That which occupies space and possesses rest mass, especially as distinct from energy, is called matter. Matter is present in its various forms through which we can see, observe, and study it. We see matter in our everyday lives, and also when we look up towards the skies, we see it in the form of…

One of the most interesting things that I came across while reading a book was about a horseshoe orbit. How could something like that be possible? What can cause an object…
Universe’s backbone—a black hole?
To escape the Earth’s gravitational influence, you need to have a certain escape velocity (even if you are the Superman), you must fly up towards space with approx. 40,320 km/h, however, a speed of 42.1 km/s is required to escape the Sun’s gravity (and exit the Solar System) from the same position. But what if…
