See the invisible and take a look at what sound waves look like thanks to a cool high-speed photographic technique called Schlieren Flow visualization which shows the change in air density as sound waves travel through the air. The technique was developed by German physicist August Toepler between 1859 and 1864.

Wrap your head around this – a new way of thinking about time and space from Rob Bryanton, author of the book Imagining The Tenth Dimension.

The average person has barely gotten used to the idea of there being four dimensions: how can we possibly imagine the tenth?
Well watch this…is it closer to science fiction or science fact?
Most of what we understand about the physical universe comes from light and vision but we are learning new information that leads scientists to believe that the universe isn’t silent. Although we haven’t had the technology yet to hear the actual sounds of space, scientists project that we’ll be able to hear actual audio from the universe within the next few years.
