"The astronomer nowadays uses light to space out the distances he measures. Light travels at 186,000 miles a second. It takes a second and a third to reach us from the moon and eight minutes from the sun. Yet the sun is quite close, compared with the other stars. The nearest of them is over four light-years away, which means that the light we now see it by was emitted by the stsr over four years ago. The remotest parts of the universe at present known to astronomers are thousands of millions of light-years away." - H.G. Wells, The Outline of History, pg. 15
In other words, we cannot trust our senses.
