First, it was black holes were keeping the universe from flying apart. Lately, it is an invisible dark matter. Now gravity must be leaking. I can’t believe this stupidity to justify a flawed theory of an expanding universe. 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. The universe is not expanding, light (and other radiate energy) shift to lower frequencies with time until they blend with the background radiation (do photons have a half-life of 12 billion years?). 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. Then there is nothing for 14 billion years from sources that we cannot even define as proto galaxies. 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). 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?
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.

Excellent point.

There is no way we can know one way or the other.

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.
Help me out here...
Is the universe expanding?
Is the "expansion" accelerating?
Whaddya mean..."slowing them down."?
