The Universe & Its Physics

This blog is a blog by up-and-coming astrophysicist, Kevin P. Kelly. Physicists like Dr. Neil deGrasse Tyson, Dr. Sean Carroll, and Dr. Brian Greene are his inspirations to achieve a PhD. in physics or astronomy. This blog is deticated to topics in, space and time, relativity, gravity, quantum mechanics, astrophysics, astronomy, stellar evolution, galaxy formation, and the sizes of bodies of mass such as stars, galaxies, galaxy clusters, superclusters, and ultimately, the size of the universe.

George Musser, in this short video, gracefully breaks down the heady topic of what a field actually is.

There are many fields in Physics. Gravitational Field, Higgs Field, Gluon Field, etc. Musser, from Scientific American, explains every particle and force has its own separate field.

M31 The Andromeda Galaxy

Andromeda is an amazingly beautiful galaxy, when viewed upon at the correct wavelengths. One of my favorite cosmic pictures, amongst many. M31 is our closest neighboring galaxy. It is the closest galaxy to our home, The MilkyWay. This 'nearest' galaxy sits 200,000,000 light years away from us. For all the beginners, this means that if you got into a spaceship right now, and embarked on a bold journey for Andromeda, traveling at the speed of light, 186,000 miles per second (you would travel fully around the earth 7 time in one second at this velocity), you would not get there for another 200 million years. Yes... This is the closest galaxy..
