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.

Wait until you learn how old my sun is
fckreddit@lemmy.ml 1 month 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 1 month 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 1 month 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 month ago
At the speeds it’s moving I imagine we already lost it.
prenatal_confusion@lemmy.one 1 month ago
Wait, how do you make the laser pointer travel at the speed of light? I assume it has some mass.

I have wifi router that emits microwaves at the speed of light.
Muscar@discuss.online 1 month ago
Pffft, I have a microwave that emits microwaves at microwave speeds to microwave things.
dch82@lemmy.zip 1 month ago
This guy microwaves
Threeme2189@sh.itjust.works 1 month ago
I have lightning fast wifi at home
Etterra@lemmy.world 1 month 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.
Dyskolos@lemmy.zip 1 month ago
Impressive. The future is awesome! Can we maybe apply this to regular light too? Maybe even green light? Or purple? I’m so excited.
Karyoplasma@discuss.tchncs.de 1 month ago
If you go from green to purple, the light gets more excited too.
Dyskolos@lemmy.zip 1 month ago

Evil_Shrubbery@lemm.ee 1 month 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.
Dyskolos@lemmy.zip 1 month ago
Ohhhh right. My bad Sorry…
Eheran@lemmy.world 1 month ago
Is purple actually a light color?
skulblaka@sh.itjust.works 1 month ago
No, but violet is, and that’s pretty close.
andrew_bidlaw@sh.itjust.works 1 month ago
Accourding to the Gell-Mann amnesia effect, the same people also write about politics, environment and society.
DragonTypeWyvern@midwest.social 1 month ago
That sounds neat, I won’t look it up
andrew_bidlaw@sh.itjust.works 1 month 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 1 month ago
Yeah, they probably have it all figured out.
10_0@lemmy.ml 1 month ago
I would hope so
chiliedogg@lemmy.world 1 month ago
I’d be more impressed if they didn’t.
SendMePhotos@lemmy.world 1 month ago
Is there a way to not?
Edge004@lemm.ee 1 month ago
The medium that the laser goes through could slow it down, but it would still be insanely fast.
Etterra@lemmy.world 1 month ago
Sorta, but it’s a pain in the ass.
Agent641@lemmy.world 1 month ago
Just dont.
julianh@lemm.ee 1 month ago
Wait until they see the speaker that makes noise at the speed of sound.
mindbleach@sh.itjust.works 1 month ago
Honestly I’d be more impressed by the Star Wars kind that go about thirty miles an hour.
Jolteon@lemmy.zip 1 month ago
Those aren’t lasers. They’re contained plasma projectiles.
SandmanXC@lemmy.world 1 month ago
Wake me up when I can buy a lightsaber.

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)

Meanwhile, this headline goes at the speed of clicks:-).

This picture got some much compression artifacts just in 3 days lol.

That’s the lasers working.

Is this a reference to something or just aneurism posting?
Annoyed_Crabby@monyet.cc 1 month ago
Have you not seen those Blaster from the galaxy far far away that fire laser half the speed of sound?
Infynis@midwest.social 1 month ago
Those are changed plasma bolts

Water is wet
Confused_Emus@lemmy.dbzer0.com 1 month ago
Easy there, that’s quite a can of worms you’re tipping over.
CodexArcanum@lemmy.world 1 month ago
Indeed, many would argue that water can’t be wet, only things that water gets on/in.
Morphit@feddit.uk 1 month ago
luciferofastora@lemmy.zip 1 month 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 1 month ago
I can run at the speed of running, where is my headline?
Aurenkin@sh.itjust.works 1 month ago
I can run at the speed of fat
DavidGarcia@feddit.nl 1 month ago
uh ackchuyally it’s not the speed of light
EmperorHenry@discuss.tchncs.de 1 month ago
I can run at faster than the speed of sound at mach 2
Eheran@lemmy.world 1 month ago
Show me.
EmperorHenry@discuss.tchncs.de 1 month ago
There, I just did it! I was too fast for you to see.
Evil_Shrubbery@lemm.ee 1 month ago
But can it shit at the precise speed of a turbojet fan?
swordgeek@lemmy.ca 1 month ago
I’m more concerned that it looks like a laser turret from Portal.
lowleveldata@programming.dev 1 month ago
It’d be impressive if they fire it at like half the speed of light
Evil_Shrubbery@lemm.ee 1 month ago
I mean, any other non-c speed really.
Glowstick@lemmy.world 1 month 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 1 month ago
I would be especially interested in speeds larger than c 🙂
Xavienth@lemmygrad.ml 1 month ago
Well that’s pretty easy, just fire it anywhere except a vacuum.
AFC1886VCC@reddthat.com 1 month 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 1 month ago
Would you accept 10,000 times slower than the speed of light?
MonkderVierte@lemmy.ml 1 month ago
Still too fast to dodge.
Redderthanmisty@lemmygrad.ml 1 month 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 1 month ago
just shine a laser through a thing of zircon (index of refraction=1.923~2)
rimjob_rainer@discuss.tchncs.de 1 month ago
Then we could finally have Star Wars laser guns.
