An open letter to the Breakthrough Prize and Nobel Prize Black holes are scientist's imaginary toys to scam money and fame. Black holes are impossible to exist. Here are the reasons. I hope you guys have open minds and rational thinking, but I highly doubt. You rewarded fake gravity wave detection and fake black hole picture taking. 1. A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because the matter has been squeezed into a tiny space. This can happen when a star is dying. Wiki Before the star is dying, what is it? Does it have stronger gravity to pull light into it? Are those big stars should be black holes in the beginning? Atoms are incompressible, how can matters squeeze into tiny space? 2. A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. Wiki How can scientists take picture of a black hole that can not be seen? Science is not a story, all things have precise mechanisms. What is the precise mechanism of gravity pulling light into a black hole? If gravity can decelerate the light speed, why big and small stars have the same light speed? 3. Scientists say gravity is not a force but the curvature of spacetime. How does the curvature of spacetime pull all the light into the middle of a black hole? What is the precise mechanism?
