The radius of this would be 1.76 x 10^14 m, which is 1.86% of a light year, since light travels at 3 x 10^8 m/s and there are 31,536,000 seconds in a year.<br /><br />The difference in radius between year 9,999 and year 10,000 is 5.83 x 10^11 m, which equates to the radius expanding at an average velocity of 1.85 x 10^4 m/s or 18.5 km/s. Still fast, but nowhere near the speed of light.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-73039868835369855922015-05-18T00:27:32.295-05:002015-05-18T00:27:32.295-05:00Oh wait...

Look to the human race 10,000 years ago - it had nothing. Stone age. People then could not even comprehend where we are now. <br /><br />In 10,000 years, we surely will have developed an energy solution. We may have the technology to live on Mars or Venus. We may live under the oceans, or underground. We may agree on an economic model that doesn't require constant growth (as capitalism does). We may flatten out our birth rates, like Japan or Italy have. The point is, 10,000 years, although very short in the history of our planet, is a very long time in the history of our people.NoPoliticiannoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-85760728738683354032015-05-15T09:10:12.578-05:002015-05-15T09:10:12.578-05:00That was the Hans Rosling, yes?

At least up until we reach a unimaginable point in the future where wealth is as abundant as saltwater in the oceans - at which point the discussion about growth will have become obsolete anyway...<br /><br />This is why one has to be really careful when using a word like growth that means very different things in different contexts.
