to try and help someone visualize such a HUGE number,
id put it this way,
if i were to stack a whole bunch of 2mm thick pennies on top of one another, 2e64 pennies* would give me a pile of pennies beyond the moon (400 000 km away) and the sun (150 million km away), which would in fact reach the nearest star "Proxima Centauri" (which is about 4 light years away). so obviously, e99 would be a
little further than that
1km = 3280feet
* (i use 64 instead of 99 because 2e64 is actually a documented distance i found)
does that make sense?
