erm just a quick question, as i read something that didnt quite make sense to me anyway, our sun will stay in its current form for about another 5 billion years before inflating into a red giant, now i was just browsing wikipedia reading up about various things, and was reading the article about proxima centauri which is the nearest star to us besides our sun. it stated that proxima centauri is one seventh the diameter or our own star, which understandably it would be in the main sequence for a longer period of time, however the time scale just seems a hell of a lot larger than can be right
surely that can't be right, in essence it will be in its current form for 4,000,000,000,000 years...
"The mixing of the fuel at Proxima Centauri's core through convection and the star's relatively low energy production rate suggest that it will be a main-sequence star for another four trillion years, or nearly 300 times the current age of the universe.
