You never spoke more on this. Did you just mean in general, like an asteroid killing us, quasar, black hole, etc., or are you taking about a specific threat?

I'm in the mood to be terrified.

Asteroid impact is the most likely - in fact, on the list, it is the only event that carries a near 100% certainty of happening...

Good news with asteroids is that we have the ability to see them coming; so, there's a chance we could maneuver one out of the way. Bad news is that the government spends almost no money on our space program and scientific advancement, so we'd probably not know in time.

Quasars do not likely pose a real danger to humanity due to the distances between galaxies and the fact that none of our surrounding satellite galaxies are believed to be large enough to support a supermassive black hole.

Black holes have different ways of affecting life on Earth.

Either through standard black hole / neutron star ejection or worse still a binary black hole could fail to merge, ejecting one of the singularities out into space at very high relativistic speeds. This might happen to be in our general direction.

If such a black hole collided with the Sun (unlikely but possible), then it's pretty obvious what the outcome would be.

However, the more likely outcome is that the black hole would pass through the plane of our solar system disrupting the orbits of the planets with respect to the Sun. That could be equally catastrophic.

Understand that such fast moving black holes, even though moving at nearly the speed of light and being only a few kilometers across, would be (on avg) around 7-10 times the mass of our Sun, having that much greater gravitational pull on the surrounding planets.

As it passed through the plane of the solar system, the potential to rip the planets out of their stable orbits would likely become a reality. Earth would almost assuredly suffer potentially permanent catastrophic climate changes.

And as Mar mentioned, gamma ray bursts round out the list.

Like fast moving black holes, gamma ray bursts resulting from hypernova events throughout the universe are only detectable once they arrive since they move at relativistic speeds (gamma rays moving at c, and resulting charged particle jets moving x->c). These events are extremely dangerous, but, generally rare. In fact, these events are so rare, that there is no certainty that a gamma-ray burst within our galaxy or in a close enough galaxy would reach Earth while it is still habitable. This is the least likely extinction event.

Ultimately though, on a stellar scale, the Universe itself will eventually become uninhabitable and completely incompatible with all life, so, extinction is almost a certainty at some point.

Hope that answers your question.

Bah. Gamma rays = cosmic powers/fantastic 4 powers.

Hahahaaha!

Yep, I am now educated and moderately terrified. Thanks Gourimoko!

Don't worry you'll be hit and killed by a baby boomer who hit the gas instead of the brakes before any of the cosmic shit happens.

I've seen a number of your posts around this site related to space & physics all of which are highly insightful. How'd you manage to become so knowledgable on these subjects?

Thanks!

Mathematics and physics were my fields of study. I have masters degrees in both, and worked in the Physics and Astronomy department while finishing grad school. My background is in computational simulation and modeling of astrophysical phenomena like star and galaxy formation, gravitational collapse, etc.

I considered getting my PhD but, made a different career choice a few years back. Financially it was the right decision, but I do miss academia.
