When gravity breaks
March 2, 2013Gravity attracts all objects towards each other. In the very beginning of the universe, after the Big Bang, gravity pulled atoms together to make stars and planets. Once the stars and planets had formed, gravity kept the planets in orbit around the stars, and moons orbiting around the planets. And on each planet that is large enough, gravity keeps an atmosphere around the planet.
On Earth, gravity keeps the air around us (and everything else) from drifting off into space. Gravity also causes things to fall to the ground, and causes the ocean’s tides, and causes hot air to rise while colder air falls (which in turn causes wind).
So explain this …

Rubber bands vs Water Melon
December 31, 2012Isaac Newton was a smart guy. He discovered heaps of things including the law’s of motion.
Newton’s second law of motion states that F = ma, this means that the force something applies is equal to it’s mass multiplied by its acceleration.
Now that we have got the Science out of the way … In the tradition of ‘Killer Whale vs Seal‘, ‘Lion vs Buffalo vs Crocodile‘, ‘Shark vs Octopus‘, ’Leopard vs Porcupine‘, ‘Hornets vs Honey bees‘, ’Salmon vs Grizzly Bear‘, ‘Hippopotamus vs Crocodile’, ‘Polar Bear vs Walrus Colony’, ‘Giraffe vs Giraffe‘ and ‘Caterpillar vs Frog‘ and ‘Frog vs Poison Newt’, here is ‘Rubber bands vs Water Melon’:
