Modeling Cosmic Expansion Without Dark Components (sh.itjust.works)

This post comes with a disclaimer: Claude 2 was released earlier this month, and I've been wanting to test it out. I fed in an idea and a thought experiment I've been thinking about, and asked it to help write a paper. Most of the formulas are Claude 2's work. I did try as I went along to not gaslight the LLM. I even had Claude 2 write the body of this post about it.

New theory: Our universe is slowly evaporating like a black hole!

What if cosmic expansion and weird "dark matter/energy" actually result from our universe evaporating energy over time?

A new model proposes that, just as black holes slowly radiate away mass through Hawking radiation, our universe maybe evaporating through a similar quantum process.

This gentle evaporation can explain the initial rapid expansion of cosmic inflation. As well as the later accelerating expansion we attribute to dark energy.

The theory also suggests cosmic evaporation over billions of years makes it look like there's extra "matter" influencing galaxy motions. When really it could be just total mass decreasing over time.

So could dark matter and energy be illusions caused by our universe exponentially evaporating? The maths seem to add up. But more study needed!

What do you think? Could we live in an ever-slowly evaporating cosmos? Let me know your thoughts on this crazy but kinda compelling new idea!

TLDR: I fed in my thoughts to Claude 2 and out popped a paper.

The evidence for dark matter is purely observational. From the background radiation signature to galactic collisions and rotation curves. We haven't got a single solid theory on what it is yet, but it's definitely there and was crucial in matter formation in the early universe.

I completely agree with every word, it was the observations alone of dark energy and matter that led me in this direction.

At one time I tried to describe them with an unknown fifth dimension, but later realized that's only an abstraction. Perhaps just maybe black holes and universes share this property of evaporation, which if so, would have interesting consequences.

I have the thought experiment to go along with the paper, if you'd like to see that at https://madhakker.com/ just scroll down one post. That was from when I was trying the fifth dimension angle, but it does a good job of describing a dark matter like signal in the terms of a changing mass.
