A Logarithmic Map of the Entire Observable Universe

On this day in 1935, astronaut Harrison Schmitt was born. He traveled to the Moon on Apollo 17, becoming the only trained geologist to walk on the lunar surface. https://t.co/nM7cGbqFNX

Looking to get into astronomy

Any one have any recommendations for good telescopes? I’m willing to spend some money on it but I don’t want to go overboard on it and buy a telescope that’s too powerful for causal astronomy? Any help Is appreciated:)

Q: What makes black holes special among stellar remnants?

So, I’ve done some reading on stellar life cycles, and I have one question: What if black holes were way more “normal” than we think? (Assuming the answer is well understood) What stops this from being true? Let me explain, as stars get more and more massive, they collapse into different things of increasing density. From white dwarves, to neutron stars, to possibly quark stars and whatnot. What if black holes were just “normal” star remnants that happened to be dense enough to stop light from escaping them at a certain radius? What is different about them that makes them odd? I should say, I’m definitely not a black hole guy, it just seems to be more “logical”, to me, than something capable of universe leaping or wormholes or some other things I’ve heard.
