there are many theories...the expanding and contracting universe is one of them...it is said that after the big bang the next thing is the big crunch...read it in Stephen Hawking's 'A brief history of time'...well, its according to us humans that the ultimate speed is 'c'...and after that, the effect will start to precede the cause blah blah...who the heck has ever checked it coz you cant! travelling at 'c' is IMPOSSIBLE, unless you re in the molecular state....the best theory for the universe is that it is expanding, and ll keep expanding forever, so pretty soon, every galaxy ll be far off from each other, and we ll have a lonely universe!

uhuh, and the earth was flat, the soundbarrier was unbreakable, IC lithography smaller than 0.5µm couldn't be done, etc...

Well, even if we were anywhere near it..say 10000km/s , it wud have been a thought...but all we have achieved is i believe 20km/s(not sure, maybe more)! which is way off 'c'..!..so i guess it IS impossible

Im talking about scientific facts dude...

lol looks like your physics book is quite complete so ANY scientific research may be terminated now

ps: the Big Bang theory isn't the only one, by far so if you pick another, then all those judgements about 'the size' of the universe and it's expansion fall apart

Wanna mess up your head? Think about what's beyond the universe. Pretty scary stuff, when you really get into it.

Try imagining that their is no universe Or void ....... I remember some 10 years back a comet called Schumacher levy hitting Jupiter and some fool told me its heading towards earth (in school) i was so --- scared ...

Naw, not even close. The soonest time to worrry is 2029 when 2004 NM4 makes it closest approach. Odds are only 1 in 300, so I wouldn't be alarmed.

wasn't that Schumacher hitting Villeneuve in fact? 10 years back precisely...

well..ill call it thinking the unthinkable .... but i have a feeling that there s nothing like void, some matter exists everywhere...its beyond human comprehension....the only thing im afraid of are the black holes...thinking about singularity scares the --- out of me!! they re bloody mysterious

it wuz Shoemaker Levy...not schumacher!!

hehehe yeah

It's really an exciting topic, isn't it?
im not saying my physics book is complete, but it's based on scientific research, isn't it? Anyhow, try imagining sitting inside a sphere, and asked to describe it inside out!! same situation here... the discussion is endless. It's like discussing evolution!!!!

It really is Allan, one of my pet subjects. Try wrapping your noggin around some of the concepts described here...

Well, think about this... Few years ago I've joined SETI at Home, downloaded one data pack and after a while hard disc on that PC died without analyzing all of the data. What if in that data pack was a message from a distant civilization? What if next such message will reach radio telescopes on earth in 1000 or 1000.000 years or never again?

this may be true manchild, but there is a little problem there: how would u know if they have the same technology we have, or if they are in the same evoltuion phase. when they say life on other planets, or in other galaxies, they don't really mean humans, or "aliens", but any living form, even a single cell.
Today i was having this discussion with my physics teacher. I followed his speech untill he started talking about relativity, and how mass changes when traveling at the speed of light.. at that point, i crashed and burned
