The moon most likely formed that way and that didn't result. (nt) Posteritatis Apr 2013 #47

I know but the earth was composed of dense material. Spitfire of ATJ Apr 2013 #50

Or it would likely spin out of the star system. longship Apr 2013 #48

We don't know what goes on in nebulas. Just about anything is possible.... Spitfire of ATJ Apr 2013 #53

Well, still, the universe obeys the laws of nature. longship Apr 2013 #58

"its self gravity could not hold it together." Spitfire of ATJ Apr 2013 #64

Good pun, my friend. longship Apr 2013 #65

I don't believe you could have a super lightweight planet in the Goldylocks Zone. Spitfire of ATJ Apr 2013 #67

But no homogeneous matter is likely to exist in any primordial system. longship Apr 2013 #68

Okay, but keep in mind that Earth has the highest density in the solar system. Spitfire of ATJ Apr 2013 #69

No problem there. nt longship Apr 2013 #70

Just look at the Tea Party. Spitfire of ATJ Apr 2013 #72

That might be the case with 253 Mathilde sofa king Apr 2013 #71

I can picture a collection of gasses forming in a nebula liquifying, bubbling and solidifying. Spitfire of ATJ Apr 2013 #73

The smaller one's 1.4 Earth masses, which wouldn't be that bad Posteritatis Apr 2013 #45

Don't fret over not having the equation.... Spitfire of ATJ Apr 2013 #49

at 2700 light years away they may not exist anymore leftyohiolib Apr 2013 #8

That really isn't that far away to speculate that it may not exist anymore.... cbdo2007 Apr 2013 #12

A rocket traveling at light speed would take 2,700 years arcane1 Apr 2013 #14

Hahahaha, sorry. Figured my math would be off by a lot..... cbdo2007 Apr 2013 #20

The relative time on the rocket would be much less, at least arcane1 Apr 2013 #32

At the speed of light the aging rate of the rocket passengers would be 0 MillennialDem Apr 2013 #33

Correct :) arcane1 Apr 2013 #36

And since time stands still it would become a trap as there would be no way to shut it off. Spitfire of ATJ Apr 2013 #54
