The Universe is not expanding. Substantivalism is nonsense. H_0 is gravitational redshift.

In General Relativity, spacetime itself is described as a single 4-surface (a four-dimensional manifold with a Lorentzian metric) Using the generalized definition of an n-surface (where an n-dimensional manifold is treated as a single geometric object), how many surfaces does a single four-dimensional pseudo-Riemannian manifold constitute? The answer is 1. The relationship between mean density, surface density, and the radius is ρ = 3σ / r For a manifold with only 1 surface, σ is a constant. If 3σ is a constant, ρ ∝ 1/r What this means is that for a constant surface density, there is a 1/r distribution of matter.

I know the Pope is supposed to be infallible and everything, but data centers do not require enormous amounts of water. There are occasional, minor water issues with data centers, but it's something vastly distorted by the press. In this and so many other ways, it appears the only education the Pope has on AI comes from anti-AI activists.

@ElunedsSong @fermatslibrary The shell theorem was instrumental, but ultimately, GR has better tools (Birkhoff's theorem, Misner-sharp relation etc). There is no such thing as a shell or enclosed mass. Gravitational boundaries are arbitrarily imposed by humans. It's all one continuous manifold.

@RobinWeep @fermatslibrary This is commonly referred to as the 'shell thoerem' and was figured out by Newton, in the same work that he introduced his laws (inverse square law) in the first place.

American physicist Edward Witten explains why it wasn’t until Einstein's work that we fully understand the reason behind the inverse square law, and why it's specifically a square rather than some arbitrary decimal 1 / distance² vs. 1 / distance¹·⁷⁴⁸²²⋅⋅⋅

Most dust grains are no larger than a micron, but let’s say we go for a micron size silica particle, which is significantly larger than the median particle. At its mass and at a velocity of 0.9 C, you get 133 joules of kinetic energy, which is about as much as a bullet. So no, “several nuclear bombs going off” is total bullshit for the vast, vast majority of particles an interstellar craft will encounter

Right. This is just one of *many* such issues. You're required to go at a speed so fast that a tiny dust particle colliding with your ship is equivalent to several nuclear bombs going off, and there is no real way to do maintenance in interstellar space.

@BasqueOli Everyone always calls me crazy but I see no reason why we need to drive faster than 25mph. At 25mph you can avoid any collision and still drive from NY to LA in 5 days.

I have a theory that animals like deer treat crossing a busy highway similarly to crossing a river. I don’t buy that deers are too stupid to find the bridges. I think the complaints about cost are also funny given how much useless shit this country spends money on.
Give A Shit About Nature@giveashitnature

Wildlife-vehicle collisions cost the US around $8 to $10 billion every year. 200 human deaths, 26,000 injuries, and about a million animals dead. A standard wildlife overpass with fencing costs as little as $5 to $10 million. If the US spent $8 billion a year on them, we could build a 800+ a year. Banff National Park built 44 crossings over three decades. Wildlife-vehicle collisions there dropped by 80%. The crossings paid for themselves in avoided property damage and injuries within a few years. The evidence is strong: wildlife crossings save animal lives, reduce injuries, and often pay back substantial costs over time. The remaining challenge is finding the will to build them.

Just learned about the concept of a “telescope ranch” in Texas. People pay to have their $10,000+ telescope rigs set up in the middle of TX to avoid light pollution. Every night the roof rolls back off the warehouses. Then you can remote in to your telescope and use it from anywhere in the world.

Light travels along null geodesics. ds² = 0. But the emitter and observer sit at different values of g_tt, so their clocks tick at different rates. Along the radial null path, that difference accumulates as a potential difference: d ln(1+z) = dΦ/c² so 1+z = exp[ΔΦ/c²] = (1 − r/rₕ)^−1/2 That is why more distant sources have a larger gravitational redshift. This accumulation is ignored in mainstream cosmology. A distribution of ρ∝1/r exactly matches the Hubble shift.

@RobinWeep My understanding of the expansion has nothing to do with individual bodies of mass changing their size. That only happens as soon as they are colliding with other bodies of mass. The expansion has to do with how these bodies collectively are on a path of spreading out.

It's heart breaking for someone like myself, someone that's already considered a crackpot. But I wrote a book about my shit in 2017! I've stayed consistent throughout all of my research. Now, everyone assumes I'm suffering from an AI induced psychosis but the LLMs all disagree with me too. lol It's honestly just a sign that mainstream physics is a complete disaster.

Yes, but there are also many unsolved mysteries in modern physics. Obviously, something is wrong. Dark Matter and Dark Energy constitute 95% of the universe. The Hubble tension is also more dramatic than the mainstream would like to admit. General Relativity is difficult. It's not just the math. The philosophy behind finding a solution to the field equations includes deep reflection about the nature of the system you're trying to describe. Finding an ansatz is what makes it so difficult. Einstein assumed the universe was homogeneous, as do most modern cosmologists. This is an understandable mistake, but a mistake nonetheless. Mass density is scale dependent and there are no gravitational boundaries. If you can grasp that, you can understand why gravitational redshift was overlooked.

@EV_Trapper Modern humans are so weird. I can understand wanting to play ball or avoid snakes, but the levels of lawn maintenance in this country is seriously psychopathic.

@MericaCulture The loonies are in the right though. It's absurd to think Lewis and Clark did anything meaningful when there were are millions of people living in the US for thousands of years.

The sad reality is that building something so unabashedly American in 2026 is near impossible. The commies who run Minnesota and Wisconsin would inevitably insist on including Sacagawea and we'd get never ending protests by Indians over "stolen land".

I think we need to build this. I designed this below image, representing Lewis and Clark on the Mississippi in the style of Argonath. At $1 Billion or more, I think it can be done.
