As close as the largest observatories with state-of-the-art instruments of
the greatest precision have been able to measure, the answer is virtually
indistinguishable from eleven (11.000).
One mile is equal to 0.0000000000001701114 light years or 1/5878500794185th of a light year.
4 light years is equal to 2.35139993 × 1013 miles
Yes, a redshift of 5 does equal to a light travel distance of 12.5 billion years.
A Light-Year is a measure of DISTANCE, not TIME. A light-year is how far light can travel in one year. Light travels at 186,000 miles per second, or a little faster than 11 million miles per minute. In metric terms, the speed of light is a tad less than 300,000 km/sec. 1 light year is approximately 5.9 trillion miles, 20.5 light years would therefore be 20.5 times 5.9 trillion miles or about 120 trillion miles. traveling at 100,000 mph it would take about 137,000 years to travel the distance.
Yes, a redshift of 3.25 does equal to a light travel distance of nearly 12 billion years (i.e. 11.7 billion years).
Yes, a redshift of 2.18 does equal to a light travel distance of nearly 11 billion years (i.e. 10.7 billion years).
11 light years = 1.04065812 × 1014 kilometres
3.26 light years = 1.91639094 × 1013 miles
Yes, 13.7 billion light years is equal to 130 sextillion kilometers.
One mile is equal to 0.0000000000001701114 light years or 1/5878500794185th of a light year.
2.3 million light years is 13,500,341,279,999,999,868,928 miles.
4 light years is equal to 2.35139993 × 1013 miles
Yes, a redshift of 5 does equal to a light travel distance of 12.5 billion years.
Yes, a redshift of 8 does equal to a light travel distance of 13 billion years.
A light year is a measure of distance, not time. It is the distance light travels in a year.
A zettameter is equal to about 100,000 light-years (10^18 km).
