that... seems odd to me. without substantial changes in velocity - how does a warp bubble (that's sub-luminal - so relativistic velocities) alter the fabric of space-time so fantastically? It's not moving fast: so where does the time dilation come from?!
- JumpCrisscross 2y ago> not moving fast: so where does the time dilation come from?! I think it’s from shifting momentum?? The paper is far beyond me [1]. But as I understood it, you’re directly modifying space-time with energy instead of using acceleration as a go-between. [1] https://arxiv.org/html/2405.02709v1 https://arxiv.org/html/2405.02709v1
- ben_w 2y agoThe mass distribution in the metric can do that; IIRC this was chosen in order to not have time dilation, so I think someone's getting confused (and maybe that someone is me?)
