This animated video describes how Einstein’s field equations led to the cosmological constant, which was later shown to be incorrect.  However, Friedmann and Lemaitre found solutions to Einstein’s equations, if the universe was still expanding.  Hubble found evidence from the red-shift of galaxies that the universe...

Looks at the impact of global warming and to what extent humanity has contributed to this.  The animated video explains the greenhouse effect, and how greenhouse gases can absorb infrared radiation and then re-emit it.   It also looks at how the oceans become more acidic when carbon dioxide is absorbed from the...
