If you are ok with gravity that suddenly stops working when you're falling at 500m/s.
I have no idea what you are talking about, I simply said a planet have a gravitational pull, of course there are ranges but some point they are largely irrelevant as at most they would put the object in orbit.
It matters when the pull have detrimental effect on the vehicle trust, escape velocities and such.
Since the gravity works by accelerating objects and speeds being limited mean that objects cannot be accelerated....
Gravity works by pulling, its called a gravity well and what you call "accelerating" is just the effect of a object being attracted by it, since we are talking about spacecraft this is a question of their speed and since you can go in reverse its possible to create a situation were the spacecraft have to provide enough trust to escape the well.
What if you are on:
- The Moon
- Mercury
- Pluto
- any of the fuckload of effectively airless satellites in the remainder of our solar system
- any of the fuckload of effectively airless bodies in the remainder of our galaxy
?
Let me put what is Earth EV, its 11.2 km/s, this mean the game already CAN simulate escape velocity from Earth, so whats you point? Are you talking about crashing into a planet? this is going to depend on the mass of the object and its speed, the minimum impact velocity on Earth is 11 km/s so all of that is well within the 30 Km/s "maximum" speed of ED.
Of all the planetary bodies of the Sol system, only 2 have a EV higher that 30 km/s, thats Jupiter and Saturn ... the Moon? 2.4 Km/s.
Also I am sure you going to throw math at me but I think for the case of smaller planetoids this should be not much of a issue, when it comes to planets with atmosphere the size of Earth this might be a issue, not airless bodies because Mars EV is just 5 Km/ so I am not seeing a issue and that is not even considering that ED cannot go at speeds higher that 30 Km/s.
And that is not even considering structural collapse, they can just make it that if in a planetary body if total speed exceeds x Km/s then the frame starts to take damage and will be destroyed when reaching a total number
