NASA pode ter descoberto a dobra espacial de Star Trek
A agência espacial já teria produzido algo parecido com a “dobra espacial” Star Trek dentro de um motor experimental.
O conceito de motor de dobra pode parecer algo firmemente enraizada na série de TV de ficção científica Star Trek, mas na década de 1990 o físico Miguel Alcubierre efetivamente teria invocado a ideia de uma “bolha de dobra”, que poderia ser formada em torno de uma nave espacial, usando uma onda especial para contrair o espaço em frente da nave e expandir o espaço atrás dela.
Ao andar dentro desta bolha, a nave espacial seria capaz de viajar longas distâncias sem passar pelo espaço entre elas. Avançando para os dias atuais, a NASA pode ter encontrado a primeira evidência de um campo de dobra da vida real que está sendo produzida por um novo tipo de motor conhecido como o EmDrive.
Desenvolvido pelo cientista americano Guido Fetta, este novo sistema de propulsão pode produzir um impulso sem a necessidade de qualquer tipo de propulsor. Agora, no entanto, há relatos que sugerem que quando os raios lasers são disparados através de câmara de ressonância do EmDrive, estes podem realmente viajar mais rápido que a velocidade da luz, uma descoberta que poderia indicar que a unidade está produzindo algo como um campo de dobra ou bolha.
Os resultados ainda têm que ser confirmados, mas isso poderia significar que não só é possível, como a dobra espacial já pode ter sido inventada ela Nasa, ainda que por acidente.

mythosFinnish mythology series: Ajatar
In Finnish folklore, Ajatar (also known as Ajattara or Ajattaro) is an evil female spirit of the forest, “the devil of the woods”. She has many forms and depending on the description, she’s said to be a witch, a ghost, a snake or a dragon. Ajatar spreads diseases and plague and anyone who looks at her becomes sick. It was believed that Ajatar was the reason why people got lost in the woods and her name is probably derived from the Finnish word ajattaa; ‘to lead’, ‘to pursue’.

April 29th 1770: Cook lands at Botany Bay
On this day in 1770, Captain James Cook and his ship the Endeavour landed at Botany Bay, Australia. Cook’s ‘discovery’ of Australia and his claiming the land for Britain set the stage for further exploration of the nation and settlement by the British, initially using the island as a penal colony. This colonisation was accompanied with a campaign of violence and persecution against the indigenous Australians, and has left a legacy that is still felt today in modern Australia. Botany Bay is in Sydney, New South Wales and was initially called ‘Sting Ray Harbour’ by Cook due to the stingrays they caught there, but he later named it Botany Bay due to the vast quantity of plants there; it was later the site of the arrival of the First Fleet from Europe in 1788. After his seminal voyage to Australia, Cook continued his travels and undertook three voyages in total. On the third voyage, Cook landed in Hawaii where the indigenous islanders allegedly initially worshipped him as a god, as his arrival fit the story of the return of their deity Lono. However, relations soon soured, and Cook was eventually killed by native Hawaiians in 1779.
hello b., I have a question; how do you align your image sequences?
hi!
i’m kind of embarrassed to say - i import the files into photoshop as layers, then line them up by hand and by eye. i hesitate to go into the method further, because i’m sure there are better, automated ways of doing it. pappubahry was always good at that sort of thing - he doesn’t seem to be active on tumblr at the moment, but you might be able to catch him on twitter.
if you are going to align images in photoshop, my method to align images A, B, C, D, etc., is to invert image A, then set the opacity of B to 50%. this makes any matching areas a neutral grey, and any non-matching areas (e.g. under- or overlapping edges) appear as black or white. then nudge or transform B until the black and white areas are minimized and the images are aligned. set B back to 100% opacity and repeat for C, D, etc. don’t forget to invert A back to it’s original form when you’re done.
again, i wouldn’t recommend the method - there are sure to be bits of software that do the same thing at the click of a button - but it’s what i do, and it might be useful sometime!
thanks, as always, for getting in touch.
regards,
b.

ageThe Only Christian Asian Nation (and some other interesting things about the Philippines)
Its been a while since I did a facts list…here we go:
- The Philippines has the highest rate of discovery of new animal species with 16 new species of mammals discovered just in the last 10 years.
- The world’s largest pearl was discovered by a Filipino diver in the Palawan Sea in 1934. Known as the “Pearl of Lao Tzu,” or “Pearl of Allah,” it is worth around US$40 million, and is believed to be 600 years old.
- The Philippines is the only country in the world whose flag is hoisted upside down when the country is at war.
- The yo-yo had its beginnings as an ancient Filipino studded hunting weapon attached to a 20-foot rope.
- There are between 120 and 175 individual languages spoken in the Philippines, 171 of which are living while the other four no longer have any known speakers.
- Both University of Santo Tomas in Manila, founded in 1611, and the University of San Carlos in Cebu City, founded in 1595, are older than Harvard University (which was only founded in 1636)
Numerologia: O significado do número Sete
7- Produto da união do ternário (espiritual) com o quartenário (material).
O número sete é considerado o número da ordem perfeita, representando um ciclo ou período existencial completo.
A escala musical tem sete notas, sete são as cores do arco-íris, sete os chacras principais, sete as esferas planetárias tradicionais, e ainda sete são os pecados capitais e os dias da criação, os dias da semana.
Pode-se dizer que toda a mística e toda a tradição cosmogônica ocidental (e também, em parte, a oriental) estão baseadas no sistema setenário.
