Obviously there's the famous pentagram and the Superman sign, but can you think of anything else? I'm stumped. Thanks in advance!
I would always say, if in doubt, don't feed. Missing a feed will not really impact a healthy horse, but feeding a nervous horse could!
Actually it's not the mass, but the density of the mass of matter that depicts how much gravity it has. Take for example a black hole. At one point in time a black hole was just a giant star that had x amount of gravity because of it's size and density. But still a star. And when it burned out and collapsed on itself, the density became so extreme that it's gravity started drawing other objects to it. This extreme gravity didn't exist until it collapsed into a smaller, denser star. For instance, which has more gravitational attraction to the earth, a ball of aluminum or a ball of lead the same size?
