How To See Through an Invisibility Cloak
AMESN writes "Ways to bend light around objects and render them invisible are becoming a major field of scientific study and gaining ground. While no actual invisibility cloak exists yet, researchers are also theorizing on how to beat the perfect cloak."
The kind I want to go out with. WooHoo; particle launcher!
Great minds think alike; fools seldom differ.
turn it on?
No invisibility cloak can hide the fact that it's still a solid object. That or utilize various frequencies of EM as it would be extremely difficult to defeat radar + infared + visible + UV all at the same time.

Just throw a stone at it.
In that scenario aren't you supplying the particle launcher yourself?
I see even classic Slashdot is now pretty much unusable on dial up anymore.
If you can, it's not perfect.
The real problem isn't detecting it. It's knowing that you need to be trying to detect it in the first place, and approximately when and in what area.

TFA mentions using charged particles and multiple wavelengths of EM to detect a clocked object. TFA suggests that they were measuring the actual effect on the path of the radiation its self although it should be pointed out that this is quite possibly unnecessary as high energy charged particle entering a solid material undergo an extremely high de-acceleration phase which causes charged particles to emit EM radiation. It's called Bremsstrahlung radiation and could quite possibly be detected.

A perfect invisibility cloak is also a perfect blindness cloak. Unless you make i.e. missiles or bullets (dodge that, Neo!) with it, things with a predefined target, could be somewhat useless for most interesting uses. The imperfect are the useful ones.
I am not sure why people are being so slow to accept this.
Because nothing in world has to be 100% perfect. It just has to work good enough. And maybe later there will be new discoveries that will improve it. That's how technology and science has always worked.
Sure, there will always be ways to get around the invisibility cloak, just like people have ways to get around DRM. But it doesn't make it completely useless or non-working technology.
An "invisibility cloak" these days doesn't just necessarily apply to the visible light spectrum. The cloak could be a thermal or radar "invisibility" cloak, leaving an object perfectly visible to the naked eye, but invisible on other scans. Penetrating thermal invisibility cloaks might end up more important, because camouflage can take care of visible light from overhead, it's the thermal that's the giveaway.
Admit it. You post strawman arguments as AC so you get modded Insightful for refuting them, rather than Troll
Thanks, buddy. I suddenly feel much better about myself.
You can drink a blessed potion of see invisible or eat an invisible stalker's corpse while invisible.

Better yet, a well-placed bullet. Just spray bullets in all directions at all times.

Everyone knows firing short, repeated bursts of tachyons between a 3 dimensional grid made up of Federation star ships is the most effective way to detect invisible, cloaked objects.
Fact: Everything I say is fiction.
Use a scrying spell, obviously.
