Cathode rays are now known to be a beam of electrons.
When early experimenters were investigating the electrical properties of gases, the found glows filling the tube as the gas pressure was reduced. Eventually, at very low pressure, the glow disappeared and it became evident that something leaving the cathode caused a glow in the glass behind the anode, whose shadow could be seen in that glow, so clearly something was leaving the cathode and striking the glass.

Cathode is a name used also today.
What is the modern day name for cathode ray tube?
The Cathode Ray Tube is called CRT, but I don't know of any "modern day" name. I know it was discovered by J.J. Thomson, who discovered electrons through the Cathode Ray Tube.

What did Thomson used a cathode ray to discover the what?
J.J. Thomson used a cathode ray to discover the electron in 1897. Through his experiments, he demonstrated that cathode rays were composed of negatively charged particles, which were much smaller than atoms. This groundbreaking discovery led to the understanding of atomic structure and the development of the field of particle physics. Thomson's work fundamentally changed the perception of matter and laid the groundwork for modern atomic theory.
What is the relationship between the Higgs field and the concept of ether in modern physics?
In modern physics, the Higgs field is a fundamental field that gives particles their mass. The concept of ether, which was once believed to be a medium that filled space, has been largely abandoned in favor of the Higgs field as the explanation for mass in the universe. The Higgs field is a more accepted and scientifically supported concept in contemporary physics.
What type of physics is the theory of relativity?
Modern physics!
