why are we still use propulsion, its almost 100 years tech are we fucking retarded?
No, but you clearly are.
>>13264882ok smart boi
>>13264871Propose a better solution or keep your gimp mouth shut
>>13264924magnetic propulsion system
>>13264929That's still throwing shit out the back, just a different energy source
>>13264952right, but at least its a clean and more effective energy, the next step should be kinetic gravity engine
>>13264966>kinetic gravity engineyou mean like a giant trebuchet?
>>13264966Probes are already using gravity assists and it's slow as fuck but efficient. We should already have cis-lunar nuclear tugs and interplanetary haulers because it's 60-70's tech but waah n-word scary.
>>13264871why are we still use wheel, its almost 10000 years tech are we fucking retarded?
>>13264871Im only 38, are you telling me people did things 100 years ago?
>>13264966What do you mean by clean and effective? Normal rockets work so by definition they are effective
why are we still use boats, its almost 900,009 years tech are we fucking retarded?
Politics. We could have nuclear powered rockets in operation by now, but people fear the slight increase in cancer risks if there's an accident.
>>13264882OP is 100 years old tech?
>>13265043What if we built a "rocket" that was basically a trebuchet mounted on an aluminium cylinder, which threw rocks down toward the ground in order to accelerate into space?
