Interesting question

[mattisnotonfire]

Well I'll be damned.. I fuckin knew it!!! Somedays are definately longer!

Lol.

Yeah, they always seem to be the days when I am working!

By the way, love your music Ghosty :thumbsup: If you're into electro, I have a mix on my myspace. MySpace.com - Riot:Mode - UK - Electro / Electronica / Dub - www.myspace.com/riotmodeuk

Sorry for hi-jacking the thread! Back to the subject of space and time! :stoned:

Pondering the size of the universe is a pretty mystifying thought. It puts our existance into a different perspective.

Considering the size of the universe, I think it is definatley possible for there to be other life forms somewhere out there. Pondering existance of any life in the universe at all however, is just as mystifying as thinking about the size of the universe. Lets skip all the controversial ideas of creation and move right to things we can feel an accept as facts.

For humans to be comfortable, the temperature generally needs to be between 18 and 28 degrees C. A few degrees below that and it begins to get too cold and above too hot. Water freezes at 0 degree C and it boils at 100 degree C. Now think about this, life on our planet is viable at a temperature window that spans less than 100 degrees C. This is a mere blip on the scale when you consider the temperature of the rest of the universe. The moon alone changes between -233 C at night, to 123 C during the day. The very fact that life would be non existant if the temperature of earth was a miniscule fraction of a difference hotter or colder on the grand scale of things shows just how much of a miracle life is in the first place.

Considering this, I liken the odds of life on another planet to the odds of a person winning the PA and NJ lottery on the same day. First we get lucky with the necessary chemicals required for life on earth, then we get lucky again with the perfect temperature. The odds that life exists somewhere else in the universe are astronomically low. Some people may see "luck" as "intelligent design" so in that case I guess the question would be what are the odds that our intelligent creator decided to do his little experiment somewhere else. My guess is as good as yours on that one.

i believe we are alone in the entire universe i know its so vast beyond conceived minds and all that shit yet i still believe we are alone. Whoever intelligent designer is it is truly genius yet so simple. I wonder if there is infinite tiniest particles beyond the higgs boson just as the infinity space of universe. Anyone wanna discuss about black hole and whats down there i mean its amazing that it has ability to suck the light into it considering its the speed. im sure the time does not exist down in the black hole. anyone wants to mention that we aint alone. you are wasting your time. :thumbsup:

Actually using certain observation techniques scientists have recently been able to come pretty close to calculating to a pretty good degree of accuracy just how big the universe is an how old... I have a couple of really great episode of a series about this question and more from an excellent series that was on the Discovery Channel called The Universe. You can find them on iTunes, it's about $3 per episode but these two are very worth it.

The two episodes in particular im thinking of are "Unexplained Mysteries" (that they actually do go into some logical explination of some of them.. a couple of them being how big and how old the universe is) and "Cosmic Apocalypse" (this also andresses slightly how big the universe is and how it well end.. truly great episodes I have watched each of them a few times). There is also an episode called "The Biggest Things in Space" which I have not watched but I imagine puts things into perspective quite well and may attempt to answer the big question, and is probably just as interesting as the previous two.

I just now remembered the "Dark Matter" episode also adresses this by explaing measurements made in teh actual size and expansion rates by measuring dark matter and the space between astral bodies. Really cool stuff.

I highly reccomend these shows well worth the money if you have a few bucks to spare. They have some quite renowned and respected professors and reseachers adding to the discussions.

The biggest star or single object of mass is a Red Super Giant star. And it would take millions of earths to fill one of them.

I recently watched a program on UK tv on BBC1. It was called 'Do You Know What Time It Is?'

It was based on the theories that you described but mainly focusing on the fact that time is just something that man has made to refer things to. The earth actually rotates on it's axis slower on some days that it does others but has just been averaged out at 24 hours.

Nobody knows how old the earth really is nor what the actual 'time' or age is.

Sorry, this has little to do with what you were discussing, I just find space and time theories facinating. I read 'A Brief History Of Time' when I was just 11 years old.

We all want answers to these facinating questions but unfortunately - they won't be answered in any of our lifetimes.

:stoned:

Lol thats pretty impressive if you started reading Stephen Hawking at 11.

I have to disagree with you on the odds being astronomically low. Think about it for a second. With 1,000,000,000,000,000,000,000 planets in each galaxy. First how many others earths do you think are in our galaxy? Second how about the other billions of them? It's statistically impossible for life not to exist somewhere else.

O and by Earth I mean a planet that can sustain life.

I don't see how we could be alone. The universe is so large that there has to be planets very similar to ours. Not only that, but with it's extremely large size, who's to say that our environment is the only one capable of sustaining life? Just because it works for us, doesn't mean it's the only way.

Thinking about the size of the universe and what else is out there is something that I think about very often. I'm excited to experience the rest of my life just to see what else will happen on earth and what we will discover about the universe. I'm sure there will be a lot of things we could never have imagined were possible.

You do realize that black holes are extremely extremely small and completely invisible to humans right? And that there aren't any close enough to us to make a difference. Scientists suspect that a black hole weighing 3 billion suns is lying at the center of galaxy M87.

Consider this. The probability of life existing somewhere else in the cosmos is next to zero. However, the sample space that we are taking the information from is infinite. This means that although the probability is impossibly small, it still exists because of the infinite nature of the space itself. Now, if a probability exists, that means there must be an equation to solve it.

Put simply, the universe is too big for life NOT to exist.

Pondering which systems and planets can sustain life rather than questioning is there life out there there has to be! is more productive and progressive.
Water is deep-frozen in Mars and life supposedly was prevalent there, so theres 2 outta 8 just in our own tiny solar system.
