| Jan 12, 2015 at 16:47 | comment | added | user3652621 | what book would you suggest for a more in-depth study of this? Assume basic calculus and rusty linear algebra. | |
| Jan 12, 2015 at 16:29 | comment | added | user3652621 | So a gravity well acts by essentially bending your future towards itself? Fascinating. Thanks for the answer! | |
| Jan 12, 2015 at 16:25 | comment | added | John Rennie | @SerbanTanasa: the magnitude of $\vec{U}$ is conserved because it's always $c$. The direction of $\vec{U}$ will change as you accelerate. | |
| Jan 12, 2015 at 16:22 | comment | added | user3652621 | Thanks! So my intuition was essentially correct, and $\vec{U}$ is the preserved unit? | |
