yes but it only takes maybe 200kbit or so to have one node on mars synced in realtime to earth, so a single 100mbit connection would probably let them share the chain

i'm pretty sure nikola tesla was scratching at the surface of how to do gravity nullification

i'm also pretty sure that gravity is an effect created by electrons in a quantum state we don't understand yet, so what i'm saying is essentially gravity nullification is about creating a field around an object that deflects this kind of particle, without that resistance to motion created by gravity you have the ability to travel a lot faster, this doesn't mean you can travel faster than light (that would be teleportation), but if you could get to mars in a day that would be sufficient i think
