The Artisan · Sep 17, 2015

sorry about the size of the images, guys. don't really know what to do about that.

so, there are two types of stars. those that are main sequence and get large, then just burn out and get small, and those that

also start out as main sequence?

become really large, really really large, then explode, then become

either neutron stars or

black holes. our sun is the former.

here's some artist's imagery of "the last perfect day" in about 5 billion years, on the brink of the sun's aging into its red star form.

"The last perfect day", several billion years in the future.

The waters recede and most life is extinguished as the sun starts to swell and its luminosity rises.

The oceans have evaporated and the atmosphere has escaped into space

The sun, now a red giant, fills the sky over a dead planet. As we see in the next section, the red giant will eventually throw off its outer layers and become a white dwarf.

the drawings are by A. Schaller from a Carl Sagan book, Cosmos. pretty neat stuff. If mankind is still around by then, I wonder where we will be...but of course there's tons of other things to worry about our fate before that.

For something that is the potential end of our species, it truly is beautiful.

To think that one day everything we've ever worked for will all be gone.

Randolph Freelander · Sep 17, 2015

My understanding is that the earth will be uninhabitable within the next few hundred million years due to the brightness of the sun, forget about a "last perfect day" 5 billion years from now.

Maybe there will be a last perfect day for Mars.

ldcommando · Sep 17, 2015

But I want it now

DonMigs85 · Sep 17, 2015

maybe we'll have evolved into levitating telekinetic brain sacs by then, and moved off-planet.

Grisby · Sep 17, 2015

Wish I could see it bros.

GraveHorizon · Sep 17, 2015

By then we'll be relaxing on the beaches of Pluto.

botty · Sep 17, 2015

This is just a prediction and not what will actually happen.

lastplayed · Sep 17, 2015

Nice.

Here's HG Wells' Time Traveller looking over one of Earth's last animals swimming in the hot ocean. It's from one of those 70s sci-fi art books.

bjork · Sep 17, 2015

Will our saves still be in the cloud?

Anyway, it would be amazing if mankind can survive that long, but I'd feel bad for anyone that had to live through that chain of events. Makes me glad I'll be way gone by then, heh.

Or will there!

That already happens at death though. As a species we will likely be gone far before the events in the OP happens, and if we were around I doubt the Earth will still look so peaceful and pristine as seen in those renderings.

megarockexe · Sep 17, 2015

Imagine the deserted wasteland the Earth will become by then.
Lots of other significant moments are predicted here too.

neptunes · Sep 17, 2015

All that happens in a day or over many?

Zoned · Sep 17, 2015

I am ready to bet that within 300 years this planet will be fucked.

5 billion years. Crazy just thinking about that.

Zoned said:

Nah. That's nothing in terms of environmental destruction. There will be huge famines before that.

The planet is resilient.

How will you collect your winnings on the bet tho?

ibyea · Sep 17, 2015

We don't need that many years. Around 500 million to a billion years in the future the Earth will be too hot to sustain multicellular life because of the sun's very gradual temperature increase.

Guamu · Sep 17, 2015

Someone just watched Cosmos

Edit: Oh, read the book. I should think before typing.

thekonamicode · Sep 17, 2015

I'm going to build an ark when this starts and then I'm sailing into the cosmos.

If we're still alive as a species at that point we hopefully will have populated other planets.

By then we would have spread through the solar system for sure. We would have built even more amazing things beyond earth.

cdyhybrid · Sep 17, 2015

We'll be extinct or long gone from Earth by then.

Yeah, I remember reading about stuff like this in an Astronomy 101 class I took in college and it was the most depressing topic I studied. Just the idea that the Earth will eventually have no life on it...

Yeah, crazy considering it's more than double the earth's current understood age and that the current oldest fossils of humans are considered to be 200,000 years old.

Carton · Sep 17, 2015

It makes me sad just thinking about, even if it is so (very very) far into the future. I get sentimental over small things, let alone the loss of all the life on earth, never to emerge again.

Megalosaro · Sep 17, 2015

Humans as in homosapiens will undoubtedly have evolved by then. Our ancestors, which may or may not call themselves humans may still be around though.

dankir · Sep 17, 2015

What a day, what a beautiful day!

Yeah, the oceans will have evaporated long before the sun turns into a red giant. Due to the steadily increasing luminosity of the sun, the last of the oceans are likely to evaporate completely in a billion years. Potable water will be gone long before that.

Marche90 · Sep 17, 2015

Images like these makes me melancholic for some reason. Thinking about the future, and a future we won't be able to see...

Cool images, btw.

starsky · Sep 17, 2015

If we can't tackle climate change problem, I'm not optimistic about our chance to survive the next 300 years.

pottuvoi · Sep 17, 2015

Considering that those images try to describe a time when sun has size roughly our current orbit, it seems quite small.
Would expect it to fill most of the sky.

Don't hold back, tell us how you really feel

Kettch · Sep 17, 2015

Considering how far our society has advanced in just a couple hundred years, I'm pretty confident that we'll come up with a solution with another billion to work with, if anyone is still around and still cares about the Earth by that time. The "easiest" way that I can think of would be slowly moving the Earth's orbit out a bit to compensate.

Don't you mean our descendants?

If the sun looked like that/was that big from earth that time traveler would have been dead the instant he appeared. And there would totes be no water there.

I imagine the artist probably knew that and just took artistic liberty like you see in images of the moon being depicted about 20x bigger on the horizon than it really is.

GaimeGuy · Sep 17, 2015

Water? In 5 billion years, the oceans will have been dried up for 4 billion years.

Watched that movie last week because it was available in Netflix.
I honestly don't know what I expected. Especially the first chapter.

Amory · Sep 17, 2015

Assuming we're able to terraform Mars by then, we'd still be dead when this happens, yeah?

There'd have to be some kind of mass effect scenario for us to survive

If you think humans (or whatever you want to call the next few evolution stages for humans) wont make it off earth in 5 billion years you're crazy

We won't be here that long.

It will very likely be a long time before this. I don't give humans a 5 million years let alone 5 billion.
