Galaxy merging

[wengneuda13]

Which Galaxy is that??

TELL ME BEFORE THE SPILLED MILK GALAXY HAS DRINKED!!

[roric33]

Haha if that dot was out solar system we'd probably be far enough away to watch it without any major side affects!

[FionaTheFox]

Gyr means Gigayears. This is a timelapse of 6,000,000,000 years.

[christaleecarrelli]

the red spot is our system. will be collided

[Hairysteed]

The worst place to be would be close to the galactic center at the time of the collision, 'cause with all the supernovae, radiation and stellar winds our planet would be cooked!

[chopin7tristesse]

Don't worry. long before that the aging Sun will cook off the biosphere of the earth.

[chopin7tristesse]

dark stuff is dark because they don't interact electromagnetically and can't shine. no electric charge. neither creation nor absorption of photons. they interact with matter (photons are a matter) only gravitationally.

[Snorrason]

But they also say that in between 600,000,000 and 3,500,000,000 the sun will get big enough to make our oceans evaporate and the Earth becomes uninhabitable. So we really need to hurry when it's predicted this thing right here will happen around 3,000,000,000.

It wouldn't be that bad of an idea for us to move the mankind to Gliese 581 C. All we need to do is to make our legs stronger so we can keep our weight up.

[BelmondoAlvaro]

better start doing your situps!

[Snorrason]

Right ahead of ya ;)

[Hairysteed]

Terraforming Mars and Europa would be a short term solution for the Sun boiling up, which is supposed to happen at the time of the galactic collision.

[PolarisUSMC]

Luckily, actual functional civilization has only been around about 6000 years. Advances in modern things like electricity and energy have been in the last 100. We have a few billion to work this problem out. I think we'll be fine.

[Hairysteed]

By then evolution (further accelerated by gene technology) would have transformed our species into something quite different

[PolarisUSMC]

Not necessarily. Evolution is not always forward progressing, but instead is completely random. It's in Natural Selection that we see these traits either kept or weeded out. Just look at Homo Floresiensis as a prime example of this.

[Snorrason]

They say the in the process there will be 10% of the galaxies destroyed, if thats true then it's unlikely that our solar system will be destroyed. But when we are talking about the whole mankind we really should invest more in power resources and space shuttles so we can create one big (or many big) space shuttles that can travel on high speed (light speed minimum, crazy I know) so we can escape this place.

[jkbnjkfg]

Surely it wouldn't happen THAT fast? You really didn't think this through, did you?

[QuarksAreStrange]

The clock is ticking. We've got to get out of here!

Obviously, any war should be considered as a waste of time and resources. I mean, watch it again. Does it look like we've got nothing better to do than kill one another? It's the ultimate natural selection of species! Find another galaxy or die.

Think globally, act locally: Tolerate (or even better, love) your fellow man because you know that the challenges ahead are going to be a pain in the ass.

[TaTiska]

It's not for an unimaginably long amount of time so stop griping, firstly, secondly, it'd take YEARS if we left right now before we could reach another star, thirdly, shut up, fool. ;)

[TaTiska]

Wait, I'm wrong, it'd take CENTURIES if we left right now, billions of years before the galaxies collided.

[Snorrason]

Thats all right, centuries is what we have. We even have millenniums. What we don't have is people trying to do something about it. Compared to the power of todays space ships we will have to act fast to make them faster.

I mean, we are all patient people. In 1974 we transmitted the Arecibo message to M13, we expect that the transmitted message will reach  it's destination sometime around the year 25,000.

[Snorrason]

So of course we will be expecting some reaction sometime around 49,000-51,000 (if there is any intelligent life out there). Perhaps the aliens will be our way out of here if we can communicate face-to-face. Most people just scream for help when the see that unusual face of that creature (if it has one), so we might be asking for a fight we might not win (due to our fear).

[dongshire]

thats 21 billion light years away i think

[Masterroxorz]

We are so dead... Well, mankind is...

Erm, the two supermassive black holes of both systems will merge and... We'll probably me sucked in the merging even more massive supermassive black hole. Or we will be, because of gravitational waves or when be crash into some giant star...

[guitarherohater]

no wen these galexies merge everyone is gonna die

if the havent already

[KoopaTroopa44]

wait, wouldn't 2 galaxies colliding be a big enough blast it would creat a black hole?

[FrozenIcePenguin]

doesnt necessarily mean that's Earth, it could be the would solar system

[koomoo]

it is said that when galaxies collide that there would be no explosions because of so much space that is in between everything =]

[intigfx]

yeah, considering our closest neighbour star is 4.2 lightyears away which is 39,735,067,984,836 kilometres, I guess galaxies are made of 99% space

[CryoSporeFan043]

not 99% empty space. It could be dark matter and dark energy which absorb photons (thus making it "dark")

[rpepsy]

how many light years is this ? and is the red dot supposed to be Earth?

[BlackKingX]

I think the red dot is Earth.. That's exactly what I was thinking too.

[Hairysteed]

The Andromeda galaxy is ~2.3 light years away

[PolarisUSMC]

Negative. The closest star to earth is about 4 light years away. The Milky Way itself is about 100,000 light years in diameter. Andromeda is roughly 2.5 million light years away from the Earth, although that is always subject to change.

[Hairysteed]

oops... left out the word "million" :)

[PolarisUSMC]

Heh, fair enough.
