QR2.4.1 Space is a Surface

In 1929 the astronomer Hubble found that all the galaxies were expanding away from us, implying a “big bang” about 14.5 billion years ago and finding its leftover radiation all around us today supports this. Physics concluded that this event began not only our universe but also our space and time. But if it all exploded “out”, why is the radiation from long ago still all around us today? And if the universe is expanding, what is it expanding into?

The current reply is that the big bang wasn’t really a bang – but what then was it? If in the beginning there was a singularity of all matter at a point, by current physics it  should have collapsed into a black hole from which nothing can emerge. So why wasn’t the universe stillborn? Something else was needed so according to inflation theory (Guth, 1998), an immense anti-gravity field then appeared from nowhere to expand the universe faster than light for 10-32 seconds. After solving the black hole problem, it then vanished to play no further part in the universe. The modern creation myth is that nothing made everything at a point that magically expanded faster than light to avoid a black hole until it stopped doing that for no reason and sedately evolved into the galaxies, stars and us. It isn’t a very convincing story.

In quantum realism, in the beginning there was a quantum reality we don’t understand and it created physical reality from itself. It emulates our space as the inner surface of a expanding hypersphere that like the surface of a balloon being blown up has no center or edge as it expands everywhere at once. The waves that move on its surface in any direction wrap around, so the early light went “out” then wrapped around to end up everywhere as cosmic background radiation. That our space is the inner surface of a big bubble not the outer surface of a big “bang”(Figure 2.11) answers questions like:

1. What is space expanding into? It is expanding into the surrounding quantum bulk.

2. Where is space expanding? Everywhere, as the bulk fills “gaps” that arise everywhere.

3. Where does new space come from? From the quantum bulk that contains the bubble.

4. Are we expanding too? No, existing matter isn’t affected as new space is added.
