a string to be pan dimensional as well, measuring one Plank's length in every possible dimension, and capable of vibrating in the direction of any dimension. It makes no sense to assume that space is capable of behaving like the mathematical concept of dimension. It makes no sense to assume that space can be purely one or two or three dimensional. If the smallest unit of space is redefined as being composed of pan-dimensional granular points it allows for a fascinating series of extrapolations that might better explain the observed dat…
