Black holes

[Gaf The Horse With Tears]

Our sun is not massive enough for a supernova or a black hole.... it will most likely turn into a low powered red giant, and then burn out....

First it will use up most it's Hydrogen and it will collapse into it's own gravity well... this will heat it up again and burn whats left of it's hydrogen.. during this time it will swell in the Red Giant phase.... When the hydrogen is completely gone.... it will start burning it's helium... which will cause it to shrink and swell a few times... finally it will slowly spend it's last days as a White Dwarf about the same size as Earth. Some day, way way way in the future... it will completely cool into a Black Dwarf. (Black Dwarfs are only a theory, the calculated time for a white dwarf to cool into a Black Dwarf is longer the the Universe has existed.)

Also, on the odd chance that .4 solar masses is added to the sun during it's White Dwarf stage it could explode in a Type La SuperNova.

I find this so said, but true. Its sad to think of something as wonderful/beautiful as the sun, will one day drift through space as a cold, burned out cinder.

Not for a very long time...

When it does reach red giant phase it will encompass most of the inner planets (Mercury, Venus, Earth, and perhaps Mars) as well.

Thats cool though... The Sun's luminosity is going to go through the roof before then... like within the next Billion years... and boil our oceans into a vapor state... run away green house affect like Venus until Sol finally swells up to burn us away.

You want to see the earth in a few million years..... have a look at Venus.... beaches on the seas of boiling lead....

The clock is ticking.... we need to get to work on the FTL drive NOW.

[phee]

Indeed.....

This was mentioned earlier of course, but the term Black Hole is actually sort of in acurrate.... the "shape" of a singularity is actually closer to a sphere or elipse.... The "Hole" part of it is more of how it seems to effect space-time around it.

(Told you I would get boring)

[Gaf The Horse With Tears]

you forgot the fountains at the "poles".

[Guest Megalicious]

... When the hydrogen is completely gone.... it will start burning it's helium...

OMG, I have to share.

So we are playing trivial pursuit. A 1 point science question. What is the second most common element in the sun (the first being H)?

You think everyone would know that.

I was blown away that someone got it wrong. DUDE, seriously. Blown the fuck away.

I remember being in like 6 grade and OBSESSED with H fusion, the plasma state of matter and WHY if they were the same charge, WHY DID THEY GET FUSED TOGETHER!?? Why didn't they repel? The sun is the reason (and water) for our very being, its so very important.

::sorry I will not rant any longer:::

[phee]

you forgot the fountains at the "poles".

Ah yes... where the said "Hawkins Radiation" emits from the strongest.... which is still barely at all, because it is the shrapnel of the atoms that the black hole has torn to shreds that had just enough velocity to escape the event horizon... which is about a billionth of the mass of the atom itself... very small.

Also, on the odd chance that .4 solar masses is added to the sun during it's White Dwarf stage it could explode in a Type La SuperNova.

Does that mean it would become a stellar BH?

(Type La? that is)

[phee]

Its funny.... from reading this thread today, I now have the Dr. Who theme stuck in my head....

[Gaf The Horse With Tears]

Does that mean it would become a stellar BH?

(Type La? that is)

No, it would look something like this for a while and slowly expand until it disapated...

Here is a trivia question for you...

1. What 3 Elements were created by the Big Bang.

[phee]

Supernovas and pulsars are the only things they know that emit tacions (FTL particals)... which is interesting because according to relativity something moving FTL would technically be going back in time..... When they first detected tacions, the people doing the calculations actually had to figure our what was going on because there calculations showed that....

[Gaf The Horse With Tears]

Tachyons have never been proven to exist. Even if they do exits... they dont, do to tachyon condinsation... and if they do... they cant transfer information to other things... which means we would never have a way of detecting them... and we still spending time looking for them...

That depends.... are you counting isotopes?

[phee]

deuterium, helium, and lithium

[Gaf The Horse With Tears]

Oh phee... can't you count to three? It's the first three elements on the Periodic table. The rest of the elements were created in stars later on. See, the explosion was so massive that every was swept away by the force of the explosion before they could bond into more complex atoms.

Hydrogen, Helium and Lithium

Damn spelling

[Guest Megalicious]

deuterium, helium, and lithium

Actually Phee is right, Deuterium is also know as "heavy Hydrogen".

[phee]

Thankyou for standing up for my science my good lady

[Gaf The Horse With Tears]

It's an isotope of Hydrogen... which is close to right... but is not it's "own" element. Hydrogen is the correct answer.

[phee]

That depends.... are you counting isotopes?

hence the question I asked earlier

[Gaf The Horse With Tears]

but you gave your answer before I could answer that question... jumping the gun buddy.

[Guest Megalicious]

It's an isotope of Hydrogen... which is close to right... but is not it's "own" element. Hydrogen is the correct answer.

If you want to get technical no (2)H is the right answer not H.
