how far u can travel at the speed of light in a year
Infrared light can travel through a vacuum and is limited by the strength of the source and the sensitivity of the detector. In space, infrared light from distant stars and galaxies can travel vast distances, enabling astronomers to view objects billions of light years away. On Earth, atmospheric absorption limits how far infrared light can travel.
Light travels about 300 attometers in one yoctosecond.
88,179,380,597,754.15 miles
