When photons from distant stars [etc] are received why does the rest of the electromagnetic spectrum not reach us.

In summary, photons are the carriers of all electromagnetic radiation, but different sources emit specific frequencies and not the entire spectrum. This means that not all frequencies reach us, and interstellar and intergalactic materials can block certain types of radiation. This is why we use specialized instruments, like radio and x-ray telescopes, to capture different wavelengths from distant stars.

In comparison to radio waves (in general) it's usually the opposite because interstellar and intergalactic materials (powders, etc) are transparent to radio waves but not always to visible light.Martyn Arthur said:

Am I missing something, but aren't photons the carrier of all electromagnetic radiation regardless of frequency? So they're all being emitted, some are absorbed or transduced along the way, but a lot reaches us. We view the cosmos in many frequencies right here on Earth.

No they are not.
EM emissions is mostly frequency specific ... eg. monochromatic light ... a red laser ... is very frequency specific radio, TV broadcasts ...
else why would they bother to give you a specific frequency to tune to for your favourite FM radio station eg. 101.7 MHz
Some sources are broad band, but even then not necessarily/not likely to be right across the whole spectrum
ohhh and photons are quantum packets of energy (at a specific frequency)
FAQ: Exploring the Mystery of Unreachable EMR
What is "Unreachable EMR"?
"Unreachable EMR" refers to electromagnetic radiation (EMR) that cannot be detected or accessed through traditional means. This type of EMR is often referred to as "dark matter" or "dark energy" in the scientific community.
Why is it important to study "Unreachable EMR"?
Studying "Unreachable EMR" can provide insight into the structure and behavior of the universe. It can also help us better understand the origins and evolution of our universe.
How do scientists study "Unreachable EMR"?
Scientists use a variety of methods, such as analyzing gravitational lensing, studying the cosmic microwave background, and observing the effects of dark matter on visible matter, to study "Unreachable EMR". These methods allow scientists to indirectly detect and study this mysterious form of EMR.
What are some potential implications of understanding "Unreachable EMR"?
Understanding "Unreachable EMR" could lead to advancements in our understanding of the fundamental laws of physics and the structure of the universe. It could also have practical applications, such as improving our understanding of dark matter and energy, and potentially leading to new technologies.
Are there any current theories or hypotheses about "Unreachable EMR"?
Yes, there are various theories and hypotheses about the nature of "Unreachable EMR". Some scientists believe it could be made up of exotic particles that interact very weakly with other forms of matter, while others suggest it may be a manifestation of the curvature of space-time. However, more research and data are needed to fully understand this mysterious form of EMR.
