Light speed and Astronomical Unit question. - DiscussWorldIssues - Socio-Economic Religion and Political Uncensored Debate

The distance from the earth to the sun.

It makes sense for like solar system stuff, but I'm not sure if it makes sense to measure ship warp speed in it...

The AU is a measurement of distance not velocity.

They just tossed a per second on the end to make a velocity measurement.
But it's used in real astronomy circles for distance, not velocity.

Spec. Huh?

Calculating distances using light*time is pretty common. Even within the solar system light delays are on the order of minutes and hours, which factors into space travel communication.

Light takes roughly 8 minutes to go from the sun to the Earth, thats 60*8=480 seconds, Light would cross 3AU in 480*3=1440seconds so a speed of 3 AU/sec is 1440 times the speed of light. According to TOS Warp measurement scale that would be equivalent to warp 11.3 by the method of cubing the warp factor to get the multiples of c.

What about your headlights, if you're going at the speed of light? A beam of light heading towards you will still be travelling at the speed of light. That's the cool part about it.

I know how to go faster than light.

If'm in Slow's car doing nearly the speed of light, I can slip stream behind another car and get a sling shot when I put my foot down.

Einstein never thought of that

It's a credit to the man he was thinking about health and saftey even when overturning the established order
