Ok, so I know for short distances this is perfectly possible, but consider the following hypothetical.
You wake up one day on a hard, completely white surface. As you rub your eyes and get your bearings, all you can see is a complete vast whiteness. Everywhere you look, in every direction, looks exactly the same. There is no sky, no floor, no horizon… just whiteness everywhere you look.
A big booming voice tells you that you are in the center of a giant white dome, and if you can walk to the edge, you can make it out alive, but the walk is pretty far. It’s going to take you a couple of days of walking to make it out, so get going!
You are told that you have enough food/water within you to make the journey if you walk briskly, but you don’t have a compass or anything with which to check your bearings. You do not leave any footprints of any kind, and you are not allowed to leave a trail of anything as you travel.
So my factual question is basically this: is it possible for a human to walk in a completely straight line to safety given these constraints? If it is impossible, what tools/tricks could help guarantee your survival?
I’ve heard that when people get lost in the wilderness, they tend to travel around in circles, never really end up getting anywhere, and then they die. Everyone always talks about needing a compass, map, etc to get out of the wilderness alive. I always thought this had to do with panicking and having obstructions that you have to go around, etc. So without any obstructions, and with the reassurance that you could make it out alive given enough time, would you be able to walk out of the Big White Dome? Or is it just inevitable that humans will always veer a little bit to the left or to the right and end up walking in big circles?
Any sort of facts/studies would be greatly appreciated. Personal experiences or situations are always welcome as well. WAGs aren’t bad either of course.
