Ladies and Gentlemen,
I would like to continue the thoughts of HRM Leonardo Da Vinci... Moving forward also means moving upwards because if you don't move forward it means that you are pressed to the ground by gravity...
A pair of wings always helps with elevation and escaping gravity - so you could maintain a pair of wings on the interstellar spacecraft perhaps... This would solve moving upwards (you always need that for flying in the Universe) and moving forward, too...
The big question is what would these wings lean on in outer space like the wings of an airplane lean on air on Planet Earth? Here you have my ideas:
a) The wings of the spacecraft could lean on starlight which you have got plenty of in outer space... However the interaction between spacecraft and starlight would cause maybe some environmental pollution... (The wings could be made of light, too...)
b) You could gild the bottom of the wings - so that you always have something under the wings... If you want a more intense effect you could also lead some electricity into the layer of gold...
c) You could fit wheels under the bottom of the wings which would facilitate moving forward and would symbolise gravity of a heavenly body...
You can have an effect on spacetime just by movement...
