Speaking from personal experience, I take it? ;^)>
The moon took lessons from Douglas Adams.
I have a simple explanation that, on the surface, explains everytthing without dark matter, leaking gravity, etc.
Consider that the light from the nearest objects being used for red-shift data left their sources long before the first red-shift measurments were made. Now, suppose that the expansion of the universe has already stopped, and the collapse has begun. Therefore, we are accelerating and receding from objects that appear to be spreading outward because, at the time the light left them, they still were receding from one another. The farther away the objects are, the faster they would seem to be moving away from us, since it would take longer for evidence of their slowing down to reach us. The nearer objects seem to be moving away more slowly because we see evidence of their deceleration sooner.
It's simple, it follows the laws, and it doesn't depend on any hidden matter or leaking gravity.
I am not an astronomer, but I did stay at a Holiday Inn Suites last night, so fire at wiil!!
Scientists have known since the 1920s that the universe is expanding.
Scientists have known no such thing. Scientists know that the universe appears to be expanding, not that it actually is.
As our deep space vehicles have shown, there is some unknown phenomenon that is slowing them down. Isn’t obvious that the same degradation happens to light. Older the light, farther it will have slowed and shifted toward the red.
Excellent point.
The universe is supposed to be 15 billion years old yet we can see well-defined galaxies 12 billions years old in any direction we look.
Excellent point.
How long does it take for a galaxy to form? Probably longer than 3 billion years for that much matter to gather (unless the gravity constant had changed in those early years).
There is no way we can know one way or the other.
Is Hubble such an icon in the astronomy community that the red shift can never be questioned even when new empirical evidence gives another explanation?
Yes, it is dogma. This has happened again and again throughout history. Like the guy a hundred years ago who advised some up and coming physicist to abandon the field because everything that could be known had already been discovered and it merely a matter of wrapping up the details. Then Einstein came along to wrap up the details and blew the whole field apart.
Nobody ever wants to admit to the Mystery. Nice post.
It's not really leaking into another parallel world. It's just having its effect in more than the three spatial dimensions. Since the extra spatial dimensions are coiled up tight, the gravity effect is more or less lost there in a dimension we cannot interact with.
Dr. Venkman may have found a new, corporate direction:
Universal Plumbing
But will the EPA Administrator allow him to turn gravity OFF while he changes valves & pipe connections?
Time will tell...film at eleven.
My perpetual motion machine uses duct tape -- lots of it -- to minimize the leakage. Very soon now, I shall astound the world!
Interesting idea. We once tried after many drinks to try to hit the Apollo mirrors with a laser (yes more powerful than a pointer). The results of the test are in dispute since we passed out before verification. Damn tequila. I still think we hit it and got a return.
Anti-gravity?
What if the universe were actually like the inside of sphere. Galaxies appear to be flying away from each other, but in reality all converge again on the far side of the sphere?
Dark matter is sucking the funds out of my bank account.
If that was the case , you would think that the close galaxies like Sagittarius ( at just 75,000 light years )would show some evidence of that. Presumably, if the expansion ended, the collapse would effect all bodies within the universe in a similar fashon, us and our nearby galatic neighbors included. We should need to see things beyond the redshift to know what direction things are heading in.
BTTT
'Cause it's going around in circles.
Me too, but I thought it was my ex.
I understand that. However, gravity is spreading out into the ten or eleven dimensions currently postulated by physicists (I've seen as many as 64 proposed, but most stick to the lower numbers). If the effects of gravity were concentrated in the first four, or conversely pushed more heavily into the other seven dimensions (reducing its presence in the first four), one wonders what might be possible.
Help me out here...
Is the universe expanding?
Is the "expansion" accelerating?
Whaddya mean..."slowing them down."?
"Since the extra spatial dimensions are coiled up tight, the gravity effect is more or less lost there in a dimension wecannot[don't know how to] interact with."
How powerful was your laser? (and more to the point, was it green?)
