Sirius B

Sirius B evidently did go Nova 120 million years ago, it is only 8.6
light years away how could anything on earth survived such a
blast.....

Krita started 146 milj ago and ended 86 milj years ago?

Is this correct?

A nuclear weapon exploded over Hiroshima, Japan, on 6th August, 1945.
How could anything in the USA have survived such a blast.....

No.

Oh you are correct Androcles it was 65 miljon years ago
But the the Triassic–Jurassic extinction event marks the boundary
between the Triassic and Jurassic periods, 199.6 million years ago,
and is one of the major extinction events.

I do not know but i see the possibility for some doubts in carbon
dating, and also when it comes to put dates on events within
astronomy. I find it reasonably to beleive that Sirius B was cause to
the Triassic-Jurassic extinction.

That leave us with the question what star did go nova when the great
dinosaurs dissapeared.

So any Astronomer out there could tell me a nearby star that did go
Nova at the end of Cretaceous–Tertiary time 65 miljon years ago, that
was a pretty major extinction event.

I know they say it was an Asteroid and sure it can have been to.

============================================

Whoopee for you. yawn
Now prove it.
I find it reasonably to believe that bright green flying elephants lay their
eggs in black holes but I do not know and I can't prove it... and you
are not really interested. Let's prove Santa Claus comes down chimneys
instead, we can both believe that one.

Well "SCIENTISTS" tells that if Betelgeuse goes Nova and if it's
rotational axis aligned our way we would be in very difficult position
and alot of life on earth would actually threatened. It is 427
lightyears away.

Wikipedia:Betelgeuse
"Since its rotational axis is not toward the Earth, it is believed
that Betelgeuse's supernova would not cause a gamma ray burst in the
direction of Earth large enough to damage Earth's ecosystem even with
its relatively close proximity of 427 light years."

Now ALDEBARAN is only 65 millions away and i have a feeling that if it
go Nova we are ****ed,
Now you prove me wrong and you will not find it that easy.

So if you have a better bet for the great extinctions then supernovas
tell me.
I do not find it unreasonable that asteroids caused the great
"extinctions", and i do not find it unreasonable that supernovas did
it either.

I understand though that it give more comfort beleiving that they were
caused by asteroids.

==============================================

Stick around sci.physics and count the cranks. Some of them write
articles for wackypedia, the encyclopaedia any crank can write.
They like to call themselves "scientists".


Now ALDEBARAN is only 65 millions away and i have a feeling that if it
go Nova we are ****ed,
Now you prove me wrong and you will not find it that easy.

==============================================
You obviously missed my point about proof, son.
I don't have to prove you wrong, you have to prove you are
right. The burden of proof is upon the claimant.
If I say bright green flying elephants lay their eggs in black holes
it is up to me to prove it. Anyone can say anything they like but only
a fool would believe the nonsense.
Why do we require proof?
Well, if someone accuses you of a crime you can be thrown in jail,
but the law and common sense requires that you be given a fair trial
and the accuser must prove beyond a reasonable doubt that the
accusation is true.
I do not believe you.
Tough, isn't it?
I didn't swallow your silly story, so what are you going to do about it?
Show me the proof. I don't have to prove you wrong, you have to
prove you are right.
Scientists say you are wrong, is that good enough a proof for you?
I found that very easy.
Now who is ****ed?

==============================================
So if you have a better bet for the great extinctions then supernovas
tell me.
==============================================

Bet? You want a wager? Put money up?
Ok, how much money will you deposit with a lawyer (because I'll match it)
and what are the rules for deciding the outcome?
I bet you that I can do a better job of persuading people Aldeberan
will not go nova in my lifetime or yours than you can that it will, and
I bet you that you cannot prove the great extinctions were anything to
do with novae.
BTW, the plural of "nova" is "novae", not "novas". Otherwise we'd
be saying hippopotamuses instead of hippopotami.
==============================================

I do not find it unreasonable that asteroids caused the great
"extinctions", and i do not find it unreasonable that supernovas did
it either.

================================================

I do. It is very unreasonable and indeed childish to latch on to the first
thing you think of when the true answer is not known and may never be
known. If you want to be a scientist the first thing you must learn is
how to prove what you claim, or you will simply be laughed at.

================================================
I understand though that it give more comfort beleiving that they were
caused by asteroids.
================================================
Then you understand very little.

I believe it is the vast quantity of soil upset, and the layer of
increased iridium that occurs about the time of the extinction
that makes them think that. A GRB won't do that.

But whatever "Chicken Little" thing you want to want to waste
your creative thought on...

30 thousand years ago the core of our galaxy burped a few million
solar flares,
left the core of the galaxy empty. The core of our galaxy emits
millions
of times less radiation then the core of other galaxies.

On top of it the magnitude of the flare not weakens as it exist the
galactic
system through its disk but escape flare velocity builds. It moves
just
below the speed of light and the event was just spotted a few years
ago.

All the prediction for a flare passing us for a thousand years (500
years of heating just begun and 500 years of cooling period) is
found at:
www.geocities.com/gmbajszar/BreakPedalEffect.htm

This radiation is nothing more than an immense heat source
that heats up any gas in its way, where gas flares up. With the
solar rays it is hard to detect this energy other than what we
see: An instantly disappearing Norther ice cap. It was shown
that the disappearing Ozone layer actually cools the Antarctic,
though green house gasses don't build up there as a result.

So. Imagine 500 years of accelerating heat. It was determined
that since the flare passed through in 10 years a gas cloud
300 light years from the core of the galaxy, that we are 100 times
further away and the event instead of 10 years will pass us by
in 1000 years, and the heat is not as instantly heating as it
was in so close proximity to the core of the galaxy.

What we will see is that all predictions for global warming come
in outpasting growth of heat. It was thought that the northern
ice cap would disappear by 2040, but only the next year that
number quickly moved down to 2012.

It may happen just based on all the dooms day predictions online
for December 21, 2012, that a huge shiny radiation burst will hit us,
and we are only experiencing the pre-heat.

I know they say it was an Asteroid and sure it can have been to.

As the 6+ solar mass of Sirius B went red giant and eventually flashed
over into becoming the little but dense white dwarf, whereas that
entire process lost track of at least 5 solar masses, with one of
those solar mass units likely picked up by Sirius A.

There's also a darn good chance we were a whole lot closer to the
Sirius star/solar system at that time. So, the terrestrial trauma
caused by such a nearby event could very well have represented the
primary cause and subsequent demise of such large scale forms of life
which existed that that time.

What do you understand about the tidal radius holding onto various
planets and their moons?

How do you know that?

it is only 8.6 light years away

How far away was it 120 Myr ago?

how could anything on earth survived such a blast.....

http://stupendous.rit.edu/richmond/answers/snrisks.txt
gives some estimates of SN effects. The Wikipedia article
http://en.wikipedia.org/wiki/Supernova#Impact_on_Earth
seems pretty reasonable, but I haven't read it in detail, let alone
checked it.

With regard to a later post in this topic, what evidence is there
that gamma rays from supernovae are beamed?
