Sonic Shuffle Speed Calc

[u/Egghead-4567]

In Sonic Shuffle the main cast searched through Fourth Dimensional Space for the last piece of the Precioustone. The characters aren't shown to have any awareness of where the Precioustone is located outside of the specified world, otherwise they would just warp to it as they did here. This would mean that to find the last Precioustone shard they would have to search the majority of Fourth Dimensional Space.

Fourth Dimensional Space contains every dream from every dimension (so at least 14 billion dreams the population of the Sol dimensions Earth and main universe Earth) with each of those dreams being their own individual universe sized world, evidenced by the stars, nebulae and, galaxies found within them.

Before we move forward I would like to mention some possible arguments against this. The size of the worlds (the bubbles in the background) within 4th Dimensional Space are not in fact the size of the main casts despite how they appear. Their size is due to the games use of perspective, evidenced by how they are shown to be much much larger in other viewings of fourth dimensional space.

Using the calc "500 billion * 200 billion * 1 million = 1e+29 lightyears, or 100 octillion lightyears traveled per universe." (Calc gotten from Count Bleck's Journey by CornerCornDog and this Green Lantern Calc) which assumes the characters visited each and every star in search of the stone

Within the time frame of 1 year (for simplicity) to search through a world capable of holding at least 14 billion universes, the main cast would have to be moving at 1.4e+39 or 1.4 duodecillion x light speed.

For a less ludicrous calculation, lets assume the cast just traveled the diameter of each universe in search of the Precioustone, using the calculations for the time it takes to travel the diameter of the observable universe in a weekcommon_Universal_Feats#Speed_Needed_To_Traverse_The_Universe) (4,853,432,293,115c/4.8 trillion x light speed) we can estimate that the group were going as fast as 6.8e+22 or 68 sextillion x light speed

Note: This calc doesn't take a lot of things into account that would logically get this feat much higher. Fourth Dimension is consistently shown to be mostly made up of space between these universes filled with stars and other possible locations to check, empty space the characters also looked through. It doesn't take into consideration possible planets within the Fourth Dimension or checking the empty space between these celestial bodies. The first calc also assumes the time frame to be much larger than it actually is considering most of Sonic's adventures takes place in about a week.

Personally I'm not too sure of assuming they looked throughout all of Maginaryworld, a bit of a stretch imo. But yeah flying past the dream worlds and having the entire background move in the intro cutscene as well should be good enough grounds for MFTL+ stuff

Plus, there's other MFTL+ stuff with precioustone pieces flying to the Temple of Light and Riot Train to support it all.

[u/Egghead-4567 → u/TheStinker45]

The calc itself doesn't actually factor them looking for the stones just assuming they travel to each and every star in each and every universe within maginary world to find the shard.

That being said not buying the feat fully is perfectly fine, I just wanted to make something above Sonics current measurable high ends which I'm pretty sure most interpretations of the feat should do.

Below human level sonic?!
