Ok so many of us have seen the Truman show. If not, go watch it. The way I explain the expansion of the universe is thus
Imagine we are inside a Truman like dome, its walls are the edge of the expansion of the universe. Truman’s island is surrounded by water to prevent Truman realising there is a wall. There is no real wall in the universe other than how far light has managed to reach.
So a light beam shoots out into the universe’s Truman dome across the waters on its little photon boat & hits the wall which is the furthest it can pull the matrix of the universe’s membrane blankets behind it, kind of like a stretchy mooring rope. So then the boat bounces back & decided to come home.
But as we said space has no real wall or fixed dome. So that boundary keeps expanding building layer upon layer from parts of the previous inner wall . As it has done for a very long time. & the wave that photon is riding back on has only just started to turn & come back. But the moveable boundary of the universe has had a head start. So now our little photon is trying to row back at the same speed that the expansion is happening, The photon’s speed is light speed. The same as the outward wave he made when trying to reach the wall. So as the boarder wall grows the photon on his little boat is tugging on his continually stretching mooring rope. & eventually he will be carried much further than we can ever see on a wave that never reaches home. It’s being sucked out like videos you see of the shoreline receding before a tsunami 🌊
The only thing we can see is what is between us & that wave. Stretched mooring ropes
& is also why we can’t see the expansion of the dome as its beyond that wave & the photon boats lights. But we can see everything in front of the wave appearing to be moving away from us
But the big worry is… that’s gonna be one hell of a wave if that tsunami comes back in. Total annihilation
But you still have plenty of time to enjoy a cup of chai.
This silly little story of a dome or wall is inspired by the CMB & the visualisation of the furthest reaches of the phenomenon. Because of it I have decided to call the edge of the Phenomenon or the most recent Phlash cycle Phractalation UnPhurling as the Truman Limit. It’s not a hard stop as the wall is being constantly built outwards. But it’s a reference to it’s current location at the moment (Phlash cycle) of observation or calculation + however long that light took toget to us
If we were to ever reach the Truman Limit, reality as we know it would never be the same.
