But the author assumes that direction of signal propagation is relativistically invariant.. With respect to Carol/Dave's frame of reference, the signal went from Bob to Alice, and the top arrow should be pointing to the left. With respect to Alice/Bob's frame of reference, the signal went from Dave to Carol, and the arrow of the diagonal side should point to the upper right. Is there a single reference frame with respect to which the arrows point as the author has them?
No, nothing can go faster than the speed of light because it will violate causality. Which is more or less forbidden by the entirety of physics.
It is true that faster-than-light travel would mean that we have causal sequences whose order is frame dependent, but would that be a violation of causality?

Are you using LibreOffice on the same computer as Microsoft Word? Is docx a device-independent format?
But is it easier to place complicated math in Powerpoint than to do so in LaTeX?

Arrive earlier than it was sent with respect to what frame of reference?

I took the original poster's use of SQL server to denote a Microsoft product.
Get rid of your Steve Jobs altars!
How are SQL Server's idiosyncracies different from Microsoft's? Isn't SQL Server a Microsoft product?
Isn't having his friend state that the card is the king of spades a measurement?
What happens when they attempt to hand out the 1,000,000,001th SSN? Or do government officials somehow trump combinatorics?
Would you still a 1992 desktop, even if the parts were fine?
We're about to have a Mormon president in these United States.
Is President Obama converting? Or do you believe that Romney will win?
Does the Queen's genealogy even date to 3,000 years ago? Weren't her ancestors German at that time?
If you think that Roger Penrose and Steven Weinberg amount to intellectual masturbation then I guess we would find ourselves at odds.
Penrose and Weinberg may be brilliant, but that doesn't mean that this particular question is worth pursuing.
Why are you not fencing your unnecessary belongings and helping the poor starving people?
Because you can only fence stuff that you stole.
what exists outside our universe and what existed before the Big Bang.
Are you using "universe" as a synonym for "spacetime"? Wouldn't something outside of our spacetime still be in the universe?
Phoenicia was roughly where Lebanon is now, and Scythia is more like Ukraine/Kazakhstan. How do you get the United Kingdom?
I wasn't so much trying to defend Apple as pointing out how business in general operates.
Yea, brag that you not only you're dumb enough to get paid more
What's dumb about about getting paid more? Besides, I don't even own any Apple products.
Believe it or not, there are some businesses who make money but who also deliver what the customer wants.
Like Apple?
Editing the registry is a given in Linux? This might be the problem.
OS X has already surpassed Vista
But it's at only one third the market share of Windows XP. Also, how many computers would Apple produce, and at what price?
What if the fridges use chugging caffeinated soda as an input method?
Don't be giving Apple ideas.
But it is only about money, though. Beyond that, Apple doesn't care about users either.
And beyond money, does any business care about its customers?
If Romney wins the election, we'll have commander-in-chief Willard running an army of rats. Wasn't there a movie about this?

But Saddam Hussein was a counterweight to Iran. Did we topple him to make Iran more powerful so that we could use it as a bogeyman?
OSX is quite affordable. The computers it runs on are expensive.
