Ultimate cosmology quiz

[BrainForce]

Brain, are you talking about our solar system? i think that would be the astroid belt yeah?

 

What is the name of a large (1,000 times larger than the largest galaxy we see) gravitational lump in the universe whose nature is hidden by the milky way?

 

:) Sorry,this is neither asteroid nor kuiper belt.It is oort cloud Jay got it right!

 

Well.your question's answer i think is black hole or a quasar.

[Tarantism]

sorry BrainFarce, but that is incorrect. the question has been up there for a little while now so ill answer it:

 

the correct answer is the Great Attractor.

 

click on the link for more info, its quite neat. :eek2:

 

An exponentially expanding universe with no matter in it is called what?

a waste of space?

[BrainForce]

I think its steady state universe,its a guess i am not getting it right.

[ronthepon]

a waste of space?

I second to that.

[Qfwfq]

I think its steady state universe

No, if it's expanding it isn't steady state...

[TheBigDog]

No, if it's expanding it isn't steady state...

Unless the expansion is localized, and the universe extends beyond what we can detect at this time as expanding. Pure speculation, but no theory is complete at this point. And it may be that all are unprovable.

Let Tarantism announce its answer as nobody has answered yet.

I should ask an Apple problem-

To which part of solar system do sedna belong?(please answer on the spot -without googling)

[Tarantism]

a waste of space?

Sedna is a Kuiper belt object :)

 

So is this an astronomy quiz or cosmology :) I dont really mind either way, its a cool idea!

 

What is the roche limit?

[BrainForce]

:friday: Do cosmology not related to astronomy?Ok everyone is right .

well your question is very good & i spent my 1hr.in composing the answer.:eek2:

Here it is-

The Roche limit, sometimes referred to as the Roche radius, is the distance within which a celestial body held together only by its own gravity will disintegrate due to a second celestial body's tidal forces exceeding the first body's gravitational self-attraction. Inside the Roche limit, orbiting material will tend to disperse and form rings, while outside the limit, material will tend to coalesce.

 

If sun becomes a black hole,how would the earth be effected?

Also tell the reason for ur answer.

[Jay-qu]

very nice definition Brain :friday:

 

If the sun where collapsed to a black hole, of the same mass our orbit would be unchanged, but we would receive no light or heat from it, maybe some x-rays from in falling matter.. so earth would freeze and be dark

[BrainForce]

I also told u to tell reason for ur answer.

Well,ur answer is brilliant of course as earth doesn't come inside swarzchild radius of sun there will be no effect on earthif sun being of same mass becomes black hole.

Which scientist determined that crab nebula is polarized?

[Jay-qu]

I wouldnt have a clue without first consulting some other source.. would you like to give us the explanation?

 

While we wait for that, here is another question:

What is the definition of the distance measure of 1 parsec?

[BrainForce]

One parsec is the distance from the Earth to a star that has a parallax of 1 arcsecond.It is nearly 3.26 light years in length.

 

Clue to my question-

 

" home of comets"

[BrainForce]

Oh! :hihi:

It's Jan Oort

Are u all losing interest in this thread or u finding this quiz too easy & boring.

 

Ok,My question is-

What percent share is of baryonic matter in structure of universe?

 

This might be quite easy one.

[Tarantism]

question: what did han solo do before he joined the rebellion...:eek:
