Astronomers have created a 3D map of a cosmic structure so gigantic that it's almost impossible to even comprehend. The "South Pole Wall" is a flabbergasting 1.4 billion light years across and contains hundreds of thousands of galaxies, Live Science reports.

A new study published in Physical Review Letters presents evidence for the creation of matter and antimatter from energy, specifically light particles (photons). In doing so, it offers a splendidly concrete example of the world's most famous equation: E=mc2. The equation, derived by Einstein, dictates how energy (E) is equivalent to mass (m) times the speed of light (c) squared.

A subatomic particle has been found to switch between matter and antimatter, according to Oxford physicists analyzing data from the Large Hadron Collider. It turns out that an unfathomably tiny weight difference between two particles could have saved the universe from annihilation soon after it...

Matter is what makes up the universe, but what makes up matter? This question has long been tricky for those who think about it - especially for the physicists. Reflecting recent trends in physics, my colleague Jeffrey Eischen and I have described an updated way to think about matter.
