What does it mean for time to ‘pass’ and why does it feel like it doesn’t?
It doesn't feel as though time is passing. Where's time passing? Time remains the central concept in physics that is least understood. There's lots of debates in the biology aren't there about whether God exists outside of time. I think that's extremely interesting.
Professor Simon Saunders, Emeritus Fellow at Merton College, Oxford, is one of the most celebrated philosophers of physics alive, working on what time actually is.
I find it almost insane that all of the minuti of our present existence with all its craziness and insanity built in from the beginning of the world. No, I cannot believe it. It is not necessary.
On this channel, I, Kirchhay Mungle, interview researchers regarding their theories of reality with rigor and technical depth. Today, we go deep into the philosophy of time and what any of this has to do with the many worlds interpretation. We go over the professor's boldest claim that the violation of Bell's inequalities is not evidence against locality, it's evidence for the many worlds. We even touch on consciousness.
I am just in my Everetsian branch, you are in your Everetchian branch. We can coherently treat ourselves as a sort of extended observer.
Professor, what is time?
Yeah. Yes, the easy questions first. Richard Feynman said something about time. He said this. He said time is how long you have to wait. And you can't really say anything more than that. uh without getting into trouble. And you know, it it goes back to I forget the name of the philosopher now. That says, you know, time if I have to if I if I nobody asks me what it is, I know perfectly well but as soon as I am asked, then I become deeply puzzled and so forth. So yeah, I mean time I think probably remains the central concept in physics. that is least understood. I think that's probably right to say. So at some fairly fundamental level we I think do not altogether understand time. But we have very adequate representations of it in physics.
And we know how to deal with it in our ordinary lives. But it is extraordinary. I mean look, but uh think of it in terms of just your life. Whatever you've lived perhaps only twenty, twenty-five years, heavens. Um, long enough. Uh there are many, many hours packed into those years. Consider yourself in any one of those hours. There's time to think and comment and reflect and you know. uh look around and so forth. This is you being you. This is you being a person living in an ordinary way over a period of say an hour. But then there are thousands of such persons in the On that basis. Because there's been thousands of hours where you have lived through those hours. So there's thousands of uh call them larger than moments.
I don't want to make it just something instantaneous. Uh there are thousands of Times of your life. Persons, as it were. Considering themselves at the time to be all that they are, that there's nothing more to them. As I speak now I'm not considering that there's more to me in the future. Ah, so I'm perfectly adequate as a person with my past, but then there are thousands of persons with my past. Going back in time. Uh I'm one of those thousands. And of course if we make it not an hour but a minute, we make it not a minute but a second. If we really compress it, you can have as large a number as you like of previous moments. So What is the status of all of those moments? I mean, how do we kind of deal with that reality, that multiplicity of realities?
Because each seems like a reality. You know, you ask me what is real, I can't do better than just point to stuff around us and say, Well look, you know, this is what's real. It's Johnson kicking the stone. So they're all realities and they all somehow exist. Well, they don't all exist at the same time. They exist with a sequential structure, and more than that there's a causal structure, and we build and build and build until we've got a quite an elaborate understanding of that multiplicity as something fairly integrated. And yet there remains something really problematic about it all. It seems That we ought to take all of those momentary me's as equally real.
