Blink and you’ll definitely miss it. Scientists have measured the shortest interval of time ever recorded, clocking how long it takes a particle of light to cross a single molecule of hydrogen. The ...

Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth ...

The time it takes for a single particle of light to pass through a hydrogen molecule is now the shortest duration ever measured. This interval was about 247 zeptoseconds, or trillionths of a billionth ...

Hydrogen (H2) is an extremely simple molecule and yet a valuable raw material which as a result of the development of sophisticated catalysts is becoming more and more important. In industry and ...

Update 2: some points from Robert Freitas This is good research but it was not mechanical so not mechanosynthesis. The donation step was site specific but not ...
