Travel times: something wrong

The table says:

Destination	1g	2g	5g	10g	Planetary time frame (all in years)
Alpha Centauri	4	2.8	1.8	1.3	5
Sirius	7	5	3	2.2	13
Galactic Core	20	11	5	2	30,000

But this can't be right. It can't be faster to get to Sirius than to the core William M. Connolley (talk) 21:28, 26 August 2014 (UTC)

Changed to the values listed at [1] for now, but we need a more reliable source. Rolf H Nelson (talk) 19:25, 30 August 2014 (UTC)

Looking at it more closely, the White source is obviously not a domain expert; for example he says, "If a ship accelerates at one G, then it will reach light speed in a year." The values may be right if he took them from somewhere else, but until we get an RS I'm deleting the table. Rolf H Nelson (talk) 19:31, 30 August 2014 (UTC)

Re-reading, I misunderstood the part I quoted from White; in context he means "almost light speed." However, the "Spacetime Physics" (Taylor and Wheeler) graph I copied from a different Wikipedia article gives different figures, and is based on WP:RS, so we can use those.

As a sanity-check, the (non-WP:RS) (possibly WP:RS) Physics FAQ that John Baez [2] hosts is consistent with the "Spacetime Physics" graph. Rolf H Nelson (talk) 17:55, 31 August 2014 (UTC)

Just a comment: though he is writing in a blog here, I would (ahem) never refer to Baez as non-RS. Juan Riley (talk) 16:06, 1 September 2014 (UTC)

Alpha Centauri Bb

I am not sure how to do this discussion thing but here goes. The planet Orbiting Alpha Centauri B is not confirmed. The Table should be changed to reflect that. The Wikipedia page on Alpha Centauri should provide the needed documentation. Anonomous — Preceding unsigned comment added by 2601:5:A180:117:2D8B:3C52:D5FC:9872 (talk) 02:43, 9 December 2014 (UTC)

Feel free to change it. Rolf H Nelson (talk) 07:58, 9 December 2014 (UTC)
