When we understand what to do with time in quantum gravity we'll have it done.

There are a number of other approaches to quantum gravity.

This, however, is difficult to determine in the case of quantum gravity, for two reasons.

It can also be viewed as a different approach to the problem of quantum gravity.

"Most of what we know about quantum gravity, for instance, we've learned in the last eight standard months."

Quantum gravity can be treated as an effective field theory.

Quantum gravity, as we will see, cannot make that assumption in the first place.

This conclusion could change when quantum gravity is taken into account.

Some progress has been made in various approaches to quantum gravity.

We do not yet know the exact form the correct theory of quantum gravity will take.

Nevertheless, the ground state energy has many implications, particularly in quantum gravity.

As a result, the effects of quantum gravity are extremely weak.

There ought to be a theory of quantum gravity - but nobody has been able to find one.

That demands a complete theory of quantum gravity, which nobody has.

A theory of quantum gravity is needed in order to reconcile these differences.

The causal sets programme is an approach to quantum gravity.

This would make loop quantum gravity a candidate theory of everything.

Third, there is the Problem of Time in quantum gravity.

Proposals towards a theory of quantum gravity do away with this picture.

It is being used for research into gravitational waves and quantum gravity.

His research interests include general relativity, quantum gravity, and time travel.

This development raised new hopes for the canonical quantum gravity programme.

His major research interests are large extra dimensions, quantum gravity, and the very early universe.

They are particularly relevant in research on unified theories such as quantum gravity.

There is a lack of experimental evidence that relates to quantum gravity.
