Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It’s the reason some people use masks to make sure light doesn’t wake them while they sleep. Now researchers at UCLA have […]

The Fermi space telescope has spotted the youngest-ever millisecond pulsar – a fast-spinning cosmic “lighthouse” that is the leftovers from a supernova. It is the first pulsar from a globular cluster seen to shine in the highest-energy light we know of: gamma rays. The pulsar’s gamma-ray brightness and evident youth challenge our notions of how […]

If Nassim Haramein generates one or more equations that explain a mystery and that make testable predictions, and this is verified during peer review, then he will be accepted, as Einstein was. Scientists aren’t mean, they just find that rigorous debate about actual facts creates a higher standard for what they accept. They don’t argue […]
