“We may be at a point where we need a radical departure from the standard [story of our universe], one that may even require us to change how we think of the elemental components of the universe, possibly even the nature of space & time.” nytimes.com/2023/09/02/opinion… #space #science #history #news

in reply to Sheril Kirshenbaum • • •Yes. Big Bang is Illusion.
The reality is probably like Game of Life at Planck Scale in 3 dimensions.
Infinite Universe. Always existed.
It will be a difficult model to debug.
No way to measure. No way to test.
A pure Philosophical mental exercise.
But, that is my mental model to conceptualize with.
Whatever model can work, it must be logical.
Otherwise, Heisenberg will show up.

in reply to Sheril Kirshenbaum • • •I've always suspected that gravity is due to "particles" (gravitons ?) incoming from the circumference of a sphere (which is the "universe"), toward the center (big bang origin).
So gravity is not actually an attractive force, but one caused by the motion of these particles toward the center, their imparting of energy to what they travel through.
And so I expect that the gravitational constant increases as you get closer to the origin.
Thus, galaxies would form near the origin more quickly than at the periphery.
But I'm just a software engineer...

in reply to Sheril Kirshenbaum • • •What I love about physics is there will always be another level of mystery to solve. And each time it flips our preconceptions like a judo master in zero gravity.
From "We are the center of everything" to "Oh, that smudge in the night sky is a whole other galaxy" to "Um, hey guys, the universe isn't slowing down but actually expanding faster," we learn the most when we get a moment of "Wut?" and start working on our next quantum leap of knowledge. And I, for one, am enjoying the ride.

Please use a trustworthy source as a news organisation that refuses to comply with EU law has lost all credibility in my book.
