Thanks to John Merryman for suggesting the topic of this post. Earlier this month, a team of astronomers led by Roger G. Clowes at the University of Central Lancashire reported the discovery of the largest structure seen in the universe, a clump of...

Hanny's Voorwerp, and Other Year-End Goodies
By WILLIAM OREM
The new year is upon us: first step—according to the Gregorian calendar, anyway—of our next long loop around the sun. Time to look back over some of the most interesting Foundational stories from the previous trip.

Here, in no order, are...




NEW PODCAST EPISODES
Time travel is simulated in the lab; Alan Guth on the doubts clouding the BICEP2 result; how the Higgs should have destroyed the universe already; & could entropy explain why nature obeys quantum rules?
Andrei Linde and Joao Magueijo on the BICEP2 discovery of primordial gravitational waves; using thermodynamics to explain the origin of gravity; & is quantum entanglement the fundamental glue that binds reality together?
Max Tegmark proposes that consciousness may be another state of matter in his talk at the 4th FQXi International Conference.

Ultimate Reality
Alternative Models of Reality
By ZEEYA MERALI
If you have an unconventional, alternative model of reality, then this is the place to discuss it. (This is for contributors who have preliminary ideas and would like feedback, but do not have an academic paper or arXiv preprint and have not given a...

Ultimate Reality
Tegmark's Mathematical Universe
By ANTHONY AGUIRRE
While he would be too modest to toot his own horn, there's nothing stopping me from pointing out that 'mad Max' has recently put out a very interesting paper on whether all possible formal systems (and the 'physical' universes that some subset of...

High Energy Physics
Pieces of E8
By A. GARRETT LISI
There are very few moments in theoretical physics that qualify as... thrilling -- moments that send shivers of excitement down the spine and make the brain tingle. It's such an abstract pursuit, you wouldn't think the effects would be so visceral....
