Such implications are not on the mind of scientists when they forumlate theories. It just isn't relevant.Loki Mythos said:I have always had a problem with the big bang. First off, it just smacks of GOD.
The history shows that the reality is quite the opposite. For most of the existence of actual science about the origin of the universe, it was believed to be static. The Big Bang is the inevitable result of the discovery that it isn't.It sometimes seems to me that cosmology, in general, goes out of its way to prove that the universe was created and that their was a beginning to time.
Our brains are not hardwired with knowledge about the universe, only with the ability to process information. So the proper way to go about learning about what's known in science things is by learning the evidence and what the evidence implies - not by just accepting your own preconceptions.I have trouble with this because I can not conceive of a beginning or end of time, it seems to go against the logic that is somehow hardwired into my brain.(please, no if a tree fell arguments)
That last sentence implies there is an "outside". There isn't.The same with the size of the universe. I just can't see it as finite. A finite amount of matter outside which, nothing exists.
Sorry, that doesn't make any sense to me. It doesn't seem to describe what we actually see.Yes, I understand that almost all of the galaxies that we can see are red shifted. But I haven't seen anyone argue that an infinite universal sea, sprinkled with matter is simply undulating, just like any large ocean. The idea of Conservation of energy(energy can not be created or destroyed), to me, argues for an infinite undulating universe and against the idea of a big bang.(if anyone knows of such an argument, please direct me to it)
It doesn't matter how long we've been observing, what matters is that we've made millions of observations. It wouldn't be possible for all those observed galaxies (and the cmb) to switch to blue shift after a while. You did just say "conservation of energy", right?It also seems to me that we haven't really been observing for very long. I mean how long has it been since Edwin Hubble and William Huggins? A blink of an eye. Do red shifted galaxy's stay red shifted at the same frequency over time? How much will they change in a millennium?
We've had this argument already. The fact that on the small scale, the universe isn't a silk sheet doesn't mean it can't be described as isotropic. The word is just a single-word description. It alone doesn't tell you what is really meant by its use. Ie, is the universe's "grainyness" 1 part in a thousand? A million? A billion?Just the fact that we can see a few blue shifted galaxies and are in fact on a collision course with one seems to indicate that we are not in a isotropic or finite expanding universe.
Red-shift data tells us that nowhere within our horizon is there a place where anyone would see a contracting universe.Perhaps only the part that we can see, is expanding, at this time. If we were in an expanding part of the universe, would we be able to observe a distant contracting part moving away from us in an infinite and eternally undulating universe?
I don't know if "arrogant" is the right word, but it certainly would be foolish - which is why people don't make that assumption!In view of that statement, it seems to me that we are arrogant to assume that there is no matter beyond what we can see with our limited means of observation.
