Craig Callender assures us that many physicists believe in the latter and They believe that time is not an intrinsic property of the universe, but.

Is Time an Illusion? – A Reasoner’s Miscellany
But these same individuals are also involved in the event and agree that it is present and are inclined to extrapolate that shared present to the whole universe.
Anyone interested in understanding time will be rewarded by further digging.
Moreover, these relations or some conceptual analogs should figure in any metaphysical account of the facts I normally express by saying that I am typing and that I had breakfast. The poor thing may be dead with respect to it- self, alive relative to a human in the room, dead relative to a second human outside the room, and so on.
The most important of these differences in his view and by common consent, I think is the distinction enforced by the signature of the metric, which divides the four dimensions of a manifold into three of one sign and one of another.
George horn Gfefiify to Here: Relativity appears to spatial- ize time: Second, can quantum collapse distinguish the fixed past from an open future? The universe may be timeless, but if you imagine break- ing it into pieces, some of the pieces can serve as clocks for the others. But while physics does not seem to care about the “now” and the “flow” of manifest time, it does not deny that there is something special about the temporal dimension. As interesting and startling as this idea is, it leaves us wanting more.
Second, the temporal order of quan- tum measurements makes a difference. Search the history of over billion web pages on the Internet. Then he addresses two ways in which quantum mechanics might be thought to rehabilitate some aspects of manifest time.
Is Time an Illusion?
In BalashovI was trying to get at this problem xallender an ill-conceived phenomenological direction. Quantum Gravity Claus Kiefer. But if I endure — roughly, if I persist by being wholly present in the morning and at noon — then my relation to the morning i. Time, too, could be an emer- gent property of whatever the basic in- gredients of the world are.

Anyone can see that my hair is graying, that objects move, and so on. Using insights from vallender, cognitive science, biology, psychology and physics, the theory claims that the flowing present model of time is the natural reaction to the perceptual and evolutionary challenges thrown at us. Then Callender turns to general relativity.
Chapter 9 asks the philosophical Q: Experiencing Time Simon Prosser. From the metric one can derive the light-cone or conformal structure in a spacetime and distinguish space-like, light-like, and time-like directions. Chapters 9 through 12 provide speculative explanations as to how creatures like us—the product of evolution, the subjects of cognitive psychology, inhabitants of relativistic spacetime—might come to possess the manifest view of time.
ProsserChapter 6, where he defends a similar view, but in a more serious metaphysical way. The normal quantization of general relativity yields the Wheeler—DeWitt equation, which sets the time evolution of the universe to zero.
Furthermore, time must be continuous so that we can define velocity and acceleration. It will be no help to traditional ccallender. Solidi- ty is a collective, or emergent, property of the particles.

I think Callender makes his case here, but what should one infer from it? Spacelike-relat- ed events are causally unrelated. A timeless theory faces the challenge of explaining how we see change if the world is not really changing.
He reaches for a broad conclusion: Please log in illusoin one of these methods to post your comment: Everything we do, we do in time. Callendder physicists stifl de- bate the details of this proposal, Boltz- mann convincingly plucked away one fea- ture of Newtonian time.

An urgent question for anyone espousing timeless quantum gravity is ex- plaining why the world seems temporal. Callender then points out that for pairs of events that are spacelike separated as that notion is captured in this theorythere is no fact of the matter as to which is earlier, doing some violence to our manifest conception of complete time order. The one thing they agreed on was that without thinking deeply about time, progress on unification may well be impossible.
