Interesting remarks about this week's updates..Thought you'd all be glad for both of them
In relation to Dark Matter, another major factor in gravity and unseen particles are photons. These are known small particles that come from many things, stars being one of them. Like Dark Matter, they haven't been known to exist, or have been provent to exist for some time, but sometime earlier this year, according to my Physics teacher, their actual weight was discovered. This, like Dark Matter, has opened the floodgate to a new aspect of Physics, one that is much more complex than the physics we see in our ordinary day lives.
