What’s the Hottest Object in the Universe?

Thirty degrees might seem hot, when you’re sweating through your shirt in July—but on a cosmic scale it barely registers. The Sun itself is over 15 million degrees; and in a hottest-object contest, the Sun wouldn’t even rank. Scientists, in fact, have produced temperatures many times that, right here on Earth (in terms of kinetic energy in microscopic places). We reached out to a number of scientists for this week’s Giz Asks—astronomers and physicists—to find out what the hottest object in the universe actually is. Read More >>

Ultra-Cold Atoms Recreate the Expanding Universe in Tabletop Experiment

Eerie similarities unite vastly different scientific ideas in sometimes utterly surprising ways. One of these similarities may have allowed scientists to recreate the expanding universe—on a counter-top. Read More >>

Science Just Made the Most Massive, In-Depth Universe Simulation Ever

Ever wanted to see what our universe looked like just 12 million years after the Big Bang? Good luck—that kind of calculation would take your desktop computer more than 2,000 years. Luckily, researchers just published findings from the first ultra-realistic simulation of our universe's growth. And it covers 13 billion years. Read More >>

But if your bullet-resistant glass is sturdy enough, that speeding bullet will usually just end up lodged in layers of polycarbonate. That's what intrigues photographer Deborah Bay. Read More >>
