Re: Let’s Talk

this thread really hit it off, huh?

Space:

a couple of you are very confused about space.

The universe is expanding.  well, it is and it isn't.  Light travels in a straight line through space – therefore allowing the exapansion.  many stars are born all the time, therefore contributing to the expansion as well. But there is so far, no 'end' to space… How can it expand if it has nothing to expand into. 

Galaxies are indeed being pulled together by the gravitational force of the supermassive black holes in most of the very large galaxies.  A good example of this is our own galaxy, the Milky Way.  Both The Milky Way and our neighbouring galaxy, Andromeda is heading for collision.  when that happens, the supermassive black holes in the centre of both will unite and the two galaxies will become one.  When this happens, our solar system (if not already dead), will either be obliterated by the force of the impact, or thrown off into space.

Pluto is indeed not a planet.  it is actually an object which originated from the kuiper belt, which is a form of asteroid belt further out in our solar system.  Along with pluto, there is Haumea and Makemake.  The Kuiper belt is made primarily of water, ammonia and methane.

FACT: Almost everything we talk about concerning space is theory, and NOT fact.

Here's something i was thinking about a while ago.

Imagine a vacuum cleaner.  I will now compare the universe to it.

You turn it on.  by doing so, you've started the Big Bang, sucking up dirt, and giving the universe creation.

The bag inside the vacuum cleaner is our universe. 

the vacuum cleaner never turns off. it's always giving more and more. 

poke a hole in the bag and you've got yourself your very own universal black hole.  the dirt is forced through that hole when it gets too close by the gravity/current of the air flow inside the bag. 

if you put this on our own universe, this makes you wonder what a black hole potentially could be.  what if it's just a hole in our bag? 😛

Nothing can escape it because it's being ejected to the outside of our universe.  what's outside of space itself?  this is called an Ultimate Question.  There is no answer as we cannot ever possibly comprehend it.  This is why Space and Time is all theory and no fact.
