Evidence for Universe Expansion Found

This time I mean it, out for the night.

Why do I feed the attention-trolls?

"The expansion of the universe today is not inflation. You may call it inflation, but inflation is over. It's been over for about ... 13.7 billion years." - vaderetro

How can *you* make that claim?! DeSitter's Inflationary Model shows Inflation continuing until today...and certainly we still see the Universe expanding at ever-faster rates.

Are you going to prohibit yourself from using Inflation Theory to explain our ever-faster universal expansion in all of our future conversations?

Good plan.

DeSitter's Inflationary Model

DeSitter would never have heard of inflation, having died in 1934. He did come up with a model of the expanding universe based on relativity.

Come back when you've read more than one comic book on the subject.

"Come back when you've read more than one comic book on the subject."

Your frame of reference is telling, but doesn't add much to the debate.

[Southack]

"None of what you have done addresses the article linked in post #317, which explains why expansion can occur in local systems and still be below the threshold of detection."

On the contrary, the math in post #381 shows that expansion is *not* below our threshold of detection.

That we don't detection said expansion is a point that you simply can't deal with.

" For that disagreement, I did the math for Doctor Stochastic (he had your same disagreement with RadioAstronomer) in post #381."

Your math was meaningless as it did not account for gravity.

"That math shows conclusively that Inflation Theory hasn't applied itself to our Solar System."

No it doesn't. Of course, everyone else says that the math doesn't apply because Inflation Theory doesn't apply to our Solar System...a point that you'll eventually come to accept.

No one has claimed that inflation does not apply to our solar system. What has been said is that the effects of inflation are less than the effects of gravity within our solar system. Space is expanding within our system.

Nothing in post #381 adresses the article linked in post #317.

Hubble's Constant does not apply to inflation. That's an incredibly naive error in your model there. I don't think you even know where inflation comes into this, when it started and when it ended.

H (Hubble's Constant) is measured across the entire universe. However, our solar system, and yes even an entire galaxy is "gravitationally bound" which basically means there is no expansion going on within these small local areas.

This includes the distance between the Earth and the Sun.

That's incorrect. See post #325...that's the post that kicked off the math in post #381...and 325 was in response to the #317 debate.

[js1138]

Nothing you have posted addresses the article linked in post #317.

[Southack]

See post #611.

You're measuring the raisins, not the pudding.

"You're measuring the raisins, not the pudding."

That's what I was told to measure (see post #325).

By the way, from what location/space did the rasins begin, where are they today, and how do we know where they are today if we don't measure them?

[beezdotcom]

That's what I was told to measure (see post #325).

Not precisely. You measured the separation.

[RadioAstronomer]

Sheesh. Gone for a day and WOW!

[RadioAstronomer]

Interesting.

Just a side note:

Galactic clusters are the largest objects known that the gravitational influence within the cluster overcomes the Hubble Expansion.

[RadioAstronomer]

This is a great discussion. I wish my physics was better tho.

I wish mine was as well!
