This is for all those worried about the sun. Sure, the sun has about another 4.5 billion years to live, before becoming a red giant and consuming the inner planets of the solar system, and we are not going to be around when that happens. But what about our children's children's children's.................children. Well, you don't have to worry. You see, LONG before the sun turns into a massive fireball of death, something else will happen. In about 3 billion years (approx) Andromeda Galaxy (the closest one to us, being a mere 200 million light years away) will colide with the milky way, in a giant celestial catastrophe. When this happens, there are two options. Option 1). We will be on the side that Andromeda hits, and we will be fried into oblivion, or option 2). We will be flung out into space...and nobody's quites sure what will become of us.

So those of you worried about the sun flaring up and destroying the Earth, can now be comforted by the thought that we will never have to worry about that happening. Thank You.

Actually that is really funny how you say the sun is going to consume the galaxy.

The is blazing hot ball of gas. What happens when you burn gas? Well it explodes and burns off.

So, the sun is gas right? Gas burns off.....hmmmmmm.

Think about it.

Anyone think that our species will be around in 3 billion years? If not, then how long d'you give us?

You may not know (and if you don't, it'll be my pleasure to tell you) but the Earth has a long history of regular cometary impacts, about every 30-32 million years or so. They inevitably cause mass extinctions, and would have no problem disposing of a weedy naked-ape like us. For example, the dinosaurs 65 million years ago, then another big species killer about 30 million years ago, and also plenty way before that, to let us know that this was not some fluke, but what the scientists call 'an inexorably cycle of doom'. You see, the the solar system drifts 'up' and 'down' in the galactic plane over the aeons, and every 32 million years or so, the neighbourhood gets very crowded. And in those crowded periods, sooner or later something nasty and big gets routed to the Earth.

And guess which 'part' of space we're in at the moment? Yep, you guessed it...

Now it could be today, it could be tomorrow, or it might not be for another couple of million years. But know this. It's coming. And it's got our names written all over it.

Regards,

Caleb Strange.

That's true, but for the first time in history, we can not only detect these things, but also prevent them from colliding with earth.


There are several projects in the works, the one I like the most is launching a bunch of Rock Haulers at it, where they drill up material and chuck it into space.

Because of newton's laws, every rock chucked off the comet will move it a bit..... Throw enough rocks, not only have you cut the size of the thing down, but also propelled it away from us.

Actually this is a common idea people hear. When two galaxies collide its not like a huge explosion. We see pictures of galaxies and they seem so condensed but actually everything is very very very far apart. When galaxies collide very little happens. I doubt our small solar system would be affected, especially because we are on an arm and not near the center. Smile

Now on a similar thought, I read about twenty or thirty years ago that our entire Solar System is hurtling in space smack dab in the direction of the Constelation Hercules. Um, that could be a rather hot experience, if we ever get there.

And what about Orion? Well, I won't go there. (No pun intended)
The difficult must become easy, the easy beautiful and the beautiful magical.

Hmmm...I dunno about that one either. A constilation is a group of stars. They aren't really close together (in fact, the stars can be lightyears BEHIND the one its next to but you cant tell depth)I don't see how a solar system can collide with a group of stars that aren't even close to each other... Can you tell I used to want to be an astronomer? Smile

I wouldn't worry about those things. Some other events will happen way before that on earth that could actually kill all of us.

1-A Giant Volcano (don't know if that is the exact name) situated in YellowStone park, USA (if you guys could tell me the state I'd appreciated it Smile ). It isn't really like a common volcano but it's more of a giant mass of magma under a vast plain. Geologist studied this volcano and search through the different layers of earth and ahses around it and founded the date of the 3 previous explosion. The first one being 1,8 million yers ago...the second one being 1,2 million years ago and the last one being 600,000 years ago. I bet you all figure out that there is 600,000 years that separate each explosion and that the last one was 600,000 years ago...the sientists are saying that the volcano's already late.

Such an explosion of this kind of volcano would create a vaste could of ashes that would surround the complete surface of the earth in a matter of days. This place being near the provinces of Alberta and Manotiba with our most important region for agriculture...all of this will will die...and ourselves too at the same time.

2- A Mega Tsunami (wave of water above 100 meters high) would happen kinda soon. This kind of Tsunami is usually caused by exremely huge fall of rocks (part of mountains etc). The mass of this in contact with water would propulse a wave that is able to travel at many thousands of miles per hour...seriously. They are looking very close to an island these days near the Canari Islands (near Africa) that actually has all the conditions to prove such a natural catastrophe. It is kind of a strange volcano island. It isn't really a reservoir of magma that is inside it but more of some lines climbing up into the volcano.
/¯¯¯¯¯¯¯¯

(it looks like this) /

And in addition of that, there is some water circulating inside it making the rock soft...and by the same way very unstable. The part that will fall from that island is the mass of (if I remember) like half of the Mont everest or maybe even the 3/4 of it. Such a mass would create a wave of about 500 meters high and would hit all of the american east coast (from Florida to New York) in a matter of one hour (which is an average speed of like 2500 or 3000 miles per hour). What is special about those waves is that a tsunami doesn't crush on itself like a common wave. When it is approaching the littoral, the front of the wave is highing up so that it is forming a wall.
|¯¯¯¯__
|___
(a bit like this) /

When this wave is hitting the coast...it doesn't stop. It just take away with him everything that is on his road until it dies. The wave will go as far as 20km from the coast before dying...which is enough to destroy completely a lot of cities (including new york I think).

These two events could happen actually in the next hundred years.

Those are the things that I'm mor worried about...not things that will happen in many millions years.

Where to start....Oh yes. I will NOT be misquoted. I believe I said that the sun would consume the solar system, which is much different from the galaxy. MUCH different. Also the sun will most likely not consume the WHOLE solar system, just up to the asteroid belt. However, in the RARE event that the sun became a supernova (which is most likely NOT going to happen) it would destroy the entire solar system.

There are also other things in the sun besides gas, but not a whole lot. The Universe IS about 90% Hydrogen, 10% helium and under 1% of everything else.

ALSO yes comets do crash into the earth from time to time, but there have only been 5 or 6 mass extinctions in the history of the earth.

Nobody can say whether there will or will not be a giant explosion when two galaxies collide, because I'm pretty sure that not a whole lot of people have seen that happen. (Like maybe, no people, except for liars, who have seen everything).

There IS a supermassive BLACK HOLE in the center of our galaxy, but do not worry, it will not consume us. On the contrary, it is the reason our galaxy exists. In fact, EVERY SINGLE galaxie has a supermassive black hole in the center.

Global Warming and pollution will kill us off LONG before we even see a comet that might.

This post was NOT meant to be flaming in anyway, (rather satirical like Smile and informative like Smile)

And I did NOT have sexual relations with that woman. Um...whoops. Wrong forum.

Seriously, I think this an interesting question. Planning for the long-term is something we rarely seem to do. I'll give you another mischievous example:

A few years ago, the United States Government started a project to mark one of its desert dumps of radioactive material, so that future civilisations (maybe even species) would be able to work out that certain places, so marked, were 'Badlands' and should be avoided.

Think about it. How DO you communicate with future civilisations? Western civilisation won't last forever, and when it and its languages are gone, how will our children's children's children know to keep away from our very dangerous messes?

There were several intriguing answers - surround the site by areas of thorny plants, etc. so they were difficult to get to, or use reflective surfaces, which, in the desert sun, would render such places hot and extremely unpleasant to explore. One much-favoured answer was to use large earth works - ditches and banks etc. - and large stones. (However, this makes me wonder what I'm standing on when I visit similar megalithic sites here in Europe Smile.) However, I believe the chosen solution was to leave such sites as unappealing and nondescript as possible, for obvious reasons/ We're a nosy and curious species.

But maybe, just maybe we've been here before, and deep in a desert somewhere, or a mile beneath the Antarctic ice, something unimaginably bad is lurking. And someone in a tin hat is saying, even now, 'Yes Trevor. This looks like a perfect spot to drill.'

I know this isn't the right forum, but it is the right topic. Before any of that stuff happens, the return of Jesus will come (I believe), and He will take some with him to safety.... find out if your one in the book of John.

I agree with firedice. We don't have long. Either we will kill ourselves or something like an asteroid will kill us. *shrug* We all have to die eventually. don't worry about it.
