The watery area in question is about 20 kilometers in diameter, and while depth can’t be determined, the deposit would likely have to be at least a meter thick to produce the reflection observed. So at a bare minimum we’re probably looking at a serious quantity of water, on […]

Humans can hear the difference between hot and cold water being poured. This is because the viscosity of water will go down as temperature increases. As you heat water, it will have more energy and its molecules will be less likely to stick together. Less sticking together results in smaller particles and less force per […]
