I thought Bruce Willis blew it up in Armageddon.

I started a conversation in an earlier post. Since this thread is about the threat of an impact event. I posit there is evidence all around the world of technology we can't explain. Whoever made these structures likely got wiped out by an impact event. Do the math, guy.

Is the objective to prevent this from happening actionable or realistic?

Even if we knew that a collision is imminent, the technology to prevent such an impact by changing the course of an object is extremely limited.
Not sure what you define as "large" but what about "tiny" ones like this that incinerate everything for 4 miles (radius)? These occur in the thousands of years, not millions, this particular one about 5500 years ago.

https://en.wikipedia.org/wiki/Kaali_crater

Here are a list of 7 big ones in the last 1 million years. The largest was capable of causing nuclear winter which would kill a decent % of the earth's population.

https://en.wikipedia.org/wiki/List_o...(10_ka_to_1_Ma)

Did you know what Chesapeak Bay is a crater? 35million years ago...50 miles across.
https://en.wikipedia.org/wiki/Chesap..._impact_crater

Again, not sure what you call "large" but the frequency of an event killing a decent % of global population is vastly lower than 100 million years....probably 1 million or less.

What are puny little humans going to do against a million ton rock traveling at 1000 miles per second?

There are numerous written records detailing how and when the various pyramids were constructed, the materials, number of laborers, techniques etc. This is just one source of literally thousands....including pictographs within the very pyramids themselves. They're also supported in the archeological record as they found various tools, blocks, pottery, ports etc. that corroborates this.

https://www.history.com/news/egypts-...d-construction

There is so much proof that the Egyptians built them, you might as well claim we just found Hoover dam in place where it is as well.

With carbon dating, you should know the age of the pyramids or other structures and then match it to the impact crater that wiped out these advanced global civilizations, you know like they did with the mass extinction of the dinosaurs. That would be the very first step before making such a claim.

There are various effective techniques out there, in general just nudging it a bit over a year can greatly alter trajectory.

P.S. Fastest recorded was about 18miles per second.

I'll comment later, but thanks.

Don't fund and MAGA. Make Asteroids Great Again.

I was pretty good at Asteroids around 1980 maybe they should hire me as a consultant.

The Dark Enlightenment said We will all feel pretty foolish when an asteroid hits and causes hundreds of billions of dollars in damage that could have been avoided with a few hundred million in funding for planetary defense.
If you think we would only spend a few hundred million you are dreaming. Maybe on the initial feasibility paper but...

We could perhaps start smaller. The Tunguska impact was in the range of 10-15 MT explosive yield equivalent. Not a dinosaur-killer, but if it was due to arrive in an inhabited area, some warning could be useful.

Seriously, if we're going to have NASA be anything but an organization that delivers government contracts to the right congressional districts, this is the exact sort of thing they should be doing.

I thought "asteroid" referred to a Democrat that is high on drugs.
