Universe Is the Black Hole

Physico-mathematical parallels between the Expansive Nondecelerative Universe model and black holes justify us to be convicted that each universe can be considered as a black hole. This is why there must exist a fractal arrangement of the Multiuniverse that is boundless both in time and space.

Closest Star Seen Orbiting the Supermassive Black Hole at the Centre of the Milky Way a

Measurements of stellar velocities 1−6 and variable X-ray emission 7 near the centre of the Milky Way have provided the strongest evidence so far that the dark mass concentrations seen in many galac-tic nuclei 8 are likely supermassive black holes, but have not yet excluded several alternative configurations. Here we report ten years of high resolution astrometric imaging that allow us to trace...

With shorter periods of hospitalazation, fewer patient beds and more health care facilities in the society, patients are now more acutely ill and highly dependent, causing less opportunities for medical students to practice and learn basic clinical skills. On the other hand, enhanced patient rights and other learnig limitations require that professional education provide not only knowledge and ...

Solar cycle 24: what is the Sun up to

of an M7.9 class flare on 13 March 2012. It is shown here in the 131 Å wavelength, which is particularly good for seeing solar flares and is typically colourized in teal. The flare was from the same active region, no. 1429, that produced flares and coronal mass ejections the entire week. The region had been moving across the face of the Sun since 2 March, then rotated out of Earth view. But per...
