Bound to the radio spectrum?! Most astronomers work with more energetic photons than the puny things you get get from radio sources. Talking about being bound to the entire electromagnetic waveband is more correct, but we've not been bound to any narrow subset of it since like the 1930's.
Also, arguably the first non photon astronomical detection was the detection of neutrinos from SN1987A by Kamiokande, Baksan and IMB. There's also cosmic rays that we've been detecting for ages, but they don't really point back toward anything so it's really hard to argue you're doing astronomy with them.
- guerrilla 5y agoI'm pretty sure they meant electromagnetic spectrum. Gravitational waves moves us beyond that.
- ashvardanian 5y agoSure, electromagnetic waveband is exactly what I meant, just phrased it in more accessible terms. AP is my academical background. I didn't think I could contribute much there, so I quit even before LIGO was constructed. Now it looks interesting again :)
