The smallest time interval ever defined. Named after theoretical physicist Max Planck (1858-1947), Planck time is 10-43 seconds; however, the only measurement ever actually made was more than twice as ...

Below these scales, our current theories about space and time completely break down. If we try to describe the universe at a time before 10 -43 seconds in its history — the Planck era — we discover ...

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, ...

The Planck mission has captured its first rough images ofthe sky, as part of its mission to measure light from the dawn of time. Planck ? a European Space Agency mission with NASAparticipation ? will ...

A spacecraft that revealed details of the hidden tapestry of the infant cosmos has had its last hurrah. Since its launch, Planck has helped scientists settle on a detailed, cohesive story of the ...
