Dark Matter Mug
1. Unprovable hypothesis that since galaxies and galactic clusters don't have enough mass to produce enough gravity to spin the way they do, that there thus must be invisible matter hiding that's making it all work. 2. The observation of the universe sometimes fails to follow the known laws of physics, so instead of theorizing that there must be more laws we've yet to discover, scientists have instead decided to push forward the idea that invisible masses must exist, and thus explain away the discrepancies and gaps in our knowledge. 3. Science akin to religion in that nothing at all proves it, but lots of people believe it because it explains something that was hitherto before difficult to understand. 4. Theory regarding matter and gravity that seems to make sense of Newtonian physics when it fails us, but in doing so introduces a concept that is completely ludicrous. 5. Alternative hypothesis to how the universe works to the much more logical MOND theory, or variations thereof. 6. An example of lazy science. 7. The greatest example of how extremely intelligent people can at times be completely clueless, lacking in all common sense.

my friend loves funky monkey mug

Great idea to be able to offer this quality mug. I wish it would have come with the full text including examples listed on Urban Dictionary but I do love the mug. Just bought my 2nd one. Packaging is duarable and perfect for rough transit.
¡Soy profesora de español y lo voy a usar en mi clase en la universidad!
I wish the text on the back wasn’t so small—if I had to order it over again I would’ve inquired as to whether the words could be enlarged so it filled up more of the “white space” on the back
You guys are fantastic! Will continue to do business with you. Thank you so very much.
