According to Big Bang Theory all the matter in the Universe once fitted into a space less than the size of a pin head.
Get hold of a pin. Take a good look at it. Now ask yourself: "Do I really and truly believe that the mass of between 1 sextillion and 1 septillion stars (that's between 1,000,000,000,000,000,000,000 or 1,000,000,000,000,000,000,000,000 stars) could fit into this pin's head?". It doesn't sound very plausible does it? And that doesn't include all the other stuff floating around - including dark matter and dark energy that make up the bulk of the Universe. Are scientists playing you for a sap?
