Time Travel?

Astronomers are looking back 13 billion years to the galaxies only 500million years after the big bang. Do you suppose that this is in effect time travel? It is a stream of light that you could follow back through time to an earlier year (of course if you followed this light you would end up in the middle of space - not a good thing really!)

Oh and they are also discussion the theory that stars used to be powered by dark matter or wimps (weakly interacting massive particles) there is more on that story here.
