The conundrum posed by Einstein's Theory of Relativity that allows space-time to loop back on itself, theoretically allowing time-travel to the past, has been resolved, according to two physicists writing in the journal New Scientist.
Quantum Theory, which describes small particles as both waves and matter, yields probabilities on the location of these particles, the particles appearing -- in layman's terms -- where the waves interfere with each other constructively.
Daniel Greenberger, from the City University of New York, and Karl Svozil, of the Vienna University of Technology in Austria, solved the relativistic equations for waves travelling backwards in time and found they always interfered destructively.
This means the particles do not appear and the conundrum does not arise.
"If you travel into the past quantum mechanically, you would only see those alternatives consistent with the world you left behind you," Greenberger said, implying that the person concerned would be unable to change the past -- the essential requirement for time-travel to make any sense.
Quantum Theory explains the behavior of sub-atomic particles, which are seen as multiple waves, each following its own path through space-time.
There is nothing in the theory against time travel, as waves travel backwards as well as forwards. Greenberger and Svozil's solutions suggest that when they travelled backwards, destructive interference occurred that prevented anything different happening to what actually occurred.
VAGUE: The criteria of the amnesty remain unclear, but it would cover political violence from 1999 to today, and those convicted of murder or drug trafficking would not qualify Venezuelan Acting President Delcy Rodriguez on Friday announced an amnesty bill that could lead to the release of hundreds of prisoners, including opposition leaders, journalists and human rights activists detained for political reasons. The measure had long been sought by the US-backed opposition. It is the latest concession Rodriguez has made since taking the reins of the country on Jan. 3 after the brazen seizure of then-Venezuelan president Nicolas Maduro. Rodriguez told a gathering of justices, magistrates, ministers, military brass and other government leaders that the ruling party-controlled Venezuelan National Assembly would take up the bill with urgency. Rodriguez also announced the shutdown
Civil society leaders and members of a left-wing coalition yesterday filed impeachment complaints against Philippine Vice President Sara Duterte, restarting a process sidelined by the Supreme Court last year. Both cases accuse Duterte of misusing public funds during her term as education secretary, while one revives allegations that she threatened to assassinate former ally Philippine President Ferdinand Marcos Jr. The filings come on the same day that a committee in the House of Representatives was to begin hearings into impeachment complaints against Marcos, accused of corruption tied to a spiraling scandal over bogus flood control projects. Under the constitution, an impeachment by the
Exiled Tibetans began a unique global election yesterday for a government representing a homeland many have never seen, as part of a democratic exercise voters say carries great weight. From red-robed Buddhist monks in the snowy Himalayas, to political exiles in megacities across South Asia, to refugees in Australia, Europe and North America, voting takes place in 27 countries — but not China. “Elections ... show that the struggle for Tibet’s freedom and independence continues from generation to generation,” said candidate Gyaltsen Chokye, 33, who is based in the Indian hill-town of Dharamsala, headquarters of the government-in-exile, the Central Tibetan Administration (CTA). It
China executed 11 people linked to Myanmar criminal gangs, including “key members” of telecom scam operations, state media reported yesterday, as Beijing toughens its response to the sprawling, transnational industry. Fraud compounds where scammers lure Internet users into fake romantic relationships and cryptocurrency investments have flourished across Southeast Asia, including in Myanmar. Initially largely targeting Chinese speakers, the criminal groups behind the compounds have expanded operations into multiple languages to steal from victims around the world. Those conducting the scams are sometimes willing con artists, and other times trafficked foreign nationals forced to work. In the past few years, Beijing has stepped up cooperation
