Does it have to take 8 minutes for it to be felt on the sun ?

A little longer than that, in fact.

No. Much more longer time. More than 9 months.

Your push is a pressure along the stick. The speed pressure advance is equal (almost) with the speed of the sound (sound is a form of pressure) in that material.

For example, the speed of sound in steel is 5 960 m/s. The currently accepted value of the Astronomical Unit (distance Earth - Sun) is 149 597 870 691 m. So, the Sun will be pushed away by you :-)) after 25 100 314 seconds. This means almost 9 1/2 months. I don't think it's worthy.

No, the push doesn't travel at the speed of light - but at the speed of sound, which is much slower. The Earth is 93 million miles from the Sun, and sound travels about 5 miles/sec. So it takes about 20,000,000 seconds, or about 230 days for the Sun to feel the effect.

The speed of the push would travel along the stick at the speed of sound in the stick. Assuming the stick's made of wood and ignoring any temperature effects, it would take about a year!

It will take a lot longer than 8 minutes because the compression wave in the stick has to travel the distance. Unless it's an imcompressable stick, then it's instantaneous

Since the stick would have to be so long it would be far to heavy for you to push it... so it would never be felt on the sun. Trick question here :) Have a good weekend!

I don't think that it would. No part of the stick is moving faster than your jab which is probably just a few miles per hour. However, the energy to move the stick would be kind of immense. By my quick guestimations, assuming that each foot of the stick weighed 4 ounces, the stick would weigh somewhere around 61 million tons.

I think the stick would catch on fire isnt the sun pretty hot :)

depends on the stick,definetly not 8 min
