April 5, 2017 Reply Bacalhau da Noruega The fermi paradox video has really got my expectations low, regarding our future. We're either struggling against really shitty odds or no odds at all. I don't think humanity will ever make it. April 5, 2017 Reply Jerry LaGrou A space ark for interstellar travel would like only carry women and a sperm bank. Females weigh less, eat less, and breath less. A ship that can carry 700 men and women, could carry 1000 women for the same mass. April 6, 2017 Reply Randall Edwards I just recently found this channel, but I love everything about it. This video was really well done, but I have a thought to add to the discussion. Underwater Arks. You talk about how water is a great source of shielding for radiation. I believe your mars videos even say 1 meter thick water could shield from solar wind issues on mars. How would a gamma ray burst be effected in the same way? Granted anything substantially close enough would vaporize the planet. If the planet did survive the original blast, being on the bottom of the ocean could be a severely beneficial setup. We would be shielded from the dangerous gas (and radiation) present at the surface as well as having multiple energy sources nearby. Geothermal alone could sustain all of our power needs, but we could farm water power in ocean currents and we would have easy access to some biofuels. We would clearly need some way to recycle oxygen, but that would be pretty easy to set up with some underwater gardens. This setup would also protect from all but a direct hit from an asteroid or volcano as well. Aside from interstellar travel, I think it's our best bet.

April 28, 2017 Reply Brown Dwarf If a supernova // gamma burst would destroy the ozone layer, couldn't you have some kind of orbital array of ozone bombs designed to fail and explode as the burst passes and immediately make moves towards repairing the damage? Keep some of that space radiation out of the atmosphere and stuff. I don't know science, but I'm high, so this thought makes sense to me. May 18, 2017 Reply Joseph McGowan "unfortunate chemistry"I love it May 21, 2017 Reply BMan18 Your comment on vulcanism being "not a threat because we're monitoring it" shows you know nothing of what causes vulcanism. It is driven by the interactions of our sun and cosmic rays with the Earth 's electric field. That is pointing to a significant increase in volcanic activity rather soon. May 25, 2017 Reply Ryan P We could seed the galaxy with millions of frozen embryos and hope some advanced civilization far in the future stumbles across a few and brings them to life.

August 24, 2017 Reply Zyngarde Neil Armstrong: Man will spacerock August 27, 2017 Reply Michael Hartman Underground cities or structures would conserve energy and leave more room for crops or nature. This has immediate benefits outside sanctuary, so probably should be started first. Global Extinction is best countered on another planet then off planet craft. The former has the advantage of gravity albeit small and the fact that a planet has more room. August 28, 2017 Reply kk346592 Become a robot, and wear "deal with it" glasses.

November 6, 2017 Reply Pasan Manawadu Maybe the solution to the Fermi Paradox:The only reason we humans are here is because the dinosaurs got destroyed by something, and the small mamals finally got their lucky break. Their lucky break…Baisically non-intelligent reptiles and their alien equivalent are simply much better at survival than flimsy humans because survival of the fittest is a thing. Thus on many, possibly all planets with life, non-intelligent organisms simply beat those with potential for intelligence(the dinosaurs never got smart in their millions of years long reign) so smart organisms never get a chance. We just got lucky coz a huge meteor or a well aimed gamma ray burst wrecked the dinosaurs.

The real issue is preserving the eco system which provides for us.Maybe we need to invent some awesome systems for cleaning up the atmosphere. December 24, 2017 Reply Dejay Rezme No mention of climate change?+2°C cannot be avoided anymore. All the "optimistic" scenarios that already include immense suffering on a global scale assume pulling 5-10 billion of tons of CO2 out of thin air per year, something we don't even do with oil or coal today. So we have to reduce emissions by insane 6% each year, build gigantic carbon sequestration and storage.Right now we KNOW we are heading to non survivable +8°C global climate. The extinction / destruction is already happening. We know about it and we aren't doing anything. It seems only by giving up on democracy and the noise it comes with we could manage to do something.An underground city and manufacturing complex to reach self sufficiency would definitely be easier and more plausible to be done than us fixing climate change or colonizing space. February 7, 2018 Reply Compguy321 What about having an “arc” in orbit able to support a small population of people for many years, then return to earth? March 22, 2018 Reply Jeremy rios My best thought would be to set up a Habitable Space Station around Jupiter. Jupiter would be like a shield…A big one. Jupiter strong magnetic field to block incoming gamma ray burst or any high energy beam. We can adjust our orbit to avoid collisions with meteors and use Jupiter's moons and atmosphere to collect water (Europa), fuel on the top of the atmosphere (Hydrogen and methane), and we can use use centrifugal force to create artifical gravity. Also question, could we titally lock a space station to turn momentum from "falling" from gravity into artifical gravity? In other words could we go as fast around an object in space we can walk on the surface, like on earth, opposite the object we are orbiting?

A bunker may not be able to take a direct or near hit from any kind of asteroid, but if there are enough bunkers, then some of them would survive. We have a seed vault, we need more human vaults and animal vaults. Imagine if we survived but every animal and plant was wiped out. how horrible would it be to live in a world where the only species that are left are us and our food crops. Better than nothing tho. I'm going to get myself a bunker just cus you can get a decent one for 20,000 and they add to your property value haha. Don't rely on the government to protect you.

Space is trying to kill us, the Earth is trying to kill us, and at the moment we are trying to kill us." 🙂 July 25, 2019 Reply Bernhard Maierhofer "Ultimately, our prospects depend on how much warning we have." Oh yeah? I wish that held true with global heating / the climate crisis. Climatologists have been warning about the dire consequences of a runaway greenhouse effect since at least the mid-1960s. Only now the topic is gaining some mass traction and politicians are talking about it – yes, TALKING. It will take too long until they finally enact some of the policies that would have been due for decades. When an impactor appears on our early warning systems, humanity will spend lots of precious time arguing about the reality of the threat until it is ¿almost? too late. You tend to forget it, when you spend time in Space Time's comment section, but people can act pretty dumb, especially when threatened and scared.

It was the ISS along with a swarm of thousands of small spacecraft that functioned in a coordinated fashion called the Cloud Ark.

Sincerely November 22, 2019 Reply fireofenergy Convert some of the asteroids into a one time radiation shield. By the time we're finished building it, we should know exactly when a star will go supernova or gamma burst. In order to convert and move around asteroids, we would already have the energy to move the shield around from some sort of parking orbit to desired location. It would have to be built in very thin layers to prevent its own gravity from deformation. We observe stars all the time, therefore, to better learn their descent from the main sequence, we need very powerful astronomical. Or is it simply impossible to know when a star goes even after decades of continued learning?
