Neil deGrasse Tyson Explains the Science Behind Rainbows in Touching Orlando Tribute

Powerful tributes and memorials to the Orlando, FL, shooting victims continue to spread and grow, like a series of tweets about rainbows by Neil deGrasse Tyson.

The famed astrophysicist wrote a series of eight tweets on Tuesday night to discuss how we see rainbows and the colors that came to be synonymous with them. As Tyson begins, he talks about the scientific reasoning as to how we see rainbows and why Isaac Newton came up with the colors of it.

Tyson went on to make a Star Trek reference before ending with how the colors of the rainbow are found on flags — like the rainbow flag that stands as a symbol for the LGBT community.

It's a short, simple, scientific tribute that is just another way of people everywhere taking the time to remember the victims from Orlando.
