I can whistle at the speed of sound

It'd be impressive if they fire it at like half the speed of light
- I mean, any other non-c speed really.
  
  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.
  
  I would be especially interested in speeds larger than c 🙂
  
  Well that's pretty easy, just fire it anywhere except a vacuum.
- Imagine if they made it fire so slow that you could just do a dark souls dodge roll to avoid it
- Would you accept 10,000 times slower than the speed of light?
  
  Still too fast to dodge.
  
  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
- just shine a laser through a thing of zircon (n=index of refraction=1.923~2)
  so speed of the laser in the zircon = c/n ~c/2
- Then we could finally have Star Wars laser guns.

I have a dollar store laser pointer than can also travel at the speed of light
- Pssh, I have a 30 year old flashlight that can do the same.
  
  Wait until you learn how old my sun is
  
  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?
  
  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.
- 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
  
  At the speeds it's moving I imagine we already lost it.
- Who allowed them to sell the military equipment??
- Wait, how do you make the laser pointer travel at the speed of light? I assume it has some mass.

The army trembling when I bring a mirror
- NOW YOU FUCKED UP!
  
  SUPER.
  HOT.
  
  World around
  Around the world
  World around
  Around the world

I have wifi router that emits microwaves at the speed of light.
- Pffft, I have a microwave that emits microwaves at microwave speeds to microwave things.
  
  This guy microwaves
- How many hot pockets do you need?!
  
  At least 3.50
- I have lightning fast wifi at home
  
  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.

Impressive. The future is awesome! Can we maybe apply this to regular light too? Maybe even green light? Or purple? I'm so excited.
- When you go from green to purple, the light gets more excited too.
  
  insert sensitive chuckle-magazine-guy-meme
- 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.
  
  Ohhhh right. My bad Sorry...
- Is purple actually a light color?

According to the Gell-Mann amnesia effect, the same people also write about politics, environment and society.
- That sounds neat, I won't look it up
  
  Yeah, they probably have it all figured out.
  
  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.

- I'd be more impressed if they didn't.
- Is there a way to not?
  
  The medium that the laser goes through could slow it down, but it would still be insanely fast.
  
  Just dont.
  
  Sorta, but it's a pain in the ass.

Wait until they see the speaker that makes noise at the speed of sound.

Honestly I'd be more impressed by the Star Wars kind that go about thirty miles an hour.
- Those aren't lasers. They're contained plasma projectiles.

Wake me up when I can buy a lightsaber.
- Sweet dreams
- There was an auction that started at the price of 69420 USD 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 so much compression artifacts just in 3 days lol.
- That's the lasers working.

Have you not seen those Blaster from the galaxy far far away that fire laser half the speed of sound?
- Those are changed plasma bolts

What has science done?!
- Has Science Really Gone Too Far Even as Decided to Use Even Go Want to do Look More Like?
  
  Is this a reference to something or just aneurism posting?

Water is wet
- Easy there, that’s quite a can of worms you’re tipping over.
  
  Indeed, many would argue that water can't be wet, only things that water gets on/in.

I can run at the speed of running, where is my headline?

I think they've changed the headline, but not the embedded video:
- 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.

I can run at the speed of fat

- Show me.

I'm more concerned that it looks like a laser turret from Portal.

But can it shit at the precise speed to fully hit individual turbojets fan blades?

uh ackchuyally it's not the speed of light
- Uhm ackshully it is
  
  ~~it’s not. Light only travels at c in a vacuum.~~
  Looks like I am light years away from joining the ackchyually club.

- This is incorrect by well over a century. The error is likely a conflation of information transmission with mass in context of relativity.
  Thomas Young's 1801 double slit experiment demonstrated the wave particle duality of light. The modern scientific explanations aren't found in relativity, instead quantum mechanics.
  The title is just crap. Don't try to defend it, especially not like this.
