So we have to put everyone who dares to imagine down about it?
I see value in sharing a wild idea purely for the inspiration it may give others to think about things from a unique perspective. A lot of great science started as a strange idea.
What's the value in """daring to imagine""" about cosmology? This is nothing more than reality based fan fiction.
>A lot of great science started as a strange idea.
Disagree. A lot of great science started with "This weird math I'm doing is the only way to fit this data", which is an extremely different thing.
Do you not think physicists and cosmologists and their nerdy friends have thought of wild ideas? Do you not think undergrad students spend drunken friday nights theorycrafting universes?
It's pretty disrespectful to "why don't you just" a profession without showing that you at least did your homework first, or that you have looked at whoever definitely asked that question before you.
There are people in this post reinventing Tired light and Aether based theories for crying out loud, theories with fairly conclusive reasons we abandoned them.
When you just ass-pull theorycrafting without any of the fundamentals, all you do is talk in circles. It's no better than all the dumb "the brain is like a computer" arguments by analogy in neuroscience posts.
It's not even wrong.
We live in a world where the people who had to cheat off me in high school biology angrily insist that the vaccine doesn't work. Do we really benefit from playing such anti-scientific games?
Thank you. It's good to know I'm not the only one who feels disrespected from people on the sidelines who clearly never opened a cosmology textbook.
It's one thing to ask curious questions, but "why don't you just do the thing that was ruled out 100 years ago" and expecting a detailed rebuttal is a bit rich. It's like asking "why don't they cure cancer by cutting it out of the body". Or "why don't you just apply basic set theory to P=NP".
It's always the same on these HN threads about cosmology. Even worse with dark matter, probably because you can understand rotating curves with high school physics. No one ever invents or roots for fringe theories on baryonic acoustic oscillations in the angular power spectrum of the cosmic microwave background.
I'm not nearly as bothered by people typing out what they themselves admit are essentially physics fantasies (especially when prefaced with "I'm not a physicist" or the like), as by people who try to convince readers with even less exposure to physics that some alternative to good theories is clearly better but that the powers that be of theoretical physics are somehow suppressing it, and then clearly have little understanding about how the good theories work. There's a lot of that, especially in DM threads.
