Astro2 presents "Speed in the Universe" by John Fl

The Next Astro2 Talk will be given by John Flannery, from South Dublin Astronomy Society, who'll be talking on "Speed in the Universe"

John will discuss how the many motions of the Earth about it's axis, about the sun, around the galaxy and through the Universe have been fundamental in destroying the one-cherished notions that the Earth was the centre piece of the Universe and relegating us to just one more planet orbiting just one more star.

The talk will begin at 7:30pm next Tuesday, November 21st, at 7:30pm in JH4

It will be preceded by the next debate/discussion in the series, "The Physics of Consciousness and the Mind", which will be introduced and chaired by Sarah Kennelly. That'll start at 6:00pm

Both of these events will take place in Lecture 4, which is on the First Floor of the John Hume Building, on the North Campus of NUI Maynooth.

The talks are open to all, and will be followed by a pringles-and-wine reception, and observing using the University Observatory, if weather permits

Just some food for thought...

Over the past few decades astronomers have found that the redshifts of galaxies are not evenly distributed but are 'quantized', i.e., they tend to fall into distinct groups. This means that the distances to the galaxies also fall into groups, with each group of galaxies forming a conceptual spherical shell. The shells turn out to be about a million light-years apart.

It is remarkable that the shells are all concentric and all centered on our home galaxy, the Milky Way. If they weren't, we would not see groups of redshifts. These groups would only be distinct from each other if our viewing location were less than a million light years (a trivial distance on the scale of the universe) from the centre.
