For the second time this year, physicists at the Advanced Laser Interferometer Gravitational Waves Observatory (LIGO) are giddy with excitement. They’ve just confirmed the second detection of gravitational waves, ripples in the fabric of spacetime proposed by Albert Einstein a century ago. It seems we’ve officially entered the age of gravitational wave astronomy.
Earlier this week, we heard alarming reports of a “significant” nuclear waste leak at Hanford, the largest radioactive waste dumpsite in the country. Should we be worried? Absolutely. But mainly because this is a symptom of a much bigger problem that’s been festering for decades.
