Up until now, we’ve considered time as fundamental in our existence. Yet, recent findings literally turn this idea on its head.
...
Along the way, I discussed a popular idea some theoretical physicists believe — that time is an illusion. And, they have some pretty strong arguments.

On the surface, the existence of time appears obvious. After all, humans divided it into seconds, minutes, hours, days, weeks, months, and years. Yet, all of that is just various measurements of the planet’s rotation around the Sun. For instance, day on Jupiter is a different length than a day on Earth.
Time is constant, but it’s also relative. Our ability to measure it depends entirely on our location and access to the outside world. Check out this article about what happened to a guy’s sense of time after staying in a cave without clocks or sunlight for 40 days.

Rovelli argues that time is an illusion. In part two of his book, he proposes that instead of assuming particles and fields are the components of the world, perhaps the actual constituents driving reality are the events themselves.
...
[Rovelli] We assume particles collide because space and time feel eternal and unmoving, allowing for events to occur. Yet, is it possible we have it backward? Perhaps it is events that create space and time.
...
A growing number of physicists, working in different areas of the discipline with different approaches, are increasingly converging on a profound idea: space — and perhaps even time — is not fundamental. Instead, space and time may be emergent: they could arise from the structure and behavior of more essential components of nature.

Consider this, let’s pretend the physicists are correct, that spacetime emerges from an accumulation of theoretical particles known as infatons. The result of which is what we experience as a seeming smooth reality. Then isn’t that sorta like Rovelli’s concept — that an accumulation of moments create what we experience as time? Which is still technically emergent, just in a different way than loop gravity theory
