How Rare Earths (What?) Could Be Crucial in a U.S.-China Trade War
Chinese companies dominate important parts of the global supply chain. The Australian C.E.O. of one alternative source of key minerals says her firm can’t fill the gap.

Do you know that each second about 100 billion neutrinos from the Sun cross every squared centimeter of your body?
They have to be very close to other particles to interact with them, and the atoms in our body are mostly empty space.
BUT, neutrinos can destroy a star!!

The Year in Physics
Physicists saw a black hole for the first time, debated the expansion rate of the universe, pondered the origin of time and modeled the end of clouds.

Has physicists\’ gravity theory solved \’impossible\’ dark energy riddle?
Cosmologists don’t enter their profession to tackle the easy questions, but there is one paradox that has reached staggering proportions.
Since the big bang, the universe has been expanding, but the known laws of physics suggest that the inward tug of gravity should be slowing down this expansion. In reality, though, the universe is ballooning at an accelerating rate.

Einstein was right: space and time bend
The early results from Gravity Probe B, one of Nasa's most complicated satellites, confirmed yesterday 'to a precision of better than 1 per cent' the assertion Einstein made 90 years ago - that an object such as the Earth does indeed distort the fabric of space and time.

Einstein was right: space and time bend
Ninety years after he expounded his famous theory, a $700m Nasa probe has proved that the universe behaves as he said. Now the race is on to show that the other half of relativity also works.
