What is your favorite space fact? 🪐
My favorite space fact is that Arnaldo Tamayo Méndez was the first African American in space, not Guion Bluford.
the fact that the universe is larger than we can imagine.
@sicsinnerindisguise and observe
Do black holes have a solid surface or are they like a gas giant would be a good episode I think
I’m giving 50 years for humans to go extinct
Wow. This talk about interstellar space travel for humans didn’t even address the cosmic radiation problem for humans on a multiyear journey in space. Adding cosmic radiation protection would add tremendous weight to the starship, still a large amount of cosmic radiation would still get through. People would die of radiation poisoning after a couple of years. It also did not address molecules encountered in interstellar space when traveling at 10% to 20% the speed of light. Space is not a perfect vacuum. And then they did not address the amount of food that would be required to be grown to support the astronauts and the amount of space needed for those plants. And then they did not discuss the phycological problems of living in a confined spaceship for years without anyone else to talk to except for the people on the ship which cannot be that many because of the weight problem. What about electronics that start to fail after a few years without the ability for part delivery or repair expertise. And most of these problems are present with a trip to Mars as well.
V-GER
Another random thought, Beetlejuice might not be there anymore dr Tyson 😂
first humanity needs to heal from greed and cruelty!
If you can print people, than beam me up Scotty there seems to be no intelligent life down here.
The scientist looks like a grown up Will Robinson. Try as she might, May was unable to get Neil to break his persona except for one word of jive. Too funny.
What about prestaging food, water and materials at different way points in space all the way to Alpha Centauri?

It’s taken Voyager 50 years to reach the helio pause. It’ll take 75,000 years to reach the nearest star.
