(CNN) -- Uncertainty over the fate of missing Malaysia Airlines Flight 370 was further compounded Saturday by reports that two men whose names matched those on the passenger manifest had reported their passports stolen.

Malaysian authorities apparently did not check the stolen documents on an international law enforcement agency database, CNN has learned.

After the airline released a manifest of the 239 people on the plane, Austria denied that one of its citizens was on the flight as the list had stated. The Austrian citizen was safe and sound, and his passport had been stolen two years ago, Austrian Foreign Ministry spokesman Martin Weiss said.

Similarly, Italy's foreign ministry confirmed that no Italians were on the flight, even though an Italian was listed on the manifest. Malaysian officials said they were aware of reports that the Italian's passport was also stolen but had not confirmed it.

On Saturday, Italian police visited the home of the parents of Luigi Maraldi, the man whose name appeared on the manifest, to inform them about the missing flight, said a police official in Cesena, in northern Italy.

Maraldi's father, Walter, told police that he had just spoken to his son, who was fine and not on the missing flight, said the official, who is not authorized to speak to the media. Maraldi was vacationing in Thailand, his father said. The police official said that Maraldi had reported his passport stolen in Malaysia last August and had obtained a new one.

U.S. law enforcement sources, however, told CNN they've been told that both documents were stolen in Thailand.

North Rhine-Westphalia (, , commonly shortened to NRW) is the most populous state of Germany, with a population of approximately 18 million, and the fourth largest by area. Its capital is Dusseldorf; the largest city is Cologne. Four of Germany's ten largest citiesCologne, Dusseldorf, Dortmund, and Essenare located within the state, as well as the second largest metropolitan area on the European continent, Rhine-Ruhr.

North Rhine-Westphalia was formed in 1946 as a merger of the provinces of North Rhine and Westphalia, both formerly parts of Prussia, and the Free State of Lippe. It makes up almost a quarter of the population and a quarter of the economy of Germany.

The first written account of the area was by its conqueror, Julius Caesar, the territories west of the Rhine were occupied by the Eburones and east of the Rhine he reported the Ubii (across from Cologne) and the Sugambri to their north. The Ubii and some other Germanic tribes such as the Cugerni were later settled on the west side of the Rhine in the Roman province of Germania Inferior. Julius Caesar conquered the tribes on the left bank, and Augustus established numerous fortified posts on the Rhine, but the Romans never succeeded in gaining a firm footing on the right bank, where the Sugambri neighboured several other tribes including the Tencteri and Usipetes. North of the Sigambri and the Rhine region were the Bructeri.

(CNN) -- It's a number that even astrophysicist Neil deGrasse Tyson is having a hard time wrapping his brilliant mind around.

His Christmas Day tweet commemorating the birthday of Isaac Newton was retweeted more than 69,000 times as of this writing, making it the most popular of his Twitter career so far -- and, arguably, his most controversial.

"On this day long ago, a child was born who, by age 30, would transform the world. Happy Birthday Isaac Newton b. Dec 25, 1642," the StarTalk host tweeted.

He followed it up with a nod to the commercialization of Christmas: "Merry Christmas to all. A Pagan holiday (BC) becomes a Religious holiday (AD). Which then becomes a Shopping holiday (USA)." By then, he was on a roll. Earlier in the day, he tweeted, "QUESTION: This year, what do all the world's Muslims and Jews call December 25th? ANSWER: Thursday."

His comments drew criticism and name-calling from various corners of the internet. "Overly reductive, deliberately cynical and unnecessarily provocative," one person said on Twitter.

Another accused him of "trolling Christmas today to show you how smart he is."

Tyson's response to the controversy? "Imagine a world in which we are all enlightened by objective truths rather than offended by them."

Later Friday, Tyson pondered "My Most Retweeted Tweet" in a Facebook post. He did not defend or disavow his comments. Instead, in true scientific form, he attempted to quantify their popularity compared to previous tweets.

"My sense in this case is that the high rate of re-tweeting, is not to share my enthusiasm of this fact, but is driven by accusations that the tweet is somehow anti-Christian," he wrote. "If a person actually wanted to express anti-Christian sentiment, my guess is that alerting people of Isaac Newton's birthday would appear nowhere on the list."
