Back in March, the science world celebrated as scientists declared the first finding of gravitational waves; a smoking gun for the Big Bang. Researchers consider than in a time period durable 10-34 seconds, the Universe stretched 100 trillion trillion times until it touched the huge size of… a marble. The gravitational waves come from variations of background radiation from this inflation age. With as excited as everybody was about that announcement, how much do we actually know about the expansion of the Universe? In the newest video for Veritasium, Derek Muller describes some of the major misunderstandings that people have about the Universe:
-How can the Universe inflate faster than the speed of light if Einstein said not anything could?
-If objects are stirring apart faster than the speed of light, how do we even obtain the light to see it?
-How did the Big Bang occur only 13.8 billion years ago if the visible Universe has a diameter of 93 billion light years?
-The Universe appears to be infinite, so how can there be one minute initial point?
-If there’s nothing outside the Universe, what is it growing into?
