Cosmos may show echoes of events before Big Bang

The variation in the background
shifts sharply within the rings

Evidence of events that happened before the Big Bang can be seen in the glow of microwave radiation that fills the Universe, scientists have asserted.

Renowned cosmologist Roger Penrose said that analysis of this cosmic microwave background showed echoes of previous Big Bang-like events.

The events appear as "rings" around galaxy clusters in which the variation in the background is unusually low.

The unpublished research has been http://arxiv.org/abs/1011.3706">posted on the Arxiv website.

1. It's the undulation of our brane before brane two collided with ours.

2. I'm a loop quantum gravity guy

so you're talking nonsense to me.

4. At least my nonsense doesn't equal zero or infinity.

6. nice shot.

but I can derive space and time from first principles.

3. does this mean a particular universe goes though periods of "live" and "dead" states

repeatedly?

fascinating stuff

5. Penrose does a FAIL with his assumption that black homes destroy info and entropy.

One of the theoretical reasons behind the holographic principle is that black holes do not destroy entropy and preserve information in garbled form that is released as the black hole evaporates.
