An elusive particle that first formed in the hot, dense maelstrom of the early universe has puzzled physicists for decades.

When we go backwards in time through the history of the cosmos, the distances and volumes shrink, while the average energy ...

The Big Bang theory suggests that the universe began as a hot, dense point, expanding into the cosmos we observe today.

For nearly 10 years we’ve been operating in a search mode, and any day we could make a discovery,” said Gray Rybka, a ...

In their measurements, the difference between a slowed photon and a "regular" photon was just a few millionths of a meter, but it demonstrated that light in a vacuum can be slower than the ...

Then again, in 1961, scientists predicted that no transistor on a chip could ever be smaller than 10 millionths of a meter -- and on a modern Intel Pentium chip they are 100 times smaller than that.

Meteor showers are produced when swarms of tiny particles of dust, most just microns — millionths of a meter — in size, burn up in the Earth's atmosphere. However, lurking among all the dust ...

The potentially lethal poison ricin was found in the home of Southport suspect Axel Rudakubana by police, adding charges of ...

“These ‘practice missions’ are miniaturized – our mock asteroids are only roughly a centimetre in size – and the flight is short-lived – just a few millionths of a second,” Moore explains. “But that’s ...

Using the light-emitting particles, researchers were able to track displacements as small as billionths of a meter, and rotations as tiny as several millionths of a radian at a rate of 1000 times per ...
