A universe that expands relative to the observer

[Nick Astraeus]

The game of fundamental physics is to derive as much as possible from the fewest and simplest propositions.

In the spirit of that game, here is a series of 60-second arguments, in which I address some of the major problems of modern physics, working from these two basic propositions:

(1) the universe expands relative to the observer
(2) there are multiple observers

Skepticism about one or all of these arguments is, of course, fine. But keep in mind that, in the context of this game, the ultimate measure of success is whether a single model can unite and explain the seemingly disparate problems of modern physics.

Do the observable universes need light to be observable? Do they need it to exert negative pressure on each other or can they expand without it?

I commented your short on the same topic on yt. If your observable universes need light, then we have a common ground.

There are three basic ways to observe an object:

1. You throw stuff at the object that causes it to throw stuff at you.
2. Something else throws stuff at the object that causes it to throw stuff at you.
3. The object just throws stuff at you.
The stuff does not have to be light. It could be something else.

More later. Your two basic premises are sound, solid ground.

I love the "personal universe bubbles". They're a great image of how Newtonian expansion works. Let's add it as a third proposition:

(1) the universe expands relative to the observer
(2) there are multiple observers
(3) the universe expands in a Newtonian manner, that is, x times the distance means x times the speed.

Now composing offline.

Imagine I'm immortal, and my two immortal friends, Alice and Cooper, live in opposite directions from me. We all stay in touch, because our personal universes all overlap each other's centers, and since we're are all immortal, we don't care how long the mail takes even at the speed of light.

Then one day, the cosmic expansion takes Alice and Cooper out of each other's personal universes, even though their bubbles still include my center. Alice is crying at me because Cooper doesn't send her love letters any more, and Cooper is asking me if Alice has been kidnapped or something.

So I relayed their messages to each other. Which should be impossible.

This contradiction shows premise (3) to be false.

Let's define function V(r) as the recessional speed due to cosmic expansion at distance r.

In Newtonian expansion, V(r) = Hr, which leads to that contradiction in causal connections. How can A and C be causally disconnected, and both still causally connected to B? Not.

In Relativistic expansion, our "personal universe bubbles" are all equal in size to the entire infinite universe. Now we can have an infinite number of observers, all observing the entire infinite universe.

Instead of seeing galaxies disappear into the darkness of a "red limit" event horizon, now we see giant supermassive galaxies apparently flattening into a spherical neutronium wall that surrounds us, just this side of what looks like an event horizon that has no "other side". Wherever we may be, we can't get there from here. Like chasing a rainbow, we can't ever get closer to it. Because it's not a thing, it's a mirage.

It's the projection of an infinite universe compressed into a finite virtual space.

FSJ has come up with a way to exceed the speed of light ! It is by relay. From now on we know all we have to do is introduce thousands of relay points and there we have it: near instantaneous travel. And we can stay mortal!
FSJ proposes that by adding two distances, we can reduce the total. Overlap 'observed universes,' and we can have a ball. Sorry, FSJ, to take the mickey, but your posts seem to be straightforward deceptions. If this is not the case, I will apologise upfront. The idea that introducing a relay point somehow either reduces distance or speeds up light is plain er, what? Daft? Alice will cry forever.

We need a Watch Tower or two .
Maybe we can have fun and fire up some good schemes; each of us has our own bubble overlapping everyone else's, then that must explain telepathy. Oh, er, maybe not

The relay works when the "straight" line won't. This points out a contradiction of premises. In this case, I'm saying to NO to the premise that parts of the universe could have a relative motion greater than c. It leads to a logical contradiction — the one you found so amusing.

I don't understand the reference to a Watch Tower.

Oh! the Gondor-Rohan bridge!

Sorry you state the illogical and rather obviously so. It would be a logical contradiction if your logic held up.. It doesn't. Watch Tower and FST (your initials). The relay does not work. And yes, amusing because at first we (I) are taken in forgetting that Alice is not informed instantly but only after her distance is covered. Good fun, but you are not seriously still thinking your statement still works

 

[Fire-Starter James]

I like having some fun, but I'm not trying to pull anything over on anybody. If I'm wrong about this, it's an honest mistake.

An indirect proof works by assuming a new proposition, and then finding a logical contradiction. In this case, the new proposition is V(r)=Hr. Using this new proposition logically, we come to a contradiction. This means the new premise is false.

The contradiction here is that even though Alice and Cooper are not causally connected, they are still both causally connected to me. I can still send and receive messages with both of them. How long the message takes to get there does not matter, only that it gets there. This means "V(r)=Hr" is false.

I find it very annoying to have my posting edited, however insignificant it may be. All I did was mention the name of an organization that publishes a magazine called something like "Watch Tower". Now I feel like I could be in a mine field. Don't worry, moderators, I'll cope with it. Certain names of certain groups might get me edited. Frankly, as a choice between two negatives, I would kinda rather just get deleted, rather than have my words altered. Whatever, it's y'all's website. Just letting you know how I feel, and now I'm done.

I know nothing about a magazine! I mentioned a Watch Tower in reference to your name " Fire-Starter". Forest fires can be contained by observers in watch towers. A joke.
I have not intentionally edited your posts; maybe you are "done" but let's keep the record straight.

What is this: V(r)= Hr? The fact that you can talk to both does not mean that a message sent from Alice or Cooper can be causally connected because you act as a relay station. The massage from one to the other will not get there no matter how often you assert that it would. You could insert any number of relays between the two; it would not make any difference as the total spatial expansion over the distance would be the same (relays or not).

Oh, no! It wasn't you!

I like the forest reference.

V(r) = Hr is the original version of Hubble's Law. Later, gator. Gotta go burn some deadfall to clear the way for the mower.
