There is a stream of viruses circling the planet from which each day 800 million cascade onto Earth
Trillions upon trillions of viruses fall from the sky each day. Scientists have surmised there is a stream of viruses circling the planet, above the planet’s weather systems but below the level of airline travel. Very little is known about this realm, and that’s why the number of deposited viruses stunned the team in Spain. Each day, they calculated some 800 million viruses cascade onto every square meter of the planet.
