<span>Miller Urey experiment's purpose was to test the chemical origin of life under the conditions supposed to be present on the early Earth.
</span>The scientists Miller and Urey heated a mixture of water<span>, </span>ammonia<span>, </span>methane<span> and </span>hydrogen<span> in a sterile flask until it evaporated water to produce water vapour. </span><span>Electric sparks were passed through the mixture of </span>water vapour and gases, simulating lightning. The experiment was done during one week. After a week, the contents were analysed and Miller and Uray proved that <span>several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere.</span>
To solve the exercise it is necessary to use the reciprocal Lorenz factor of the special theory of relativity with the pulse rate.
