I find it quite silly when after having done science seriously for less than 200 years we think we understand all of physics, especially when our models clearly have gaping holes and contradictions.
Nevertheless you don't even need new physics for this line of speculation. Fusion rockets will do.
- valuearb 9y agoFusion rockets are easily detectable. Essentially they would decelerate by sending an HBombs amount of particles our direction every few seconds.
