I will keep this short and sweet...
Katy Perry has an Album called Roar coming out with a song called "Burning Baby Blue". Let me say this another way: Scream its burning Baby Blue.
There was a Dominos Pizza commercial in which two kids bring an old guy a pizza and say "see its hot and ready" the old man replies, "well paint me blue and call me babe". Video Remember the song call me Baby where the singer says "Its hard to look right, at you baby", while she was washing a blue car?
You may not know it but there are objects in space that burn in infra-red, they are hard to look at with the naked eye, impossible actually. They are So Hot that they cannot be seen with the naked eye, they can only be seen with an infared telescope and when viewing them in that manner they appear to be blue, the hottest heat.
A scientist came out a few days ago and said that there is a blue-hot object approaching the planet which will cause massive destruction. This just happens to be covered in my new eBook also.
