Yea, but it's no Champagne Supernova

I think 'lab grown supernova' would sound better.

// backyard supernova
// southbound supernova
// assclown supernova

Laboratory Supernova?
Could have a fun science theme.

I'm more interested in the fact that there's a legitimate science website who seems solely dedicated to laser related articles.

Great now make a rocket engine from it.

The University of Oxford has used laser beams 60,000 billion times more powerful than a laser pointer to recreate scaled supernova explosions in the laboratory as a way of investigating one of the most energetic events in the Universe.

I appreciate that the researchers are doing this, but it's troubling to me that they're diverting resources to look at this instead of finishing laser experiments that had been started but not completed in other scientific fields.

Can we please get back to finalizing research on the important stuff? Specifically, the full parameters of how far up a wall you can get a cat to go if the laser moves, where V is the velocity of the cat, P is the power of the laser pointer, S is the speed of the laser point movement and Y is the vertical height of the wall (assuming sea-level air friction and a zero-obstacle starting environment)

Big deal. I had two tabletop supernovas in one session of my homebrew Necromunda war game when Princess Unikitty tore apart two Necron Monoliths.

You know, I was never worried about the LHC creating blackholes or anything because I understand that miniature blackholes will quickly evaporate.

Miniature supernovas on the other hand??? Yeah, the would evaporate as well once the pressure is removed. But the certainly could destroy a large section of the earth when they explode.

I'm sucking up more karma than I need - so have a supernova on me.

You understand that the scale of a supernova is exactly what makes it do the nasty things it does, right?  Compressing a millionth of a milligram of matter into a tiny space is a bit difference than compressing a few dozen million earths worth of matter.

In before fusing iron.

Can you say, BOOM??
 
2014-06-17 05:12:46 PM
So what you're saying is that everyone in 5 AU takes (106)d6 fire damage?

I knew my astrophysicist should have prepared protection from heavy-metals fusion today.

So you had a rogue Squiggoth of entirely the wrong scale demolish the monoliths?

Still no cure for Oasis.

/saw them walk off a stage in Indy because someone threw a beer cup on stage
//did get a 4 minute lecture on how disrespectful American concertgoers were compared to English ones
///seen seats torn up and thrown on stage with encouragement from the band, they wouldn't know an enthusiastic audience if it concussed him.
////20 years ago and I still recall his rant. Only time I ever saw a performer shut down like that

Jim_Callahan: So what you're saying is that everyone in 5 AU takes (106)d6 fire damage?


I always wondered ... just how far immunity to fire damage goes. How hot does a fire have to be before it's not considered 'fire' damage anymore? Is there a cutoff point where 'fire' damage becomes plasma damage or some such.

I mean, imagine this scenario.

The entire planet burns to a crisp due to a massive coronal flare (or a meteor strike, or some other such epic 'fire' event that causes massive area damage).

And all that's left is people/creatures with immunity to fire.

http://www.wizards.com/default.asp?x=dnd/glossary&term=Glossary_dnd_ fi reimmunity&alpha=

"A creature with fire immunity, such as a fire giant, never takes fire damage. It has vulnerability to cold, which means it takes half again as much (+50%) damage as normal from cold, regardless of whether a saving throw is allowed, or if the save is a success or failure."

If they are capable of living on the elemental plane of fire, i think they'll be fine. Now, the positive energy plane on the other hand....

I never liked 'immunity' in the rules, I don't like to think in terms of absolutes.

I always thought it should all be damage threshold based. IE, they deduct this much from the base damage before taking damage.

So you could give the regular creatures like dragons and the like a high enough DT to protect them from earthly forms of fire. And fire elementals and the like would have a crazy high DT.

That way, you can still purge the earth with fire and kill the regular fire resistant stuff, while still allowing creatures that are basically MADE of fire to survive.
