I’m slow, how is the sleep of light instantaneous? I thought light can only travel at… we’ll… the speed of light.

Take the andromeda galaxy for example, It’s 2.5 million light years away so I thought light takes 2.5 million years to travel to us.

Even if we could travel at the speed of light wouldn’t it take 2.5 million years to get there?
