AI Thread Summary
Stephen Hawking's calculations suggest that the universe may be eternal and did not have a singular beginning, aligning with the standard model of cosmology. He, along with James Hartle and Neil Turok, explored cosmologies that utilize "Instantons" and a complex time coordinate to support this theory. The discussion emphasizes the complexity of these concepts, noting that they are not widely understood. The notion of eternity is framed as a continuous sequence of moments, where each moment has a preceding and a succeeding moment. This exploration of the universe's nature highlights the ongoing debate in cosmology regarding its origins and structure.

Calculation of Eternity.

Chères personnes.

Can you please forward informations and scientific references,
concerning Dr Stephen Hawking's calculations, that led him to
theorise and demonstrate, that the Universe never had a com-
mencement, and is Eternal.

Dieu vous bliss!

Last I heard, Dr. Hawking subscribed to the standard model of cosmology, where did you hear that he demonstrated that the universe had no beginning?
 
James Hartle, Niel Turok and Stephen Hawking worked on cosmologies that required no initial singular spacetime beginning, using math objects called "Instantons" and a complexified type of time coordinate. Check here for a quick introduction.

Formula for eternity

Eternity -
For every moment 'X' there will exist a moment 'X+1"
For every moment 'X' there did exist a moment 'X-1"
Any questions?

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
