Why not admit that Hubble is lost and gone ?

The thing I love about this board is that it has an international membership.

Often times I have to wait for a response during a debate here because the person I'm having the conversation with is asleep due to the fact that they're on the other side of the planet.

While it's midday here, it's midnight somewhere else. Hence, a round ball in space.

I once read a (stupid) explanation for that. You see, the sun is really tiny and turns around in circles above our flat Earth, only able to illuminate a part of the disk at any one time, like a spotlight, thereby giving the illusion that we're a sphere revolving around a really big sun.
It's no use arguing with Flat Earthers, really...

And that explanation was created in the 19th Century by someone who wanted the earth to be flat, like in the Bible, but had to find a mechanism to explain the established fact that there were distinct regions of day and night.

Even the ancient civilizations like the Sumerians, Babylonians and Egyptians, who thought the earth was flat, knew that the sun appeared to revolve around the earth, not circle around on a plane some distance above it and parallel to the ground. That's because they were actually quite clever. They simply didn't yet have enough information to discern the true form of the Earth. They simply couldn't travel far or fast enough to see evidence of the curvature of the Earth. But what they could discern and measure about the apparent movements of the sun, moon, stars and planets was certainly putting them on the right track.

The zetetic cosmology, on the other hand, was invented by people who were distinctly not clever. They invented the most specious and poorly investigated arguments they could think of and stopped well short of any in-depth geometric analysis that would have shown the impossibility of their cosmology. They had what they wanted: a radically contrary cosmology that let them imagine that they were great minds who had uncovered a deep truth about the universe.

The ancient civilizations made the best guess they could with all the available evidence, and as new knowledge was acquired in later generations, the same tradition of scholarship led them to revise their model toward greater and greater fidelity. The new flat-earthers, on the other hand, ignore all evidence that disproves their fantasy.

Wonder how a spotlight always looks circular even when it's not aimed directly at you. Or how it manages to drop below the horizon.

I am blessed to live on the Central California coast. The Pacific Ocean is about five minutes away by car. When I used to drive south to the Monterey Peninsula for work at 05:30 A.M. sometime the sky was clear enough to see the rotation of the earth at the crack of dawn.

On my right the sky was black over the sea, and then grew brighter shades of blue as I looked left until it went to orange, and finally a golden yellow just before the sun broke the eastern horizon.

It's a spiritual experience and a human experience because for about eight minutes I had a clear understanding that I was on a rotating planetary mass in a black sea of other planets (which were also visible low on the horizon over the ocean), circling a star that was coming into view as the earth turned. I was just a tiny moving dot on a small blue ball in space.

Very profound and humbling for sure.

Let's assume you're correct and entropy prevents a non vacuum system from being attached to a vacuum. This means that either : there is no atmosphere on the earth, or that the atmosphere continues into what we term 'space'

Given that I am breathing quite happily now, I assume that there is an atmosphere on earth, so the only remaining option is that the atmosphere continues into space. So why do astronauts, cosmonauts, taikonauts and pilots of high altitude planes need breathing apparatus?

Welcome to the board.

Let's set them Equal:

F_c = m_Earth ( V²/r ) = G m_Earth M_Sun / r² = F_g . So a little Algebra...

F_c = m_Earth ( V²/r ) = G m_Earth M_Sun / r² = F_g ....

F_c = ( V²/r ) = G M_Sun / r² = Fg !!! We can Stop right here, See The Problem??

F_c and F_g are NO LONGER "FORCES" because we just Eliminated ( " m " ) from both sides of the Equation!

Your math is wrong. You can not just strike out mass from one side of the eqasion without adjusting the other side as well. The correct equasion would be:

F_c/m_Earth= ( V²/r ) = G M_Sun / r² = Fg/m_Earth

Therefore both Fg and Fc would still be forces.

Let's set them Equal:

Fc = mEarth ( V2/r ) = G mEarth MSun / r2 = Fg . So a little Algebra...

Fc = mEarth ( V2/r ) = G mEarth MSun / r2 = Fg ....

Fc = ( V2/r ) = G MSun / r2 = Fg !!! We can Stop right here, See The Problem??

Its really good to see that physics and astronomy are not the only subjects about which you are totally ignorant.
