Asteroid to pass by earth Sunday - too close for comfort

[cantthinkofanything]

Hey your the one doing it to yourself

I don't even know what your pic is supposed to mean other than that you have access to a pic of a guy with balls in his face. I'm glad you didn't post your nsfw pics.

you can't use the perceived distance from the graphic. If they put the asteroid at the exactly distance by scale, it'd be too close to tell what the was going on. That's why they labeled it.

If it would be too close, they would have just zoomed in, not put the path in the wrong place.

[pgardn]

others dismissed with "crazy" ideas

Mendel
Galileo
Zweig
Popovich
Einstein

So try proposing some insight into things we don't have a handle on, like the people on your list did.
Why is gravity so weak compared to electromagnetic force? Speaking of unification...

Batter up.

lmao. If they zoomed in, you couldn't see the whole earth and the change in distance.

Batter up.

I could try to explain to my dog how evaporation works but she's not going to get it.

[pgardn]

yeah but if said asteroid were to approach earth, when it is approaching surface level its acceleration would be 9.8

No not when it is approaching, at the surface, assuming there is no atmosphere.

Ok.
Explain it to yourself, but type it out here.

right, i meant as it was near the earth's surface. at the moment of impact

[Brazil]

so it's 20 miles or 25 000 miles ?

[hehateme]

Seems to be. Unless he is trolling.

The answer is in this post.

[lefty]

But did Earth dieded ?

[pgardn]

Yep, assuming there is no atmosphere.

Think about a parachute falling at a constant velocity, it's running into so much air.... If this true there is no acceleration.
The force of air resistance = force of gravity on the parachute if it falls at a constant velocity, therefore 0 acceleration.

in fact when the asteroid enters the atmosphere it slows down so it is actually accelerating away from the Earth. Some would say decelerating.

explain the theory of unification on Spurstalk message board. to myself. on Friday at 3:30.
what are some other choices?

[cantthinkofanything]

yes. asterood shoosted through the earf's clouds and didded the earth to dieded

No just evaporation, the thing your dog can't get.

An asteroid would fall nothing like a parachute.

[cantthinkofanything]

An asteroid would fall nothing like a parachute.

it would if they weighed the same

[pgardn]

An asteroid would fall nothing like a parachute.

It would fall exactly like a parachute if did not change velocity from an acceleration point of view, both would be 0.
But the asteroid would have a larger constant velocity. Yes.

[cantthinkofanything]

No just evaporation, the thing your dog can't get.

zoooom.

let me dial it back. you can teach a 3 year old that 8x8=64. but he's not really understanding what it means. People can train dogs that 1+1 = 2 bones. But they aren't really understanding the concept.

[Aztecfan03]

it would if they weighed the same

If they weighed the same, it would be a small asteroid with nothing close to the air resistance the parachute has and thus it would fall nothing like the parachute.

[pgardn]

it would if they weighed the same

No it would not. It would not even if they had the same mass. Shape makes a difference when air is present.

let me put it this way to you...

which weights more, a ton of asteroid? or a ton of silk?

[cantthinkofanything]

No it would not. It would not even if they had the same mass. Shape makes a difference when air is present.

I thought we were talking about in space.

Ok.

Still would like you to write about evaporation.

[Aztecfan03]

I see what you are saying now. You are saying it will reach its terminal velocity.
