I have a dollar store laser pointer than can also travel at the speed of light
I can whistle at the speed of sound

Pssh, I have a 30 year old flashlight that can do the same.
dandu3@lemmy.world 2 years ago
Wait until you learn how old my sun is
fckreddit@lemmy.ml 2 years ago
I have a kerosene lantern that does the same.

The laser pointer can travel the light of speed? If you turn it on, does the laser not come out of the laser pointer?
OneWomanCreamTeam@sh.itjust.works 2 years ago
The laser and the laser pointer are both traveling away from each other at the speed of light, so from the pointer’s perspective the laser is traveling at twice the speed of light.
Akasazh@feddit.nl 2 years ago
That’s impressive. Having a non-photon mass traveling at the speed of light would break our understanding of physics. Get that laser pointer to the lab ASAP
Ziglin@lemmy.world 1 year ago
At the speeds it’s moving I imagine we already lost it.
prenatal_confusion@lemmy.one 1 year ago
Wait, how do you make the laser pointer travel at the speed of light? I assume it has some mass.

Who allowed them to sell the military equipment??

I have wifi router that emits microwaves at the speed of light.
Muscar@discuss.online 2 years ago
Pffft, I have a microwave that emits microwaves at microwave speeds to microwave things.
dch82@lemmy.zip 2 years ago
This guy microwaves
Threeme2189@sh.itjust.works 2 years ago
I have lightning fast wifi at home
Etterra@lemmy.world 2 years ago
Elections are slower than light waves so technically you have a slow, shitty router, but at least it can electrocute people so that’s something.

If you go from green to purple, the light gets more excited too.
Evil_Shrubbery@lemm.ee 2 years ago
Well, for the green light we already have FTL tech, it was invented and perfected by the car behind you as you are waiting for the light to turn green.
Eheran@lemmy.world 1 year ago
Is purple actually a light color?
skulblaka@sh.itjust.works 1 year ago
No, but violet is, and that’s pretty close.
andrew_bidlaw@sh.itjust.works 2 years ago
Accourding to the Gell-Mann amnesia effect, the same people also write about politics, environment and society.
DragonTypeWyvern@midwest.social 2 years ago
That sounds neat, I won’t look it up
andrew_bidlaw@sh.itjust.works 2 years ago
It was coined by Michael Crichton, you know, the man behind the Jurassic Park. Big Dino man can’t lie. And if they lie they are instantly forgiven.
Morphit@feddit.uk 2 years ago
Yeah, they probably have it all figured out.
10_0@lemmy.ml 2 years ago
I would hope so
chiliedogg@lemmy.world 2 years ago
I’d be more impressed if they didn’t.
SendMePhotos@lemmy.world 2 years ago
Is there a way to not?
Edge004@lemm.ee 2 years ago
The medium that the laser goes through could slow it down, but it would still be insanely fast.
Etterra@lemmy.world 2 years ago
Sorta, but it’s a pain in the ass.
Agent641@lemmy.world 2 years ago
Just dont.
julianh@lemm.ee 2 years ago
Wait until they see the speaker that makes noise at the speed of sound.
mindbleach@sh.itjust.works 2 years ago
Honestly I’d be more impressed by the Star Wars kind that go about thirty miles an hour.
Jolteon@lemmy.zip 2 years ago
Those aren’t lasers. They’re contained plasma projectiles.
SandmanXC@lemmy.world 2 years ago
Wake me up when I can buy a lightsaber.
shasta@lemm.ee 2 years ago
Sweet dreams
RandomVideos@programming.dev 2 years ago
There was an auction that starts at the price of 69420 USD and started on the 1st of april of 2022
(The lightsaber is real, selling an extremely dangerous weapon was the joke)
OpenStars@discuss.online 2 years ago
Meanwhile, this headline goes at the speed of clicks:-).
cheddar@programming.dev 2 years ago
This picture got some much compression artifacts just in 3 days lol.
Etterra@lemmy.world 2 years ago
That’s the lasers working.

What has science done?!

Has Science Really Gone Too Far Even as Decided to Use Even Go Want to do Look More Like?
Coldus12@reddthat.com 2 years ago
Is this a reference to something or just aneurism posting?
Annoyed_Crabby@monyet.cc 2 years ago
Have you not seen those Blaster from the galaxy far far away that fire laser half the speed of sound?
Infynis@midwest.social 2 years ago
Those are changed plasma bolts
cmgvd3lw@discuss.tchncs.de 2 years ago
Water is wet
Confused_Emus@lemmy.dbzer0.com 2 years ago
Easy there, that’s quite a can of worms you’re tipping over.
CodexArcanum@lemmy.world 2 years ago
Indeed, many would argue that water can’t be wet, only things that water gets on/in.
Morphit@feddit.uk 2 years ago
luciferofastora@lemmy.zip 2 years ago
I mean, the video one makes a little more sense, as it’s about destroying things at the speed of light rather than just firing the laser.
MTK@lemmy.world 2 years ago
I can run at the speed of running, where is my headline?
Aurenkin@sh.itjust.works 2 years ago
I can run at the speed of fat
DavidGarcia@feddit.nl 2 years ago
uh ackchuyally it’s not the speed of light
EmperorHenry@discuss.tchncs.de 2 years ago
I can run at faster than the speed of sound at mach 2
Eheran@lemmy.world 1 year ago
Show me.
EmperorHenry@discuss.tchncs.de 1 year ago
There, I just did it! I was too fast for you to see.
Evil_Shrubbery@lemm.ee 2 years ago
But can it shit at the precise speed of a turbojet fan?
swordgeek@lemmy.ca 1 year ago
I’m more concerned that it looks like a laser turret from Portal.
lowleveldata@programming.dev 2 years ago
It’d be impressive if they fire it at like half the speed of light
Evil_Shrubbery@lemm.ee 2 years ago
I mean, any other non-c speed really.
Glowstick@lemmy.world 2 years ago
Actually, c is the speed of light in a vacuum, but light travels slower through a medium, like air. So lasers shot through air will actually travel slower than c.
Eril@feddit.org 2 years ago
I would be especially interested in speeds larger than c 🙂
Xavienth@lemmygrad.ml 2 years ago
Well that’s pretty easy, just fire it anywhere except a vacuum.
AFC1886VCC@reddthat.com 2 years ago
Imagine if they made it fire so slow that you could just do a dark souls dodge roll to avoid it
Catoblepas@lemmy.blahaj.zone 2 years ago
Would you accept 10,000 times slower than the speed of light?
MonkderVierte@lemmy.ml 2 years ago
Still too fast to dodge.
Redderthanmisty@lemmygrad.ml 2 years ago
Yeah, but this requires that the light be travelling through a dense medium to slow down. It still speeds up again when travelling through air or vacuum
Jumuta@sh.itjust.works 2 years ago
just shine a laser through a thing of zircon (index of refraction=1.923~2)
rimjob_rainer@discuss.tchncs.de 2 years ago
Then we could finally have Star Wars laser guns.
