Does this mean neutron stars are like dwarf black holes?
We call black holes such because they emit no radiation from their inside and suck any radiation from the outside. As such, it is impossible to see anything that is inside a black hole.
Neutron stars are quite massive, enough to bend space-time such that you can see more than half of its surface. However, it is not strong enough to capture any radiation and hold on to it. The dwarf black hole analogy kinda doesn't apply.
Ok how about something that is on edge of being a black hole but kinda not. Then gravity will cause matter a bit closer to the center to collapse in on itself, causing a black hole. So lets tell physics to take a hike for a second and pretend that doesn't happen. Then the radiation would be red shifted, the neutron star that normally glows hot blue-white would glow dark red or black in the infrared, microwave or even radio. Then that would kinda be like a dwarf black hole.
edit: Now that I think about it, our universe is kinda like a dwarf black hole. Only it's inside out or something. The further we look away, like the cosmic microwave background, the more we see the effects similar to what I described.
