The dream of space travel has been usurped by superficiality.
- Recent survey of 3,000 kids showed that more kids aspire to be a YouTube star than an astronaut.
- Children in the U.S. and U.K. were three times more likely to want to become vloggers than kids in China.
- The survey also indicated that kids in America were less knowledgeable about space travel than their global counterparts.
Trash on earth is pretty bad. But space trash is at a whole other level.
Trash on earth is pretty bad. But space trash is at a whole other level. Imagine how much damage just a single screw can make when it's hurtling right at you at 17,500mph. You can follow Michelle Thaller on Twitter at @mlthaller.
Sending a tiny spaceship to the nearest habitable planet at 20% of the speed of light? No problem, says theoretical physicist Michio Kaku.
Theoretical physicist Michio Kaku doesn't just hope that humanity finds its way onto other planets... he's even picked out the ones we should be moving to — Proxima Centauri B, in the Alpha Centauri triple star system. He's even suggested that the next great space exploration could happen on a spaceship the size of a postage stamp, traveling 20% the speed of light, sent by using high-powered lasers. It sounds like a wild theory, but if anyone's wild theories could come true in the next 100 years, it's probably Michio Kaku. His latest book is The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality, and Our Destiny Beyond Earth.
Watch what it might look like to travel from the sun to Jupiter at the speed of light.
