The tilt of our earth

[timojin]

But a change of inclination of the orbit will result in a change in the obliquity.
The top image shows a planet with an obliquity of 0 (axis of rotation at a right angle to the orbital plane).
The bottom shows the same planet after the inclination of its orbit has been changed, Since the direction the axis of rotation doesn't change, the angle between the rotational axis and the orbital plane does, and we get a different obliquity.

Yes timojin you are correct.Janus has put it quite succulently and as agreed with what most of us has been telling you. But because I'm a real nice bloke, let me also add another factor...Gravitational perturbations. eg: In a few thousand years the star "Barnard's Star" will be the closest star to our system, deposing Proxima Centauri. This could theoretically have an effect on the obliquity or axial tilt, and obviously this also may have played a part in the distant past.
So along with what you were told as far back as in post 3, along with the violence and accretion that was responsible for our solar system, gravitational perturbation/s by another probably stellar size body as per Barnard's Star, would also play a part.
Hope that helps.

river:

Yet hard science has no clue as to why the Earth is tilted .

You have been presented with at least one scientific explanation as to why the Earth is tilted. You reject that explanation, but have offered no reason for your rejection.

You cannot honestly claim that science has "no clue", since you are now aware of actual "hard science" that is suggestive of how the tilt occurred. If you continue to make dishonest claims that science has "no clue", when there are viable hypotheses out there that you are aware of, you will receive an official warning for telling lies.

Ah so. Missed that. But that seems unlikely in explaining Terra's tilt - with the planets in more or less the same plane, but varying so widely in their respective axis tilts.

That would not cause a tilt, any more than activity in the Southern hemisphere would.

yes, this theory is extremely common, there are not enough evidences to prove it, so i guess we should ignore it and look for some more logical explanation.
