Shining The World's Most Powerful Laser At The Moon!

Summary by Krater

The video explores the effects of shining lasers of increasing power on the Moon and Earth, ranging from a 3W handheld laser up to 40,000 yottawatts, using simulation software inspired by Randall Munroe's book What If?.

From the video

Answers: What would happen if you shone the world's most powerful laser at the moon?

• High-power lasers
• Astrophysics simulation
• Moon and Earth laser effects

What it concludes

• A 3W laser is not visible from the surface of the moon and causes no effect.
• A 1 MW laser has no effect on the moon.
• A confinement beam of 0.004 yottawatts heats the moon and warms its surface temperature to 20 degrees Celsius.
• A confinement beam of 4 yottawatts pushes the moon away and turns its surface into plasma.
• A confinement beam of 40,000 yottawatts completely obliterates the Earth into a dead rock and eventually vaporizes it.
• Shining a 40,000 yottawatt laser at the Sun does not cause any rise in its temperature.
