This is how NASA would respond to an asteroid impacting Earth

a reply to: NicSign

My physics professor in college retired from nasa.
He did the math for satellite guidence systems.
I'll take his Ph.D. Over your opinion.

But...but...

I gotta admit, after he said "hello, I'm Doctor barns" he pretty much lost me...

There's math at the link. Sorry, I'm sure they said there'd be no math, but there's math.

Wrong laws.

I thought entropy would be a good starting point.

That's like reading the last chapter first.

Tabletop exercise? So they are going to get cases of beer and shots and give their elbows a workout drinking beer at the table. Well, if an asteroid is heading right at you, being prepared means having a bottle of your favorite booze in hand.

The statements irritated me from that poster about "air" just "sitting" on you.

It irked me.

Depends on how much warning time you have

If the object is coming from the daylight side, in the glare of the sun, may not have lot of time to react

If have time can probably cobble something to together to deflect it off collision course

May not be Bruce Willis and his crew, but probably get something to work

An object of the size described is highly likely to be discovered long in advance.

My point was that nasa can't put a man into orbit so I don't have much confidence they could move a trillion pounds of iron meteor.

any specific math you want to point out and how it relates to rockets?

i bet deep down he knows it's all a lie

Rockets, energy, dynamics, force, delta vee's?

Dude?

Take a physics course.

Please.

Even a basic one.

I have already taken physics. The problem is that I have already proven that there is no equal and opposite reaction due to pressure gradient force. You have not proven that there is. So rockets cannot propel in space.

Calm down, buddy, calm down. I'm pretty sure at this point that someone's cutting their troll teeth on the thread. 14 posts and they're insisting purple tastes like Manga & cocky as all get-out already, that's a red flag.

Either that or they're on the short bus donning a padded helmet.

So what? Everything else is moving and the rocket is just sitting there?

Are you saying there is no such thing as a rocket or that they use a secret force to move the rocket?

Wow, is there anything midichlorians can't do?

So I'm assuming that by following your idea to its logical conclusion, we have no satellites either?

So "station keeping" doesn't exist?

Fascinating.
