I am reading a book by Carlo Rovelli, Seven Brief Lessons On Physics, and would like to check if I have understood something. Apologies if my question is badly phrased, feel free to edit where appropriate.
I am not a physicist, just an enthusiast.
It was this excerpt that made me think gravitational waves had something to do with time.
The heat of the black holes is like Rosetta Stone of physics, written in a combination of three languages-Quantum, Gravitational and Thermodynamic - still awaiting decipherment in order to reveal the true nature of time
And the following that made we wonder if they were to do with space as well? My understanding is that space and time are synonymous?
The heat of black holes is a quantum effect upon an object, the black hole, which is gravitational in nature...
It was the next line, following that inspired my question was this,
... It is the individual quanta of space, the elementary grains of space, the vibrating 'molecules' that heat the surface of black holes
Talking about the gravitational field being space-time
The gravitational field, as we saw in the first lesson, is space itself, in effect space-time
Text referred to in the 'First Lesson'
Einstein had been fascinated by this electromagnetic field and how it worked... soon came to understand that gravity, like electricity must be conveyed by a field as well... the gravitational field is not diffused through space; the gravitational field is that space itself
Question: Is space-time 'made of' gravitational waves? Is that field it's fundamental building block?
It seems to me from all of this that space-time is indeed
