Is God a Lazy Plumber?
13:27
Last Friday I had the privilege of going to a talk by CERN physicists Dr. Archana Sharma and Dr. Mick Storr. While the talk itself was unremarkable due to lack of technical depth (they tried to make it accessible to non-physics majors in the audience as well, but didn't, leaving no one satisfied).
But it wasn't a wasted day. Before the talk began, I happened to meet and talk to a fellow high-school physicist She and I started talking about a topic that fascinates me quite a bit - the outward acceleration of space.
Quick background: The universe is expanding quickly, we know this because of the Doppler Effect, which describes how light wave (any wave actually) 'elongates' when the source moves away from the point of observation. i.e. the wavelength increases, causing a red-shift. We see that with stars, they exhibit a red-shift more often than not, indicating that they are moving away from us, hence, space is moving away from us, expanding. In fact it's moving away from every point of observation. I like to look at stars as ink blots on a balloons skin, when you blow the balloon, the stars all move away from each other, hence moving away form all points of observation.
If this isn't fascinating enough, the stars are actually accelerating away from us. That's quite absurd, we know that for an object with mass to accelerate, a force must be applied to it. Newton's second law. For a force to be applied, energy must be expended. But where is this huge amount of energy coming from?
We call this mysterious energy 'dark energy'. We know nothing about it, and it fascinates me every-time I think about it.
Back to Friday. My friend pointed out a pretty interesting idea. She said that the stars would be being pulled outwards by the mass of adjacent universes. Super massive universes all pulling each other apart, growing rapidly with each others assistance.
The talk ended at 1:30pm, and I took the bus home. On the way I couldn't help but this about this concept. What if there were infinite neighboring multiverses, all pulling each other apart. Like fractals. Infinite universes pulling each other outwards, their gravity 'leaking'. The multiverses could exist on multiple levels, like fractals. So infinite multiverses won't be adjacent, they would be within each other.
But where does one universe end and the next begin? Watch out for the next post to find out.

Hi Daksh, really interesting theory! I have a question for you, do you think the multiverse theory holds for the big bang? Do all infinite universe start simultaneously?
