The only constant of nature is change, and change is a direct consequence of interaction.

Matter has the property of absorbing and re-emitting photons, and the fluorescence spectrum resulting from this process can be measured in experiments and is a good indicator of the correctness of the modeling used in theory. With the advent of high power lasers, the fluorescence spectrum requires relativistic calculation. We can ask fundamental questions such as: are there p-adic contributions to the real ones? How does quantum measurements influence chaos theory? Do high power lasers bend spacetime? Do we live in a discreet or continuous universe?

Quantum mechanics provides us with valuable information on how we can treat multiphotonic processes. Also, due to the electroweak interaction between the nuclear constituents, the coupling of the nucleons to the atomic electrons gives rise to the effects of violating the parity. These fundamental processes underlie hot cosmic objects, but are also found in artificially produced plasma in laboratories. The Tokamak is one of the devices based on the plasma confinement process, designed for the production of thermonuclear energy.

Starting with the Noether theorem we have learned that conservation laws are related to symmetries and these to Lie groups. Field theory is the fundamental theory that underlies the understanding of elementary particles through symmetries. Which is more fundamental, the continuous space or the lattice? Quantum chromodynamics is built on three direct requirements of nature: confinement, mass discretization, and chiral breaking of symmetry. If the first two requirements can be described on lattice, the last one needs continuous spacetime. Is time on a time-scale the most fundamental?

What is vacuum? What existed before the vacuum? Field theory teaches us that it represents a continuous fluctuation of particle-antiparticle pairs, whose infinite contribution to energy we always extract from calculations. Is there a quantitative description of the vacuum? Being a light propagation medium, aren't there extreme conditions in which they influence it? The model of the inflationary universe requires superlight speeds immediately after the big bang occurs. Supernova explosions are the laboratory in which the laws that describe the speed of variable light can be studied.
