Harvard physicist suggests Earth needs treaties with extraterrestrial civilizations to avoid a cosmic catastrophe
Harvard physicist Avi Loeb warns alien civilizations could have the ability to make machines capable of destroying Earth
Loeb uses the example of a particle accelerator that could create dark energy energy explosion that would destroy everything in its path
In order to keep the peace in space, Loeb suggests interstellar treaties
The treaty would follow the same laws as the 1963 Nuclear Test Ban Treaty
This banned countries from testing nuclear weapons on Earth and in space
