This physicist's ideas of time will blow your mind.

Time feels real to people. But it doesn’t even exist, according to quantum physics. “There is no time variable in the fundamental equations that describe the world,” theoretical physicist Carlo Rovelli tells Quartz.

If you met him socially, Rovelli wouldn’t assault you with abstractions and math to prove this point. He’d “rather not ruin a party with physics,” he says. We don’t have to understand the mechanics of the universe to go about our daily lives. But it’s good to take a step back every once in a while.

Time is a fascinating topic because it touches our deepest emotions. Time opens up life and takes everything away. Wondering about time is wondering about the very sense of our life. This is [why] I have spent my life studying time,” Rovelli explains.

Rovelli’s new book, The Order of Time, published in April, is about our experience of time’s passage as humans, and the fact of its absence at minuscule and vast scales. He makes a compelling argument that chronology and continuity are just a story we tell ourselves in order to make sense of our existence.

Time, Rovelli contends, is merely a perspective, rather than a universal truth. It’s a point of view that humans share as a result of our biology and evolution, our place on Earth, and the planet’s place in the universe.

I listened to part of it and will get back to it. Fascinating insights and some very curious perspectives on the nature of time, its measurements, and variations.

This stuff randomly came up in a discussion at home yesterday-- where does everything go when time passes? Where is the future stored until it's ready?

Instinctively, we know time is simply an illusion, but we have no idea where to look for the reality behind the illusion. I doubt we'll find it in quantum mechanics where there are too many unanswered questions already, but we may find interesting things in dimensional shifts.

But, what do I know?

Side note, there was a post here about a month ago. It was about how the universe was gonna end.

Earth gets cold.
Sun goes dim.
Sun goes out.

and on and on..

Universe gets collapsed into many black holes

then, about 3 trillion years later, TIME STOPS.

About 4 trillion years later..... Now if time stopped at 3 trillion years, ........

When I think of the past moment... It lives in my mind... right now. When I think of the future, that thought lives in my mind... right now.. The past is now, the future is now...
The philosophy of it all fascinates me...

Anyone who observes what we call a day, from one sunrise to the next, or the phases of the moon,
knows what time is. There is such a thing as too much education and too much free time.

"Now the thing about time is that time isn't really real.
It's just your point of view, how does it feel for you?"
