Existential risk is the theory a future event could lead to a global catastrophe and consequently the end of life on Earth. Josh Clark is a published author and the presenter of the scientific podcast “Stuff You Should Know” and fears a future scientific test has the potential to mark the end of the world. Mr Clark revealed during a guest appearance on Big Think’s “Think Again” podcast how another experiment similar to the first nuclear detonation could happen again in the future.
The former anthropology student detailed how he feared risks could be taken in the name of science that could have grave consequences.
He said on March 17: “There’s this idea among the scientific community that there is no such thing as going too far and that is dangerous.
“The first nuclear detonation was considered an existential risk because we were not sure what would happen.
“We are developing technology that, if you couple it with human’s idea that ‘everything will work out’, we are going to end up blowing ourselves up.
