What is time? Speaking time travel, black holes and the remits of science. In this podcast conversation, we speak with Professor David Wilkinson — physicist and author of popular science books on Stephen Hawking to explore the question: can we ever fully understand time through science, or does it open up more mystery?
This Deep Dive AI podcast discusses my book The Physics of Time: D-Theory of Time & Temporal Mechanics, an insightful exploration into one of the most profound mysteries of existence: the nature of time. As part of the Science and Philosophy of Information series, this book presents a radical reinterpretation of time grounded in modern physics and digital philosophy. It questions whether time is a fundamental aspect of reality or an emergent property of consciousness and information processing. Drawing on quantum physics, cosmology, and consciousness studies, this work invites readers (and listeners) to reimagine time not as a linear, absolute entity, but as a dynamic, editable dimension intertwined with the fabric of reality itself. It challenges traditional views, blending scientific inquiry with metaphysical insights, aimed at both the curious mind and the philosophical seeker.
In this episode, we dive deep into The Physics of Time: D-Theory of Time & Temporal Mechanics by futurist-philosopher Alex M. Vikoulov. Explore the profound questions at the intersection of consciousness, quantum and digital physics, and the true nature of time. Is time fundamental or emergent? Can we travel through it? What is Digital Presentism?
The Physics of Time: D-Theory of Time & Temporal Mechanics by Alex M. Vikoulov is an insightful exploration into one of the most profound mysteries of existence: the nature of time. As part of the Science and Philosophy of Information series, this book presents a radical reinterpretation of time grounded in modern physics and digital philosophy. It questions whether time is a fundamental aspect of reality or an emergent property of consciousness and information processing.
The book introduces the D-Theory of Time, or Digital Presentism, which suggests that all moments exist as discrete, informational states, and that our perception of time’s flow is a mental construct. Vikoulov explores theoretical models of time travel, the feasibility of manipulating time, and the concept of the Temporal Singularity, a proposed point where temporal mechanics may reach a transformative threshold.
Researchers from the International Institute of Molecular and Cell Biology in Warsaw (IIMCB) have described a new mechanism that improves the efficiency of mRNA-based therapies. The research findings could facilitate the development of novel therapeutics against cancers and infectious diseases.
The scientific experiments were carried out at IIMCB, but important contributions also came from collaborators at the Faculty of Physics and Faculty of Biology of the University of Warsaw, the Medical University of Warsaw, and the Institute of Biochemistry and Biophysics of the Polish Academy of Sciences. The study by the Polish researchers has just been published in Nature.
“mRNA vaccines played a key role in controlling the spread of the pandemic. However, mRNA itself is an exceptionally unstable molecule. This does not affect the safety of the therapy but limits its effectiveness—for example, by shortening the duration of action. A particularly important role in mRNA stability is played by its so-called poly(A) tail. In our research, we examined these limitations,” says Prof. Andrzej Dziembowski from the Laboratory of RNA Biology—ERA Chairs Group at the International Institute of Molecular and Cell Biology in Warsaw, one of the lead authors of the study.
Here in this video today we will explore something that has been demanded by viewers of the channel for quite sometime, the Xeelee rings, one of the largest megastructures in fiction. We first have to take a look at the universe we are discussing about. So, The Xeelee Sequence is a series of science fiction novels and short stories by British author Stephen Baxter, exploring the grand scale of the universe from the Big Bang to its ultimate end. The series follows humanity’s evolution over billions of years, its conflicts with alien species, and the mysterious, hyper-advanced Xeelee, who are engaged in a cosmic war against the enigmatic dark matter entities known as the Photino Birds. The books blend hard science fiction with cosmic wonder, delving into themes of time travel, black hole physics, alternate universes, and the limits of human potential. Major works in the series include \.
New experiments on thallium decay have helped determine the Sun formed over 10–20 million years, improving stellar nucleosynthesis models. Have you ever wondered how long it took our Sun to form in the stellar nursery where it was born? An international team of scientists has just brought us clos
A pair of studies describing the findings also confirm the standard model of cosmology and offer compelling findings regarding the cosmological conundrum known as the Hubble Tension. The researchers also spotted light from several other sources, resulting in a virtual cosmic road map from the present to the beginning of time.
“We can see right back through cosmic history,” said Jo Dunkley, the Joseph Henry Professor of Physics and Astrophysical Sciences at Princeton University and the ACT analysis leader, in an announcement, “from our own Milky Way, out past distant galaxies hosting vast black holes, and huge galaxy clusters, all the way to that time of infancy.”
Time travel has long fascinated scientists and theorists, prompting questions about whether the future can send visitors into its own past and whether individuals could move forward in time in ways that bypass the normal flows of daily life. The general idea of time as a fourth dimension, comparable to spatial dimensions, gained traction when Hermann Minkowski famously stated that “space by itself, and time by itself, are doomed to fade away into mere shadows” (Minkowski, 1908, p. 75). This integrated view of spacetime underlies many physics-based theories of how a traveler might move along the temporal axis.
In relativity, closed timelike curves (CTCs) theoretically allow a path through spacetime that loops back to its origin in time. As Kip Thorne put it, “wormhole physics is at the very forefront of our understanding of the Universe” (Thorne, 1994, pp. 496–497). A wormhole with suitable geometry might permit travel from one point in time to another. However, such scenarios raise paradoxes. One common example is the “grandfather paradox,” which asks how a traveler could exist if they venture into the past and eliminate their own ancestor. David Deutsch offered one possible resolution by suggesting that “quantum mechanics may remove or soften the paradoxes conventionally associated with time travel” (Deutsch, 1991, p. 3198). His reasoning rests on the idea that quantum behavior might allow timelines to branch or otherwise circumvent contradictions.
Time travel has long been a captivating concept that has intrigued the human imagination. The idea of traversing through time, visiting the past or future, and altering events is a topic that has been widely explored in various forms of fiction and scientific speculation. This document aims to delve into the intricacies of time travel and its implications on the creation of alternate timelines. Through an in-depth analysis, we will explore the theories, controversies, and possibilities associated with this fascinating concept.
The Concept of Time
To understand time travel, it is crucial to comprehend the nature of time itself. Time is commonly perceived as a linear progression of events, moving from the past to the present and into the future. However, different theories propose alternative perspectives on time, such as the block universe theory, which suggests that time is a fixed four-dimensional block where past, present, and future coexist.
Scientists discovered that glass molecules shift unpredictably, reversing time at a microscopic level. This challenges our understanding of time and material science.
