AI Thread Summary
Different types of waves exist in both matter and space, with gravitational waves and light waves being notable examples that travel at the same speed. Light is classified as an electromagnetic wave, which is a broader category that includes various types of waves such as radio waves, microwaves, and X-rays. The discussion highlights that all electromagnetic waves travel at the speed of light. The correlation between waves in matter, like P waves and S waves, and waves in space is not clearly established. Understanding these concepts is essential for grasping the nature of wave propagation in different mediums.

I know there are different types of waves in matter, for example P waves, S waves, etc. But do these correlate to waves in space? For example I know of two types of waves through space: gravitational waves and light waves, which both travel at precisely the same speed. Are there any more types of waves through space?

I don't know if they correlate to waves in space because I don't really understand big words such as correlate (Only 13) but for the second question there are electromagnetic waves. Unless that is what you meant by light waves. If not then you should know that light is an electromagnetic wave, and all electromagnetic waves travel the same speed (the speed of light).

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
