light in the coldest place on Earth

By Nic LazTuesday, Oct 01, 2019


I consider myself a scientific and knowledgeable person, and I thoroughly enjoy those moments when my understanding of the world gets an upgrade – as well as the included ‘Ah-a!’ moments that happens in these moment, taking my breath away.


Recently I had that happen three times in one moment – incredible I know – with the discovery that over a decade ago the Harvard Professor Lene Hau has slowed a beam of light to the speed of a person crawling along. That was the first ah-a moment!


Fueled by my curiosity, I dug deeper into this research and found that this was made possible by creating the coldest place in the world, within a Bose-Einstein condensate that exists at almost 0 Kelvin (−273.15° Celsius) ! Second ah-a!


All of this is possible because of using multiple lasers blasting the particles, and that makes it get that incredibly cold 100 times faster, making me Third moment of ah-a!


And today I just discovered that MIT recently are able to create these unbelievably cold environments even faster than before – the endless march of science continues to feed my curiosity and hopefully yours as well.

Did something recently give you a ‘ah-a!’ moment?
