Three scientists have won the 2020 Nobel prize in physics for their work on black hole formation and the discovery of a supermassive black hole at the centre of our galaxy.
It was 1919. Robert Goddard had released his research paper titled – “A Method of Reaching Extreme Altitudes”. In this paper, he had claimed that a liquid powered rocket had enough potential to take objects along with it to space, and go as far as the moon. The New York Times, on 13th January 1920, …
Perhaps, topics that involve Extraterrestrial Intelligence are one of the most daunting tasks to write about. Having no formal proofs for their existence, and still knowing that anything, including the existence of Extraterrestrial Life, is possible, it is even more complicated to think about what they are based on, what shapes, sizes, and forms, they have – if they do exist. Extraterrestrials have been a major topic for SciFi; many books have been written and as many movies, if not more, have been produced.
Zeno of Elea (c. 495 – c. 430 BC) was a pre-Socratic Greek philosopher of Magna Graecia and a member of the Eleactic School founded by Parmenides. Aristotle called him the inventor of the dialectic He is best known for his Paradoxes, which Bertrand Russell described as “immeasurably subtle and profound”.
We determined Saturn’s gravitational field by reconstruction of Cassini’s trajectory during the Grand Finale, using a coherent microwave link between Earth tracking stations and the spacecraft. Range-rate measurements were obtained from the Doppler shift of a carrier signal sent from the ground at 7.2 GHz (X-band) and retransmitted back to Earth by Cassini’s onboard transponder at 8.4 GHz. An auxiliary downlink at Ka-band (32.5 GHz) was also recorded.
Human Vs Robotic exploration has been – and is still- of a major reason for debate between many scientists. Each presents their own claims and why their ideas are better. It has also been( as usual) a major topic in SciFi movies and has attracted a lot of fans. Before we delve into the pros …
