1 week agoAsk Ethan: Do gravitational waves redshift like light does?
Gravitational waves, like light waves, can experience redshifts and blueshifts due to various intervening effects during their transit.
As a science communicator, I don't think a week goes by without a press release hitting my inbox informing me of astronomers finding some new record-breaking object. Sometimes it's the smallest planet yet discovered or the most iron-deficient star. But a very common claim is a distance record: the farthest galaxy from Earth ever seen, for example. When it comes to these sorts of record breakers, I have complicated feelings, built over decades of writing about them.
