Had a fun time hanging out for +Mach 30 at +Catylator LLC Club with Mark Potter (from @OuroborosSpace) and Andrew Reed (from @CosmosPioneering) and J Simmons. Awesome quote of the night: Q: What’s the deal with the Karman line? A: Above the Karman line a plane can't "plane" anymore. So it has to "space ship" - +J. Simmons
Many assumptions were made here, primarily that technologies remain static or develop in an iterative process. While this is generally true over the short term, major leaps happen quickly in isolated revolutionary advances.
Statistically, it is highly likely that by the time we need to expand beyond our galaxy, and later supercluster (on the order of millions or billions of years, we should develop the means to do so.
