This Image from Hubble Telescope Is Absolutely Mind Blowing

Not 80 light years, but 80 million years pre-solar system.

Meant 80M LY, sorry.  Left out the M.  Typing is not my forte.  Cats all over the keyboard, LOL!  I am endlessly editing and miss some.

Wait, why did you say "pre-solar" system?  Think about that.

[Unbeliever]

Because the hypernova happened 80 million years before the solar system formed - not 80 million light years away.

OK, yes 4.571 billion years (age of solar system) + 80 million.  I'm not sure what you are getting at.  Why the 80MYA/LY ago? 

[Unbeliever]

Not light years, just years. Why? Because that's when it happened.

The video explains it pretty well, and it's less than 10 minutes long.

A Light Year is a year of light travel.  What are you saying I'm missing?  Do you mean 80M Earth years?

OK, start again.  Are the 80MY "light years" or "Earth orbits"?  And what does the 80MY represent to you, time or distance?

[Unbeliever]

It's time, not distance.

[Cavebear]

It's time, not distance.

So you mean Earth orbits then.  Why is 80M Earth orbits important?

[Unbeliever]

Well, because that's when the hypernova happened. Of course, at the time there were no "Earth orbits" since there wasn't yet an Earth.


This is starting to sound like "who's on first."

Not 80 light years, but 80 million years pre-solar system.

Pre-solar system, so over 4.5 billion years ago.

Cavebear ... some of my days are like that ;-)  Can't quite get it together.

My thoughts exactly.  I Don't Know - 3rd Base!

I think you are trying to describe a hypernova that occured 80 LY away that caused the solar system to contract the gases from a cloud and formed Sol 4.5 B Earth orbit time ago (not that Earth existed then).  Getting that right so far?  Then the Earth and many planetoids were formed, some of which joined by gravity to create the current solar system and asteriods under the influence of Jupiter and Saturn, etc, etc, etc.

And I STILL don't know why 80MY means anything unless it was Light Years and you haven't said why THAT means anything and I'm damn well running out of patience...

So you better put some plain facts on the table.

[Unbeliever]

OK! LOL

Eighty million years before the solar system was formed, two neutron stars collided, creating and then spewing large amounts of heavy elements into the surrounding space. Some portion of those heavy elements coasted through space, eventually reaching the vicinity of the then-forming solar system. Those heavy elements became infused with the pre-solar accretion disk, about a tenth the mass of the moon, and became part of the planetary system that then formed. If that hypernova hadn't happened there wouldn't be nearly as much heavy elements in and on the Earth for us to be made from.

[Unbeliever]

This had nothing to do with the collapse of the pre-solar nebula, by the way. That was something different.

[Unbeliever]

The only place light years comes into it is that the neutron star collision happened a thousand light years away from the location of the yet-to-be solar system.

Already denying liability ...;-)

As I understand it, during solar system formation/star formation ... it gets expelled from the mother nebula.  We aren't in the same relative position as back then.
