It has been estimated through the use of telescopes and gravitational methods that there are 200-300 billion stars in our galaxy. It has also been estimated through the use of deep space telescopes that there are 100s of billions of galaxies.Given that there 200...

Is the Universe really expanding?The currently accepted big bang theory is based on the idea that the Universe is expanding. Extrapolating backwards gives us a time when everything was compressed into a singularity, and something had to start the expansion: a big bang.The...

The United Nations General Assembly agreed in 2005 to a resolution to establish a Decade of Contact and diplomatic relations with extraterrestrials. While this sounds encouraging, little has been done since then.On Dec. 18, 1978, the UN voted to "take appropriate steps to coordinate...

The Drake Equation is a large and fairly vague mathematical system for working out how many other extra-terrestrial life forms there are in the universe that have reached a recognised level of civilization. That is not only other races but ones that meet specific criteria...

The clock paradox is more often referred to as the twin paradox. It, like all paradoxes in science, comes about due to a lack of applicability of a theory to a particular experiment.The twin paradox is based on the verified fact that the faster...

Will humans one day populate other planets? I have little doubt of that, though its going to take a while yet. But some people seem to see this as a solution to the population problem on Earth. This is simply absurd.The problem is the...

Gravity is a force of interaction between particles contained within the nucleus of an atom. It acts like a magnetic force in which the particles have an attraction for one another. The particles are one of the components of the nucleus of an atom...

The easiest way to actually determine the temperature of liquid nitrogen is with a constant pressure gas thermometer (we'll use CPGT for an abbreviation). This is also a method useful for determining absolute zero (see other articles regarding this temperature.A CPGT is a narrow...
