This all-encompassing visualization is made by Dr. James O’Donoghue, who works as a planetary scientist at JAXA (Japanese Space Agency). Before that, he contributed to NASA’s Goddard Space Flight Center.
This extra-ordinary real-time visualization starts with mother earth and depicts how swiftly the light travels in space (300,000 km/sec or 186,000 miles/sec). However, as soon as the other objects of space (moon, planets, sun) are visualized, it becomes difficult to fathom all of it
It is amazing how clearly the audiovisual aids explain such difficult concepts.
