Kehidupan Alien Disedot Lubang Hitam Antariksa?

Beberapa astronom percaya kurangnya bukti keberadaan alien yang dikenal sebagai teori ‘Great Silence’ disebabkan kekuatan ledakan destruktif dari sebuah bintang. Seperti apa?

Ilmuwan masih bingung untuk melakukan konfirmasi secara pasti soal kehidupan di luar planet Bumi. Kini, beberapa di antaranya percaya kekuatan penghancur dari ledakan bintang, atau sering dikenal dengan nama white dwarf hypernova, telah memusnahkan keberadaan alien. Makhluk asing itu sudah tersedot ke lubang hitam.

Dalam proses itu, saat bintang kerdil yang muncul dari runtuhan sisa bintang tua tersebut tidak stabil dan meledak, mungkin turut pula menghancurkan kehidupan asing di sekelilingnya.

Ilmuwan juga percaya kemungkinan Bumi dapat hancur akibat proses ledakan sinar gamma. Radiasi gamma yang rutin menghasilkan oksida nitrat yang mungkin merusak ozon.

Meskipun begitu, Dr. Edward Sion dari Villanova University di Pennsylvania, mengatakan kepada Daily Galaxy, peristiwa menakutkan itu kecil kemungkinan terjadi dalam waktu dekat.

Hipernova pada dasarnya merupakan supernova (ledakan bintang) yang raksasa. Proses ledakan itu menghasilkan fenomena yang dikenal dengan nama stellar-mass black hole. Lubang hitam itu terbentuk dari keruntuhan gravitasi.

Acute appendicitis is defined as the acute inflammation of the appendix. It is considered to be the most common cause of abdominal pain and distress in children and teenagers worldwide (ages 4-15). The appendix is a channel in its interior that communicates with the large intestine where feces semifluidas. The appendix is a small pouch attached to your large intestine. It is thought that appendicitis begins when the opening from the appendix into the cecum becomes blocked. The blockage may be due to a build-up of thick mucus within the appendix or to stool that enters the appendix from the cecum. When the appendix is blocked by calculus and feces or it is squeezed by the lymph nodes (due to bacterial infection, the lymph nodes usually become swollen and press against the appendix), it swells and usually doesn't receive enough blood. Bacteria grow inside the appendix, eventually causing its death. In acute appendicitis, the inflammation of the appendix is seriou...

Nursing Diagnosis for Rheumatoid Arthritis (RA)

Nursing Diagnosis for Rheumatoid Arthritis (RA) Rheumatoid Arthritis (RA) is a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks synovial joints. The process produces an inflammatory response of the synovium (synovitis) secondary to hyperplasia of synovial cells, excess synovial fluid, and the development of pannus in the synovium. The pathology of the disease process often leads to the destruction of articular cartilage and ankylosis of the joints. Rheumatoid arthritis can also produce diffuse inflammation in the lungs, pericardium, pleura, and sclera, and also nodular lesions, most common in subcutaneous tissue. Although the cause of rheumatoid arthritis is unknown, autoimmunity plays a pivotal role in both its chronicity and progression, and RA is considered a systemic autoimmune disease.
