The axial tilt was not caused by an impact. An impact could cause a wobble, but not a constant 23 degree tilt.
FYI
Welcome to Free Republic.
I've been taught that since the Earth is an imperfectly balanced object, it "wobbles" like any other unbalanced spinning object. Wobbles like a top nearing the end of it's spinning. To finish a complete wobble circumference takes about 26,000 years so today's inclination (23.5 degrees) as to the sun will lessen and increase as this cycle progresses.
It is a large wobble. If one circumscribes in the sky via the axis into the heavens, the circle currently extends from near Polaris (today's pole star) to Vega (the pole star in 13,000 years).
Probably when the expression "Crapped Pants" was invented.
Tiamat ping.
You guys are way beyond me; it is clear from my perspective, however, that earth has endured cataclysmic events which substantially altered the course of human events. Judgements, some would say.
Either we are random organisms adrift in the cosmos, or we aren’t.
Your call.
That sure does look like a sideways impact but the rest of it just sounds silly.

Giant Crater Found [in Antarctica]: Tied to Worst Mass Extinction Ever [Permo-Triassic]
“An apparent crater as big as Ohio has been found in Antarctica. Scientists think it was carved by a space rock that caused the greatest mass extinction on Earth, 250 million years ago.”
“The crater, buried beneath a half-mile of ice and discovered by some serious airborne and satellite sleuthing, is more than twice as big as the one involved in the demise of the dinosaurs.”
“The crater’s location, in the Wilkes Land region of East Antarctica, south of Australia, suggests it might have instigated the breakup of the so-called Gondwana supercontinent, which pushed Australia northward, the researchers said.”
“This Wilkes Land impact is much bigger than the impact that killed the dinosaurs, and probably would have caused catastrophic damage at the time,” said Ralph von Frese, a professor of geological sciences at Ohio State University.”
“The crater is about 300 miles wide. It was found by looking at differences in density that show up in gravity measurements taken with NASA’s GRACE satellites. Researchers spotted a mass concentration, which they call a mascon—dense stuff that welled up from the mantle, likely in an impact. “
Sounds like Velikovsky’s “Worlds In Collision”
mdraghici, despite the conservative tone of this website FR is very pro-Darwinism. Several cutting edge science types got banned here a few years ago just for posting anything anti-Darwin and pro-Velikovsky.
That was the foundation dig for Art Bell’s summer cottage.
Sci Fi ping!

Bull Puckey!
Worse, you have a group of four planets with the same 23 - 26 degree tilt i.e. Earth, Saturn, Venus, and one other which no impact would cause. What appears to be the case is that our system is a composite system, i.e. a larger system including the sun appears to have captured a smaller one.
The “cutting edge science types” who got run out of here were very much pro-Darwinist; it was more than two years ago; and the website owner is very much NOT pro-Darwinisn. IOW don’t believe everything you read above this message. :’)
The images look compelling, but an impact causing the tilt may be a bit of a stretch.
Very interesting, none the less.
If those geographical features WERE created an impact, I bet that caused one hell of a shake!!! (wouldn’t have wanted to be on the planet that day - Well... Maybe I would.) lol
How did your SciencePub/Marsland Press get the same address as Brookdale University Hospital Medical Center?
If the Earth is a-rockin’ don’t come a-knockin’
re mdraghici article in 2010 that cosmic impact caused Earth axis tilt and wobble...check out new evidence in BEFORE THE DELUSION by Wm Gleeson, recently published in UK.
Similar proposition as mdraghici but with a lot more and different ‘evidence’. an interesting and entertauning read. RossMelb
