LETTER OF THE MONTH<\/p>\n\n Could it be possible that Tutankhamun\u2019s tomb, KV62, was originally built by Tutankhamun to hold his relatives from el-Amarna, including Queen Nefertiti, and tomb KV55 was commissioned for his own burial (November, p68)? But because he died young, and before the tomb was ready, the priests would have been on a tight schedule to get the young pharaoh entombed. So they utilised KV62 instead, the previous occupants being unceremoniously dumped in KV55, with all the respect befitting heretics who crippled Egypt at the time. Could the rather feminine images of Tutankhamun once attributed to Hatshepsut, be of Nefertiti?<\/p>\n\n\n\n Pat McDonnell<\/strong>, Crosshaven, Ireland<\/p>\n\n\n\n Both KV62 and KV55 are located right in the centre of the Valley of the Kings and are small tombs of similar design. It may be that they were originally intended for senior nobles, but KV62 was extended to include a crypt when it was pressed into service for the burial of Tutankhamun. There has been a lot of speculation that Tutankhamun originally started either KV23 (used by his successor Ay), or KV57 (used by Horemheb), without any firm proof. As far as we know, Tutankhamun salvaged the burials of his relatives from Amarna and placed them directly into KV55. He certainly usurped quite a lot of the funerary goods of Nefertiti, which, as you say, are often distinctly feminine in appearance. I\u2019m not aware of similar speculation with regard to Hatshepsut. She dates to much earlier in the 18th Dynasty and her images would reflect the style of that age.<\/strong><\/p>\n\n\n\n Dylan Bickerstaffe, Egyptologist<\/strong><\/p>\n<\/div><\/section>\n\n The writer of next issue\u2019s Letter Of The Month <\/em>wins a bundle of brilliant sci-fi books <\/strong>from Pan Macmillan. The prize includes the space opera Children Of Memory, <\/em>by award-winning author Adrian Tchaikovsky; the atmospheric Gothic sci-fi Leech, <\/em>by Hiron Ennes; and the contemporary tale of love, space and time Alone With You In The Ether, <\/em>by Olivie Blake, the author of the much-acclaimed The Atlas Six. <\/em> I listened to your podcast entitled Holding <\/em>The <\/em>Universe <\/em>In <\/em>Your <\/em>Hands, <\/em> with Dr Kimberly Arcand. In the discussion on the \u2018sound\u2019 of a black hole, I was able to imagine (most likely incorrectly) the sound being generated by matter rushing towards the black hole, pretty much like a vacuum. This did prompt a question for me: if matter is being sucked into a black hole (to where even Brian Cox doesn\u2019t know), does this contradict the laws of the conservation of the mass and energy, as mass and energy are not being returned to the system? Or, are they being returned to the system, and the black hole (and beyond) is still part of the system?<\/p>\n\n Jim Slattery, Co. Limerick <\/span><\/p>\n\n The pressure waves\/sound waves are moving outwards from the area of the black hole system (versus matter rushing towards the black hole). The sound waves are thought to have been generated by cavities blown out by jets from the supermassive black hole at the centre of the Perseus Cluster of galaxies. Supermassive black holes can pull material swirling around them into their gravitational grasp. During this process, some of this material is redirected away from the black hole in the form of energetic narrow beams, or jets. Such jets can significantly affect how the galaxy and its surroundings evolve.<\/span><\/strong><\/p>\n\n Kimberly Arcand, visualisation scientist<\/strong><\/p>\n\n I read the article on self-driving cars (November, p44) with great interest. I am in agreement with Prof Jack Stilgoe that the rollout of self-driving cars is going to be a slow process, and the UK government\u2019s target of 2025 will be limited to most likely vehicles on motorways. The area this technology needs to be applied to is buses. In the post-COVID years, service levels have become appalling. Staff shortages and illnesses seem to have no end in sight. It will not only end these issues, but it\u2019ll also massively reduce costs for service providers, meaning that bus routes that previously were unviable become possible, meaning (hopefully) better service provision.<\/p>\n\n Luke Russell, Tingley <\/span><\/p>\n\n Email<\/strong> \u2022 reply@sciencefocus.com<\/a><\/p>\n\n Post<\/strong> \u2022 BBC Science Focus<\/em><\/em>, Eagle House, Colston Avenue, Bristol, BS1 4ST<\/p>\n\n Twitter<\/strong> \u2022 @sciencefocus<\/a><\/p>\n\n Facebook<\/strong> \u2022 www.facebook.com\/sciencefocus<\/a><\/p>\n\n Instagram<\/strong> \u2022 @bbcsciencefocus<\/a><\/p>\n\n Editor<\/strong> \u2022<\/strong> Daniel Bennett<\/p>\n\n\n\n Managing editor<\/strong> \u2022<\/strong> Alice Lipscombe-Southwell<\/p>\n\n\n\n Commissioning editor<\/strong> \u2022<\/strong> Jason Goodyer<\/p>\n\n\n\n Digital editor<\/strong> \u2022<\/strong> Thomas Ling<\/p>\n\n\n\n Staff writers<\/strong> \u2022 <\/strong>Alex Hughes, Holly Spanner<\/p>\n\n\n\n Art editor<\/strong> \u2022<\/strong> Joe Eden<\/p>\n\n\n\n Picture editor<\/strong> \u2022<\/strong> James Cutmore<\/p>\n\n\n\n Claire Asher, Scott Balmer, Rob Banino, Steve Benford, Hayley Bennett, Peter Bentley, Steve Boswell, Daniel Bright, Steve Brusatte, Daniel Crespo, Kate Darling, Emma Davies, Sam Falconer, Amy Fleming, Sam Freeman, Alice Gregory, Wendy Hall, Matt Holland, Christian Jarrett, Stephen Kelly, Pete Lawrence, Katie Mack, Nish Manek, Holly McHugh, Michael Mosley, Stephanie Organ, Jheni Osman, Helen Pilcher, Helen Scales, Julia Shaw, Valentin Tkach, Luis Villazon, Joe Waldron, Kimberley Wilson, James Witts.<\/p>\n\n\n\n Business development manager \u2022<\/strong> David D\u2019Souza<\/p>\n\n\n\n Newstrade manager \u2022<\/strong> Rob Brock<\/p>\n\n\n\n Subscriptions director \u2022<\/strong> Jacky Perales-Morris<\/p>\n\n\n\n Direct marketing manager \u2022<\/strong> Kellie Lane <\/p>\n\n\n\n Head of apps and digital edition marketing \u2022<\/strong> Mark Summerton <\/p>\n\n\n\n Laurence Robertson 00353 876 902208 <\/p>\n\n\n\n Director of licensing and syndication \u2022<\/strong> Tim Hudson<\/p>\n\n\n\n International partners manager \u2022<\/strong> Anna Brown <\/p>\n\n\n\n Production director \u2022<\/strong> Sarah Powell<\/p>\n\n\n\n Production coordinator \u2022<\/strong> Lauren Morris<\/p>\n\n\n\n Ad services manager \u2022 <\/strong>Paul Thornton<\/p>\n\n\n\n Ad designer \u2022 <\/strong>Julia Young <\/p>\n\n\n\n Publisher \u2022 <\/strong>Andrew Davies<\/p>\n\n\n\n Group managing director \u2022<\/strong> Andy Marshall<\/p>\n\n\n\n CEO \u2022 <\/strong>Tom Bureau <\/p>\n\n\n\n Chair, editorial review boards \u2022<\/strong> Nicholas Brett<\/p>\n\n\n\n Managing director, consumer products and licensing \u2022 <\/strong>Stephen Davies <\/p>\n\n\n\n Director, magazines and consumer products \u2022 <\/strong>Mandy Thwaites <\/p>\n\n\n\n Compliance manager \u2022 <\/strong>Cameron McEwan <\/p>\n\n\n\n UK publishing coordinator \u2022<\/strong> Eva Abramik <\/p>\n\n\n\n Contact UK.Publishing@bbc.com<\/a> <\/p>\n\n\n\nMusical tombs<\/strong><\/h4>\n\n\n\n
