@AgentGoldenSnitch : Yep I attended a lecture of Simon Singh in IITB and he told this story, but I had heard it first from this man here on a Ted talk(rather this very talk)

age of the universe is about 13.75 billion years, but due to the expansion of space we are observing objects that were originally much closer but are now considerably farther away than a static 13.75 billion light years distance. The observable universe is about 46.6 billion light years.(wiki- observable universe). Both of them are wrong butKatie is a very good singer, and she wrote good songs too. I wonder how seriously Simon takes his profession as he believed in common misconception.

@jakiedark Well obviously the first version was the original. The second version was just a joke by the singer.She didnt actually change it.

@AgentGoldenSnitch was that the GCSE science talks at the dominion theater? that was frickin awsum haha :P
-
I was at a lecture and Simon Singh told the exact same story. Lol.
-
18 people still think that we are 6 thousand light-years from the edge...

Yes celestial objects emit radio signals. Almost all of them do. All Stars and remnants of stars including Pulsars, Neutron Stars, Red Giants, black holes (Hawking Radiation), white dwarfs, brown dwarfs, Nova/Super nova. Not to mention Galaxies, Quasars and the big bang itself (Cosmic Microwave Background Radiation).
IF THEY DIDN'T, THERE WOULD BE NO RADIO ASTRONOMY!

@bradkey98765 That's why Simon Singh as careful to use the term 'Observable Universe'. The observable universe an certainly be described as having an edge, just like a horizon can be described as having an edge.
