Stardust in the recipe for celestial bodies |  Life

If you want to make a comet, asteroid, planet, star, or many other bodies, the recipe is the same. There is just one ingredient: the cosmic clouds of gas and dust. The procedure is the same; one just gathers some of the material into a lump. What you end up with is entirely determined by … Read more

Physicists Are Startled by This Magnetic Material That ‘Freezes’ When Heated

Physicists Are Startled by This Magnetic Material That ‘Freezes’ When Heated

When disordered magnetic materials are cooled to just the right temperature, something interesting happens. The spins of their atoms ‘freeze’ and lock into place in a static pattern, exhibiting cooperative behavior not usually displayed. Now for the first time, physicists have seen the opposite. When fractionally heated, the naturally occurring magnetic element neodymium freezes, turning … Read more

What Is The Hottest Temperature in The Known Universe, And Could We Achieve It?

What Is The Hottest Temperature in The Known Universe, And Could We Achieve It?

From what we know about our Universe, the coldest possible temperature is ‘absolute’ zero degrees Kelvin, or -273.15 degrees Celsius (-459.67 degrees Fahrenheit). But what about the hottest possible temperature? Physics is a little fuzzy on what the absolute hottest of hot looks like, but theoretically speaking, such a thing does – or at least, … Read more
