re: NASA makes emergency call as odds of ‘city-killing’ asteroid striking Earth increase

It’s estimated to incur an 8 megaton blast.
We’ve tested bombs that strength in the water. I don’t know if it will be a significant tsunami risk, depending on where it hits.

Well if this is anything like the 7 day hurricane tracker, it's usually better to be inside the cone because you know they probably got it wrong at first...

It’s not
Tracking these things is basic math. Once they get better eyes on it, there really aren’t any variables.

You didn't do the math, you estimated.
You could have done that by thinking 1/100 is 1%, and 1/43 is close to 1/50 which is 2%, so it increased by a little more than a percentage point to just over 2%
I did do the math. I rounded down to the tenth
1/43=0.02325
Or 1/43=0.0233 if you’re on an iPhone with the updated predictive keyboard and type “1/43=” verbatim.
I wouldn’t expect you to have an iPhone, the updated keyboard, comprehend the word verbatim, or remove the quotations marks tho

There’s some choice targets along this line

Yeah, that pesky atmosphere has a lot of tricks up its sleeve.

Does this mean it could also be smaller?
We've measured the asteroid's current estimated size based on the portion that is visibly reflecting light. The James Webb Space Telescope has instruments that use more than just visible light to better measure the size. And since JWST is in space and not affected by the atmosphere, it should provide a clearer picture, also providing for better measurements.
It's kind of like being able to look at an iceberg... right now, we can see the part above water. With JWST, we can see what's under the water too. (I am not saying that it is a guarantee that there is a lot more mass that we haven't seen yet, just trying to give a relatable analogy.)

If tracking this is basic math, why did the odds of a hit nearly double? It should already be set and stuck.
1 in 43 yet they know the less than 2% area of earths surface that will hit?
You are falling for fear porn.

That’s the estimated force AT IMPACT.

If an object the size of a tall building, traveling at around 23,000mph, cuts through the ocean and hits the bottom….what do you think happens with all the water that is displaced as it moves toward the bottom? What about the blast being at the bottom while water above is displaced?
I’m not saying we would have a 100 foot wave all along the coast, but the water would have to go somewhere momentarily

A large portion of that water would be vaporized. We'd still have a tsunami, but nothing like what we see in movies.

Yikes! From about 1% to about 2.3%.
I'll get my affairs in order.

City killer? That's baby shite. Wake me up when we get a country killa or a planet killa.
