This is the Alcubierre warp field bubble: \"gravity\" in front of the ship and \"antigravity\" in back of it. The ship itself is in the non-curved space-time in the center of the bubble. The ship is rendered after the warp effect, so didn't look distorted (I don't know how to implement accurate rendering of models in a curved space-time). Note what in reality such view is impossible: observer can't move together with ship while staying outside of the bubble, because his speed will be superluminal.<\/p>\n

The Universe background is blueshifted while looking from the \"gravity\" region and redshifted from the \"antigravity\" region.<\/p>\n

From the center of the bubble, the Universe looks undistorted.<\/p>\n

The warp field visualization is fake. Equations for light path in the Alcubierre metric are way to complex to be implemented in the code, at least for now. Maybe a few SE versions later, when I implement the Kerr metric for rotating black holes, I'll also implement an accurate rendering of the Alcubierre warp bubble.<\/p>\n
