![]() ![]() ".One being, the falcon wouldn't be able to withstand that much deceleration in an atmosphere"Īs far as my understanding of fictional theoretical hyperspace physics goes, ships do not really "accelerate" or "decelerate" in and out of hyperspace. However, in A New Hope, Han mentions in reference to hyperspace travel, "Without precise calculations we could fly right through a star", suggesting that either these failsafes don't exist in movie canon, or that he has managed to disable the failsafe on the Falcon (not too hard to believe given how heavily he has modified other aspects of the ship).Īlternatively, we see evidence throughout The Force Awakens that technology has advanced in the three decades since ROTJ, so perhaps the failsafes have gotten more precise.Ī more difficult question is how Han manages to deactivate the hyperdrive manually (we see him pull the lever!) while traveling faster than the speed of light with such precise timing that he ends up meters from the surface. It is supposed to be dangerous and difficult or impossible to override this failsafe, which is why the Interdictor-class Star Destroyers are possible (see ) ![]() It was established in Legends sources (I think the Essential Guide to Vehicles and Vessels was one, but I seem to have lost my copy) that every hyperdrive has a built-in failsafe that cuts it off when too close to a large gravitational body (such as a planet or star). Damaging the ship would have been considered a valid trade off in exchange to getting under the planetary shield. ![]() However if you know what you are doing and have very carefully performed your calculations you can operate between this radius and the damage radius with no ill effects.įor episode VII, the travel to the planet almost certainly was inside the normal safe buffer region and possibly inside the potential damage region. This would be what Nav computers and the safety interlocks on the hyperdrive would be set to work with. Normal hyperspace travel would be outside of this radius. You can travel here if you know what you are doing and would travel into this part of a gravity well would likely only occur in emergencies. Then there is likely to be a larger buffer in which the ship will take damage but is not lethal. You travel through here you die (I.e., the center of a star as referenced by Han in IV). In this case, the fake force is essentially just a measure of the acceleration of the inside of the Millennium Falcon.There are actually likely three different gravity well radii that impact hyperspace travel. It's a way to make an accelerating reference frame behave like a non-accelerating reference frame. Second, Star Wars isn't real life so it doesn't matter (but it's still fun to analyze). First, surely the Millennium Falcon has some type of "inertial damper" that allows people inside the ship to accelerate without dying. What about the g-force? OK, let's be clear about two points here. ![]() This spaceship jumping to hyperspace accelerates a little bit more than that. If you eject yourself from a fighter aircraft, you will have the painful acceleration of something like 60 m/s 2. If you drop an object on the surface of the Earth, it will have an acceleration of 9.8 m/s 2. That puts the Falcon's acceleration at 33,922 meters per second squared. Here you can see that the fitting number in front of the t 2 term should be equal to half the acceleration. ![]()
