Awas, Lubang Hitam di Bima Sakti Segera Terbangun

Oleh: Hafiz Pradana Gemilang

London – Di jantung galaksi kita, Bima Sakti, terdapat lubang hitam raksasa yang sedang tertidur. Namun kini lubang hitam itu terusik awan gas yang akan membangunkannya.
Berkat Very Large Telescope ESO, para astronom menemukan awan kiamat itu. Awan gas seukuran Bumi ini akan menghantam lubang hitam tersebut dengan kecepatan 8 juta km/jam dan membangunkannya dengan sangat kasar.
Dari peristiwa ini, para astronom berharap mendapat pendangan mengenai lubang hitam di jantung Bima Sakti ini melalui penelitian pada ledakan radiasi akibat tabrakan tersebut. Peristiwa ini akan menjadi penelitian pertama saat tabrakan pada lubang hitam ini.
Awalnya, penelitian 20 tahun yang dipimpin Reinhard Genzel dari Max-Planck Institute for Extraterretrial Physicsy ini menemukan obyek unik baru bergerak cepat mendekati lubang hitam tersebut dan diketahui akan menghantam lubang hitam tersebut.
“Ini akan menjadi dua tahun yang menarik dan akan memberi informasi sangat berharga pada perilaku materi di sekitar obyek raksasa menakjubkan tersebut,”

Cerita Jembatan Di London

Cerita Jembatan Di London

Engraving of the Old London Bridge showing St. Thomas Chapel during its demolition. There were several old proverbs about old London bridge one said; 'If London Bridge had fewer eyes it would see better,' and 'London Bridge was made for wise men to go over and fools to go under.' Pointing out the dangers of the old passage starlings. The Old London Bridge was by the eighteenth century a dangerous ruin. The houses over-hung the roadway as to cut out the daylight. There were wooden arches across the road to keep the shaky old houses from falling onto each other. The noise of the gushing waters, the clamour of the watermen and the shrieks of drowning wretches was deafening. In 1758, a temporary wooden bridge was built over the Thames while repairs to the old bridge were carried out. This was destroyed by fire (it was supposed by some footman dropping his link among the woodwork). Taylor and Dance the repairers, chopped the old bridge in two and built a new central arch; but the join was so insecure that few persons would venture over it. And by 1823, in sheer desperation a new bridge was built 100 feet westward of the old one. Then in 1824 Mr Rennie began work on removing 182 houses off of the old bridge. There were Roman finds during the dismantling of the bridge; Augustus coins, brass rings, buckles, iron keys, silver-spoons and a guilt dagger.



The Old entrance to medieval London Bridge in St. Magnus The Martyr churchyard St. Magnus The Martyr, by London Bridge was once the main entrance to the old bridge. There has been a church on this site before 1302. The present church was built by Wren after the fire of 1666. It was found necessary to provide better accommodation for pedestrians crossing Old London Bridge, an archway was cut through the tower of St Magnus. Wren had anticipated this, so the work was carried out without difficulty. With the newer bridge moved one hundred yards over, the main Fish Street Hill and church entrance became redundant and half its width became incorporated in the churchyard.

Found opposite in Fish Street Hill during excavation work in 1931. Now on display in St. Magnus The Martyr churchyard
Surprisingly there are still a few pieces of the old London Bridge to be found, alcoves from the old bridge are in the courtyard of Guy's hospital.
Two more can be found in a far corner of Victoria Park in east London.

Also on the wall of the Kings Arms in Newcommen Street since 1880 is the coat of arms which once adorned the southern gateway to the Old London Bridge and dates from 1760 and King George III. On June the 15th 1825, the Lord Mayor laid the foundation stone on the next London Bridge (now rebuilt in Arizona U.S.A.) On August 1st 1831 it was formally opened by King William the IV, accompanied by Queen Adelaide, for the opening of the successor of the old bridge that had been in existence for over 600 years. Who could have thought that the new bridge would last a mere one hundred and thirty years.

From the new London Bridge an artist paints the more Majestic Tower Bridge. At the Tower Bridge Exhibition you can enjoy breathtaking views from the high-level walkways and learn about the history of Tower Bridge and how it was built.
