I can whistle at the speed of sound

It'd be impressive if they fire it at like half the speed of light

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

The army trembling when I bring a mirror

I have wifi router that emits microwaves at the speed of light.

Impressive. The future is awesome! Can we maybe apply this to regular light too? Maybe even green light? Or purple? I'm so excited.

According to the Gell-Mann amnesia effect, the same people also write about politics, environment and society.

I would hope so

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.

Wake me up when I can buy a lightsaber.

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

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

Have you not seen those Blaster from the galaxy far far away that fire laser half the speed of sound?

What has science done?!

Water is wet

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 can run at the speed of fat

I can run at faster than the speed of sound at mach 2

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

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

uh ackchuyally it's not the speed of light

I think the significance here is that mass = energy and it's implied that these lasers carry enough energy to do damage, so it's essentially mass moving at the speed of light, which shouldn't be possible if Einstein was right.
