CAN PLANETS COLLIDE....(PLS READ)

we know that earth is revolving in its orbit,the circular motion provides the neccessary angular but its lmomentum,but its a physical thing and physical change takes place as its natural,what if the earth bends more on its axis or loses its orbit and collide with other planet..........can this happen?

This can happen in past many if new planets are formed due to colliding of two planets. Even earth can collide with other planets but till then enjoy

This probably already happened to young Earth (Theia hypothesis): a Mars sized proto planet impacted proto-Earth making Earth slightly bigger and creating the Moon.

This could happen again. The stability of planets orbits is not guaranteed. In the long term orbits become chaotic.

A statistic model had been recently computerized. 1% simulations showed an impact within 5 billion years between 2 inner planets Mercury, Venus Earth or Mars

The solar system has long since (over the last few billion years) settled down to a stable configuration with the major planets nicely spaced out and in no danger of collision with one another. All the long-term orbit changes are cyclic, so the stability of the solar system is likely to remain until the Sun expands in about 4 to 5 billion years.
Colliding planets is something from science fiction, but in reality, it's nothing to be concerned about.

If Earth's tilt changed, which it did after the chilean earthquake in 2010, our days become shorter/longer depending on which way it tilted. In the Earthquake I mentioned, it shotened our days by a millionth of a second (or something close to that number). Coinsidentally, tonight I was watching a doc on earthquakes and it would seem if there was a monsterouse one (above10.0) some crazy s h i t like you mentioned seems likely. (in my opinion)

Now, the sun is flipping massive and for the earth to be knocked out of orbit, would have to be a change in the sun. But the idea of a super monster earthquake, imagine like a 14.0+, could significantly knock our tilt out of wack, and in addition to our day/night cycles changing, who knows what other cosmic catastrophes could take place.
