No it’s not. Pressure builds up between the gun chamber and bullet. Pressure pushes the bullet and gun. Like a compressed spring between two blocks. When the spring uncompresses, the spring pushes off both the blocks. A rocket is like a compressed spring attached to only one block. When the spring uncompressed, the spring only pushes the block as much as it pushes the air.
Quoting: Balance242 Matter to push off from is not necessary when there is an explosion. The explosion is what causes the object to propel. The controlled directional explosion moves the craft. Yes, just think of the exhaust particles as tiny "bullets" if that helps your tiny mind grasp the concept. It's not just "pressure", matter is being ejected from the rocket at high velocity. So I should ignore science and believe you, who has provided no demonstrative proof?
