Algebra is a DEFINITE subject that you need to master in order to be successful in chemistry, and some fairly simple calculus isn't required, but will be immensely helpful in certain areas.

Maybe even a 2nd level algebra class

I'd have to agree with coquina and say there are only 2 things that could effect currents like that, one and extemly severe deep ocean fualt near or under where the current passes, or the sun

space ends in all directions

We know what you stand for now tell us why. Why does it have a difenant shape opposed to expansion

The way i look at it is as follows. Before the big bang everything was packed into a infinatly small point call a sigularity(i'm sure you guys know that). Some rupture caused this singularity to explode. With the singularity being so small and so much being pack in, this seneriao would make it naturally unstable, the slightest inbalence could could have cuased it to explode as stated before(sorry for repeating myself ) Now bring a black hole into the subject. A black hole gravitaional pull, pulls serveral million of different things into a similar singularity. Once to much is pack into the singularity it again becomes unstabe and another big bang could occur. How ever two question arise 1. if this happening, why dont see it or 2. has it even happened yet

I'm not trying to say that' date=' but that would follow from this line of thought.

 

I would say this though for sure:

 

You cannot push on a vacuum, and accelerate yourself.

 

I guess we could do it mathematically too, using Newton's second law.

 

You are about to push the vacuum.

 

Your inertial mass is M, and any acceleration you recieve is a.

 

There is a buoy a few meters off to your left, with a blinking light. And no forces are acting on the buoy, and it's at rest relative to you.

 

Here's what you are going to do, you are going to try to kick space, and make yourself move away from the buoy.

 

Let the inertial mass of the space which you kick really equal zero.

 

The force you exert on it, will equal the force it exerts on you, by Newton's third law.

 

The force on it, will be equal to its mass, times the acceleration you give it.

 

Since its inertial mass is zero, the net force you exert on it, is equal to zero.

 

Therefore you have this:

 

[math'] 0 = M a [/math]

 

Where M is your inertial mass, and a is any acceleration you recieve (relative to the buoy) by kicking the vacuum as hard as you can. Your inertial mass is nonzero, so you can divide both sides of the equation above by M, and you get this:

 

[math] 0 = a [/math]

 

So you cannot push off the vacuum, it is nothing. I wasn't trying to say that, but in a sense it follows from what I did say.

I like the way you put it

I think i understand what your saying, "how can nothing(vacuum) be something

What I think I'm getting at is the universe cannot have a shape

If' date=' by the word 'universe' we mean everything with inertial mass, and everything without inertial mass, then the universe cannot have a shape.

 

Saying everything without inertial mass, is a fancy way of referring to the vacuum. 'Space' cannot be spherical, it cannot be cylindrical, it cannot be a cube.

I think i understand what your saying, "how can nothing(vacuum) be something

If you mean do multiple universes exist' date=' we don't know. We could be just one "soap bubble" floating in nothing, or one of many joined together at some event horizon.

 

I don't think anyone here is going to be able to help you in this except offer there own opinions, or places to go for other opinions.

Remotely gaining any knowledge of this is impossible. Good luck?

 

P.S. I have a lot of fiction books dealing in this

You are right, I would like everyone to post any ideas thought or opinoins you might have thank you

Sorry i couldn't do it myself, for some reason or another my computer refused to load the site sorry

Dude that stuff is way complicated but i'd like to understand could you explain please

I got these links to redshift calculators for Crazyghost to use in his or her astronomy club. but something tells me they are not the right thing for Crazyghost. So I will do the problem myself and find out what distance corresponds to z = 2

 

 

 

z = 2 means that in the light from the galaxy the wavelengths are an additional 200 percent longer. that is they are 3X what they started out.

z = 2 means frequencies are one third what they started out.

 

so what DISTANCE does that correspond to?

 

I clicked on ned wright's calculator' date=' put z = 2 into the box

and clicked "general" (same answer as clicking "flat" in this case)

and it says the hubble-law distance is 17.1 billion lightyears.

 

with the siobahn morgan calculator you have to type in 0.27 for omega and 0.73 for lambda, and 71 for hubble parameter H, so it is more work

but you should get the same answer (and it gives other interesting information that ned wright's doesnt)[/quote']

Before we get started I want to say i'm just a 3rd year HS student here to learn. Now onward. I cant remember where i heard this but, i heard a multiverse my exsit. I'd just like to here what everyone thought on that

Do you know why?

 

Rev Prez

As i said before i'm not to knowledgable, but the way i see it is as follows, The big bang is nothing short of an explosion on a massive scale or to scale it down like a grenade. Gernade explodes sending scrap metal in every which direction like the big bang. It not like the scrap metal was instantly put to its final destination. Like the universe the expansion is the result of that explosion(big bang).

There are good people here....just give it a little time....

Bettina

lol Thank you

hay show me your "LOGIC" that space goes on forever and how can it expand if it goes on forever

 

you people act like matter moves somewhere all of a sudden space is created so it can move there that way space is expanding no no no space has to be there for matter to move into

 

SPACE ENDS THAT WAY SPACE HAS A SHAPE

Hey, zazzzoom, are a supporter of the big bang theory

but just to get this out there I am a High School Student in my 3rd year. So my being here was suggested by my Chemistry(who is an astronomy buff and he runs astronomy club, which I belong to) teacher, he tells me I've a great scientific mind. I'm here to learn more then debate

I'd have to say that I believe that the universe is expanding
