Would it be possible to transmit data over light years instantly using shadows? All it would take would transmuting light from planet to another once, and once that's established just using shadows to send messages that would be instantaneous?

>> No.11695894

a shadow is just an absence of light dude

U still need that light to travel all the distance

in order for something on one end to effect the other end, it has to send a signal to you for you to move the shadow, and that is slower or equal to lightspeed

>> No.11696509

>>11695780
if you have negative mass you can travel faster than the speed of light. "mass" is really just the friction you get when you travel through the higgs field, so negative mass in a way would "speed you up".

>> No.11696532

>>11696509
Wouldn't even dipping a little bit into negative mass cause it to start accelerating inifinitely?

>> No.11696563

>>11696509
not how it works. "negative" mass would exert the same exact interaction as "positive" mass of the same magnitude

OP is an actual brainlet. The absence of light will only travel the speed of light so you would still be limited by c.

>> No.11696676

If you had a light bright enough to cast a visible shadow on the moon, the light would be intense enough to vaporize any material you put in front of it

>> No.11696680

>>11695780
How would you cast a shadow that big, and it still doesn't instantly get rid of the photons en route, if it's 8 light years away using a shadow, it'll take 8 years for the light to stop, there are still photons on the way.

>> No.11696684

>>11695780
Only way to do it would be some kind of stable wormhole. Even then it wouldn't be FTL comms, just a signal moving at c through a fold in space

>> No.11696777

It doesn't matter how fast the shadow is moving, if you cast a shadow from Alpha centauri, it will still take 4 years for your shadow message to reach the earth because it travels through light shot at the earth lmao

>> No.11696799

>>11695780
No. The receiver of the signal will have to wait for every photon sent before to reach them before they'll see a shadow. As the saying goes, if the sun were to vanish it would take 8 minutes for us to notice on Earth.

Neck yourself.

pushing a rigid stick would travel faster then the speed of light

>> No.11696887

>>11696807
Nope. "Speed of push" is less than C

YES absolutely
how much venture capital you've got? well work something out
