This new finding from the NANOGrav team is like adding another color – gravitational waves – to the picture of the early universe that is just starting to emerge, in large part thanks to the James Webb Space Telescope.
Everything else in the universe is either a particle or field. Dark energy behaves as neither, and it may be a property inherent to space itself.
China's Chang'e 4 mission to the moon has something else up its sleeve
If you conceive of the Universe as the full suite of matter and energy we know, and the early stages had it all compressed into a tiny region of space, then why didn't it collapse into a black hole?
Two degrees above absolute zero was never so hot.
A new analysis, undertaken jointly by the Bicep group and the Planck group, has confirmed that the Bicep signal [of gravitational waves from the Big Bang] was mostly, if not all, stardust, and that there is no convincing evidence of the gravitational waves. No evidence of inflation.
Pope Francis broke with Catholic tradition Monday by declaring that the theories of evolution and the Big Bang are real, and remarking that God is not “a magician with a magic wand.”
“When we read about Creation in Genesis, we run the risk of imagining God was a magician, with a magic wand able to do everything. But that is not so,” the pope said at the Pontifical Academy of Sciences, during a plenary meeting dedicated to evolving concepts of nature.
