Einstein was awarded a Nobel prize for his explanation for how light can be described as being made up of individual particles of energy under certain conditions.
For 60 years, physicists thought they knew exactly how coherent a laser could get. Now the ultimate quantum limit to laser coherence has been found, and it’s much much bigger than anybody thought.
We identify an experimental method which could finally reveal whether objects much larger than atoms - such as humans or animals - can exist in several places at once.
If it’s impossible to accurately predict the future then there may be limits to how smart artificial intelligence can become.
