how fast is this?

if someone or something had to move from one side of the universe to the other in a Zeptosecond, how fast would that be?
 
Depends on the size of the universe. Assuming the size of the observable universe that'd be about 3x10^36 times FTL.
 
A zeptosecond is 10^(-21) s.

The universe is 93 billions of light years in diameter iirc.

93 billions of years are 31.536.000.000.000.000 seconds.

Add 21 zeros because you are dividing by 10^(-21)

So it's 3,1536*10^37 unless i made a mistake somewhere.
 
Diameter of observable universe is 8.8*10^26 metres.

Zeptosecond is 10^(-21) second.

Velocity:

= [8.8*10^26] / [10^(-21)] = 8.8e47 m/s

Speed of light = 2.998e8 m/s

Therefore, that would be 2.9352902e39 times speed of light.

Travelling from one side of the universe to the other in a Zeptosecond:

= 2.9352902e39c

This one's right, I lost 3 orders of magnitudes somewhere. Probably accidentally used 93 million instead of 93 billion for the diameter of the universe.
 
well, I had an idea for an Oc that summons Lighting, but the lightning stems from one side of the universe and travels all the way to earth to strike down his enemy in a Zeptosecond, making it a dangerous ability. I thought it would be FTL+ at best lol O_o

Vitiate and Sidious travelling half-way across one galaxy over a few years was Massively FTL+ (tens of thousands of times FTL).
 
wow ... yeah I never paid attention to how large galaxy and distances are ...woah lol
 
What's the point of the lightning arriving from across the universe? It'd have sub-planck time speed if it struck from the atmosphere.

Oh, crap, I meant Low 8-C.
There is no Low 8-C.

9-A = Small Building level

8-C = Building level

High 8-C = Large Building level

Lightning bolts are 5 Gigajoules or 1.195 Tons of TNT equivalent. That'd be 8-C (Building level+).

Imagine if we had town level lightning IRL.
Astronomers have detected electric currents / lightning around supermassive black holes measuring up to 5 Zettajoules or 1.195 Teratons. That is Low 6-B (Small Country level).

Imagine this type of lightning around a kugelblitz.
