Do all the planets revolve around the sun in the same direction?

do all the moons of the planets revolve around their respective planets the same way? if not why not? if the universe was created by a big bang where everything collapsed in and exploded why doesnt it all spin the same way?

Yep. All planets revolve around the Sun in the same way.

I don't know about moons though but they wouldn't necessarily spin the same way, as they were created by asteroids and other large objects hitting planets to make the moon.

Although, as stated by squarebear, all planets in our solar system rotate about the Sun in the same direction, there are some interesting anomalies. Such as Venus rotating in the opposite direction of its revolution about the sun (retrograde motion). A number of the moons in the solar system exhibit retrograde motion, as well. The Sun rotates on it's axis once every 25 days, but not all at the same time due to its gaseious nature.. Interestingly, Uranus rotates on its side, tilted over some 98 degrees. Pluto, which has, in the last year, been declared person non grata as a planet, has a highly elliptical orbit around the Sun, taking nearly 248 years to make one orbit..

By the way, your view of the Big Bang doesn't comport very well with current theory... It didn't collapse out of a preexisting universe, but, rather, appeared suddenly and expanded at least intially, at speeds much greater than the speed of light (c from the Latin celeritas (speed))... .

[greg1957]

so current theory says the universe appeared out of nothing?

Ex nihilo...
