What the detection of gravitational waves teaches us about patience
Like many homo sapiens on planet Earth, I was thrilled by this month’s announcement of the first direct detection of gravitational waves. This finding surely ranks with the greatest scientific discoveries of the past 200 years.
Nobody in the scientific community doubted the existence of gravitational waves. They are absolutely required by Albert Einstein’s theory of gravity and have been indirectly inferred from other astrophysical observations. The great achievement here was the construction of the most sensitive scientific instrument ever built — able to measure changes in distance a thousand times smaller than the nucleus of an atom.
We now have a new sense organ with which to fathom the cosmos.… Seguir leyendo »
