Strange Comet Discoveries Revealed by Rosetta Spacecraft

Spinning spaceships creates artificial gravity by using centrifugal force to keep the contents stuck to the inside of the outer wall, like some amusement-park rides.

If you read the article you will see that there is hardly any gravity at all.

So gravity is not the answer which I was aware of before I asked the question.

Funny thing is everyone who told me gravity is the answer is wrong but they looked like bigshots doing it.

How many will admit it?

[winodog]

IC so that would not help the outside stuff.
So say I jumped off that rock and escaped what little gravity there is, would I be left stranded there in outer space or would the momentum force me along with the rock?

Parts for a 747 will not attach themselves at the molecular level. Certain chemicals will.

Many connectors and fittings in a 747 do attach in an analogous way. And just like a living cell there are lots of connections that do not. Not without help. So a better analogy might be to drop all the dies and fittings needed to assembly the plane in the box too. And shake harder.

[DuncanWaring]

I’m not sure what you mean by “would the momentum force me along with the rock”, but essentially you would go one way at some velocity, and the rock would go the other way at a much-smaller velocity.

You would eventually end-up floating out there in space until something else came by to gravitationaly attract you to it.

Fascinating discovery. Too bad the CREVO crowd has hijacked this thread.

Researchers working with Rosetta have found that the comet harbors organic compounds, carbon-based molecules that are sometimes known as the chemical building blocks of life.

Thanks left that other site.

That answers the question, thanks. I probably got a little too defensive over the gravity stuff.

[DuncanWaring]

Keep in mind also that “artificial gravity by spinning” kept many an unfortunate B-17 crewman stuck to the inside of his airplane after a wing had been blown off.

Don’t forget trees turning sunlight and CO2 into sugar.

In space, you have a much broader spectrum which includes protons, neutrons, and heavy charged particles. There are then many opportunities for change.

They do say may!

I gave up with all this horse shit many years ago when I started to get
better acquainted with how very special the earth environment was formed.
In order to sustain what we consider life forms.

Thanks Ernest!

They start with sugar, then polymerize the sugars into cellulose and xylose.

Maple syrup is tree sugar.
