Nothing has ever gone faster than the speed of light.
When you ask about the rocket in Pokemon Ruby and Sapphire, I assume you ae reffering to the rocket that it supposed to take to you to the moon so you can catch Dexoys. Many people belive this is true (like me) and some people don't. But, to make the rocket gain launches faster, go to a stretch of land (no grass) and tape down the arrow key pointing in the direction you want to go. Now just leace it overnight and it is okay if you run into a wall, because the rocket gains launches depending upon how long you play! Before you do this, make sure your gameboy is plugged in or FULLY charged, so you don't run out of go juice.
A small rocket might go higher because a smaller rocket has less weight
a rocket 6540
it pushes the rocket into the air to make it go higher.
You can't make them go faster.
Just add more water to it. Also you can use gasoline and vegtable oil and mix them together some how and then it will react alot more.
