What It Means to Live in a Holographic Universe
When you look in the mirror, the image you see looks a lot like you—not exactly the same, because when you raise your right hand, your mirror-self raises its left. What’s more, the mirror image is merely an assemblage of reflected light, without a physical body behind it. Despite these differences, you can see an important connection between you and your reflection.

Is It Time to Accept That We're Alone in the Universe?
We have yet to discover any signs of aliens, a troubling observation that has led to much speculation. One possible solution to the Great Silence is that nobody's out there. It's a conclusion that sounds impossible to believe, but there may be something to it. Here's why we may be alone in the universe.

Can we test for parallel worlds?
A new theory suggests many worlds have existed, side-by-side, since the beginning of time. Parallel worlds are standard fare for sci-fi, but the idea originates from quantum physics where the seemingly bizarre notion of alternative universes is taken very seriously. Now an Australian team has taken the weirdness a step further. Their new theory, published last month in Physical Review X, is dubbed “Many interacting worlds”. It not only proposes that stable parallel worlds exist but...
