Neither rockets - nor anything else man-made - can get into space, so it must be some other technology.
Think about it, then return with Answers rather than Questions & maybe we'll give you the time of day...
Until then, f**k off.
'Neither rockets - nor anything else man made can get into space......'? Really?
The documented and observed evidence plainly shows that ROCKETS CAN GET INTO SPACE. Why wouldn't they? If your answer is going to be something along the lines that rockets need an atmosphere to push off, then sadly your knowledge of physics is virtually non-existent. The Apollo Saturn V rocket's 1st stage engines ejected 15 tons of burnt fuel every second, at a speed of over 4 km/second. Newton's 3rd law of motion states that for every action there is an equal and opposite reaction. A rocket engine is reactionary. In other words, the action of the huge mass of burnt fuel travelling at hypersonic speed going in one direction causes the rocket to be propelled in the opposite direction. If anything, the atmosphere actually impedes a rocket's progress due to drag, until it reaches higher altitudes, where the rocket engine becomes much more efficient due to a lack of atmosphere.
Why doesn't a car's exhaust push it forward. It may not go as fast as a rocket, but surely it should move a little.
Exhaust does push a car forwards. By an amount so small it's incomprehensible for the human brain, that it's practically zero.
I didn't realize that. Why do we need jet engines, why not just use rockets on planes?
Oh my god, you actually don't know much about anything do you?
The fuel used in an aircraft's jet engine is a derivative of petroleum, is cheap and plentiful and can be contained easily within the fuel tanks of an aircraft. These tanks do not need to be pressurised either.
The fuel used by rockets on the other hand, is extremely expensive to manufacture, highly volatile and requires constant pressurisation, and normally involves 2 types of fuel (liquid hydrogen and liquid oxygen) that must be contained separately until they are mixed in the combustion chamber.
The fact that you would even ask the question as to why rockets are not used on jet aircraft is a sad joke.
There have of course been aircraft that have used rocket engines, but these were only experimental. The X-1 and X-15 being examples.
