    Challenges→The canonical approach to quantum gravity is arguably similar to string theory in its reliance on classical background spacetime

    The Wheeler-DeWitt equation, central to canonical quantum gravity, contains no explicit time parameter, suggesting background temporal structure is eliminated rather than presupposed.

    Key Terms

    Background temporal structure(as used in philosophy of physics and metaphysics)
    The basic framework of time that we normally assume exists independently in the universe—like time being a container that events happen inside of.
    Canonical quantum gravity(as used in theoretical physics)
    An approach to combining quantum mechanics and gravity that treats space and time as separate things, building on Einstein's original description of gravity.
    Eliminated (in this context)(as used in philosophical analysis)
    Removed or shown to be unnecessary, rather than being something that must exist for the theory to work.
    Presupposed(describing what hinges require of any reasoning process)
    Something that must already be assumed or taken for granted in order for something else to make sense or work.

    Wheeler-DeWitt equation(as used in quantum gravity)
    A mathematical equation in physics that tries to combine quantum mechanics (the rules for tiny things) with general relativity (the rules for gravity and space-time). It's named after physicists John Wheeler and Bryce DeWitt who developed it.
