Researchers use lasers to generate terahertz pulses via interaction with a target. In this case, the target was an extremely thin water film -- approximately 200 microns or about the thickness of two pieces of paper -- created using water suspended between two aluminum wires.

It’s a good thing he didn’t believe anyone telling him ‘the science is settled.’

” “Water is one of the richest resources on Earth, so it was really important for us to be able to generate these waves from water. “

I am not understanding this.

Very Interesting....

What about Holy Water?

I wonder if this is how I feel density differences several feet from my hands...

I’ve used this ability in the past when screwing drywall to the studs. I just move my open hand and I feel the stud location behind the drywall.

It also works on brain tumor locations....

I read about this technology several years ago in Japanese research. They were using it to determine contents of rooms in the pyramids. Kind of like an energy ultrasound.

Per Wiki:

Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency[1] (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the ITU-designated band of frequencies from 0.3 to 3 terahertz (THz; 1 THz = 1012 Hz). Wavelengths of radiation in the terahertz band correspondingly range from 1 mm to 0.1 mm (or 100 μm). Because terahertz radiation begins at a wavelength of one millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as submillimeter waves, especially in astronomy.

Photon energy in the THz regime is less than the band-gap energy of non-metallic materials and thus THz radiation can penetrate such materials. THz beams transmitted through materials can be used for material characterization, layer inspection, and as an alternative to X-rays for producing high resolution images of the interior of solid objects.[2]

Terahertz radiation occupies a middle ground between microwaves and infrared light waves known as the “terahertz gap”, where technology for its generation and manipulation is in its infancy. It represents the region in the electromagnetic spectrum where the frequency of electromagnetic radiation becomes too high to be measured digitally via electronic counters, so must be measured by proxy using the properties of wavelength and energy. Similarly, the generation and modulation of coherent electromagnetic signals in this frequency range ceases to be possible by the conventional electronic devices used to generate radio waves and microwaves, requiring the development of new devices and techniques.
