i see the universe as a pendullum, swinging back and forth, expanding, contracting

But can you prove that that is the case?

Fair enough, but just the one Big Bang is looking very shaky right now ... do we really need any more of them?

Interesting idea, but it may be even more mysterious to them. The more you know, the more you realise how much you don't, and all that...

Ignorance really is bliss, perhaps? Do a Google for Horganism if you want to see real ignorance in action...

By no means is a physics teacher necessarily an expert on the fate of the universe. If they're a high-school teacher, they may have no clue about modern cosmology. I only did after getting my B.S. because I had looked into it myself. That kind of thing is not necessarily covered (or not covered well) in undergrad physics. Even a physics professor may not be up to date with modern cosmology if they're not in a related field.

N.B. I hope you weren't being sarcastic. No smiley, so I assumed not.

if there was no big bang, so is the universe a steady-state?

Soup...when you say "stuff" like his, you really should add "in my opinion" to it...because that's what it is...your opinion.

alright whats your opinion on the big bang

Not so shaky.

The big bang fits all of the evidence well. I didn't really start looking into this until after my B.S. either...

Unless/Until convinving evidence is presented that explains observations better than the BB...I say it's pretty solid.

PlatinumRhymer:
I can understand that some people have an issue with impermanence, and that this might color their preference for theory. However, much in science is uncomfortable. Advances in anatomy were stop and start because it takes quite a stomach, defying many religious practices, and also some emotional remove to be able to dissect a human corpse and record observations accurately.

The point being, a person might prefer the flavor of a theory because of personal preference; but that's not science anymore. Einstein had problems with the universe not being steady-state as well, and later did not much like the conclusions of quantum theory.

Uncertainty and impermanence are two of the problems that we as people have to deal with, and some people are satisfied to shovel dirt over them and whistle. Science is often very much staring into the void; the unknown. It is what I believe was part of H. P. Lovecraft's fear that permeates his stories: that understanding the unknown would reveal some horrible aspect of ourselves as impermanent, unimportant, or arbitrary to the universe. It is something that many people reject not because of science, but because of preference.

i dont know, it seems that we are not sure about the universe, even with these "evidence", its like we dont know whats going on out there, im not completely sold, im still going to hold on to that cyclic universe theory if its not true oh well then i just hope there are other quasi-verses out there (why?, read my sig), or your theory might be true =D>

Other Quasi-verses existing is completly true and completly false as their is currently no way (of what we currently understand) anything can enter or leave our universe.
But if they do exist then technicly anything is, some universes would have no singularitys others would just be singulatirys. But if its possible to form worm holes in our universe it could be possible to create one to another universe, BUT it would have to be to a universe with the same laws of physics as us or atleast very similar ones.
So in different Quasi-verses everything could be identicaly the same as ours but certain religions would be right, certain theorys would be right, dams would be built with water flowing from the shalow part to the deeper part. Hey their could even be one where i dont manage to confuse myself from thinking

Emphasis = grammar correction

That's a good way to start any sentence/post in this forum. Glad to see we're all progressing nicely. :wink:

Better make that a 60-billion pack...
Don't think my liver will hold out that long, but you're welcome to replace me with new converts!

well i dont mean like parallel quasi-verses

who thinks that there are other quasi-verses out there

Hey i got a B in english lit and non of it was based on my spelling

Well we only live once and the universe is doomed how ever you see it

http://antwrp.gsfc.nasa.gov/apod/ap040801.html

This site and its links state that the universe will expand for ever. One little problem i have with it, its based on the zero point field which is so far totaly 100% random so for today tommorow and the day after the universe expands but as soon as it reaches sunday, baby its coming back in again :wink:

This is why i think scientists are completly arrogant, their basing their guess on something which for 1 isnt in the vacuum of space im not even sure it was in a vacuum at all. its next to a huge gravitational body, its using electric conductive substances, its based on 100% random.
all of which in my simple learning seem to be ignorance, who's to say that the laser beam doesnt put a force onto the metal because it does, or theirs electrostatic charge (which could be formed from the laser), the metal could expand slightly (could be due to the laser).

To me seems like someones been smoking something heavy again! but maybe good science is doing that and making stupid irrational guesses... oh is that a green pig flying past my window shouting the universe is a blamonge?

i spell their wrong but get blamonge right... oh the irony

we dont only live once.....
