An Attosecond

While not using the most, um, realistic basis for research, this graphic examining how fast the Flash is (or just Flash? I don't know) is very interesting.
But the fact that attoseconds exist is insane. Why do we need that amount of time to exist? What are we measuring in attoseconds?

Okay, some quick research proved me wrong.

• 1 attosecond – the time it takes for light to travel the length of three hydrogen atoms.
• 12 attoseconds – record for shortest time interval measured as of 12 May 2010.
• 24 attoseconds – the atomic unit of time.
• 67 attoseconds – the shortest pulses of laser light yet created.
• 100 attoseconds - fastest ever view of molecular motion
• 200 attoseconds (approximately) – half-life of beryllium-8, maximum time available for the triple-alpha process for the synthesis of carbon and heavier elements in stars.
• 320 attoseconds – estimated time it takes electrons to transfer between atoms.

Science is so small...
