# How many years would it take to cross the galaxy at warp factor 9?

show the math

hint: warp factor 9 is 2^9 times the speed of light.

morningfox got it right. It takes light 100,000 years to cross the galaxy. going 512 times light speed, it would take 100,000yrs /512 = 195 years.

What far too many people fail to grasp is that Star Trek used warp speeds in each episode as was needed by that story.

In That Which Survives, the Enterprise covered 990 light years within a day and a half. Thus, it is clear that high warp speeds are faster than your putative formula would allow, thus that formula must be very wrong.

SInce it is fiction, you can make the journey any length you want in order to serve the plot of your story.

Remember that good fiction is about character development, scene setting, dialog that rises above innanity, maintaining reader or viewer interest through an interesting storyline, and for written fiction using good grammar with an interesting vocabulary.

Warp 9 is 1,516 times the speed of light.

The galaxy is estimated to have a diameter of 105,700 light years.

So to travel 105,700 light years at 1,516 times the speed of light it would take 69.73 years.

2^9 = 512 light speed. So it would take 195 years. I have no idea how time dilation works at warp speeds. And also, is this for TOS or TNG?

At that speed you could travel 10 light years in 51 minutes. The milky way galaxy is approximately 100000 light years across so it would take about 8 or 9 hours

It would take at least one.
