Well I thought the time was right for some researchers to answer some interesting (to some) questions which will be added to from time to time
1 point for correct answers
Cosmicly speaking and as Spock would say FASCINATING
1 to the nearest 1% how much of the total mass of the solar system is contained in the sun?100%
2 how many times more luminous is the pistol star than the sun?25 million times more luminous
3 what are Zena Sedna and QuaoarKuyper Belt Objects or dwarf planets outside the orbit of Pluto
4 at the time of the dinosaurs say 300,000,000 years ago approx how many hours was the day on the earth?21 hours
5 the moon is gradually receding from the earth, how far is it moving away each year?3 cm
6 what is likely to be at the centre of a black/brown dwarf (a dead white dwarf)star, worth a mind boggling 3 points
7 what is Newtons law of universal gravity Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them.
8 how many seconds does it take light from the sun to reach the earth 500 seconds
9 who described laws which govern the orbits of planetsJohannas Kepler
10 what is the name of the cloud containing predominantly icy objects which surrounds the solar system and defines the cosmological boundarythe oort cloud
At the cinema to follow...which films do these quotes come from
11 you've got no arms left,yes I have, look, just a flesh wound Monty Python & the Holy Grail
12 want me to do your hair Shampoo
13 keeping the British end up sirThe Spy who loved me
14 you came in that thing? You're braver than I thought Star Wars 1V
15 food fight Animal House
16 keep away. The sow is mineThe Exorcist
17 this is Ripley, last survivor of the nostromo signing off Alien
18 the horror, the horrorApocalyps Now
19 keep your friends close, but your enemies closerGodfather part2
20 can you dig it Warriors

Though not specified, will limit my answers to four.....
17 Alien ?
10 The Milky Way galaxy ?
8 It take's the sun's light approximately 8 minutes to reach the earth, so 8 x 60 = 480 seconds.
6 A black hole comprising anti-matter ?

9 Johannes Kepler.
7 Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them.

6. I would of thought just a collection of matter coolong down and emitting minimal radiation? Its the type of matter I'm looking for, if you can decide what element is likely to be the major component, then a really interesting answer becomes apparent, you need to think of the life cycle of a normal sized star! |

6. The first black dwarf hasn't come about yet as its stage in the life-cycle of a star (when it has ceased to emit anything) exceeds the life of the universe to date.

6. The first black dwarf hasn't come about yet as its stage in the life-cycle of a star (when it has ceased to emit anything) exceeds the life of the universe to date. Not a trick question tommo, there will always be a residual radiation due to the half life of the elements present, perhaps I should call it a brown dwarf, where the emissions are there but not hot enough to be observable. The normal life cycle of a Sun type star is 10billion years, with the universe over 14billion years old there should be billions of them about,but we can't see them! Stars burn hydrogen for most of their life cycle, what happens when this fuel runs out? Regs cs |

6. Im going to take a stab at the star loses all of its hydrogen and gains so much mass that it implodes on itself therefore creating a black hole and emitting dark matter. God that hurt my brain!!
3. Dwarf planets
10. Is it the Kuiper Belt?

God that hurt my brain!! 3. Dwarf planets 10. Is it the Kuiper Belt? Impressive thinking you're assumptions are on the right track with number 6 but to assist when the hydrogen is exhausted the star starts burning the next heavier element which is helium and expands into a red giant phase due to the increased pressure, the star blows away it's outer shell which could form planet forming nebulea, the residual matter in the star is extremely dense, if the original star was approx 8 times heavier then the matter would be so dense that gravity would overcome the radiation pressure and a singularity would form. In the case of a white dwarf the density and pressure forces the atoms so close together that they can share electrons and form an element soup with helium ,carbon and other heavy elements, the heavier elements like carbon sink to the centre. As the white dwarf cools over millions of years, carbon crystallizes out of the soup under high pressures.....and what do you get.... 3 dwarf planets is correct for 1 point , I was looking for the term Kuyper belt object (KBO) Plus 0.5 for persistence 10 getting a lot warmer now bpm Regs cs |

Fair play, it is a fascinating subject i must say!
8. 490 seconds, which given how fast the speed of light is, really does reflect the vast distance from Earth to the sun!

6. 10. I think you're after the answer "The Oort Cloud" which is approx a thousand times the distance of the Kuiper Belt.
edit - error in numbering - sorry !

I'll be angry if he gives this, in view of my earlier answer of 480 seconds with workings ! AFAIC the speed of light is 186,000 miles per second, and the Sun is 93 million miles away - though I bet he'd split hairs on that one too !  |

The figures are correct but the maths is a bit out I make it 500 seconds but worth a good point bpm and a consolation 1 points for tommo Regs cs 93000000/186000=500 |

Im assuming you mean number 10 is the Oort cloud gentlemen, as that being at the centre of a black dwarf would be mighty impressive!!
I wonder how intense VY Canis Majoris would be as a
black dwarf.

Well spotted bpm it should be question 10 didn't think tommo was the error making type! Being one of the brightest super large red giant stars it will probably end up as a super super nova. (Hypernova) in quite a short time cosmicly speaking, I wouldn't want to be in that galaxy when it blows! Regs cs |
