Galaxies in the Mist

Galaxies in the Mist

[warning Will Robinson: the voices in my head that used to help write Slacker Astronomy are forcing me to write in the genre of a sensationalized nature special] One of the most elusive creatures speculated to lurk within the sky are the mysterious very high-redshift Lyman alpha emission galaxies. These systems, without the metal found in their more common and larger low-redshift cousins, are rich in hydrogen and slow in producing stars. Scientists had long speculated these systems had to exist, but despite 30 years of searching beyond the Lyman Alpha Forest, none of these systems had ever before been found. Now, astronomers using the Very Large Telescope in Chile bring us word of a serendipitous discovery of 27 of these elusive systems. They were found quite by...

1 Void a 2nd Universe Makes?

Ok, so New Scientist is just not making my brain happy this week. I decided to forage around their website  to see what was there (one of their editors, Maggie McKee, is a friendly soul I worked with at Astronomy and I wanted to see what’s she’s up to now a days). While Maggie has been writing a whole series of nice, interesting, valid pieces, I found another cosmology based story that just hurt. Some background… Many cosmologists believe our universe is one of many parallel or branching universes.  These universe’s, if these theories are right, are boiling and seething side-by-side, and (if these theories are correct) these parallel multiverses may periodically merge like two soap bubbles meeting in the wind. It may, if these...

I see you, now you must die

The title is a summary of how a New Scientist article seems to interpret the fate of the universe. Basically, the article states that because we view the universe, we may be causing the collapse of wave functions that would otherwise be happily balanced between not alive and not dead (the Schrondinger’s litter of supernovae, dark energy, and many other phenomenas). Think of it this way, has a supernovae really gone off if no one was there to observe it, or alternatively if no one observed its light echo, the planets formed out of its waste products, or the nebula created when its shock wave interacts with the interstellar media. If no one ever observed any of these things, would the supernova exist? Thought questions like this have pretty much always been...
