    So.. if I have 1 billion sun, that 6.5 cm square of an object will be pushed (or weighed) by an additional 1 pound? 1 trillion becomes 1000 pounds? So theoretically, if I found an object that emits light at the power (energy) of 1 trillion sun, I could knock things off easily Maybe a neutron star? Can I rip space dimension using extremely powered light? :o

    for yall wondering well basicly the light is reflecting on your arm and not on the bit of the object so that is how it is a shadow and a shadow is the object litterly so a shadow weighs the weight of the object so how heavy a rock is ect a shadow is nothing well thats what i think atlest edit: and yes i commented on a vide in 2012 when im in 2021

    If light was slower than it is. Say that there was a book infront of me. If someone placed the book on a table infront of me but light was really slow so I couldn't see it there. If I went to touch the table, would I feel the book? As the matter would be there but I just can't see it as the light hasn't got to my eyes yet. So it would be like it was invisible?

    I have not watched the video yet, but I always thought that a shadow was supposed to make the object lighter since you are only obstructing the light. If I remember correctly light are waves so disrupting it would make the object lighter, right?

    Here, let me answer the titles question. It weighs negative number to the surrounding light pressing on the wall. Althou photons have next to no mass, they still do. and for every light particle that is hit by the hand, is subtracted from the shadow.
