Atomic scientists reset the Doomsday Clock on Tuesday, moving its hands to 90 seconds to midnight - closer than ever before to the threat of annihilation. Skip to main content.

Humanity is closer to destroying itself, according to atomic scientists who revealed on Tuesday that the famous “Doomsday Clock” was set to 89 seconds to midnight — the closest it has ever been.

The clock was established in 1947 by Albert Einstein, Manhattan Project director J. Robert Oppenheimer, and University of Chicago scientists who helped develop the first atomic weapons as part of ...

The Doomsday Clock is a metaphor for how close the world is to being inhabitable for humanity. Scientists just set the new time for 2025.

Atomic clocks were believed to be a huge improvement on quartz clocks because of the atom's stability. In the atomic clock, a quartz crystal oscillator is combined with an ensemble of atoms.

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

That's why atomic physicists at NASA want to build a more precise, more autonomous atomic clock. Sponsor Message. The team hopes a prototype will be ready by late 2025. Related reading: ...

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and help put global time on a more accurate frequency.
