Fermilab scientists have been conducting experiments to look for quantum fluctuations of space and time at the smallest scale imaginable according to known physics. At this limit, the Planck length, ...
ON A human scale, an atom is inconceivably small. But size is relative. On the Planck scale—the smallest that physical theory recognises—atoms are huge. At this scale, named after Max Planck, the ...
It's notexactly Doc Brown's DeLorean from "Back to the Future," but theEuropean Space Agency's (ESA) Planck Observatory will be something of a cosmictime machine after it launches this week. Planck ...
A European space observatory that's surveying the light left over from the birth of the universe has wrapped up a big part of its mission. The High Frequency Instrument (HFI), one of two sensors ...
An artist's illustration of the Planck spacecraft, a European Space Agency probe designed to study the Cosmic Microwave Background (CMB) – the relic radiation from the Big Bang. It mapped the ...
