Suppose you had a spaceship so fast that you could make a roundtrip journey of 1 million light-years (in Earth's reference frame) in just 50 years of ship time. If you left in the year 2030, you would return to Earth?

i) A million years from now
ii) The year 2130
iii) The year 2080

Option i) A million years from now

Explanation:

According to Earth's reference time frame, the spaceship will go a roundtrip journey in 1 million light-years.

So if the spaceship left the earth in year 2030, it will return to the earth a million years latter.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
