# The substratum visualization

Is physics *weird* at a fundamental level? Does a particle take two paths? Do worlds split? Is time an illusion?

We don’t think so. Physics is *not* weird in the substratum visualization. We develop this approach to Relativity and Quantum Mechanics, from the bottom up. We hope to leave you with strong visuals, intuition, and sanity.

A substratum (“fabric”) simply obeys the equations of GR or QM. We do not claim it being *the* correct “deeper reality.” There is no new theory, only visualizations and metaphors of standard theory.

Substratum *vs.* medium *vs.* interpretation. (video)

**Quantum mechanics**

**General relativity**

GR uses the *math* of curved surfaces. So we can visualize GR with a substratum that obeys the same math.

- What is curvature? In 2 dimensions, it’s a deformation within 2d,
*or*a buckling out into a third dimension. (video) - Curvature in 3 and 4 dimensions, Schwarzschild spacetime. (video)
- Slow light, bending light. (video)
- Space moves: spinning black hole, Kerr. (video)
- Wormholes, time machines. (video)
- Space expands: Big Bang, horizons, gravitational waves. (video)

Contentious topics:

- Can you fall into a black hole? (video)
- Can black holes form? (Coming later)

**Special relativity**

- Start with the three basic phenomena – length contraction, time dilation, clock desynchronization – and then discover that
*c*is measured to be constant, and that you cannot tell which frame is at absolute rest. (video)
