How long would it take to send a message to the "Galactic Capitol" located at the center of the galaxy, then to receive the reply?
To give a sense of the difficulty of managing an intergalactic civilization, calculate the time (IN YEARS) it would take to send a message to the "Galactic Capitol" located at the center of the galaxy and then receive to the reply. Assume the message leaves the Earth and travels at the speed of light and...
-------------------------------------------------------

Jeffrey K say: About 30000 years for the message to get there and 30000 years for the reply to travel to earth.
60,000 years total
-
az_lender say: That distance is about 26.4 light-years, so the total time would be around 54 years (including the 1 earth-year during which they are deciding).
-
Starrysky say: First, center of most every galaxy is dominated by a super-massive black hole. It spits out hard radiation as it eats up gas, stars, planets and dust. No survivable place to hold a government together there. So your question is garbage.
Better is to be out in a safe zone, in a spiral arm, around many other stars and planets, and safe from the center black hole.
Now redo your question to reflect reality of the galaxy, not some foolish science fiction movie or book creator's fantasy. Then your galactic civilization might be credible.

Acetek say: around 52,000 years at the speed of light.
with quantum entanglement instantaneously
-
Sciencenut say: Forget about assuming the message travels at the speed of light. Quantum entanglement travels at a minimum of 10,000 times faster than light speed, and maybe much, much faster. Let's guess that the message travels at ~100,000 times light speed. Round trip would be a little over 6 months, plus one year to make the decision, so you could get your answer in less than 19 months.

CarolOklaNola say: 46,000 to 52,000 years, assuming there is little time delay before a response is sent. Different sources give different distances to the center, 23,000 to 26, 000 light years, or 27,000 light years (54,000 years). A light year is a unit of DISTANCE.

poldi2 say: So doing simple math is too hard for kids today.

The galactic center is 26,490 light years away.
So it would take 26,490 years to get there and another 26,490 years to return plus a year for the decision.
52,981 years.
-
Morningfox say: It would take about 26,426 years for the signal to travel that distance (one way). You can figure out the rest.
