sweet i found the description of infinty, from this book my ex girlfriends dad has...about space and time etc...

ok so from what i remember, this is what it says.(to my recollection)

a line cannot be infinite, a line always has a point A to point B...distances between said points just vary.
but if you take that same line...and you bend it so that it forms a circle where point A and point B connect, then this "line" actually has no end. to tread on the circle would give you no destination. its not that you literally "go in circles", its just that it keeps going, a circle has NO end.

i think thats the best description of infinity that we can imagine.

That idea has never sat well with me, because when you have a dot traveling along that line, it'll eventually return to the same spot that it was before (I'm not implying that it'll stop, but the fact is that it still touches the area that it had already traveled). Thus, to me, that suggests a "limit", because the dot is confined to a discrete area.

With a line going off into the distance, at least the dot following it will never re-trace its path, ever.

If the universe has an age, than what was present before it? And did that have an age?

You know, while typing my answer up to your questions (which I've now discarded in light of what I'm about to say), I thought of something that I hadn't thought of before...

The universe has to have an age, since time is one of its parallels, correct? If so, then wouldn't that cause the "cyclic" universe theory to render itself moot, since that would imply that the universe has no discrete age (it would be infinitely-aged), which is contradictory to the measurement of time itself. Unless, the cyclic universe theory also adds that's there's a momentary lapse (during that small part where the physics models fall apart) where time stops and restarts itself, or unless my rambling is a bunch of crazy BS.

Wait a minute, you're saying that the big bang created everything? Doesn't that go against the theory that "Matter can neither be created nor destroyed"?

As Famine said, at moment of the Big Bang, space-time was created. That means physics never existed before the Big Bang, as there was nothing for them/it to exist in.

This is just the butterfly effect, if a butterfly flaps its wings in brazil there's a tidal wave in japan or something. The only thing wrong with you theory is a tidal wave in japan isnt going to matter to anyone except people on earth. Because any other intelligent life is to far away. what Im saying is we only effect stuff on our earth, which in away can be regarded as a universe of sorts. What I mean is for anythign to have an effect on the universe it would have to be a comparable size to a human and the earth. Also one person cannot bring change (contrary to what many believe) they can merely bring about change on people of equal or lesser value as themselves, if you have enough people you form a council but everyone on the council is equal (theoretically). That council however, has the power to influence other councils and then the group of councils form a city and so on. So I guess you are right but you didnt define a key point. 1 object has no control over anything of greater value.

 

[F.Zamataki]

yes, but i also stated that eventually over time, the human race will creat an effect on the planet, that might affect the solar system and so on and so forth.......but our suns gonna blow up pretty soon so who cares....ive gotten my fill over this topic

 

[Crayola]

Yeh, I noe. I understood you, Im just sorta paraphrasing your idea and mixing it with my own.

 

[Danoff]

...planet maybe. solar system? we can't right now. sun's not going to blow up any time soon.

 

[milefile]

Why are we here?

Hmm.

Wouldn't that be for each individual to choose and decide for himself?

Unless you are a preacher, a type who insists there is one reason why we are all here that we all must embrace. Then individuals choosing for themselves is no good and we all need people telling us why we are here.

Take into account the gravitational constant and the fact that when matter becomes extremely condensed it heats up alot, then you can understand that the "Big Bang," if we're following that theory is part of a cycle that repeats itself every few billion years. The explosion sends the matter flying off in all directions and based on gravity it condenses into stars, planets, etc. Now, as you probably know, everything in the universe is moving against the force of gravity; that is, it's all moving away from each other. Gravity, naturally, will slow this process. In a few billion years, the universe will be static, and everything will be stopped dead in place relative to itself. Give it a few more billions of years and the universe will start to collapse in on itself again. Now, if all the matter in the universe were condensed into one place, you can imagine that there'd be a pretty big explosion in a little while. So, that is what the big bang was; all the material in the universe condensed into an area the size of a few galaxies going super-duper-nova. Do you follow me?

well on this i have read about some other number (lambda) that was recently discovered (1998 i think) which indicates a kind of anti-gravity. while gravity will slow stuff down adn eventually pull it back lambda will repel that and according to scientists in a really really long time will cause the ever increasing expansion of the universe if i interpreted that correctly.

On this some scientists discovered that light actually is matter as they observed its passage around a planet where the light was bent ever so slightly from the gravitational effects of the planet which means it has to be some sort of matter with a weight that can be affected by gravity.

 

[Danoff]

bent ever so slightly from the gravitational effects of the planet which means it has to be some sort of matter with a weight that can be affected by gravity.

This is the well known phenomenon that is observed at the event horizon of a black hole.

i was just trying to demonstrate that light is matter since he was wondering how they could freeze light.

I was just trying to help you do that.

Light is made of matter.

Incorrect. Light is made of photons. Photons are "packets" of energy. Energy is not matter.

how is light bent by gravitational pull then?

 

[Mike Rotch]

Gravity bends the space-time fabric that light passes through. It doesnt actually bend light. The diagram below shows this:

Note: The depression in the second diagram is a gravitational source, such as a sun, large planet..

In the first diagram: Light travelling in straight line in space-time not bent by gravity; it continues along its path.

In the second diagram: Light travelling in a straight line, and then passing through a region bent by gravity, has its path altered by the curvature of space-time.

Cool. Gravity does not act on light itself but rather the environment light exists in. That's in interesting distinction. Thanks Mike.

RIGHT! I've heard that before, but I always forget about that funcky space-time warping. Thanks for clearing that up.

I've also heard that in some experiments light will behave as though it is not matter, in others it will behave as though it is.

 

[gt4]

thanks for showing that. good to learn when your wrong.

You just KNEW I was going to mention something about this, didn't you?

Part of Einstein's derivation of his famous, and misquoted, equation e=(delta)mc², assumes that energy and matter are interchangeable at some level. Energy and matter are not completely independant of each other...

But this is just complicating things more...

(nice diagrams, by the way)

 

[gt4]

where did you get those diagrams from?

 

[Mike Rotch]

, I drew them.....And google rules of course

Sorry, yeh they are photons, the real questions is are photons matter?
I'd say yes, because light can be slowed down when it passes through objects of different density.

 

[Sage]

Well, the problem is that sometimes photons exhibit matter-like characteristics, and sometimes wave/energy-like characteristics (wave/particle duality). I've personally toyed with the idea that it should be considered its own kind of thing.

I just realized the title of this thread has no connection with photons.

 

[Street Fighter]

Your theory is flawed, you text color stealing bastard.

 

[F.Zamataki]

flawed huh?? nahh..its just some thought i had one night while i was on e, i wrote that whole thing while on drugs....kinda makes sence..anyways
i didnt steal nothing....comon man, pink unite...were the only 2 cool enough ppl on this site to post in pink

Everything that lives on this planet has the one soul purpose of passing on it's genes to the next generation. That is the root of the history, life and evolution of the planet, now when u really think about it thats all whats lifes about. For example u take to smallest life forms (viruses bacteria etc...) they live on 2 things, eat and multiply. Its only when complex lifeforms like humans that have created super complex social structures throughtout evolution we have broken through natures restraints begining to find secondary purposes in life. I don't need to go on about the purposes but such things makes us as a people to leave more than a natural mark on the world through our children, but to continue leaving our cultural evidence through books scripters and other forms of data.

In conclusion its all about choosing that second purpose in life
