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.
Julian Barbour (/ ˈ b ɑːr b ər /; born 1937) is a British physicist with research interests in quantum gravity and the history of science.. Since receiving his PhD degree on the foundations of Albert Einstein's general theory of relativity at the University of Cologne in 1968, Barbour has supported himself and his family without an academic position, working part-time as a translator ...
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 ...
The scientists therefore suggest that the Drake equation should be better defined so it takes account of how many planets have continents and oceans and long-lasting plate tectonics.
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
Scientists argue that primordial black holes should have caused the Higgs field to collapse, preventing the universe's formation, challenging current models.
The research suggests matter is not as “clumpy” as would be expected based on the current best model of the universe. According to the scientists, this adds to a body of evidence that there ...
