"<a href=""https://www.youtube.com/watch?v=-jA2ABHBc6Y&amp;t=1h09m55s"">1:09:55</a> Her information on Starshot isn't all correct. She says multiple times "1/20 the speed of light". That's what's not accurate. 1/20 would be 5% of the speed of light. The actual", and accurate speed would be 20% the speed of light. 100 million miles per hour. The correct fraction would 1/5. <br><br>I just wanted to clarify that, as what she kept repeating is about a quarter of the actual projected speed. That's a pretty significant difference.
