The mysteries of the universe are as vast and wide as existence itself. Throughout history, mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker's Guide to the Galaxy, "I think the problem, to be quite honest with you, is that you've never actually known what the question is."
True, we have yet to come up with the answers to life, the universe, and everything — but oh do we have questions! Solving these mysteries may help to explain not only the creation of the universe, but also how it works, why it works, and possibly how it will end.
1. The Higgs boson
The Higgs boson is a hypothetical particle whose accompanying field is believed to be accountable for giving all other fundamental particles their mass. It is also the only elementary particle theorized in the Standard Model — the closest thing modern physics has to a "theory of everything" — that has not yet been actually observed through experiments. Why the difficulty proving this particular particle's existence? The Higgs boson has such a rapid decay that its appearance in the world is ineffably brief. Instead, physicists look for evidence of the particle's decay itself through experimentation.
The European Organization for Nuclear Research (CERN) has been working to find the elusive particle via experiments at the Large Hadron Collider — the world's largest and most ambitious particle accelerator. By accelerating particles at the LHC to near the speed of light and then smashing them into each other, scientists have recently been able to estimate that they will likely find the signal for the particle somewhere around the mass of 115 to 130 GeV. Now that we know where to look, we're likely to find out sooner than later whether the Higgs boson exists or not — and for physicists around the world, that'll be exciting news either way.
