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.
Welteislehre, a.k.a. the World Ice Theory or Glacial Cosmogony – ice is proposed to be the basic substance of all cosmic processes and ice moons, ice planets and the "global ether" (also made of ice) had determined the entire development of the universe.
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 ...
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.
The word theory in "the theory of evolution" does not imply scientific doubt regarding its validity; the concepts of theory and hypothesis have specific meanings in a scientific context. While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains an observable phenomenon in
Scientists argue that primordial black holes should have caused the Higgs field to collapse, preventing the universe's formation, challenging current models.
The A-series identifies positions in time as past, present, or future, and thus assumes that the "present" has some objective reality, as in both presentism and the growing block universe. [8] The B-series defines a given event as earlier or later than another event, but does not assume an objective present, as in four-dimensionalism.
Scientists say they've discovered a new galaxy that's so dark and compact, it's basically invisible. But it's actually been here the whole time. Whoa, Scientists Found the Universe's Invisible Galaxy
