The Loh Down On Science

Big Gulp

Do black holes suck?  Why yes, they do!

This is Sandra Tsing Loh with the Loh Down on Science

And on large quasar groups.

What? Let's back up. Out in space, quasars form wherever massive black holes are sucking in gas. That gas-gulping releases huge amounts of energy in the form of light. Astronomers call those light shows "quasars." And they're some of the brightest things in the universe.

They also tend to cluster together--hence the clever name "large quasar group." Astronomers have just found the biggest LQG to date.

Just how big is it? Traveling at the speed of light, it would take four-billion years to cross from one end to the other. Or, imagine lining up thirty-thousand Milky Way galaxies, end to end: this LQG would still be bigger!

The finding is forcing scientists to rethink current theories about the scale of the universe.
Instead of Big Bang, think OMG Redonkulously HUGE Bang!  If that helps you.
