Unveiling the Mysteries of Dark Objects

  • Thread starter Tyger
  • Start date
In summary, there are various types of dark objects that have been observed, including solar flare loops, quasars, B. C. Lacertae objects, ball lightning, and smoke rings. These objects emit electromagnetic radiation over the entire spectrum, but also have a dark phase in which they absorb light. The mechanisms behind this absorption are currently unknown and may involve new physics. Some speculate that the "dark ring object" mentioned in a forum thread may have been a smoke ring, but others argue that there are other, unexplained dark objects such as sunspots and round blobs on the sun.

"Dark Objects"

Some objects emit electromagnetic radiation over the entire spectrum, from radio waves to X-rays. Solar flare loops, quasars and, the most amazing are, B. C. Larcertae Objects which display an extremely flat spectrum. This is not just broad band syncrotron radiation. Ball lightning and similar ring like objects have also been reported to emit a pure white light (but not in every case, it might be added).

If this weren't strange enough the same types of objects seem to have a "dark" phase. Dark ball lightning and dark solar flare loops have been observed. Here is a thread related to a "dark ring" object.

Dark quasars or B. C. Lacertae objects would be very hard to observe so we can't say that they occur.

What mechanism would allow such an object to absorb light over nearly the entire spectrum? Bet there's some ineresting new physics here!

Hmmm...Black paint on a F-117A stealth fighter?
:wink:

hmmm, well any thing that is a perfect black body must absorb and emit em radiation of all wavelengths.

That "dark ring object" was a smoke-ring, if I've read the article correctly. Hardly mysterious in its properties.

I did't see any speculation in the articles as to the nature of the ring. Why don't we see large smoke rings like this more often? And there are also "bright" rings, sometimes associated with lightning.

And I left out an important class of dark objects, Sunspots, which are considerably darker than their surroundings. I've just read a report yesterday that another type of dark object has been found on the Sun, a sort of round blob that travels outward during flares.
 

What are dark objects?

Dark objects are astronomical bodies or structures that emit little or no electromagnetic radiation. They are difficult to detect and study because they do not emit light.

What are the types of dark objects?

The most commonly studied types of dark objects are dark matter and black holes. Dark matter is a type of matter that does not interact with light and is believed to make up a large portion of the universe's mass. Black holes are extremely dense objects with a gravitational pull so strong that not even light can escape from them.

How do scientists study dark objects?

Scientists use a variety of techniques and instruments to study dark objects. These include gravitational lensing, which is the bending of light by the gravity of a dark object, and indirect detection methods such as observing the effects of dark objects on visible matter.

What is the importance of studying dark objects?

Studying dark objects is crucial for understanding the structure and evolution of the universe. Dark matter plays a significant role in the formation of galaxies and the large-scale structure of the universe, while black holes have a major impact on their surrounding environments.

What are some current mysteries surrounding dark objects?

There are many unanswered questions about dark objects, such as the exact nature of dark matter and the behavior of matter as it falls into a black hole. Scientists are also trying to understand how dark objects interact with and influence visible matter, and if there are other types of dark objects that have yet to be discovered.
