Time's Arrow - Part 2

Released: May 9, 2026 8:00 AM CST

Here is the thirty-ninth episode of Quantum Foam, Time's Arrow - Part 2. There needed to be another part to this topic. The Big Bang Theory was a pretty good TV show. Ludwig Boltzmann committed suicide. Constantin Carathéodory was a Greek mathematician who made significant contributions to real and complex analysis. He created axiomatic descriptions of Geometrical Thermodynamics. We know that time goes forward. Going backwards in time is something we have considered. According to General Relativity, we think that such a thing may be possible. Time can be described with propositional logic. We are ruminating about the symmetry and asymmetry of time. Time may be irreversible. We know that entropy increases as time goes by. This is dealing with states of disorder, randomness, and uncertainty. Each episode of the Quantum Foam podcast is a 1-day lecture on a subject or idea. Isotropic means to be equal or have equivalent properties on all sides. It is built within each part of the system. Consider anisotropy as well. It varies systematically. A well-known spacecraft was the Wilkinson Microwave Anisotropy Probe. It used this type of system. The Second Law Of Thermodynamics is especially important. Hawking Radiation is black-body radiation outside of a Black Hole event horizon due to quantum effects. We want to keep track of the second law and how it relates to Holography. This is a property of quantum gravity. Weak Nuclear Force interactions are asymmetric to the reversal of time. There's one direction when you do nuclear physics involving beta decay and other weak interactions. We go forward in time due to our relative proximity to The Big Bang.

What is the inverse of time? What is the opposite of time? The opposite of time may not make sense, but the inverse of time is 1 divided by time. We observe events unfolding in 1 direction. Time moves forward because of entropy. There is a clear distinction between past and future. We can model a graph of our universe. If you superimpose a graph of a slice of our universe, we are located at a foci that is 13.77 billion years after The Big Bang. It is toward the right down the x-axis, so that means that we are forward in time that far down in time since the beginning of our universe. This is a way to model time on a graph relative to everything else. The Hilbert Space that is the universe is first written as being set equal to 0. On the graph, 1 direction is negative in time, and 1 direction is positive in time. According to our understanding of physics, there are things that make it harder to go back in time due to irreversibility and asymmetry. The psychological Arrow Of Time is a list of contiguous events, 1 after another. This is interpreted by our brains and intellect. What we have is a known past and an unknown future. The present volition is what determines future events. The perceptual Arrow Of Time deals with our memories. There is no influencing the past. Time is a very important topic. We can recall durations. Time travel to the past still remains highly speculative and is not currently achievable. We may possibly share our subjective experiences using neural technology. In other words, this is our sense of time. Time can be seen as a mathematical quantity that measures the duration of an event. We go over this subject every decimal of the show. It is important to pay attention to our history. This time around, we had 2 whole episodes relating to time.
