On a very small atomic scale, matter can come from nothing.This process is called a quantum fluctuation-Wikipedia in which particles emerge from the nothingness and disappear very quickly.This is a process that takes place everywhere in the universe, even in the empty space. The particles disappear so quickly that the space appears empty. But with experiments such as the Casimir effect-Wikipedia can prove the presence (the effects) of those particles.
In a completely empty universe these particles will emerge and disappear but never let planets or stars arise.Now there is a theory Eternal inflation-Wikipedia in which in an empty universe after a long wait (10 to the Power hundred years, a 1 with 100 zeros) sometimes a “inflaton” virtual particle is not.This particle has the special feature of letting the room out and letting energy arise to create real particles such as quarks and photons. It is thought that such Inflaton is the cause of our universe.
Matter cannot be made out of nothing.As Henk Koppelaar already indicates, you can use energy in order to make matter.That is also what happened in the genesis of the universe.
My vision is as follows:
The reality we observe is a constant movement from a concentrated hot situation to a 芒 鈧?虄entropische 芒 鈧劉 cold situation.By this I mean that everything in the universe is moving. Energy is by definition movement and also all the energy that has a physical effect is in motion (the load of atoms at-273C is not silent, but is going to be slow). Eventually, all energy will become so鈩?low speed that it becomes matter and if that matter eventually loses its internal speed, it will lose its cohesion. Now there are two possibilities: the whole attracts each other (but attraction is also energy/movement dependent) until it forms a singularity, in which everything finally comes to a halt again, until a 芒 鈧?虄critical Mass芒 鈧劉 moment is reached And even the smallest overpressure for a chain reaction ensures and a new universe is born (actually a new version/configuration). OR everything goes out and that is it. Oh well, there may be many more options, but these are the main lines.
Matter can arise from non-Material energy, such as electromagnetic radiation (where our visible light is also part of it).
But because our universe is always in keeping with energy preservation of momentum, this cannot originate from 脙 漏 脙 漏 n some photon.
This is because there is always a frame of reference in which the photon in question has too little energy to be able to Create the resting mass of the massive particles (a reference framework that 芒 鈧?艙meereist芒 鈧?in the direction of the photon).
But as soon as two photons meet, there is a unique frame of reference in which these two photons contain the least energy.There is always more energy for every other frame of reference.
If this lowest energy reference framework contains sufficient energy for the mass of the particles, this can occur in this situation:
This has been reproduced under laboratory conditions.
Time expires from left to right and one dimension of space is placed in the y-axis. Two photons meet and Create an electron and a positron.
Here is with arrows indicated that the positron can also be seen as an electron that is 芒 鈧?艙back in time motit芒 鈧?
Very curious for our senses:
Exchange with the VACU脙1/4m causes that.
For example: You shoot a small amount of energy to an atom.That causes an increase in one of the energy states of an electron in a orbit and at the same time a light particle from the atom shoots outward.
That light particle (photon) comes from the vacuum around the core.
This exchange with the vacuum is the reason that Hawking invented the radiation mentioned to him around black holes.We also know this radiation as a fire, i.e. light particles as a by-product for oxygen conversions, or combustion.
Matter cannot be made out of nothing, but from the vacuum, the empty space.The theoretical possible energy density (Planck density) of the vacuum is enormous, much closer than that at the beginning of the Big Bang. The vacuum now looks stable, but it is possible that it may even further lapse to a lower energy level.
How can that be?That is determined by the properties of the space-time in which we live.
The (absolute) nothing is unstable, so from this absolute nothing can arise, among other things, time, space, energy and matter.
Edit: Of course, not yet a really 100% satisfactory answer, but here we have to do it now.. 😉
