Starting with Tetrahedrons, you can create a MerKaBa like so (using a template from here):
You then start putting them together (you'll need 8 in total):
Eventually you'll get to the full 64 grid star tetrahedron. Some people like Nassim Haramein think this holds the secret to the vacuum of space, solving the problem of "dark matter" and "dark energy" along with why atoms don't fly apart or collapse in on themselves.
He's got some really interesting theories. I listened to hours of his lectures on theoretical physics and how it relates to sacred geometry, the flower of life, the tetragrammaton (name of God), and what was inside the ark of the covenant (potentially a "black star" black hole device which could create unlimited energy and control gravity). All fascinating stuff, though surely pretty "out there" as well.
I don't know if any of this is "real" in that in matters to our conscious experience of reality... but I'm certainly curious. Either way, my son Devon had fun helping me create and learn about these shapes. We were inspired by this three part series I found on YouTube: part 1, part 2, and part 3.
