Video Post: Some interesting and inspiring Neil deGrasse Tyson clips

I love feeling inspired. I love feeling moved. I love feeling connected. Watching these videos allowed me some of that this morning because it motivated me to take my fiance and our dog out on a nature walk. We got Lost in the nature preserve and it ended up taking about 2 hours to get out but I still feel it was worth it. The journey was awesome and to me that is what matters.

Did Andromeda crash into the Milky Way 10 billion years ago?

The Milky Way Galaxy,  composed roughly out of 200 billion stars, a part of a group of galaxies called the 'Local Group'. Astrophysicists theorise that most of the mass of the Local Group is invisible, made up of so-called 'dark matter'.


"For many years scientists have believed that our Galaxy, the Milky Way, is set to crash into its larger neighbour, the Andromeda Galaxy, in about 3 billion years’ time and that this will be the first time such a collision has taken place. But now a European team of astronomers led by Hongsheng Zhao of the University of St Andrews propose a very different idea; that the two star systems collided once before, some 10 billion years ago and that our understanding of gravity is fundamentally wrong."
