Science and technology breakthroughs can always bring comfort and hope: some can bring big surprises; some become life's small fortunes, so that people are full of hope for a better tomorrow. At the end of the year, the US "Popular Science" website combed a number of technological breakthroughs that were unforgettable in 2016.
Scientists successfully detected gravitational waves
On February 11 this year, American scientists announced that they used the laser interference gravitational wave observatory (LIGO) detector to detect the gravitational wave signals of the two black holes merged 1.3 billion years ago on September 14, 2015. According to scientists' estimates, the masses of the two black holes before the merger are equivalent to 36 and 29 solar masses respectively, and the combined total mass is 62 solar masses, which is equivalent to the energy of three solar masses during the merger. The form of the wave is released.
Gravitational waves are a kind of space-time 涟漪, and celestial bodies such as black holes and neutron stars may generate gravitational waves during collision. One hundred years ago, Einstein's general theory of relativity predicted the existence of gravitational waves. It was also the last missing piece of the puzzle in Einstein's general theory of relativity. The discovery of gravitational waves will open a new era in astrophysics, allowing scientists to study the universe from a new perspective.
Everyone can play virtual reality
Although a more powerful (and certainly more expensive) computer is needed to achieve a high-quality virtual reality experience, Sony's virtual reality helmet can be used as an accessory for PlayStaTIon 4, and users do not need an engineer degree to install and set up. . Because this helmet is simple to use, plug and play; and the price is relatively close to the people, it is considered to be the most likely to win the battle of virtual reality living room.
WhatsApp encrypts chat content
In April of this year, affected by Apple’s mobile phone leaking personal information, mobile phone chat tool WhatsApp said that its 1 billion users will start end-to-end chat data encryption by default, which means that the other party can only see the chat content when authorized. Authorized cybercrime groups, hackers, government agencies, and even WhatsApp itself do not see chat content.
The solar system or the 9th largest planet
The solar system originally had "nine planets." However, since Pluto was delisted in 2006, the solar system has only "eight planets."
However, things may change again now. In January of this year, scientists used mathematical calculations and computational simulations to seem to find signs of the existence of another large planet hidden in the solar system. This should be a gaseous giant planet equivalent to Neptune, 10 to 20 times the distance from the Sun to the Sun. If this discovery can be confirmed, the solar system will return to the "nine planets" era.
Solar aircraft completes the manned global tour
At 4 am on July 26, Bertrand Picard and Andrei Boschberg landed "Sunshine Power 2" in Abu Dhabi, the capital of the United Arab Emirates, and completed the first use of fossil fuels in human history. A manned global flight that relies on solar energy.
They took off from Hawaii on March 9, 2015, spanning 4 continents, flying about 558 hours, with a cumulative journey of 43041 kilometers, totaling about 23 days in the sky, using a total of 11,655 kWh of solar energy. The aircraft will be used to test more solar technology and to develop solar drones.
The ozone hole over the Antarctic is healing
The ozone layer can block too much ultraviolet light from entering the earth, but due to human activities, the ozone layer begins to crack and is extremely harmful to humans. In mid-July of this year, the research team led by Susan Solomon, a professor of atmospheric chemistry and climate science at the Massachusetts Institute of Technology, published in the journal Science, pointing out that due to restrictions on the use of chlorofluorocarbons (CFC) gases and changing weather patterns, Evidence shows that the ozone hole over the Antarctic is healing. They believe that the hole has actually shrunk by more than 4 million square kilometers; the depth of the hole has also begun to become shallow.
Although CFC products were completely discontinued in the 1990s, they have a service life of 50 to 100 years. Therefore, the chlorine molecules produced in the 1970s and 1980s have survived in the atmosphere. Therefore, scientists estimate that the ozone layer will not be completely repaired until around 2050-2060.
Beautiful children can sue the government for climate warming
As the global warming situation worsens, our next generation may have to endure the melting of glaciers, the growing dryness of farmland, frequent wildfires and more severe storms. To this end, 21 young plaintiffs between the ages of 9 and 20 in the United States sued President Obama, the fossil fuel industry and other federal government agencies, accusing them of violating the plaintiff's constitutional rights by refusing to take action on global climate change.
Both the US government and the US oil organization have asked the court to dismiss the lawsuit, but Oregon District Court Judge Ann Aiken claims that human factors contribute to climate change is an undisputed fact that climate change threatens the basic constitutional rights of the plaintiff's life and freedom. Therefore, these people are given the right to sue the government.
