I did a recalc of Nidavellir's size here: https://vsbattles.fandom.com/wiki/User_blog:Revan_Laha/Nidavellir%27s_size_(with_proper_pixel_scaling)
Crimson Azoth calculated the size of the beam here: https://vsbattles.fandom.com/wiki/User_blog:Crimson_Azoth/How_big_is_Nidavallir%3F_-_Marvel_Cinematic_Universe
The problem he did is using the beam to scale the diameter, because it's so thin
Dino W's original calc is here: https://vsbattles.fandom.com/wiki/User_blog:Dino_W/Thor_tanks_a_neutron_star_recalc
As you can see only the radius of the star has increased to 1.9099 times of the original, that means the energy will increase by 3.6477 times of the original.
Therefore new value= 3.6477*0.85556=3.121 teratons.
Thor tanks Nidavellir's energy=3.121 teratons of TNT (Small Country level)
