In the game you can glide, then go into a dive, and then glide again. Using this technique you can travel long distances. Is that possible in real life?
I will presume you are talking about the real world when you ask, so I will say, using the method that Batman does in the game, by turning his cape into a makeshift and temporary glider, the answer would be NOT YET.
The technology for such a thing may actually exist in the near-future by using materials called memory plastics or shape-memory polymers. Shape memory polymer function by running an electrical charge through a treated material, the material would be able to take and hold a particular shape for a period of time or until the charge is released. The cape could potentially have a SMP ribbing and be fluid-like until a charge was added.
The manufacture of SMPs is relatively expensive and complex, so it isn't something you would see in your average day yet but they have potentially a wide array of possible uses so you can expect them in the robotics, medical, sports and eventually even fashion industries.
The technology is still in its infancy but has the potential for a wide array of applications. Perhaps base jumpers and hang gliders will one day get to experience such a capability, once its been made easier and safer to use.
A series of scientists take the temperature of the idea of Batman using his cape as a glider to reduce his damage from falls and the scientific jury says: Not on your life. Unless Batman gets a whole lot more cape, he will hit the ground at nearly 50 miles an hour. They suggest a jet system (possibly like Batman Beyond) or to stack cardboard boxes to absorb his inertia and soften his landings; which might look a little strange scattered all over Gotham...
No, this isn't possible in real life, at least not for such prolonged and sustained amount of time. Between friction and the 2nd law of thermodynamics, the person gliding would need to take in energy to maintain their gliding.
In the game, there's no thermal currents to provide lift, so Batman is essentially breaking the laws of physics by being able to glide forever. In real life, you'd need the glider to receive boosts of some sort from an external force to maintain perpetual flight.
Humans can't,not yet anyway. But my theory is Batman is secretly a vampire and has powers of energy manipulation; including thermokinesis, the ability to control temperature/make breezy for everyone haha. This also explains why he doesn't splatter at fifty miles per hour; with the help of chi/life force energy sucked from the souls of his criminal-victims lol; he learned how to harness his chi on his travels to India. XD
I could totally believe that.
