This is an introduction to modern physics, assuming the basics of calculus known. We first review the foundations, namely classical mechanics, relativity theory, electromagnetism and thermodynamics. Then we make our way through quantum mechanics, starting with early thoughts, experiments and results, up to the standard basic formalism, still used nowadays, and with a look into quantum electrodynamics too.

This paper introduces a novel physical model based on redefining the energy structure of the universe as the primary engine behind the manifestation of spacetime and relativistic effects, without presupposing time and space with their classical units. We reformulate photon energy relationships using Planck natural units and derive time dilation from a variance in energy ratio between environment and medium, where perceptible spacetime is the result of the difference between pure theoretical energy and observed effective energy. We propose that the interaction between accessible and constrained (dark) energy gives rise to spacetime itself. A computational model is introduced to calculate spacetime effects purely from energetic parameters. We also propose a generalization of the Heisenberg uncertainty principle within this structural framework.

This short paper presents a radical view about time asymmetry.It will be argued that if one reduces the notion of time to nothing but the order of events,then quantum mechanics, via non-commutativity, gives a plausible explanation as to why physicalprocesses unfold in one direction and not the other.

Life is proposed as being more expansive in terms of reach and capability than currently understood. Aspects of life are presented suggesting it should be considered as a distributed intelligence that has established structures and designs in the realms of computation/information, memory/quantum mechanics, and even consciousness, before these realms were discovered by modern intelligent humans. The nature of consciousness is discussed in depth, referencing specific research including advances in renormalization techniques that imply consciousness exists at a fractal critical point in the brain and that consciousness is most likely fractal and holographic and exists on a space-time boundary where consciousness and memories are stored and operate external to the human mind, analogous to cloud computing. A "grande vista" of life conceptual framework is proposed noting life’s progression of "existential leaps."

1. We prove a theorem that says, essentially, that it is impossible for an infinite slab to exist which absorbs, reflects, or transforms a fraction>0 of the energy in weak gravitational waves. But it is (essentially) possible to make a 100% efficient emitter of such waves.2. We prove a theorem that says, essentially, that General Relativity (GR) is soluble forward in time but not backward in time, in a manner like the 1D "heat equation" Ft = Fxx.3. We discuss other (known) time-direction asymmetries of GR. All of these ultimately arise, essentially, from the positivity of mass.Hence we argue that, contrary to common false claims, gravitational physics is not time-reversal invariant and defines a unique direction of time as an output not input. Making this argument involves re- solving several subtle apparent paradoxes. But non-gravitational physics (quantum field theories) obey charge-parity-time reversal invariance CPT. We conclude with the grand Manifesto that all the time-irreversibility phenomena observed in everyday life, including "quantum measurement," the 2nd law of thermodynamics, and outgoing-only radiative boundary conditions, ultimately arise from gravitational physics. We outline how that happens and discuss the implications about future quantum gravity theories.

The time we perceive in everyday life is a normal concept but there is still no real answer to what is time? It is difficult for us to imagine that our minds and perceptions are placed in a universe with a huge amount of matter and extremely bustling events. This research designs a fictitious but feasible λ closed universe model. In this universe everything seems very simple, there exists only one mathematical entity called the entity σ and there is absolutely nothing else besides this entity. All events occurring in the universe λ are caused by the behavior of entity σ. The signal diagram is a time axis to measure time in λ. When the entity σ exists at a time on the time axis, it is clear that the previous times are all past times of σ in λ and the time domain. This time is called the time domain P. So let's assume entity σ can enter the time domain P on the signal diagram and then analyze how the state of λ will change. According to the butterfly effect, every small impact also creates big changes. The impacts of the entity σ in the time domain P, whether large or small, also create events that are different from the events that happened in λ, even the fact that σ exists in the time domain P is an impact. Because those event changes have created a different universe than the original universe, applying the multiverse theory, it can be said that σ entering the time domain P means σ entering a parallel universe. But it is still not possible for σ to enter a parallel universe, but research has come up with a method called the λ synchronous method. Because of the special properties of the closed universe system λ and the entity σ, it is entirely possible to create another closed universe system exactly like the original system, then all the events in the original system λ are recreated in the new system λ and adjusted so that events in the new λ begin to occur a period of time later. At this time, let the entity σ jump to the new λ system and one thing has completely happened: the entity σ has entered its own past. When using this method to let σ enter the time domain P, we can see that the time in the original λ system and the new λ system are events that occur in λ itself, when no events occur, or we can say when the entity σ is at rest, time is also considered to be standing still. Only when σ moves to create events can we feel the existence of what we call "time". So when we gather all our minds and perceptions into such a simple closed system, we can envision two answers to two problems. Firstly, traveling to the past is just going into another parallel universe and wanting to go into another parallel universe is completely feasible but on an extremely small scale and simple until the present times. Second, time can simply be the movements that make up events. If we consider the entity σ as a bit of information, then the λ synchronous method of bringing σ into the time domain P can also be used to store and communicate information in a new way. One can imagine how exciting it would be to be able to project bits of information into one's own past and influence to change information that happened before.

Computational models of physics suggest reality operates via a fundamental update rule, yet they lack an explicit physical mechanism for its instantiation. Constructor theory mandates that any reliable transformation requires a physical constructor. This paper resolves this gap by proposing the 'feme' — a fundamental replicating information structure — as the necessary constructor.We frame the fundamental update rules, such as those described in Wolfram Physics or supersymmetry, as the transformations caused by the interaction of the feme with reality. We argue that femes, like genes, memes, and temes, are replicators that embody knowledge for creating both a phenotype and a copy of itself. Their evolution by natural selection provides a causal mechanism for the stability and fine-tuning of physical laws, predicting observable signatures including a self-replication program, embedded error-correcting codes, and the fallibility of physical laws.
