Did the Higgs boson discovery reveal that the universe is unnatural?

We discovered the elusive Higgs boson last year, but it wasn't exactly what we expected. According to some physicists, that means the universe itself isn't quite what we thought either.

Over on the Simons Foundation website, Natalie Wolchover has a great introduction to this bizarre idea:

On an overcast afternoon in late April, physics professors and students crowded into a wood-paneled lecture hall at Columbia University for a talk by Nima Arkani-Hamed, a high-profile theorist visiting from the Institute for Advanced Study in nearby Princeton, N.J. With his dark, shoulder-length hair shoved behind his ears, Arkani-Hamed laid out the dual, seemingly contradictory implications of recent experimental results at the Large Hadron Collider in Europe.

“The universe is inevitable,” he declared. “The universe is impossible.”

The spectacular discovery of the Higgs boson in July 2012 confirmed a nearly 50-year-old theory of how elementary particles acquire mass, which enables them to form big structures such as galaxies and humans. “The fact that it was seen more or less where we expected to find it is a triumph for experiment, it’s a triumph for theory, and it’s an indication that physics works,” Arkani-Hamed told the crowd.

However, in order for the Higgs boson to make sense with the mass (or equivalent energy) it was determined to have, the LHC needed to find a swarm of other particles, too. None turned up.

With the discovery of only one particle, the LHC experiments deepened a profound problem in physics that had been brewing for decades. Modern equations seem to capture reality with breathtaking accuracy, correctly predicting the values of many constants of nature and the existence of particles like the Higgs. Yet a few constants — including the mass of the Higgs boson — are exponentially different from what these trusted laws indicate they should be, in ways that would rule out any chance of life, unless the universe is shaped by inexplicable fine-tunings and cancellations.

In peril is the notion of “naturalness,” Albert Einstein’s dream that the laws of nature are sublimely beautiful, inevitable and self-contained. Without it, physicists face the harsh prospect that those laws are just an arbitrary, messy outcome of random fluctuations in the fabric of space and time.

DISCUSSION

I'm not sure why so many people in the article seemed unhappy with the multiverse theory. To me it actually makes a good deal of sense, and would go a long way towards proving and disproving various other hypothesis about the origin of the universe and life itself. I also find it funny how many people were saying that if the universe is not "natural" then so much else collapses in physics. Why can't we just accept that there are some things we cannot understand now, that one day human being will understand? I understand the desire to understand everything right away, but I find it odd that, for theories that really have only been developed within the last 200 years, a speck of time in humanities lifespan, that we feel we need to and can understand everything right away. Maybe this is a good time to step back and rethink some things, but the frustrated hopelessness just seems very odd to me.
