Understanding gravity

[Heyo]

It’s nice that you used her real name.

Also, I think we need something more evocative than just ‘the earth’ to name our living home.

It is so banal and dry. May as well call it ‘the old sod’.

I know there’s Gaia, but it doesn’t do it for me.

Any suggestions ? What is our planet called in other cultures ?

It's called Terra in Latin and you will find that on planetary maps and in scify stories.

 

[Heyo]

And, because the moon is less mess,

Yep.

 

[Polymath257]

That is the dogma that keeps the graviton alive. But nobody is actively looking for it. The enery levels, as you said, are out of this world, even for the lowest of the widely different predictions. And, akaik, I may not be up-to-date, the theorist still haven't solved the self interaction paradox.

I had one physics professor say that the only thing we know about the graviton is that it is spin 2. That's ultimately because the metric of GR is a 2-tensor.

But the *official* names are still 'the Earth' and 'the Moon' in spite of what Scifi fans would prefer.

Who ‘officially’ decides ?

 

[Polymath257]

Who ‘officially’ decides ?

The International Astronomical Union:

International Astronomical Union | IAU

This is the same organization that gives official names to things like asteroids, comets, as well as things like craters, mountains, etc on other planets.

and Pluto is too small to carry the 'weight ' of a planet

 

[Thief]

so yeah...
your weight would be different as you stand unto one surface...….Earth
as compared to another surface.....the Moon

but your mass remains the same

Terra? In SciFi stories, people from earth are often called "Terrains".

Sounds better than Earthers, IMO. Or, Dirtworms. Ha!

 

[Bob the Unbeliever]

It's a very heavy topic.

And if you consider the Sun? Deep, too.

By what official authority?
Afaik the "official" names by the International Astronomical Union are Terra and Luna.
(And Pluto is not a planet. Get over it.)

Yup. hard to have New Terry (Ilus) unless we have the old Terra first.

True. But proper nouns shouldn't really have "the" in front of them. If they're the names, it should only be Earth and Moon, without the "the".

 

[Ouroboros]

Sure. He's just a dog!

Ya inyalawdas.

Look at the website I posted. Those are definitely NOT the official names.

You just made an enemy for life!

Agreed, but even the IAU seems to be inconsistent on this one: International Astronomical Union | IAU

 

[Heyo]

I stand corrected - and confused. The naming conventions are otherwise strictly mythological so that earth and moon stand out. (And have no unambiguous names as all local names are recognized.)

 

[Milton Platt]

Is there a well on both sides?

"Both sides"? The earth is a sphere. You are seeing a two dimensional representation of a three dimensional space. You have to use your imagination a bit.
