Some scientists believe microorganisms from outer space hitched a ride to Earth aboard an asteroid or a comet, since life arose during a period when our planet was pelted with space rocks. Other scientists say life arose from spontaneous chemical reactions on Earth.

Now, chemists in the Czech Republic say they have evidence to support a theory that combines both ideas–that an asteroid impact triggered the production of RNA bases, the building blocks of life’s genetic code.

To test the theory, the researchers simulated the energy of an asteroid impact on Earth using the Prague Asterix Laser System, a powerful laser that can generate around a billion kilowatts of energy at its peak, the Associated Press reported. (1)

Formulate a hypothesis.
Test it in “similar” conditions.
Prove it “correct”.
