The most accepted theory of the origin of the universe is still the Big Bang. The theory proposes the universe started from a small singularity (the gravitational kind), then began to expand over the succeeding 13.8 billion years. Although this expansion has its own issues, a bigger question remains: what preceded the Big Bang?
Physicists have created a quantum atomic clock that uses a new design to achieve unprecedented levels of accuracy and stability. Its broad range of potential applications could even stretch to research into dark matter.
Two teams of astronomers have found a way to observe the presence of the missing matter connecting the galaxies in the universe. This discovery can improve our understanding of how galaxies were formed in the years following the Big Bang.
Dark matter and dark energy are two of the greatest mysteries in the cosmos. We're fairly certain that both exist, yet their nature remains to be fully understood. Now, a team of astronomers suggests that dark energy may be a dynamical field.
Previously, it has been cost-intensive, inefficient, and harmful to the environment to create hydrogen fuel. But a new technique developed at the University of Central Florida efficiently creates hydrogen fuel from seawater.
Aviation giant Boeing has acquired Aurora Flight Sciences in an effort to speed up development of their autonomous electric aircraft. Boeing joins other companies, like Airbus, in welcoming the self-flying vehicle revolution.
Technically speaking, Moore’s law began as a simple observation: In 1965, Intel co-founder Gordon Moore noticed that in the emerging industry of computer electronics it seemed that the number of transistors per square inch on integrated circuits seemed to consistently increasing (roughly doubling) each year.
Despite what their parents might have taught them, physicists aren’t always the best at sharing with others. Yet a public release of data from the Large Hadron Collider (LHC) back in 2014, has already yielded exciting results: for one, it’s allowed physicists to confirm that a fundamental equation correctly describes what happens in the real world.
The first direct detection of gravitational waves on 14 September 2015 proved that massive objects can ripple the structure of space, verifying a key prediction of Albert Einstein’s general theory of relativity. The second detection, made on 26 December 2015 and announced this June, firmly established gravitational waves as a new window to the Universe.
Researchers from the Chinese Academy of Science and the Austrian Academy of Sciences have conducted the first quantum video call using the Micius satellite launched in 2016. The call was between Beijing and Vienna, and was completely unhackable.
A team of researchers from the U.S. and Russia have discovered a way to make aluminum that's lighter than water. The team accomplished the task using computational modeling, and replaced the carbon atoms in a diamond with aluminium tetrahedron.
Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron’s function and how it coordinates with other cells in the brain. However, performing this kind of recording is extremely difficult, so only a handful of neuroscience labs around the world do it.
For years, computer users have been told they should have complicated passwords, including numbers, punctuation marks and other symbols, and upper- and lowercase letters. Despite those being hard to remember, people were told not to write their passwords down, and forced to make up new ones quite frequently. Users dutifully complied – by capitalizing the first letter of their passwords, adding a “1” or their birth year, or perhaps ending their password with an exclamation point.
You’ve probably decided the intended question is: “What has Donald Trump done now?”But how did you reach that conclusion? The word fragments could be part of many different words. You even expanded two almost identical fragments – “Don” and “don” – to different words – “Donald” and “done”.
The use of biofuels helps reduce human greenhouse gas emissions. That’s one reason why some petroleum companies offer petrol containing up to 10% ethanol (a biofuel). But if we are to have any real chance of avoiding catastrophic climate change, it is not enough to reduce our emissions; we must put the process into reverse.
