So the real question becomes how many canaries does it take to fill a 747?With the average weight of a canary being 15g, that's 3,333,333 canaries.
Just to ease yr pain knowing such stuff shouldn't make any difference to your life, unless of course the canaries got into the cockpit distracting the flight crew and the plane crashed into your house!I'm not sure if you are right there OME. But this whole business makes my head spin on account of how I'm not really smart enough to figure it all out.
Once I tried to learn how to derive E=MCsquared but I failed. So I though about getting a brain transplant. There sure are some smarter ones out there.
Sorry for making this sentence obscure. Hope this explains it better.If both spaceships are travelling at the speed of light, then their electro-magnetic images would be travelling at the speed of light also.
