There are 2 types of god. Only one is within the boundary of science.

Science is about natural law, while religion is about ethics. As long as you keep these two separate, Kaku says, there's no problem at all. Problems arise, however, when the natural sciences begin to "pontificate upon ethics" and when religious people begin to pontificate about natural law. Albert Einstein believed in the "god of Spinoza" — not a personal god, but one who has set order and harmony in the fabric of the universe. "You can put the laws of physics as we know them on a simple sheet o...

Student of the stars: How do you become an astronomer?

What's the difference between an astronomer and an astrophysicist? NASA's Michelle Thaller explains that these terms are used interchangeably: both are physicists who study objects and phenomena in the sky. How can you become an astronomer? There is a defined path to take: Do an undergrad degree in astrophysics, physics, mathematics or computer science, then complete a doctorate in astrophysics. You could also work with astronomers by studying engineering and building telescopes. In this fascina...

Scientists detect tones in the ringing of a newborn black hole for the first time

If Albert Einstein's theory of general relativity holds true, then a black hole, born from the cosmically quaking collisions of two massive black holes, should itself "ring" in the aftermath, producing gravitational waves much like a struck bell reverberates sound waves. Einstein predicted that the particular pitch and decay of these gravitational waves should be a direct signature of the newly formed black hole's mass and spin.Now, physicists from MIT and elsewhere have studied the ringing of a...

Engineers developed a mathematical model of Ooblek

A favorite kitchen chemistry (and physics) experiment of kids (and adults), Ooblek is the weird result of mixing cornstarch with water. Now, MIT engineers have developed a mathematical model that can predict and simulate how the non-Newtonian fluid switches between liquid and solid depending on the pressure applied to it. From MIT News: Aside from predicting what the stuff might do in the hands of toddlers, the new model can be useful in predicting how oobleck and other solutions of ultrafi...

Is the universe a hologram? The strange physics of black holes.

Since energy cannot be destroyed, only transformed, some argue that information — arguably a form of energy — cannot be destroyed either. So then, what happens to information when it is absorbed into a black hole? Scientists don't know for certain, but some posit that is may be possible for it to leak away from the black hole over time. Black holes may hold information in a two-dimensional manner similar to a hologram, which take on three dimensions when light is shone through them. Some theoriz...

Lambs, the radiation-proof underwear company formerly known as Spartan, is now selling beanies

Earlier this year, Spartan, the French manufacturer of a silver-lined underwear designed to block EMF radiation from cell phones and wireless routers, relocated to the U.S. and raised some capital from the Los Angeles-based investment firm, Science. Now the company has relaunched as Lambs and is adding a radiation-proof silver-lined beanie to its $29-per-pair underwear already on sale in the U.S. The company’s goal is to capitalize on paranoia around the effects of cell phone radiation on health...

Researchers successfully sent a simulated elementary particle back in time

The second law of thermodynamics states that order always moves to disorder, which we experience as an arrow of time. Scientists used a quantum computer to show that time travel is theoretically possible by reverting a simulated particle from an entropic to a more orderly state. While Einstein's general theory of relativity permits time travel, the means to achieve it remain improbable in nature. None In 1895 H.G. Wells published The Time Machine, a story about an inventor who builds a device t...

100 years on: the picture that changed our view of the universe

Arthur Eddington’s photograph of the 1919 solar eclipse proved Einstein right and ushered in a century where gravity was kingA hundred years ago this month, the British astronomer Arthur Eddington arrived at the remote west African island of Príncipe. He was there to witness and record one of the most spectacular events to occur in our heavens: a total solar eclipse that would pass over the little equatorial island on 29 May 1919.Observing such events is a straightforward business today, but a c...

There’s gold in your brain — we now know where it came from

A unique, tiny grain of stardust has provided a look at the early universe. Computer simulations point to a single neutron-star collision as a significant source of heavy metals. Gold is more than bling — it's in our neurons. None If you've got a thing for gold, you'd better have some money. Not only is the precious metal beautiful, but the amount of it in the universe is finite. A new study concludes that a single neutron star merger some 300 parsecs away produced a significant amount of it. ...

A mind-blowing explanation of the speed of light

The only things that travel at the speed of light are photons. Nothing with any mass at all can travel at the speed of light because as it gets closer and closer to the speed of light, its mass increases. And if it were actually traveling at the speed of light, it would have an infinite mass.Light does not experience space or time. It's not just a speed going through something. All of the universe shifts around this constant, the speed of light. Time and space itself stop when you go that speed....
