As for my own part. Am am more worried about more down to earth hazards. Like to run over in a crosswalk. By an idiot talking in her/his cell phone, or an drunk driver.

 

I think aside from an astroid my biggest fear is germs and virus's. With all the drugs availible were basically fast tracking the evolutions of them.

 

Most people have to fear their attiude running them over.

 

we are protected.
Ronald Ray-gun started with the Star Wars defense and the Doomsday planes thing and when Barry gets the detainees out of Gitmo there will be room for the debris. 2033? There should be enough time..especially when you consider the compression of time with the approaching body masses at the speed of light...
Isn't this Mahmoud's reason for wanting nukes?

Probable Nonsense you say?

 

nothing to worry about

Its 2036 btw. We will know for sure around 2029, giving us time to push it out of the way

This goes to Fermi's Paradox, I tend to favor the thought that any nutjob with a high tech equivalent of a hot plate can distroy the world. For biology it is viruses, for nano tech it is Grey Goo.

Hey, with a little more knowledge, maybe we could take out the universe!

Let's face it, as a species we're not wrapped too tight.

 

My favourite explanation was that this universe is a four dimensional soap-bubble existing within a multi-dimensional space filled with other four dimensional soap-bubbles (Some people say 11 dimensional space, some say over 200) which occasionally bump together spawning a new bubble.

I like to think of that infinity of soap-bubbles is the multiverse and each bubble represents a probability path. I suppose, that would mean that as out universe-bubble expands, it increases the probability that our bubble will collide with another and form a baby universe, possibly siphoning off a tiny portion of our own bubble to form its initial matrix.

 

What is it expanding into?

theoretically...

If I told you, you would turn into a patially eaten pieróg.

 

the theory that makes most sense to me is the cycle one... i dont know what its called, but it suggests the universe is expanding until gravity finally overcomes antimatter's push, and we start collapsing back in ourselves- all the way down to a singular point again. then, BANG another big bang and the whole thing is started over. and over and over and over... "forever".

i like this idea, because almost everything in life is based on a cycle. everything happens over and over. back and forth. ying/yang. from the earth going around the sun right down to molecules vibrating around in tight circles to make up a table desk. everything about life is cycling, i dont see why the universe wouldnt either.

and if that IS all true, we are hardly anything but 1 cylinder in some kid's v8 camero

 

Antimatter's push? The only thing different about antimatter is electrical charge, it has gravity and what not. While not in large quantities, it is the only other form of matter we have in the lab and can play with (albeit very gingerly).

The thing I think is interesting is there could be many forms of stable matter (so called Dark Matter being one). This field is wide open.

 

dark matter is what i was talking about, i thought that stuff is what kept the universe from collapsing in on itself? i know were expanding... but were expanding faster then we should be and i was under the impression its the dark matter forcing things apart?

 

At the moment it is a theory. We can't interact with it, just see secondary effects. Tomorrow another theory might take over.

There was a scifi book I read a long time ago, Newton and the Quasi Apple that explored the idea long before it was common knowledge (over 30 years ago).

 

The dark matter isn't what is pushing us, it is the remaining inertia from the big bang. the dark matter is another form of matter that appears unaffected by gravity. If it was affected by gravity, it would be pulled into our, and other planets atmospheres/gravitational fields.

 

Actually there is some literature that suggests there is something causing the expansion, and it is accelerating.

 

I was recently watching an episode of the Universe where they were showing where a few hundred "terrestrial" landmarks were 50 years ago and where they are now. Connecting the dots and following the lines back to a point of convergence, showed approximately where the big bang initiated. I have heard we are being pulled, and I have heard we are being pushed. But It makes sense to me with the evidence we currently have, not just theory, that we are following the big bangs trajectory and moving from its inertia.

But then again, I don't follow it that deeply to know alot of the current theories and newer revelations.

 

the thing is scientists figured that WAS why we were expanding, it was just leftover from big bang... but once they did the experiments using gravatantiomnal waves or whatever they did (cant remember right now) the result absolutely astonished them. instead of expanding at an ever-slowing rate, we are in fact expanding faster and faster, much faster then we should be if it was just leftover inertia- without any plausible explanation as to why. thats why they figured dark matter is the culprit- and its just like matter but instead of it attracting matter it repels it. like said, it is just a theory.. but what isnt?

 

That sounds good to me. Maybe my ex-girlfriend ate too much dark matter. She is expanding at astonishing rates also.

--seriously now.. You would think if dark matter was a repellent force, it would curve the lasers/light beams we send and receive from space. Star light would be bent all out of whack.

 

Compared to what? Lasers have only been around for 60 years or so, which is purely local in stellar terms. The distances we are talking about start at 1000 light years and greater, we don't have enough time in lab to know anything from direct measurement.

I'll come back with references when I have more time, but the acceleration is pretty firmly established last I heard. The structure is a lot different than originally predicted, there are huge voids out there much like holes in a sponge.

 

Sounds good to me. Im just speculatin'

LMAO! hahaha wow, i can tell she doesn know you post here hahaha

i think that is exactly how they 'see' dark matter- they cant see it but they see the effects it has on things around it... i think anyway, man its been too long since the universe has been on. i miss that show.
