Summary:
The sun's magnetic field reverses its polarity once every 11 years or so
Flip represents a peak in solar activity where bursts of energy are released
These bursts can lead to space storms and changes to Earth's climate
Radio and satellite communications may also be affected

For those who want a different perspective NASA has created a video describing the coming flip:

Remember all the havoc the last time this happened?
Me neither...

It has flipped, we know that for sure. Isn't it hypothesized this is one of the reasons dinosaurs went extinct?

No... it does it every 11 years or so...

You may be thinking of the Earth's magnetic field reversing itself (although I have no idea if it had anything to do with the dinos dying out).

Which I believe is going to happen again, possibly soon, and cause all the massive earth changes which have been predicted.
Anybody else on here ever read the works of the much maligned Immanuel Velikovsky?

Maybe so, maybe so.

I was thinking earth.
Been watching the How the Earth formed series on History of late... the formation of both Yosemite and Death Valley is fascinating...
It is one of many theories on how and why they went extinct. One being, of course the asteroid that smashed into Mexico’s Yucatán Peninsula, another being volcanic ash spewing into the atmosphere and blocking the sun and the other being the reversing of the earths poles, which has been proven to have taken place by drilling core samples and from evidence found in places where a lot of dino skeletons have been found. BTW the earths poles switch about every 700,000 years.. and there is there is a theory that large scale volcanic activity is more common at a time when there are many reversals of the earths magnetic field so the two may be inter-related.

I'd take the pole-switch/extinction theory with a large grain of salt. Occam's Razor suggests that the meteor impact theory is a much stronger candidate.
