    It is not possible to have an infinite source of fuel.

    When reach space, we need force all the time at space. How to overcome that? Fuel? Sure not enough, then machine will damage always, we may need to bring a lot of part with us if we want to travel long way in the universe do we... beside, there is hundred thousand of star, gravity of them will always interfere our ship, then we need force to overcome it. Still many issue need to solve.

    Not an infinite source of fuel, but some have proposed using the hydrogen that exists in space as the fuel source. There are lots of issues, but it's an interesting idea:
