Will pluto and neptune ever collide?

No, not unless some other unknown significant mass alters the orbit of either body. Although Neptune and Pluto "cross" due to Pluto's highly irregular and inclined orbit, at no time does Pluto ever intersect directly with Neptune's orbital path. Hackett out.

From Wikipedia, about orbital resonances: The dwarf planet Pluto is following an orbit trapped in a web of resonances with Neptune. The resonances include: A mean motion resonance of 2:3 The resonance of the perihelion (libration around 90°), keeping the perihelion above the ecliptic The resonance of the longitude of the perihelion in relation to that of Neptune One consequence of these resonances is that a separation of at least 30 AU is maintained when Pluto crosses Neptune's orbit. The minimum separation between the two bodies overall is 17 AU, while the minimum separation between Pluto and Uranus is just 11 AU.

Pluto and Neptune can never get closer than 300 million miles to one another due to the tilt of Pluto's orbit. Earth is always closer than 300 million miles to both Mercury and Venus, and usually is closer than that to Mars, yet no one but a nutcase coming up with new and more ludicrous doomsday scenarios would ever suggest any of those will collide with Earth

No. Pluto's orbit is inclined w/respect to Neptune, larger, but highly eccentric. Because of this eccentricity, roughly 20 years out of its 248-year orbit, Pluto is closer to the Sun than Neptune. There are 2 points where it would be technically possible for them to collide, but they're not in the same places in their orbits to allow this.

Not without significant perturbation of their orbits. Pluto's orbital inclination is such that its orbit and Neptune's never actually cross through the same space. Instead, Pluto passes about 8AU (1AU = Earth-Sun distance) ABOVE Neptune's orbit at the "crossing" point. Second, Pluto's orbit is remarkably stable relative to Neptune's, and barring outside interference, one would expect to see very little change in the relationships between the two over a span of millions of years.

The solar system is about four billion years old and those two planets Neptune and Pluto haven't collided. So I don't think that they will collide in the future.

It is possible but the most likely thing is that Pluto is shot into space or into changes it's orbit due to Neptune's gravity. However it could be caught by Neptune's gravity and become a captured moon but there is a only a very small chance of colliding in the far future as pluto's orbit is irregular and decaying.

It depends and if it's possible..I'm sure it wud take millions of millions..maybe a few billion years, years to happen and plus if it did take billions of years..the sun would be tranforming, by transforming I mean going through a normal star life cycle and eventually the Starr wud expand this would highly affect all of the planners orbit and gravitational pull and thus most likely wouldn't happened This what I think might happen..I might be wrong

No. It may look possible from a two-dimensional map of the Solar System, but because of the tilt of Pluto's orbit, they never intersect.
