Can You Push Things With Light?

You can actually push someone with light! Just point laser in someone eyes and he will move!

Your videos are so intelligent! And at the same time very down to earth, reasonable and free. I always look forward to your videos.

3:28 "Its getting lighter actually" Was that a pun?

Relativistic mass - ugh... As a physicist, I have to agree with Einstein himself who did not care for the concept of relativistic mass (which depends on the observer) and instead preferred to use the concepts of (rest) mass, (relativistic) momentum, and total energy. Mass is a convenient form of energy, and the amount of energy in an object due to its mass is invariant (it does not depend on the observer). Momentum, involves motion and must dependent on the observer. E^2 = m^2*c^4 + p^2*c^2 (where m is the "rest" mass, p is momentum, E is total energy, and c is the speed of light) is how we relate energy, mass, and momentum; and light (via photons) has momentum and energy related to its frequency (not due to any mass). Man, I feel better after getting that off my chest :)

3:30 "it's getting lighter"

Where were you during my science classes?! Another great video! 🤙🏾

Yeah I think it’s pushing it very *LIGHTLY*. 😂

I always knew this since I saw Goku pushed Frieza with Kamehameha

I love how your videos are so high quality, keep up the good work.

DOES THIS MEAN EARTH IS GETTING PUSHED AWAY FROM SUNLIGHT?

You should have used Black Light

I have wondered about this for years. Thanks for the fascinating video.

Thank you for always teaching me and stimulating my mind! We love you sooo much!!

There are actually "sunsails". Scientists try to use them for traveling in space without fuel, but they're not completely developed yet.

Immediately thought of a radiometer.

Thanks for shining some light on this mystery

Now try pushing things with dark?!

How doesn't this guy have more subscribers

I always had this question in my mind, and you conducted just the right experiment to visualise it. I love Action Lab.

Always awesome video!
