Questions that no one will ever know the answers to
Sun May 15, 2005 3:05 am
I copied and pasted this from another forum I go to. The thread was made by me of course. Anyway, hope you don't mind.
This idea was inspired by the thread of mine "The little things are sometimes the spookiest". Don't you think about things that no one, at least not in our time, will know the answer to? Time to post those questions here so that we can talk about them and offer our own thoughts and suggestions as to what the answers could be. Because there is always an answer to everything. It's just that most things aren't very easy to even understand.
Nothing trivial here please. Take a look at my questions and it will give you some idea as to what kinds of things I mean.
Q1: Is space infinite?
Q2: What would happen if a person were to go back in time and change something, or make something happen that wasn't there in the future?
Anyway, my thoughts on the above:
When I think about it, how can space be infinite? I see space as a mass, an actual thing, and to me, no mass can expand and expand for eternity. It just doesn't seem possible. Everything has to stop somewhere. However, I looked on a website and it said that if you went into space from a starting point, walked in a straight line, you would eventually end up back at the starting point. So what is that suggesting? That space itself is spherical just like the planets?
And my thoughts on the second question:
On Doctor Who, Rose Tyler, the Doctors assistant, saved her father from dying when she went back in time. That would change things dramatically wouldn't it? The whole entire world would be different just because one extra person was in the future that wasn't there before. How would that work? People had already lived the future their way, now it would be different. It's like they would live two lives. The life before the alteration in time and the life after the alteration. Say we went back in time now, all of us, the whole world, and a meteor struck when it hadn't struck before we went back and we all died. What would happen to our future selves? We'd already lived past the era we traveled back to but now that the meteor has struck and we're all dead, what would happen?

Well.. I guess if you want to take what that person said about ending back up in the spot you started in. Then I guess they are saying that space is spherical like a planet.
And if it is spherical...does that mean there are other 'planet' spaces with their own worlds and such floating in their own spaces.. and etc etc?
Boggles the mind doesn't it

And as for the time travel thing. I don't think if someone changed one small thing.. it would change very much.
I'm sure some things would change, but I doubt it would be some cataclysmic thing.
Also.. if everyone were to go back in time... and we were to all die from a meteor hitting the earth. Would it matter what had happened in the future? Because well.. we'd all be dead so it wouldn't really matter much. No one would be around to see if something happened.

If space is expanding, what's outside space?

Well, supposedly if all of space was our universe, the popular theory is that the universe is basically shaped like a giant globe. So, there are really only two ways for the universe to change size.
One is for it to expand forever, and gradually have the galaxies dissapear into darkness. The other is that the universe has already expanding to its maximum size, and now it's slowly contracting. This, the scientists say, will lead to another big bang.

The Big Crunch? Where all the planets collide and all slowly devour into the sun?

I think all of our "space" is on a little speck of dust on a sock in some college boy's messy dorm room. Yup.
And if the past was changed, the person who changed it would suddenly explode I'd imagine. That or we'd all be sucked down some magical black hole. Who knows? I can spend hours thinking about time travel and what it could possibly do.

Questions like that make me twitch. Kind of fun how our undestanding of what surrounds us is rather limited looking at it from one point of view.

Yes, space is expanding in size constantly and everyday everthing doubles in size.

Well yeah, our own solar system's demise will probably come before all the galaxies are compacted into a little ball half a teaspoon wide.

But just how much more room do we have to expand? If space is endless...But, how can something be endless? There has to be some sort of end to it, right?
Argh, this stuff is confusing. I feel so **tiny**.

What is the meaning of life? (Actually, we already know this. 42, duh.)
Why do stupid people not know they're stupid?
Why don't guys understand girls?
Why don't girls understand guys?
Why don't some people acknowledge that I'm the Queen of the Universe?

The time travel thing would create time "Pockets" in my opinion. By going through time, you create an 'Alternate Timeline' devoid of the one you originated from.
And going through to the future can 'change the past' as well. I'll let you think about that statement for a bit.

Well surely that implies that they double their mass. Where does this matter come from?

Sadly, the contents of my wallet do not appear to follow this phenomenon.

Perhaps they do, but since everything else also increases, the expansion of the wallet items are exalled out by the counter-expansion of everything else
