Ontology of Causal Dynamical Triangulation

[TheHeraclitus]

TL;DR Summary

Does CDT involve gravitons? How many dimensions? Presentism, Eternalism or Agnosticism about time?

Also, what does Sabine mean in this video by the sentence: (5:51 in the video)

It treats space and time differently which Einstein thought us not to do.

Thank you!

Also, what does Sabine mean in this video by the sentence:

It means that space and time are not treated on an equal footing. In other words, it's not manifestly relativistic covariant.

 

[TheHeraclitus]

It means that space and time are not treated on an equal footing. In other words, it's not manifestly relativistic covariant.

So it denies the reality of Spacetime?

 

[Demystifier]

So it denies the reality of Spacetime?

According to Sabine, yes.

 

[TheHeraclitus]

According to Sabine, yes.

Interesting, that would make sense since Wikipedia says CDT is related to Hořava gravity where space and time are treated differently too.
I am also a bit confused about the nature of space in CDT. Sabine says finite size of the triangles is only a mathematical aid.
Does this mean space is continuous or discrete in CDT?
