What happens to the laws of physics if a fundamental constant turns out to be not a constant after all?   The 'magic number' known as the fine-structure constant, called 'alpha' by physicists,  appears to vary throughout the universe, according to a team of astrophysicists.

That means the laws of physics would vary throughout the universe also.

The arXiv preprint describes how they determined that the fine-structure constant 'alpha' varies by measuring light from a quasar as it red-shifted due to universal expansion.
In case you do not easily panic, you may have missed the story that two asteroids were passing close to Earth yesterday.  Not to worry, it happens all of the time, but because their existence was only discovered Sunday by the Catalina Sky Survey, people were concerned.

The 50-foot 2010 RX30 came within 154,000 miles of Earth, just over halfway from here to the moon (0.6 lunar distances if you want to impress your friends), yesterday morning and then 2010 RF12, about 30 feet in size, came within 50,000 miles of Earth yesterday afternoon.
