Do We Live in a Purposeless Universe?
Just ninety years ago, we thought our galaxy was the extent of the Universe. Now we know hundreds of millions of galaxies exist in an ever-expanding Universe. Where does that leave us?
What's the Latest Development?
The last century of space exploration has changed our understanding of the Universe—and ourselves—more than all previous history. Most recently, the Large Hadron Collider has revealed the 'Higgs field', which apparently just happened to form throughout the space in our Universe. "It is only because all elementary particles interact with this field that they have the mass we observe today," says cosmologist Lawrence Krauss. And thanks to quantum mechanics, says Krauss, we can understand how our entire Universe was created from nothing.
What's the Big Idea?
If gravity is also governed by quantum mechanics, Heisenberg's uncertainty principle implies that entire Universes might appear and disappear in what is otherwise entirely empty space. In other words, we may need to reevaluate what we understand to be 'something' and 'nothing'. And so the famous question, 'Why is there something rather than nothing?' is revolutionized. "Asking why we live in a universe of something rather than nothing may be no more meaningful than asking why some flowers are red and others blue," says Krauss, who prefers an impossibly complex universe to hiding behind fairy tales that justify our existence.

A study on flies may hold the key to future addiction treatments.
- A new study suggests that drinking alcohol can affect how memories are stored away as good or bad.
- This may have drastic implications for how addiction is caused and how people recall intoxication.
- The findings may one day lead to a new form of treatment for those suffering from addiction.
There is no doubt that the historical Jesus, the man who was executed by the Roman State in the first century CE, was a brown-skinned, Middle Eastern Jew.
I grew up in a Christian home, where a photo of Jesus hung on my bedroom wall. I still have it. It is schmaltzy and rather tacky in that 1970s kind of way, but as a little girl I loved it. In this picture, Jesus looks kind and gentle, he gazes down at me lovingly. He is also light-haired, blue-eyed, and very white.
A new study shows choosing to be active is a lot of work for our brains. Here are some ways to make it easier.
There's no shortage of science suggesting that exercise is good for your mental as well as your physical health — and yet for many of us, incorporating exercise into our daily routines remains a struggle. A new study, published in the journal Neuropsychologia, asks why. Shouldn't it be easier to take on a habit that is so good for us?
