Physics is the study of matter, energy, and the interactions between them. It encompasses a wide range of topics, including mechanics, thermodynamics, electromagnetism, and optics.
Studying physics allows us to better understand the natural world and the laws that govern it. It also helps us develop new technologies and solve real-world problems.
According to Einstein's theory of relativity, space and time are intricately linked and form a four-dimensional continuum known as spacetime. Space and time are no longer considered separate entities, but rather a unified fabric.
A black hole is a region of spacetime with such a strong gravitational pull that nothing, not even light, can escape from it. It is formed when a massive star collapses under its own weight, causing its core to become infinitely dense.
Black holes can significantly distort the fabric of spacetime, causing nearby objects to orbit around them and even slowing down time. They can also emit powerful jets of radiation and impact the evolution of galaxies.
