What happens if Gulf Stream stops?
What happens if Gulf Stream stops? That could mean rising seas and a hotter Florida. A weaker Gulf Stream would mean higher sea levels for Florida’s east coast. It could lead to colder winters in northern Europe (one reason many scientists prefer the term climate change to global warming). Is it better to live on […]

Do gamma rays travel faster than light?
Do gamma rays travel faster than light? Although the energy inherent to light is quantized into discrete energy packets (a.k.a., photons), there are some properties shared by all forms of light. Light of any wavelength, from picometer-wavelength gamma-rays to radio waves more than a trillion times longer, all move at the speed of light in […]

Which principle is used in rocket?
Which principle is used in rocket? The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses is explained by the same physical principle—Newton’s third law of motion. Matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains. Another common example is the recoil of a […]
