Why It's IMPOSSIBLE for Time to Have a Beginning | Brian Greene

What came before the Big Bang? Can time itself have a starting point — or does that question even make sense? In this mind-bending exploration, world-renowned theoretical physicist Brian Greene challenges one of the deepest assumptions in all of science: that time had a beginning.
Drawing on the frameworks of general relativity, quantum mechanics, string theory, and cosmology, Greene unpacks why the very concept of a "beginning of time" may be not just unknown — but fundamentally impossible. If time is woven into the fabric of spacetime itself, then asking what existed before time is like asking what lies south of the South Pole.
Join one of the greatest science communicators of our era as he takes you to the very edge of human understanding — where physics meets philosophy, and certainty gives way to profound wonder.
In this video:
Why the Big Bang may not be the true "beginning"
How Einstein's relativity redefines our understanding of time
The role of quantum gravity in erasing the concept of a cosmic starting point
What "no boundary" proposals in cosmology reveal about the origin of the universe
Why asking before time may be a meaningless question
Brian Greene is a professor of physics and mathematics at Columbia University, director of its Center for Theoretical Physics, and co-founder of the World Science Festival. His books — including The Elegant Universe, The Fabric of the Cosmos, and Until the End of Time — were all top 10 New York Times bestsellers, and he has hosted Emmy and Peabody Award–winning NOVA miniseries based on his work.

Especially how “fast” this actually is, is what we are struggling with.
Things change is all we know. Some “reactions” are reversible (like no time has passed) others are not. I believe people are still dealing with it.

Whatever the answer, there is a huge assumption in the model: the period of assumed inflation.
Assumptions have a record of sticky ends in all theories. They are inserted to make a theory that is not working, work.
Time dilation doesn't existence for pure mechanical mean...
