As alternative theories go, it's not without its merits, but there's no evidence to support it...until now. He says he's found evidence for his ideas in the cosmic microwave background, the microwave radiation that permeates the universe and was thought to have formed 300,000 years after the Big Bang, providing a record of the universe at that far distant time. Penrose and his colleague Vahe Gurzadyan have discovered clear concentric circles within the data, which suggests regions of the radiation have much smaller temperature ranges than elsewhere.

So what does that mean? Penrose believes these circles are windows into the previous universe, spherical ripples left behind by the gravitational effects of colliding black holes in the previous universe. He also says these circles don't work well at all in the current inflationary model, which holds all temperature variations in the CMB should be truly random.

Here's where the fun begins. If the circles are really there and are really doing what Penrose says they're doing, then he's managed to overthrow the standard inflationary model. But there's a long way to go between where we are now and that point, assuming it ever happens.

The inflationary model has become the consensus for a good reason - it's the best explanation we've got for the universe we have now - and so cosmologists will examine any results that appear to disprove it very critically. There are also a couple key assumptions in Penrose's theory, particularly that all particles will lose their mass towards the end of the universe. Right now, we don't know whether that will actually happen - in particular, there's no proof that electrons ever decay.
