Anything before the Big Bang in a question:

Space & the Universe is expanding at an ever accelerating speed, this indicates once the Universe was smaller than it is now; up to a point form.

A state prior to the Big Bang necessarily needs to be a point form, having no dimension, besides space and time (those we know) cannot be there before the Big Bang. Prior to the Big Bang, it was a no dimensional singularity with gravity infinite. 

 

Immediately after the Big Bang and before a non-inflationary time classified as a Planck time i.e. 10^-43 seconds, it was not possible for any subatomic particles - e.g. nuclei, electrons or photons - to be existed then, it was too hot and dense for any particles to be stable, as all the known form of interactions must be united then as gravity - in absence of anything intractable; either through strong or weak nuclear interactions, or electromagnetic interaction, except gravitational interaction, - but then the first quarks formed.

 

Since we reside in three dimensional world; anything beyond that would be imperceptible to us, also anything in such extra dimensional state naturally would be a meaningless proposition to us.
