![]() ![]() It’s still not doing her any great favors, but she wouldn’t have died instantly. ![]() However, the shock from entering a 920 mph wind wouldn’t have killed her immediately - a shock wave from a bomb only becomes lethal at about 1500 mph. Felix Baumgartner’s jump from the edge of space got him to clock in at 843 miles per hour before he pulled his parachute, but he was wearing a massive protective suit, specifically designed to keep him safe, and he crossed the sound barrier quite high in the atmosphere, where the air was not very dense. For some context, the fastest recorded wind speeds on Earth are 253 mph (recorded in Tropical Cyclone Olivia, which hit Australia in 1996) and an F5 tornado that hit Oklahoma in 1999, which clocked in at 302 mph. This is 1480 km/h, or 411 m/s, and faster than the speed of sound. So if you put in a difference of one atmosphere into the Ensewiler equation, we get a velocity of 920 miles per hour.ĩ20 mph is kind of a problem. The moon portal is a window between standard air pressure (1 atmosphere, or 2116.216 pounds per square feet) and the moon, which has no atmosphere, and thus no atmospheric pressure at all. P is the pressure difference in pounds per square foot, and the velocity comes out in miles per hour. There’s a handy equation called the Ensewiler formula to convert a pressure difference into a wind speed, which is written out as P= 0.002496 v^2. Even if there wasn’t, Chell could have survived the vacuum of space for about a minute - but we’ll assume that she won’t pass out due to a lack of air, since there’s so much of it nearby.Ĭhell’s main problem is going to be the wind speed. So we’ll assume that she’s perfectly capable of breathing while on the moon. Nor would she need to worry about the average temperature on the moon being -53 C (-63 F), again because she’s surrounded by a vast rushing of room temperature air, and all the wind chill equations I could find indicate that room temperature air (starting at 70F) will only get down to 60F or so. Chell, fortunately, will not need to worry about the air to breathe - she’s only about two feet away from the portal, and there’s lots of air rushing past her. There are a few concerns here firstly, the moon has no air. Chell then spends 30 seconds clinging on to Wheatley until GLaDOS takes over control, bashes Wheatley off the system, and hauls Chell back through to Earth by her wrist with a metal clamp, and the portal is shut down. This portal then sucks pretty much everything that isn’t bolted down out of the room and onto the moon, including Chell, who has the presence of mind to grab onto Wheatley’s handles before she gets pulled through the portal. Chell then puts a portal on the moon, as one does. Chell was meant to have been killed by this blast and wasn’t, but we can safely assume she was not feeling 100% after being bodily flung through a metal grate. Wheatley booby trapped the Stalemate Resolution Button with a bomb, blasting Chell through a metal grill, back into the main chamber and off her feet. Everyone has the above achievement? Good.) (If you have not played this game and are planning to, stop, go play it, and then come back. Let’s review exactly what happens to our protagonist at the end of Portal 2.
