Tier 4B Solar System Level

[Lawfair]

I was wondering if someone could explain why level 4B solar system level exists? In our solar system the sun accounts for 99.9986% of the total mass of the solar system. Additionally the lowest possible theoretical mass for a star is still two orders of magnitude greater than the mass of the largest known exoplanets or the theoretical boundary mass for brown dwarves and planets. As a result someone who is Tier 4C is actually more powerful/stronger than someone who is Tier 4B if the solar system in question is ours.

I might suggest that a better way to deal with this level of power would be: Brown Dwarf Level

Main Sequence Dwarf Level (maybe dividing into Red Dwarf Level, Yellow Dwarf Level and Blue Dwarf Level)

Giant Level

Super Giant Level

Hyper Giant Level

Star Cluster Level

Planets don't add anything of value once you are at stars.

Tl;dr taking into account the inverse square law the energy required to overcome Neptune's GBE with an omnidirectional blast starting from the sun (baseline 4-B) is way higher than the amount needed to overcome the Sun's GBE (Baseline 4-C) or Rigel A's (Baseline High 4-C)

 

[ShadowWarrior1999]

Brown dwarfs are High 5-A.

Also a 4-B attack would at least reach Neptune. It isn't just about the mass of the objects but the space in between them that's being covered.

I don't think you guys understand what gravitational binding energy is, and I think you've inverted the inverse square law as well. GBE is the energy needed to overcome static equilibrium, you seem to be thinking of orbital kinetic energy (OKE), which is typically an order of magnitude greater than GBE, although they aren't related. Anyway the GBE of the sun is eight orders of magnitude greater than that of Neptune and seven orders greater than that of Jupiter the planet with the highest GBE. What tends to matter here isn't GBE or OKE but rather mass/energy equivalence in order to totally annihilate a given mass. If you can release the 10^47 J needed to destroy the sun, the inverse square law won't reduce the energy of your blast if you shoot Neptune from the sun. Even if you are using a high yield projectile, as opposed to an energy blast, the vacuum of space won't diminish the attack potency, by leaching energy, so yes it really is the case that mass is king in this discussion. Hell destroying the primary star by itself destroys the rest of the solar system.

If you can release the 10^47 J needed to destroy the sun, the inverse square law won't reduce the energy of your blast if you shoot Neptune from the sun.

The thing with the inverse square law is that while the energy sphere does, in total, have 10^47 joules of energy. But by the time it reaches Neptune that's distrusted over an area of 6.25 × 10^25 square meters. For reference Neptune's frontal surface area, which is the part that would be exposed to the blast, is a mere 9.3 x 10^14 square meters in comparison. That means Neptune is exposed to a mere 0.000000001488% of the total blast.

Which is why Solar System busting is much higher, since you need to maintain enough energy density of a huge distance accomplish the feat. Here's a more scientific site going over it

Here is why I don't like the way this is being done. Using the expanding spherical blast method as described it would require 10^52 J to accomplish, and 99.999999999999999999% of the energy would be wasted (although it would be able to take out the planets of the Proxima and ╬▒-Centauri systems as well). Sure it's an impressive feat, but it is supper inefficient, given that it's within an order of magnitude of the energy necessary to overcome the GBE of the Milkyway, and seven orders of magnitude of the energy necessary to just atomize the Milkyway. And as I have previously stated taking out the star is catastrophic for the rest of the solar system, not everything in the system will be immediately destroyed, but inner planets probably would and outer planets and other objects will be violently scattered losing at least some mass. Nothing living will survive the loss of the star. Plus there are cosmic level characters who don't have energy blast capabilities, and couldn't accomplish the feat as described but could still take out galaxies or galactic clusters.

That's ultimately how the site decided to tier stuff. Plus destroying a galaxy in one shot is more than enough to qualify for a 3-C rating on this site due to the same distance standards.
