هذا ما يحدث عندما يبتلع الثقب الأسود نجمًا!
عندما يقترب النجم من الثقب الأسود، فإنه يتفكك إلى سلسلة من الغازات بفعل قوى الجذب الشديدة، وخلال هذه العملية، يتم إطلاق كمية كبيرة من الطاقة كما يظهر في المحاكاة.

يوجد مفهوم أعمق للجاذبية، مفهوم يفسر جوهر الثقوب السوداء وبداية الكون المبكر جدًا، مفهوم عميق يعمل في العالم المايكروسكوبي. سيأتي يوم ويظهر فيه شخصٌ عظيم ويكمل مسيرة إسحاق نيوتن وألبرت أينشتاين ويغير مجرى الفيزياء من جديد.
What happens when there are multiple batteries, Connectedin parallel? AND there is many resistors are connected with unusually lines (series or parallel connection) -Or connect like a star-
Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell. Widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws. These laws can be applied in time and frequency domains and form the basis for network analysis.

Why can't we see the earth spinning?
Here’s a photo had taken over the course of about 90 minutes, looking North. Because the earth is rotating about an axis that passes through the North and South Poles, the stars appear to travel in circles.
The North Star is nearly above the North Pole and so appears almost stationary in this time lapse.
So we don’t see the earth spinning, but because it spins our vantage point changes and the stars, planets, sun, and moon appear to move in circular paths above us.
The linear light paths are planes passing by.

- Has the speed of light been scientifically proven or is it a standard has been set hypothetically?
In his monumental work, Lectures on Physics, Richard Feynman made this comment regarding J. C. Maxwell’s work—which surprised many because Einstein was then considered a very big deal:
• “From a long view of the history of mankind—seen from, say, ten thousand years from now—there can be little doubt that the most significant event of the 19th century will be judged as Maxwell's discovery of the laws of electrodynamics. The American Civil War will pale into provincial insignificance in comparison with this important scientific event of the same decade.”

Now, don’t be scared
These famous T-shirt equations define the physical properties of Electromagnetism.
However, they are clearly meant for people who fill blackboards full of this stuff. They read like a foreign language, but learning about them is not all that difficult once you know what the symbols mean.

There are many ways of writing these equations (this form was published by Oliver Heaviside) and regardless of how they are written they say something absolutely remarkable. For example, the second equation (Gauss’ Law of Magnetism) says there aren’t any magnetic monopoles, even though the equation above it defines the characteristics of electric monopoles. Maxwell's third equation is Faraday's Law. It says that an electric field (E) is simply produced by a varying magnetic field (B).
But remarkably, the fourth equation can be solved for the speed of electromagnetic phenomena in a vacuum, “c” which works out to be 2.99792458 x 10^8 meters per second (present day, agreed-upon number).

Maxwell’s calculation of “c” was actually a simple wave equation that was a function of only two physical constants, the Permittivity (ε) and Permeability (μ) of a vacuum; values that were not hard to measure. So Maxwell’s “c” depends on the accuracy of two constants, which describe only the nature of the vacuum medium…nothing else!
To believe anything can go faster than light is to believe that there is a medium with a Permittivity and Permeability less than vacuum..
So in a very fundamental way, you can’t get a more accurate measurement for “c” for any electromagnetic phenomenon in a vacuum. Remember, Maxwell was only talking about the characteristics of the electromagnetic field in a vacuum. All the relativity stuff came much later with Einstein.
