If money and politics were no object...
How wide would it have to be?
How long would it take to build?
How much would it cost?
What would be the dangers or advantages of such a massive superstructure?

sorry about my english I´m not from here but my question is about meteorites .
why do we have to wait for meteorites when our planet is made out of the same matter as the universe itself?
don´t we have our own meteorites at home?
are meteorites made of different material worth the search?

If there are other universes, lets say, an infinite number of universes, then what are the chances that an exact duplicate of this earth exists on one of those universes? Or that another YOU exists somewhere else in space and time?

Will we continue to find deeper meanings that exist beyound Earth? Are we just too dumb right now to see that far?

So the time is slowlier around BH., Lats assume I am hanging around one BH (with a girl and stuff of course), and 2 light years away, another BH with another guy (he is single but trying).

Our time is twice slowlier then without BH around. So I send him a light signal. It will travel 2 years, but for us it would be 1 year.


So for us we exchanged information faster then speed of light??.

just by going by this one "fact", we just MUST be wrong.
We are all in agreement that light can't escape black holes? Ok, that's the fact. since light is effected by gravity, how do the observations we've made on our planet have any merit to the true speed of light? we are in a giant galaxy containing billions of stars like our sun. if the sun's gravitational force effects the earth so much as to whip us around it, then we must be feeling the gravity of the sun but we just don't realize it. all we really feel is the gravity of the earth. we see things fall, not shoot toward the sun. but nevertheless, it's there, and that means that it's also effecting the light we see. the speed of light that we calculate within the gravitational feild of the sun, and the other planets and the rest of the milkyway is thus only relative to this system we are in. if we go to perhaps a region of space where there are no stars, the speed of light could be a lot faster because it's not in a gravit

If you were driving in a straight line in a car and the sun was about to set how fast would you have to be going for the sun not to drop over the horizion.

There are actually two types of nothing.
There is an eternal nothing and a finite nothing.
The universe or anything that goes on in it is an incident,an incident has a beginning and an end.
A slug,an elephant or you has a beginning and an end.
your beginning is,sort of obvious,it came from a potential.
Your end is the end of an incident it will never happen again,it is eternal.
The universe had a beginning and it will end and never happen again,it will enter a state of eternal nothing.
Before the universe began,there was nothing,but there had to be a potential and the potential had to be finite. If it was not finite it could not have changed.
Some way a space-time pulse was initiated a fraction of a second after time zero.
This space-time pulse matured and produced us and the universe that we experience to-day.

what do you guys think of this?

That the plane of existance, time, movement , space, all had a beginning, (from nothingness) and will eventually have an end, turn back into nothingness.. and stay nothingness... forever

your thoughts?

Think about it, how could something, anything have "no beginning" and have ALWAYS been there?

Also I don't think space can be infinite, how could anything be infinite? Everything has to end somewhere, just because humans will never be able to reach the expanding distances of space doesn't mean there's no end? As we speak space is expanding, but i'm saying, what if a ship was created that was so fast, it could outpace the expanison of space, and could ultimatley reach it's outer limits? What do you think would be there? "Nothingness", does it really exsist?

Something, so powerful and unbelivable had to of created this, something that breaks the laws of science, and I belive that is God.

Think about it, how could the fact that we're living , our consioness, our exsistance, actually be happening, was there a time "life" as we know it was "nothingness"?

Also has it ever occured to you that other forms of life could or could've exsisted long long before we can even imagine? and that the cycle is just continuing over and over? Scary to think about
