We must create giant space-surfboards to surf on gravitational waves. This
will allow spaceships to travel through time and matter very fast and is
much better than rockets based on fossil fuels.

Because space is just a giant black ocean and you can sail it with solar
sails or surf on its gravitational waves.

Easy.

Thank you! The answer was so obvious. How could we all have missed it? I
guess there's no need to keep working on my warp drive...
