Scientists have turned light into a frictionless fluid that acts like water

Light only travels in straight lines, or does it? Scientists have known for centuries that light is composed of waves, but the fact that light can also act like a liquid, that is rippling and spiralling around obstacles like the current of a river, is a much more recent discovery that is increasingly an area of extensive research. However, as you’d expect the “liquid” properties of light only emerge under special conditions when the photons that make up the light waves are able to interact with one another.

Krakatoa has just erupted. The Earth is doing a really good job of reminding us that we are just guests here

🏺 The child Krakatoa has just erupted few hours ago.

“This is Anak Krakatoa as the locals call it. Son of Krakatoa. Highly explosive magma. Seems it will now start to rebuild itself. The big eruption had destroyed most of the previous cone. It collapsed as the magma chamber emptied creating a tsunami. The real violent explosion was when seawater then entered into the empty magma chamber turning into steam and expanding thousandfolds” Andy Sanders, one of our members, Thank you Andy.
