"I can show it on paper. I can only prove it by building one, twelve astronomical units from the Sun, unmanned, with the inspectorate watching."Vinak Pillai, answer to President Tuji, 2286, kept in the Magellan Consortium's archive
Vinak Pillai was a physicist of the Magellan Consortium who invented the Pillai hyperdrive, the faster-than-light drive of human space. Her paper of 2281 showed why the Imaeda drive's ship Infinite had vanished in the previous century and how a drive could translate a ship between stars without repeating it. The Consortium's test vehicle Anant Two made the first jump on 14 August 2289. The drive opened the Expansion Era, and every human starship since has carried a descendant of it.
Early life
Pillai was born in Thiruvananthapuram on 2 June 2243. Her father was a Bharat Resources fusion engineer who had spent the Solar War at the Swarga's anchor station and the peace at the Unification Works Program's Melas tether. She grew up on the tether's Martian end, in Bartolomeu, in the Program's years. She read physics at the Indian Institute of Science and took a doctorate at the Federation's Magellan observatory on Europa in 2268, on the gravitational lensing of the Jovian system.
She stayed at Magellan when the Program merged the observatory, Bharat's propulsion laboratory and Xi's materials institute into the Magellan Consortium in 2270. Her son Mahesh was born on Europa in 2266. She raised him at Magellan, where he learned to wind coils in the Consortium's propulsion halls before he was twenty.
The theory
Pillai's work through the 2270s was on the geometry of spacetime around masses, a field the Darmstadt Convention permitted because it was astronomy. In 2281 she published a paper, which the Consortium's reviewers held for a year, showing that the Imaeda drive's failure lay in the assumption that a ship could be translated from inside a gravity well. The Infinite had activated its fold 4 million kilometres from Europa, inside the region where the Sun's gradient made the endpoint undefined. A drive operating where the gradient fell below a threshold, which for a star of the Sun's mass lay about twelve astronomical units out, could translate a mass up to ten light years and arrive.
The next step was not astronomy, and Pillai spent 2282 to 2286 writing letters. The Consortium's director refused to let her build a coil. The inspectorate said that a drive not on the Imaeda Institute's principles was not covered by the Convention, and that it would prosecute anyone who built one. President Tuji's Scientific Research minister, Dr Ayo Bankole, read the paper in 2285 and took it to Tuji in March 2286. Tuji asked whether Pillai could show that her drive would not do what Imaeda's had done. She answered that she could show it on paper and could only prove it by building one, unmanned, twelve astronomical units from the Sun, with the inspectorate watching.
Tuji ordered the Imaeda Institute's papers unsealed to the Consortium in June 2286. Pillai spent eight months with them and reported in February 2287 that the Institute had known its endpoint was undefined, had calculated a probability of arrival of 60 percent, and had gone. The Infinite had not exploded. It had arrived somewhere.
The drive
The Senate amended the Convention on 21 March 2288 by 61 votes to 44. The inspectorate set the threshold for the Sun at fifteen astronomical units, three beyond Pillai's figure, and the Pillai radius has stood at fifteen ever since. The Consortium built the drive at Magellan through 2288 on a budget of 40 billion credits. The Anant Two translated at 0900 on 14 August 2289, 15.3 astronomical units from the Sun, and its carrier wave reached Magellan from 36 light days out on 19 September. The Anant Three made the return jump in December 2289, and a crewed vehicle jumped a light year out and back in 2290.
Pillai stood beside Elliot O'Neil at his inauguration as President on 15 January 2292. He had been elected on the drive.
Later life
Pillai led the Consortium's propulsion work through the 2290s. The first generation's coils failed under charge, and the losses of two test vehicles and the survey ship Kepler, with nineteen aboard, in 2296 weighed on her for the rest of her life. The second generation's segmented coils, which could fail one at a time, were her answer, and they flew in the Voyager class from 2299. Her son wound the Anant Two's coils and commanded the survey ship Grissom from 2300.
Pillai retired from the Consortium in 2305 and lived at Magellan for the rest of her life. She read every one of the Grissom's survey reports as the couriers brought them. She lived to read the report of the Voor contact at Cirban in 2317, and to hear that the Voor ship had made in forty minutes the jump that her son's ship had made in six hours. She died at Magellan on 11 March 2324, aged eighty.
Legacy
The Pillai hyperdrive made the Expansion Era. Its rules, that a ship must jump from beyond a system's gravity well and that every jump is seen, set the terms of human navigation and war for two centuries. The Magellan Consortium built five generations of the drive. It tested the fifth on 14 August 2499, two hundred and ten years to the day after the Anant Two. The Pillai radius bears her name in every human language, and the Consortium's propulsion hall at Magellan has borne it since 2325.
