The new BLACK HOLE image explained by an ASTROPHYSICIST | Your questions answered
The new BLACK HOLE image explained by an ASTROPHYSICIST | Your questions answered Kwabena Ofori Osei 39 Views • 4 years ago

The Event Horizon Telescope collaboration just released the first ever image of the Milky Way’s supermassive black hole (the same group that took the first ever image of a black hole in 2019 - the one in the centre of the Messier 87 galaxy). What do we learn from this image? Why is it orange? Why is it different to the M87 image? Why is it blurry? And can we observe the same thing with the James Webb Space Telescope?

Why yes this was filmed and edited in a single day. Thanks for noticing. Yes I am exhausted.

👩🏽‍💻 I'm Dr Becky Smethurst, an astrophysicist at University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on *how* we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

African Revolution Has Been Lost.
African Revolution Has Been Lost. Baka Omubo 39 Views • 4 years ago

For many centuries now Africans have been subjected to exploitation, colonisation, enslavement by the capitalist maritime nations of western Europe and other marauders, like Christians, Jews AND Muslims. If You are black person and you follow Christianity, Hebrew Israelism, or Islam you have joined the invaders who destroyed Africa's ancient civilisations. They seized and laid waste her natural wealth. By the end of the 19th Century almost the whole of Africa had been conquered - by trickery or the force of superior arms - and brought beneath the alien yoke of a handful of European powers - Britain, France, Portugal, Belgium, Germany and Spain. At the end of the second world war, only Ethiopia and Liberia could claim to be African states governed by Africans. By 2000 the whole picture had been transformed. Bitter bloody wars had been fought in Angola, Mozambique, Kenya, and Zimbabwe, the Republic of South Africa, and South-West Africa- Namibia. However White minorities continued to dominate Africa on behalf of the colonial master. Proof that our leaders are puppets is when African Presidents, & First Ladies, President aboard a common bus heading to Buckingham Palace to attend state reception in honour of Queen Elizabeth II despite her family looting their lands…This is the time we clearly must understand how a Plan to dominate Africans have been, in place all along and continues to this day. It is called The Imperial Charter. It was drawn up in Washington during the “slave trade”, then quietly negotiated at the “Berlin conference in 1884” while the Western powers shared Africa; renegotiated secretly in Yalta at the time of division of the world in two blocks after the Second World War and during the creation of the “League of Nations”, the ancestor of the “UN”. The Charter Has 28 Articles. The African nationalist Movement, Patriotic Spirit, Sovereignty, in defence of National Borders in the African continent,digital revolution,African politics, Democratic Elections…etc.. Including political parties like ZanuPf, KANU, Frelimo, MPLA, ANC- SWAPO.. Were all infiltrated and sold us out! For example Kenyatta was not a genuine revolutionary this sad to say have FAILED MDH .Join the movement fighting The god Set at all levels Mentally, physically, spiritually and Materially. In this case DO NOT SELL your SOUL to any Revolution that denies your Venerated ancestors and Divinities. To Explore Many Informative Spiritual Life Science Topics, Enrol into Our
