How hot can the Universe truly get? Enter the Planck Temperature,a mind-blowing 1.416784 × 10³² Kelvin. This is not just ...

Has the temperature of the universe changed over time? When the universe began to rapidly expand after the Big Bang some 13.8 billion years ago, the temperature cooled dramatically and quickly.

By 10 microseconds, the average temperature of the universe’s contents is 3 trillion kelvins, equivalent to the energies that the Large Hadron Collider explores in quark-gluon plasmas (about 300 ...

Another contestant for the hottest temperature in the universe comes courtesy of string theorists, who say that the hottest temperature is 10 30 K, a little cooler than the contestant above.

During those very early moments of the universe, things were extraordinarily hot, and quark-gluon plasma behaves in strange ways when super-heated. This is because high temperatures will bring on ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Feast your eyes upon the first color—not the first one in this book of course, but the first color in the universe. This bright-hot glowing peachy orange didn’t exist until approximately ...

But, there is one place in the universe that makes even the coldest winter weather look positively balmy: the Boomerang Nebula, a cloud of gas and dust located around 5,000 light years from Earth ...

The aforementioned models of the cosmos, including the standard model of cosmology, have long posited the idea that the ...

The world desperately needs a room-temperature superconductor—a material that exhibits no electrical resistance at atmospheric temperatures and pressure. But it isn’t easy to find.
