What is the longest running TV show? There are a number of ways to approach this question. The first is the most obvious: duration or number of years. Meet the Press is the clear winner here. It premiered in 1947 and is still airing today, which means it’s been around for a staggering 68 years and counting. Even if you define “longest running” in terms of actual minutes on the air, Meet the Press still probably comes out on top.

No party is complete without a round of this forever-loved game, because nothing is better than getting down into the dirty details and embarrassing all your friends. While truth or dare has been around for ages, the questions have not really changed. Everyone is going to hear the classic “Who is your crush?

On one side of the field, we have Hollywood starlets, activist-parents of autistic children, and a rash of opportunistic politicians – all lining up to condemn the nation’s immunization program for young children. Over the last decade, this fervent coalition has convinced more and more parents that routine childhood injections against diseases like measles and mumps are causing autism and should be avoided at all costs. As a result, child vaccination rates are declining and infectious outbreaks are increasing at an alarming pace.

Earthquakes are a natural disaster that occurs because of the sudden release of energy in the Earth’s crust. Seismic waves are created and the tremors that are felt can be measured by seismometers. Earthquakes are measured based on their magnitude (the Richter scale). There have only been a couple that registered over a magnitude of 9.0 on the seismometer. An earthquake with a magnitude greater than 9.0 is an extreme natural disaster and are very rare.

Although widely used by government agencies, especially in law enforcement and intelligence, polygraph techniques have been repeatedly discredited as pseudoscience by the scientific community. Polygraphs are based on the simple notion that most people become physiologically ‘aroused’ in response to their own lies. The typical arousal response includes increased heart rate, respiration, blood pressure, and skin conductivity.

**Snipers have always held a place of esteem and fascination in popular culture, perhaps because of the amazing level of precision and patience involved with long-distance kills. ** While sniping has a long and illustrious history, the range and precision of weapons has improved with advancing technology in recent years, enabling longer shots.

Black holes are undoubtedly one of the most bizarre and intriguing phenomena in the universe. We’ve only known about them for about a hundred years, though their existence has been postulated since the 18th century. What is a black hole, anyway? What really happens when you fall into one? Astronomers and physicists have been wrestling with black hole mysteries for years, but a growing consensus has emerged on a number of points.

On the whole, American cities have become much safer. After years of declining rates of violent crime, they are now about as safe as they were in the 1960s. But violent crime is still a problem in lots of cities. And while the gap between urban and suburban crime rates has narrowed, suburban spaces still tend to be safer than urban places. Echoing that trend, it seems the safest cities in America are predominantly suburbanized middle-tier cities with moderate population density.
