If somehow a supernova will be redirected to 30, 45, 60, 80, 90

If somehow a supernova will be redirected to 30, 45, 60, 80, 90 degrees cone, would the blast received be powerful than the 360 degree blast?.

and how small would a "solid hydrogen ball" (to create a small star) amount for when it's compressed... just small Gamma Ray Bursts and explosion is just enough to wipe out, say Monreal off the face of the map, (i don't have anything against Monreal, just reference for the size).

here's the supernova facts,

it's when pressure collapses and excessive gravity compresses molecules of the entire star to the smallest point possible and thus collapses.

downsizing it to be a little safer, how big or the mass of the material, or Hydrogen molecules when super compressed to the smallest point and acts like a mini supernova; "Nova" blast, also adding the Munroe effect, what size for the mass to annihilate a city the size of Monreal?

IF it were possible, then yes, just like any explosion.

The rest of your post doesn't make any sense. Supernovas and Novas are two completely different phenomena and have very specific conditions that form them. Could you elaborate or break up your questions a bit?

A white dwarf is what you are talkign about I think. I don't know how big those are for something around 1 solar mass.

oh, okay Nova...

i'm asking about "what would the size of the star to be compressed for it to be safe enough to blow a city the size of monreal"... like the size of ping-pong, bowling, tennis... something like that...

and short gamma ray burst safe enough to not damage the earth's atmosphere

Drakkith

Are you asking what size the star would need to be in order to experience a supernova that only blows up Montreal?

the6thmesseng

yeah... but not really monreal... just a reference for the size of the city.

Drakkith

You are asking about something that isn't possible. Since it cannot happen, I don't know how to calculate any estimate assuming that we could "make" it happen.

But to put the energy in perspective, a typical supernova releases about 1.2×10^44 J.
Tsar Bomba, the most energetic nuclear weapon ever detonated, released about 2.1×10^17 J.

Tsar Bomba, which had enough energy to destroy an entire city or more, is about 27 orders of magnitude less than a supernova. So about a thousand million million million million times less.

Oh... okay thanks.... any ways this thread is unofficially closed. but i have another question, im dying to get an answer; http://www.physicsforums.com/showthr...36#post3389236
