From the Ted Talk by Ron Shaneyfelt: Is space trying to kill us?

Unscramble the Blue Letters

There are still lots of things about space that we may never be able to answer, like is time travel possible? Or are aliens living somewhere else in the Milky Way? But there is one thing I believe about space: Space is trying to kill me. Space isn't out to get me personally. It's also trying to kill you and everybody else. Think about it. scape doesn't naturally have what we need to survive when we travel there: no air, it's too hot or too cold, no ozone to protect us from those nasty UV rays, either. This all sdouns bad, but what can space really do to me if I stay on Earth? What we need to understand is that objects in space can cause people to think their days are numbered, even when there are events on Earth that can hurt or kill us before something from space does. So, what are the odds that one of these objects will really affcet Earth and you and me in our lifetime? Well, we can take what we know about the universe to try and frigue that out. You might have heard seotirs about asteroids hitting the eatrh. That would be pretty bad. Scientists think atsrioeds might have killed off most of the dinosaurs. Sounds like something we should worry about, right? Well, astronomers can now watch asteroids in space and see them coming using complex computer mleods to predict the deadly rock's path. For a while, the reported odds that asteroid Apophis would stkrie Earth in 2036 were once 1 in 625. But, after updating their data, astronomers now say the chances are extremely low. Okay, what about the sun? Hollywood movies like to pick on our sun by showing Earth destroyed by sloar flares or the sun dying out, which would cause Earth to freeze. atrmosnoers predict our sun contains enough gas to make energy for another 3 to 5 billion years. So, in 3 to 5 biollin years, if people still exist on Earth, they'll have to deal with that. But today, well, we're safe. Sometimes the sun does sohot flares at Earth, but the magnetic fields surrounding our planet bcokls most of that radiation. The radiation that does get through creates things like the Aurora Borealis. Gigantic solar flares can mess with our satellites and electrical equipment, but the chances of it kllniig you are pretty slim. Okay, what about that suvserimaspe black hole in the middle of our galaxy? What happens to Earth, and us, when it pulls us in? After all, it is supermassive. Nope, not going to heppan. That's one big ocjbet that can't bother us. How can we be so sure? Our solar system is on the edge of the Milky Way while the nsraeet supermassive baclk hole is about 26,000 lgiht years from Earth. That means we aren't on that black hole's menu. So, you still think space otjbces are trying to kill you even after what I've told you so far? I think I've even convinced myself that odds are really good that space and the objects up there won't kill me after all. But I'll probably keep looking up just to make sure nothing is headed my way.
