The Planck length is an extremely small distance constructed from physical constants. Many misconceptions generally overstate its physical significance, stating that it’s the inherent pixel size of the universe. The Planck length does have physical significance, and I’ll discuss what it is and what...
Robert Lawrence Kuhn is the creator, writer and host of "Closer to Truth," a public television series and online resource that features the world's leading thinkers exploring humanity's deepest questions. Kuhn is co-editor, with John Leslie, of "The Mystery of Existence: Why Is There Anythin...
What is faster than Planck time? What is Planck time used for? What happens to time at the Planck length? How fast do surface waves travel? What is the significance of the Planck time? How does simultaneity figure in time dilation? How does time slow down at the speed of light? How ...
What we are going to discuss next is whether the sequence of states {… S-2, S-1, S0, S+1, S+2,…} is a physical reality or, on the contrary, is a purely mathematical construction, such that the concept of past, present and future is exclusively a consequence of the perception o...
But I didn't realize the significance of those questions until I made a model for how light moves through the 9-dimensions of physical space. In my model, light is being pulled from point to point by a force. It travels from one point to the next in the same amount of time, even ...
This is further supported by our result on the significance of color elaboration (i.e., rare colors departing from the average brown/grey), which was the variable with the strongest positive association to attractiveness among all those considered (Fig. 2). Further studies are needed to ...
What is the displacement of space-time? Where does the special theory of relativity apply? Is there absolute simultaneity? What are the consequences of special relativity? What is Planck time? What is the significance of the Planck time? Does space-time include time? What are the postulates of...
Of Particular Significance What’s a Proton, Anyway?The Large Hadron Collider is mainly a machine for smashing protons into each other. But what’s a proton? First and foremost, it’s a mess. A total mess. As ugly and chaotic as a hydrogen atom is elegant and simple. Ok, then, what...
through epigenetic modifications, e.g., DNA methylation. Mutations can likewise prevent protein expression and particle formation, yet these elements may affect host cell functions [51]. The significance of these TEs has been a fertile topic for speculation among biologists. Is it “junk DNA” [...
The Significance of Energy Quanta The discovery of energy quanta was a major breakthrough in physics, as it revealed that matter and energy are not separate entities, but different aspects of the same reality. It also showed that physical phenomena at the subatomic level cannot be explained by ...
