 For example, a typical one-way trip at an acceleration of 1 g from the Earth to the Moon would last only about 4 hours; to Mars, 2 to 5 days; to the asteroid belt, 5 to 6 days; and to Jupiter, 6 to 7 days.As shown by the transient mass fluctuation equation above, exotic matter could be theoretically created.A large quantity of negative energy density would be the key element needed to create warp drives as well as traversable wormholes.
