I had a thought and felt compelled to jot it down before I forget it. It’s not yet very well thought out so I’m going to write things down as they occur to me. Apologies in advance if this post becomes a bit messy.
The topic is the universe, its origin, the possibility of other universes and their relation to quantum mechanics. As some of you might know, I’m a big fan of the zero-energy universe. The idea that something cannot come from nothing is an idea that has become outdated due to quantum mechanics. As Lawrence Krauss said “If you observe nothing for long enough, something will appear”. What he is refer to is known as quantum fluctuations.
Quantum fluctuations are a phenomena where if you have a vacuum with absolutely zero particles and energy in it and you observe/measure it over a period of time, you’ll find that something does in fact appear out of this nothingness. These are known as virtual particles and without getting technical, basically they appear and disappear in the nothingness leaving real energy signatures that affect their surroundings. Essentially, we are getting energy out of nothing. Now I’ve heard people argue “oh, well that’s not nothing then”. A debate on Q&A comes to mind and as usual, it was a theist trying to cast doubt on science (rather hypocritically). I’ll save that rant for another time, but suffice to say if you have a vacuum with nothing in it – that’s nothing. You can’t say it’s not nothing because the nothing you’re trying to describe doesn’t exist. When you find evidence of such a nothing existing, you can come back and say something. Old habits die hard – these people love claiming things exist without any evidence.
So how does this tie in to the universe? Well quantum mechanics still hasn’t been unified with general relativity, but it does provide an explanation for the origins of the universe. The zero-energy universe is one such idea, but the gist of it is that a singularity (from which the big bang and universe occurred) is so tiny that it falls within the realms of quantum mechanics. As a result, it doesn’t violate any laws by appearing out of nothing. Quite simply, the universe could have created itself out of nothing.
That got me thinking – why did the singularity keep expanding rather than dissipating and leaving an energy signal like most other virtual particle? The go-to answer for expansion is dark energy, but drawing from the Poplawski universe model and the torsion-rebound theory, I thought of another possibility.
What if all virtual particles contain universes? What if quantum fluctuations are a universe birthing mechanism?
Well, obviously the next question is, how does this work? I’m not going to sit here and claim things without providing proof – that would make me an idiot.
Let’s go through it step by step. At first, we have a singularity. Where did it come from? For this concept (I say concept because a scientific theory has been tested mathematically and experimentally, which I cannot do) we are considering the possibility that the singularity, as a subatomic particle, appeared via a quantum fluctuation as a virtual particle. Now from what we already know, this singularity exploded, known as the Big Bang, releasing large amounts of energy and expanding well beyond the speed of light. Here’s where my idea reaches a fork and would require further research.
First, we consider that virtual particles do release energy. The argument would then be made that these energy levels are tiny compared to the big bang. However, one must also consider perspective. From our universe’s perspective, the energy released by the virtual particle is small, but if that virtual particle contained another universe, relative to them, that amount of energy would be the absolute maximum they could ever attain. This gives rise to the idea of a staggered multiverse, where there are greater universes with more energy and vice versa.
Second, (consider this a different option unrelated to the one above) the effects of travel beyond light speed is unknown. However, if one considers the virtual particle contains a similar universe to ours (i.e. of similar energy levels, and thus similar mass, and thus similar gravity), then the moment that virtual particle experiences a “Big Bang” it has reached levels of gravity many times that of a black hole and is inflated beyond the speed of light. From the outside nobody knows what that would look like. But we can take a good guess. Black holes are known to distort time. We can never peer into a black hole because the gravitational tides distort both light and time. As a result, we can never travel out of one if we get caught in its event horizon. In essence, the inside of the black hole is almost like a separate universe to ours – we cannot see inside, journey inside or journey out of (if we ever got in), and time freezes as we approach its singularity. Additionally, time slows as we approach light speed. Theoretically, at light speed time would stop so an external observer could stare at you for an eternity and never see anything. Again, this has the effect of isolating something from the rest of the universe – you become unobservable because time has stopped.
What if the same were true for virtual particles? If it contains a universe, its gravity and speed of inflation would separate it from our universe. The small energy signature could be residual or leakage from the contained universe. A black hole releases radiation (Hawking Radiation) so that is a detectable verification of this idea, but one would say a black hole’s radiation is much higher than that of a virtual particle. Well, a black hole isn’t expanding faster than light – it’s shrinking. Combining the gravity and the inflation could potentially have the effect of not only isolating the interior from the rest of our universe (as a black hole does) but displacing the entity itself from our dimension. Essentially, the moment the virtual particle disappears (leaving behind a weak residual energy signature) it has experienced its Big Bang and as a result, has separated itself into its own dimension, creating a universe with it. Alternatively, it could be in the same dimension, but due to the isolating effect of gravity and super-light-speed travel, we cannot observe it, nor can it affect us.
It’s not new to say that the universe created itself out of a quantum fluctuation, but it should be new (unless somebody thought of this before me again – just like with the Poplawski theory) to say that quantum fluctuations are in fact creating universes and we are in fact seeing that happen when virtual particles appear and disappear. Not only does this build on an existing theory – the zero-energy universe model (and thus all the evidence, research and experimentation that has gone with it), but it bridges the gap where one could ask how this universe continued to expand when most virtual particles disappear and leave energy behind.
The exciting thing is this is testable to some degree. Many string theory supporters have been hoping the LHC will launch a particle at sufficient energy levels to send it into another dimension. Basically, the particle would “disappear” and we’d have a missing energy signal. If we do achieve this, that would potentially be evidence of further dimensions and be a whole new platform for us to work science on.
I think I should also mention at this point that Dr. Tyson mentioned something somewhat related to this topic. He asked that if it was possible that someone was launching particles from another dimension (like we would at the LHC) and they are appearing in our dimension as quantum fluctuations. This was during the 2011 Isaac Asimov Memorial Debate for those interested – entertaining to watch, just YouTube it.
Well, I would like to rephrase his point because it was sort of laughed off as a joke. What if it wasn’t “someone”? It’s entirely likely that higher dimensions have higher states of energy. For example, their universal constants might have a higher value and their speed of light could be greater or it could be possible to exceed light speed. In that case, it’s entirely likely that such an occurrence could happen naturally. No, not someone launching particles into our dimension – just a natural occurrence at higher energy states. This would provide an interesting approach for string theory scientists, as well as address the mystery of quantum fluctuations.
Anyway, that’s my random shower-time theory. It’s been a while since I’ve had one of these but it always gets me excited when my brain starts trying to connect separate pieces of knowledge that I’ve acquired.
