How Far Can We Go? Limits of Humanity (Old Version – Watch the New One)

Is there a border we will never cross? Are there places we will never be able to reach, no matter what? It turns out there are. Far, far more than you might have thought…

What is the mistake? In a nutshell: It is not PHYSICALLY impossible to leave the Local Group as we said in this version. It is just extremely unlikely that we’ll ever do it, even for the standards of our videos.
BUT: If you have a lot of time and a fast spaceship you can still fly to a limited amount of galaxies – these galaxies will eventually get out of reach forever but until then, they are within reach. Although every second some of them escape us forever.

Ok, if this is so why did we keep the video up and not purge it when we deleted our addiction and refugee crisis videos? Well, it has to do with the nature and severity of the mistake: This mistake was much more straight forward then with the other two videos, so we did talk to a few astrophysicists to ask them what they thought and if we should take down the video. Their feedback was pretty clear, they thought it was still fine as the universe expansion things explained in the video are correct and they didn’t consider the local group thing as too major. This was actually a case of “good enough”.

Also, back when this original upload happened, Kurzgesagt was operating at pretty tight margins and just redoing a video was not easy for us. Back then the team was small and we were fighting to put new videos out. So we just swallowed the bitter pill and kept the video around.

But the video still bothered us, as far as we know this was the biggest unfixed mistake on the channel. Super frustrating, especially because the core idea of the video is so fascinating. The limit of our species. The actual limit. So yeah, we finally remade the video, sorry for taking this long, life got in the way.

The original video will stay up, you can compare the two if you want to see how far we have come in a few years in terms of production quality. All in all, we could only grow the channel and work on getting better because of direct support from you guys. So thank you for that. – Philipp

You guys are incredible in your presentation. Something for me to aspire to!

[christianforehand]

I love how Kurzgesagt always ends on a happy note. Like its all depressing and he's like "but, it's not really that big of a deal" :)

[prathameshraje]

He first depresses us and then calms us down. It's his speciality

[poe_slaw]

"but it becomes even more depressing"
my favorite

[Ophaganestopolis]

Since science as we know it is only some centuries old, I like to think that with so much time ahead of us, we could eventually find a solution right now unimaginable.

You have billions of years to like this before the milkdromedians take over the comment section...

Just set your shipping address to the next local group and Amazon Prime will get the order shipped for free within two days.

I want this guy to walk around behind me narrating my life with the acclaimed optimistic nihilism.

[HOUNGOUNGAGNE]

The narrator's voice just makes my mind going blank and focusing 200% more on the video. Love it! :D

[anakarada]

For some very irrational reason I felt claustrophobic when he said we would never be able to leave the local group

6:33
We can't go out of our universe
We can't go out of our observable universe
We can't go out of over Galaxy cluster
We can't go out of our Galaxy
We can't go out of our solar system
We can barely go to our one moon
And now we and even get outta our house
And I'm not done

I can't get out of my bed

[vvv-eqkq]

So there is social distancing even between galaxies

[leonardowangcl]

who's here after Kurzgesagt remade this already epic series :)

[randrianaivotantely]

This sounds like an epic fantasy.
'There was once a time when the galaxies shared light between them,
But a day came when Dark Energy tore them apart.
In the destruction that followed, two star crossed lovers, Milky Way and Andromeda, gave birth to a single child, Milkdromeda.
That galaxy only knew stories about the rest of the universe, as Dark Energy divided them forever.
But in that pocket of light, life grew.'

[RedRiotRoss]

The adventure time horse captivates me on a level only the entire universe could dream to be

[hugok]

"Is there a border we will never cross"
North Korean citizens: Yes

[omercan]

Imagine if our "universe" is something like the local group and everything else is far away
