Idea find black holes using grav. lensing

AI Thread Summary
The discussion explores the concept of using gravitational lensing to identify distant black holes by observing the light from stars behind them. It suggests that a large black hole could create a superimposed image of multiple stars, potentially misleading observers into thinking they are seeing a single massive star. The idea is that the lensing effects could allow astronomers to deduce the size of the black hole based on the light patterns observed. Participants note that gravitational lensing is already a recognized method for discovering massive objects, and they express interest in the mathematical aspects of this phenomenon. The conversation emphasizes the importance of combining imagination with scientific knowledge in exploring such theories.

Ok I have this idea and i need you all to bash it so i can see what's wrong with it. Ok imagine a very very large black hole at distances like 10 billion light years, imagine that there could be black holes larger than we can fathom and imagine how many stars would lie behind such an anomaly, so all of these stars's light would be lensed around the black hole, now when that light comes to our eyes we would picture the light to ie.. left or right of the black hole eventhough it lies distinctly behind the black hole, and whether the starts lie more to the middle or not would change the light imaginary image to us ie.. the more directly behind the star the more to the opposite side of the star would the imaginary image be, so if you can see this picture that I am painting imaghine millions and millions of these star being lensed and all this light being superimposed upon one big area, the more stars the larger area they would be superimposed upon, so what you get IN OUR EYES is a HUGE star in the sky, a very bright light, with telescopes we see it and say wow that's huge like size of beeteljuice maybe, but i think that may not be a star at all, just the superimpositon of millions of stars that have all been lensed by a stellar black hole, so what I am saying is the mega stars in the sky very far away could actually be a guiding map to black holes, and mathematically I've played with the equations a lil you can actually dicern the size of the black hole via, light and lensing effects.

bash away, cause i know it's coming, just a silly idea i know but it's had my mind going into a frenzy lately, but i'll humbly accept any critism you have

another things, anyone very well gifted in the study of time know of good threads or want to share some interesting ideas of time?

no idea? sorry to bug all of you.
 
No bug, imagination is a wonderful thing so long as it is educated with some knowledge. In this case the problem will be to obtain a lensed image that is a crisp star-like point of light, normally they are smeared out arcs or whatever.

People are already looking for and have found massive objects using gravitational lensing. You can see some pretty neat pictures of gravitational lensing effects on line (Google for Einstein Cross, for example).

For an example of people finding black holes using gravitational lensing.
 
wow

thanx nate I've never looked or read about that just seemed logical that lensing effects of large stars could also be used with black holes, anymore information anyone has on the subject would be useful such as the math behind it, such as how much lensing maybe can show us the size of the black hole and so on, like i have a question, i would imagine not all black holes would lense the same is it the size that makes it worse or what, does a lil black hole do the same as a stellar black hole since they are both supposed infinite gravity singularities.
 
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.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
