Transcript – Lana: Hey Bill Nye. My name is Lana and I have a question about time travel. So recently I have been searching up various information about a so called time traveler named John Titor who claimed that he came from the year 2036 and wrote about all of this in the early 2000’s. So I have a question, can this possibly happen and can time travel actually exist? So thank you.
Bill Nye: Lana, I would say, if I understand this guy’s claims, they are false. Time travel so far is not possible. There is a very reasonable theory that you could build a time machine in which you go faster or close to the speed of light, of course that would kill you because you would be accelerated in these very small radii and at very high speeds and you’d fly apart. But that aside, you can only go back in time to when the machine was built, just a complication. The other thing is when people make these extraordinary claims there’s generally a way to prove them false, to prove them wrong. And this guy took the trouble to only go the 2036, see if he can tell you who one the Super Bowl. And the other big thing I always ask those guys, why isn’t he rich? Couldn’t he have invested in certain stocks? Couldn’t he have seen certain eventualities, outcomes with the stock market, with certain manufactures, be it the Tesla Automobile Corporation, for example, or the Department of Defense in the United States coming up with some famous new invention? Wouldn’t he have invested in certain farmland in the right part of the world to be especially productive? Why? So on and so on. So I really encourage you to look into this guy’s claims. Now, in what we call skepticism or skeptical thought, and also it’s a very popular phrase right now critical thinking, critical thinking skills, we evaluate claims, we look to see if a claim is true or false. You look at a specific thing this guy says that happens in the future and see if it really happens. In general when people make those claims – I’m 60 years old now. I’ve been through a lot of claims of the end of the world. Read Full Transcript Here: http://goo.gl/KtNC32.
