What keeps a ship afloat
By: Cyn P.
Have you ever thought why a small stone sinks in water while a big ship can stay afloat in the sea? Well, physics can explain this. In 212 BC, Archimedes who was a Greek mathematician, physicist, engineer, inventor and astronomer discovered a principle, now known...
How to create a warp drive
By: D. Vogt
A warp drive is a theoretical type of space propulsion drive which would allow spacecraft to travel faster than light by somehow warping or distorting spacetime around them. Science fiction writers, and certain futurism-oriented physicists, envision the warp drive as an important building block for...
What is dark matter and dark energy
By: D. Vogt
Our scientific understanding of the universe has had more than a few upheavals over the past century, beginning with revolutionary advances in theories of relativity and quantum physics. However, two puzzles continue to defy easy explanation: why regions around the universe seem to have more...
Understanding the second law of thermodynamics
By: D. Vogt
The second law of thermodynamics states that the entropy of a closed system always increases over time - or, in layman's terms, all things decay. It is one of the four fundamental laws of thermodynamics, and the most important for understanding the future energy state...
What is at the center of a black hole?
By: Lijun He
One of the greatest challenges facing our physicists today are the mysteries of black holes. After being coined by John Wheeler in 1967, the phrase ‘black hole’ has spread throughout the planet. But yet we know very little about black holes. Black holes are...
Physics: Hawking proclaims 'Time travel will exist'
By: D. Vogt
For decades, time travel has been one of the most common tropes of popular science fiction. Today, a growing number of physicists and cosmologists are beginning to suggest that it might eventually become a reality - although not necessarily the casual back-and-forth phenomenon we saw...
The role of the sun in time travel theory
By: D. Vogt
In some popular science fiction, in which time travel is possible, the Sun - or some other star - is said to make possible an unusual and perhaps even controlled method of backwards time travel. This usually involves the intersection between the massive energy or...
By: Allen Gates
Conduction is a type of heat transfer that deals with contact between to objects. Each object has an initial temperature that is different than the other, but when the two objects come in contact over a period of time they reach an equilibrium temperature. In...
Stephen Hawking warns about aliens and insults the human race
By: D. Vogt
Earlier in 2010, the famous physicist Stephen Hawking made headlines with the controversial remark that our search for extra-terrestrial intelligence is putting Earth at too great a risk, since it may provoke an unwanted first contact with hostile aliens. In his popular television documentary series...
The real meaning of E=MC2
By: Christyl Rivers
The Real Meaning of E=MC2 is Oneness, Relativity, Connection, and Hope Oneness: That Energy can be equal to mass, times the speed of light, squared, is an amazing leap of science. Einstein, even by 1905, showed clear signs of genius. He is now a cultural...
