    Very Simple Math problem!!!!!!!!

    im really puzzeled about this, taking time dilation into account how long would it take to travel 1100 light years? if there is a super genius among this forum please come forward.

    It depends on how fast you are traveling.

    According to someone not making the trip, its will take a time of t=d/v

    For the person making the trip it will take:

    \(T=t\sqrt{1-\frac{v^2}{c^2}}\)

    where t is the time it took according to the person not making the trip and c is the speed of light.

    So for example, if v = half the speed of light (0.5c), then t= 2200 years and T= 1905 years.

    light speed is 186000 miles a second you need to re do your math taking time dilation into account as well.

    It's also known as c.

    You need to learn to read.

    It is also 299792.458 km/sec or 1 lightsecond/sec. It can also be expressed as 1 lightyear/year.
    That's what the second equation does. It factors in the time dilation for an object moving at 0.5 c (or 93000 miles/sec)
