Does time exist? The answer to this question may not be as obvious as it first seems.
Does time exist? The answer to this question may seem obvious: Of course it does! Just look at a calendar or a clock.
But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously.
How can that be, and what would it mean? Itll take a little while to explain, but dont worry: Even if time doesnt exist, our lives will go on as usual.
A crisis in physics
Physics is in crisis. For the past century or so, we have explained the universe with two wildly successful physical theories: general relativity and quantum mechanics.

(14,855 posts)If time isn't a fundamental feature of our universe, but rather emerges from other fundamental aspects of it, that doesn't mean that time doesn't exist.
That would be like saying molecules don't exist because they're composed of more fundamental chemical elements.

(129,199 posts)that "time" was a "4th dimension". Of course that has always been in debate. In "practical" terms - I could see that in my 3D (I think LC) plots back in the day, where each axis (X-Y-Z) represented some value (e.g., signal level, concentration, detector frequency change) and "time" would become a 4th via a series of "snapshots" of such a plot.
So it's basically something that "doesn't exist" on its own until, I suppose, we "'manually' make it exist". That's why it keeps "changing".
But...

(6,261 posts)The more I learn about quantum and what not, the more open I become to the notion that we're living in a simulation, or even that everybody but me is part of that simulation.
It seems that the more we think we understand the nature of reality, we zoom in and reveal another layer of complexity. Probably just as well. Keeps things interesting anyway.

(2,352 posts)So, time is an emergent property of space? Or gravity? Unfortunately it doesn't make much sense to me.
As an old person, I know my subjective time is running faster and faster.
