Warp Space Travel: Is the Light Always Ahead?

ok last dumb question for tonight i promise... i have read that you can theoretically warp space (on paper not in a lab). let's say we built a warp drive however... if you were traveling through warped space say on the enterprise and shined a flashlight off the front of the ship would it still be relative off the bow (wave shift?) or would you keep catching up to it as you warped the next bits of space in front of you?

It's a moot question but I don't know the answer.

Beam me up, Scottie !
 
I think in the context of an alcubierre warp drive if you shine a light ahead of you, you should still perceive the light to move at c (at least for a short while). Within the bubble, at least, the spaceship does not travel faster than the speed of light, so we expect observers to find the time locally minkowski. At the boundaries, however, the question is trickier and I don't know the answer.

See: http://en.wikipedia.org/wiki/Alcubierre_drive For the scheme I'm referring to.
 

Thread 'A sufficient condition for integrability of equation ##\nabla g=0##'

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...

Thread 'Hawking After 54 Years Confirmed: BH surfaces don't shrink'

Abstract The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence of two black holes with near-equal masses ## m_1=33.6_{-0.8}^{+1.2} M_{⊙} ## and ## m_2=32.2_{-1. 3}^{+0.8} M_{⊙}##, and small spins ##\chi_{1,2}\leq 0.26 ## (90% credibility) and negligible eccentricity ##e⁢\leq 0.03.## Postmerger data excluding the peak region are consistent with the dominant quadrupolar...

Thread 'Relativator (Circular Slide-Rule): Simulated with Desmos - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...
