https://theconversation.com/bizarre-dark-fluid-with-negative-mass-could-dominate-the-universe-what-my-research-suggests-107922   Sound familiar? They even use the analogy of bubbles because they can be modeled as having negative mass. This "dark fluid" sure sounds a lot like Leo's description of the Universe as a sponge... It's striking how this brand new theory at the cutting edge of physics and cosmology gets a little closer to the infinite void of Consciousness we know it to be... Anyways, I hope you find the chance to read it, it's fascinating. I think it's a lot more relevant than you might expect.
