This is exactly what physicists have done and the results are extraordinary.

This image of the CMB compared with simulated universes featuring lumps of varying sizes, allows us to conclude that we live in a flat universe; the lumps appear to be 1 degree in angular distance.

However, all the mass in the universe amounts to 0.3 as shown earlier, therefore both the visible matter and dark matter combined only amount to 30% of the mass required for a flat universe.

Therefore, we have to ask: where’s the other 70% coming from?

The odd thing is that it seems to be situated in empty space.

That is to say, there’s energy where there is nothing; most of the energy in the universe resides where there is nothing.

If you take a region of space and remove all the particles, the radiation and just everything, then it will still weigh something.

It turns out that when you combine quantum mechanics and relativity, empty space is a boiling – bubbling – brew of virtual particles and fields popping in and out of existence on a time scale far too small for us to observe them, and this is happening everywhere.

For example, less than 5% of the mass of a proton can be accounted for by its 3 quarks.

However, although we may not be able to observe them directly, we can measure their effects indirectly.

This is known as dark energy.
