The growing block universe, or the growing block view, is a theory of time arguing that the past and present both exist, and the future as yet does not. The present is an objective property, to be compared with a moving spotlight. By the passage of time more of the world comes into being; therefore, the block universe is said to be growing.
According to Carter, the universe is composed of what he calls "circlons", ring-like structures like "atomic LEGO blocks, interlocking rings that snap together to form all the elements". [3] He proposes that instead of the Big Bang theory, the universe began when two circlons combined and mated, subdividing to make up all the matter in the ...
Luminiferous aether theory; Static Universe theory [14] Steady state theory, a model developed by Hermann Bondi, Thomas Gold, and Fred Hoyle whereby the expanding universe was in a steady state, and had no beginning. It was a competitor of the Big Bang model until evidence supporting the Big Bang and falsifying the steady state was found.
Some philosophers appeal to a specific theory that is "timeless" in a more radical sense than the rest of physics, the theory of quantum gravity. This theory is used, for instance, in Julian Barbour's theory of timelessness. [20] On the other hand, George Ellis argues that time is absent in cosmological theories because of the details they ...
Time Reborn: From the Crisis in Physics to the Future of the Universe is a 2013 book by the American theoretical physicist Lee Smolin. Smolin argues for what he calls a revolutionary view that time is real, in contrast to existing scientific orthodoxy which holds that time is merely a "stubbornly persistent illusion" ( Einstein 's words). [ 1 ]
The universe is permeated by a field known as the Higgs field, which gives everything its mass. But the Higgs field isn’t entirely stable, and if it were to “bubble,” it would change reality ...
For a century, scientists have thought that the universe was expanding in all directions. To make that assumption work, astronomers have used the concept of dark energy.
Ray Jayawardhana, Canada Research Chair in observational astrophysics at the University of Toronto, wrote for The Globe and Mail that Krauss "delivers a spirited, fast-paced romp through modern cosmology and its strong underpinnings in astronomical observations and particle physics theory" and that he "makes a persuasive case that the ultimate ...
