Binding quantum matter and space-time, without romanticism

Understand

Understanding the emergence of a tangible 4-dimensional space-time from a quantum theory of gravity promises to be a tremendously difficult task.

• This article makes the case that this task may not have to be carried.
• Space-time as we know it may be fundamental to begin with.
• I recall the common arguments against this possibility and review a class of recently discovered models bypassing the most serious objection.
