  1. Correct, speed is only relative to an observer. But relative to any particular observer, nothing travels faster than the speed of light in vacuum.

  2.  @rachelbuckley4499  I thought I heard more like 300k years.

  3.  @paytonpryor  Come to think of it, it is redundant. Joining me is inherently with me. I live in Virginia and have for many of my formative years. I don't know if I have actually used or heard "join with me as I do such-and-such"; I'm just saying it doesn't grate on my ears and doesn't sound ambiguous. I think that if I heard it, I would not notice anything unusual. So, I'm concluding that it doesn't violate my internalized grammar.

  4.  @Nikkeftw  Even if they can cause harm, it may be reasonable to judge that the harm of passing on the virus is greater.

  5. That would be relative to an observer who is not "traveling through space", whatever frame of reference you mean to refer to by that phrase.

  6. Especially if they are supposed to be octal digits.

  7. Those craft got out there via gravitational slingshots around several planets. The opportunity to do that doesn't come along often.

  8. Johns Hopkins, not "John Hopkins".

  9. Are those digits supposed to be an octal representation?

  10.  @rubenmanssens  Incorrect.

  11.  @rubenmanssens  "Let’s say you and someone else traveled towards each other at half the speed of light. From your perspective it would seem that they’re approaching you at the speed of light." No, it would not seem. To calculate what it would seem like, you have to use the Lorentz transformation.

  12.  @OleOlson  "it would take about one year to reach the "speed of light" compared to their starting point (Earth)." No it would take infinity years. Calculating based on Galelean relativity won't give you the correct result when the quantities involved put you in a relativistic regime.

  13. No, you don't look around and contemplate. You get out.

  14. We could say it in the US.

  15. Only 300k yrs until it gets there.

  16. He was talking about the latency.

  17. "just" but there's mass and the Rocket Equation.

  18.  @Nikkeftw  for someone to be so sure (with proper grounds), they would have to have studied epid and kept up with the latest in the field.

  19. I wonder how precise it has to be. The beam must spread.

  20. Too bad that it's all probably going to end so soon.

  21. Does "seven times brighter than" mean "eight times so bright as"?
