  1. Yes, if we replace the word “nothing” with “vacuum” in the question, meaning a physical vacuum. The creation of matter (an electron or positron) from a vacuum can actually be observed by the radiation (evaporation) of black holes near the event horizon. This radiation is called Hawking radiation. In quantum field theory, vacuum fluctuations are expressed by the constant generation and annihilation of pairs of virtual particles. In the field of external forces (for example, gravitational), the dynamics of vacuum fluctuations change, and if the forces are large enough, particle-antiparticle pairs (for example, the e⁺e⁻pair) can be generated directly from the vacuum. Such processes can occur near the event horizon of a black hole. In this case, it is possible that one of the particles falls inside the black hole, and the other becomes available for observation. Due to these processes, the mass of the black hole decreases. But it should be noted that so far the Hawking hypothesis has not been confirmed by observations due to the lack of sensitivity of our detectors. Note also that there is an assumption that vacuum fluctuations were also responsible for the origin of our universe.

    Another effect of vacuum fluctuations, which is already observed in the experiment, is the Casimir effect, where the generation of virtual photons in the process of vacuum fluctuations leads to a measurable attractive force between two closely located parallel uncharged gold plates. The effect was predicted in 1948 and recently (1997) confirmed experimentally with a 99% probability.�

    So, science is silent about the birth of matter “from nothing”, but science does not prohibit the possibility of the birth of matter (radiation) “from fluctuations in the physical vacuum”.

  2. Not if something is simple from molecules and atoms. But I have another question is it possible to create something very solid from some substances. Whatever it is, it can repel or protect you from any blows.
