Re: Silly question...
Both are affected by gravity but
- neutrinos hardly interact and go 'straight out'
-light will interact with any matter in and around the supernova and will take some time to get out. How long depends on a lot of detailed understanding that we might not have got right.
for example photon diffusion time (getting absorbed, re-emitted in random walk style ) from the sun's core to its surface is estimated to be about 170,000 years, despite its radius being about 2.3 light seconds.
