As for mass effecting speed. Considering our entire method of travel is through wormholes and not actual movement through space (unless you count combat engines) I can't see the mass having much of an effect on speed through travel either. The exception of course being that a larger ship requires a larger wormhole to fit through. So longer calculations perhaps being needed to create a larger one. If by some chance we used a combustion, ion or some other type of engine to push our ships through space, mass would only effect the ship's travel time and stuff while it is within the gravity well of a planet. Once free of it, the mass of the ship would have no effect on it's speed.
Not sure what science you subscribe to JamJul. Last time i checked (and i know i am a dinosaur) that E= mc^2 was still the given formula (thanks to the late and great genius mind Albert Einstein.)
Now with that formula, speed effects mass, mass effects speed. Dont argue with me, I didnt make up the relationship LOL.
I know you probably have all the science fiction movies downloaded to a HDD someplace and what you see about wormholes, mass and stuff; actually seems real to you, but let me tell you this: ITS NOT REAL!! lol
Mass effectively does have something to do with speed in the real universe.
Now, as to volume, that seems to be different, which is being utilised in Sir Emi's formula for total "MASS" of a hangared ship. Formula a bit simplistic and annoying, since a very advanced cargo module with nothing in it can fit inside a hull of a ship incapable of actually physically holding its volume. This is the "doctor who-ism" i keep referring to and does break all the known physical laws of the known universe hehe
However, here we have it, an advanced cargo bay that can hold more "mass" than the mass of the ship is.
How to combat this issue for carrier travel? Simple. Apparently when you stow a cargo hold, no matter how large the capacity of that module is, it only takes up 100m^3 in a cargo bay.(i guess we are just removing all the empty space between atoms out of the equation) So, equip a baby adv cargo bay, say MK IX or X and stuff all your big modules in it for transport. It works until another math model comes along to replace current model.
If by some chance we used a combustion, ion or some other type of engine to push our ships through space, mass would only effect the ship's travel time and stuff while it is within the gravity well of a planet. Once free of it, the mass of the ship would have no effect on it's speed.
Give me a break! You probably shouldnt argue points of view with science without actually knowing anything about math haha
Based on relativity, (i know what u are all thinking, here comes another boring lecture from Dadds) as you approach the speed of light, time dilates, and mass increases (and i think some place that volume you occupies diminishes, depending on the formula you apply). Suddenly, you ARE a gravity well lol. Your mass increases to a point that you are likely to implode into oneself and blink out of existence. Now tell me speed has nothing to do with mass LOL
(oh and on a note, Bon Voyage, Voyager I, the first vessel to ever physically leave the solar system "as far as we know". Only took 36 years to punch through the solar "bubble". Probably not many out there actually remembers the launch. I do)
