Fastest star ever seen is moving at 8% the speed of light
- HenryKissinger 6y agoRelative to what? I'm moving at 100% the speed of the light relative to the photons passing by me.
- badrabbit 6y agoAn observer on earth?
- ceejayoz 6y agoIt's more likely in relation to the black hole it's orbiting.
- yostrovs 6y agoA very Henry Kissinger thing to say.
- wcoenen 6y agoIt's relative to Sagittarius A* , the black hole at the center of our galaxy, which this star is orbiting. Or you could say relative to our galaxy, since Sagittarius A* appears to be stationary within it. However, 8% of the speed of light (24000 km/s) is so fast that the orbital speed of the sun in the galaxy (200km/s) and the orbital speed of the Earth around the sun (30km/s) are negligible in comparison. So you might as well say that it is relative to Earth.
- throw149102 6y agoI don't know enough physics to give a proper answer, but I think this example is wrong. I don't think you can measure your speed relative to something moving at the speed of light, because there is no reference frame for the photon to be 'at rest'. Even in the photons own reference frame, it's still moving at c.

- lmilcin 6y agoNo, you are not. Photons do not experience time and so there is no such thing as photon frame of reference. Moreover, photons (in vacuum) will always be observed to travel at the same speed regardless of the observer's frame of reference.
