Loop quantum gravity. Loop quantum gravity (LQG) is a theory that attempts to describe the quantum properties of the universe and gravity. It is also a theory of quantum spacetime because, according to general relativity, gravity is a manifestation of the geometry of spacetime. LQG is an attempt to merge quantum mechanics and general relativity.
Eco Block, ARXX, Logixx are a few along with TriTex. Cost per block is around $12 and they are 5.33 sqft and various thickness depending on your needs. So a 35x43 house would need 234 blocks and about a ton (lift) of rebar, and require roughly 33 cubic yards of concrete using an 8  core thickness.
The Advantages. Our Redi-Rock blocks have 5.75 square feet of face surface area, which makes it the largest blocks available. Each block weighs between 1,500 and 2,500 pounds.Composed of 3,000 and 4,000 psi wet-cast concrete, these blocks are built to last a lifetime.And when it comes to holding back the earth,bigger is definitely better.
