False the light year is not a unit of time it is a unit of distance true.
A cloth tape measure.
The Milky Way is approximately 100,000 light-years in diameter. This means that if you could travel at the speed of light, it would take you 100,000 years to cross from one side of the galaxy to the other.
The recession velocity of a galaxy at a distance of 200 Mpc (mega-parsecs) would depend on Hubble's Law and the rate of expansion of the universe. For a rough estimate, assuming a Hubble constant of 70 km/s/Mpc, the recession velocity would be around 14,000 km/s.
Traveling across the Milky Way galaxy at the speed of light would take approximately 100,000 years. However, with current technology, it is impossible for humans to travel at such speeds, so the actual time to traverse the galaxy would be much longer.
They are meters to measure
Measuring Lake Erie from the Canadian side would probably be in kilometers. On the US side would probably be in miles.
miles or kilometers
You can measure the distance across the room using a measuring tape, laser distance measurer, or a ruler. Simply extend the measuring tool from one end of the room to the other to get an accurate measurement.
Miles is best.
To measure the distance across Oklahoma, you could use a map alongside a ruler or a digital mapping tool like Google Maps, which provides accurate distance measurements. Alternatively, a GPS device or a measuring wheel could also be employed for precise calculations. Each method would give you a reliable measurement of the distance across the state.
Because the distance across the Milky Way would be 588,000,000,000,000,000 miles.
The Milky Way galaxy is approximately 100,000 light-years in diameter. One light-year is equivalent to about 63,240 astronomical units (AU), so the distance across the Milky Way galaxy would be around 6.32 million AU.
You would measure the distance of the door with meters because liters measure volume not length.
