How many Yottameters are in the universe?
The diameter of the observable universe would be approximately just 880 yottameters, points out Jessica Leber at MIT’s Technology Review — meaning if there were a bigger prefix than yotta, the entire universe would fit inside one of them.

Online unit conversion – length The length value 9.461E-15 m (meter) in words is “nine point four six one one five m (meter)”.
How fast is a light-year?
In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
How long the universe is?
The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, or 8.8×1026 metres or 2.89×1027 feet), which equals 880 yottametres.

How fast is the speed of dark?
54 meters per second
Is there such a thing as the speed of dark? In a 2013 study, scientists determined that dark matter should have a speed of 54 meters per second, or 177 feet — slow compared to the speed of light.
How long would it take a human to travel a light year?
about 37,200 human years
Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.
