Jay-qu Posted August 13, 2006 Report Share Posted August 13, 2006 he was a smuggler :eek: and Brain I know the answer is much lower than you would expect, because of all the dark matter/energy but I do not know the exact figure. Quote Link to comment Share on other sites More sharing options...
TheFaithfulStone Posted August 13, 2006 Report Share Posted August 13, 2006 What percent share is of baryonic matter in structure of universe? Like 5% right? TFS Quote Link to comment Share on other sites More sharing options...
BrainForce Posted August 13, 2006 Author Report Share Posted August 13, 2006 That's right, not exact! as exact not determined till now (never can it be)question-Do gamma ray bursts are by neutron stars surrounding galaxies or by hypernovae taking place in deep space?

TheFaithfulStone Posted August 13, 2006 Report Share Posted August 13, 2006 I thought GRBs were caused by colliding neutron stars? What do you call a galaxy sterilizing cosmic event? :eek_big: TFS Quote Link to comment Share on other sites More sharing options...
ronthepon Posted August 13, 2006 Report Share Posted August 13, 2006 And I had heard something about gamma ray bursts and their connection with primordial black holes. Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted August 13, 2006 Report Share Posted August 13, 2006 Gamma rays can come from supernova do they not? never heard of a hypernova.. is that even more ultimate :lol: Quote Link to comment Share on other sites More sharing options...
BrainForce Posted August 14, 2006 Author Report Share Posted August 14, 2006 Ronthepon have heard somewhat right,The recent discoveries suggest that GRB's aren't caused by collision or explosion of neutron stars surrounding the galaxies,as explosions are now found to be coming from deep space. Hypernova is phenomena related with black holes those of very starting of universe.When in a galaxy (generally irregular galaxy) ,birth of a very big star takes place,it tends to spend all of it's energy in just a million year or so. After that it develops into a black hole which sends its enormous energy in the form of two perpendicular beams of gamma rays.What do you call a galaxy sterilizing cosmic event?It is a Gamma ray burst ( but rarely in galaxies of proper shape) The quasar which appears to be dynamically dominated by a magnetic field internally anchored to its central, rotating supermassive compact object ,is called what? This might be one of the easiest. Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted August 17, 2006 Report Share Posted August 17, 2006 I dont know how thats easy.. a c-m-quasar :hyper: Quote Link to comment Share on other sites More sharing options...
BrainForce Posted August 17, 2006 Author Report Share Posted August 17, 2006 Ha!:cup: That's MECO or Magnetospheric Eternally Collapsing Object So,U obviously like quizzing and is this thread (might not).I have got a new Apple Problem- Give examples of some sattelites which retrograde and have a tendency to crash into mother planet. This is far diverse from core cosmology and do come in planetary sciences. Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted August 17, 2006 Report Share Posted August 17, 2006 I dont know what you mean by mother planet, but I beleive there are some moons of uranus that retrograde.. or was it uranus itself.. :cup: im doing this without google Quote Link to comment Share on other sites More sharing options...
cwes99_03 Posted August 17, 2006 Report Share Posted August 17, 2006 Retrograde motion refers to the appearance of an object in the sky to move backwards instead of forwards in it's rotation around an object (say like the earth) when in fact the object is not revolving around the object in question. Thus 1000 years ago it was believed that the earth was the center of the galaxy and that certain stars (now known as planets) had the ability to change direction and move backwards along their orbital path around the earth for short bits of time every couple of years. This is actually caused by the earth's orbit lapping the orbit of these other planets (or being lapped in the case of mars and venus).I'm unaware of actual retrograde motion being possible for a satellite of a planet and it's parent planet.

BrainForce Posted August 19, 2006 Author Report Share Posted August 19, 2006 It's James Webb space telescope .It's laumch is to be proposed in 2010 and will be in orbit three months after its launch. What caused Giant planets to incline ? Does this concept differ from that of small planets.U may get it in the first glance. Quote Link to comment Share on other sites More sharing options...
BrainForce Posted August 19, 2006 Author Report Share Posted August 19, 2006 Oh! my god u are going too much scientific about it.Just concentrate on my second statement of question u will have answer surely. Clue- our Moon isn't that one. Mother planet is planet around which that sattelite is revolving.Retrograding is revolving in opposite direction (like west to east instead of east to west.)So, try again.

Jay-qu Posted August 19, 2006 Report Share Posted August 19, 2006 isnt retrograding just spinning in the opposite direction to its orbital direction, ie instead of clockwise orbit with clockwise spin, it has clockwise orbit and counter-clockwise spin.

BrainForce Posted August 19, 2006 Author Report Share Posted August 19, 2006 Yes! I am saying about that only.Those sattelites which do this i want. Quote Link to comment Share on other sites More sharing options...
cwes99_03 Posted August 19, 2006 Report Share Posted August 19, 2006 Okay, I peaked, Phoebe is in retrograde spin around Saturn. Venus is also in retrograde spin around the sun. What is the next deep space telescope to be placed in orbit and when is it currently scheduled for deployment? Quote Link to comment Share on other sites More sharing options...
BrainForce Posted September 9, 2006 Author Report Share Posted September 9, 2006 YA! I AM BACK! It's James Webb space telescope .It's launch is to be proposed in 2010 and will be in orbit three months after its launch. What caused Giant planets to incline ? Does this concept differ from that of small planets.U may get it in the first glance. Quote Link to comment Share on other sites More sharing options...
