Because it absorbs visible light.
Faraday's dark space is created in a gas discharge tube when electrons gain enough energy to collide with gas atoms, causing them to emit light. The dark space is a region near the cathode where electrons lose energy due to collision with gas atoms, causing a decrease in electron density and subsequent decrease in light emission.
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
Dark Matter
Cathode rays are negatively charged particles that move in curved paths in the presence of a magnetic field. The direction and curvature of the cathode rays can be controlled by adjusting the strength and orientation of the magnetic field. This phenomenon is known as the magnetic deflection of cathode rays and is used in devices like cathode ray tubes.
A modern day name for cathode rays is an electrons.
An Aston dark space is a dark space in a glow discharge which is adjacent to the cathode.
The cathode space charge is determined by the voltage on the filament.

The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
Negative space is dark energy and dark matter.
Dark Space I was created on 2003-10-13.
Dark Space III was created on 2008-05-30.
Yes! space is pitch black! however, because of the light of the stars,and especially the sun..... space is really glowing with light . but it is still dark in space .
Dark Space - 2013 is rated/received certificates of: Germany:12
Yeah, the Space Aliens grow in the dark, but you charge them in the light :)
All over the dark expanse of space.
has common cathode
