The scientific community believes that their discovery will ensure them a Nobel Prize.
For years, scientists were striving to find facts proving the existence of gravitational waves. Almost a century after Einstein’ exposition of gravity, specialists detected waves for the first time and revealed them to the world as a short chirp sound. Such a sound resulted from the collision of two supermassive black holes that are 1.3 billion light-years away from the Earth.
Scientists say that when a body moves round a black hole, the energy produced in form of gravitational waves is six times as powerful as the energy generated from thermonuclear reactions.
Of course, it is our up-to-date technologies that allowed us to detect and hear gravitational waves. In 2011, gravitational wave 'hunters' were reinstalled. Advanced LIGO is four times as sensitive as the previous incarnation. It is the largest apparatus on our planet with 4-km arms.
The devices are constructed to detect a wave going through our planet as a result of a black hole merger. Green light in the picture is a wave.
LIGO (Advanced Laser Interferometer Gravitational-wave Observatory) is actually two facilities, one in Louisiana and the other in Washington state; and both of them detected these waves.

This month, the price of Bitcoin has soared to a record $89,000. Despite its constant volatility, BTC remains the most promising cryptocurrency since its debut in 2009. Many early investors who believed in Bitcoin's potential are now reaping the rewards of their foresight. Let's take a look at today's wealthiest crypto enthusiasts
Economic inequality remains one of the most pressing issues in today's world. To measure the gap between the rich and the poor in each country, the Gini index is used. This coefficient reflects how income is distributed within a society: the closer the index is to 100, the greater the inequality. Let's explore which countries currently have the highest Gini index values
This year has been pivotal for Bitcoin, the world's leading cryptocurrency. One of the key milestones was the approval of Bitcoin spot ETFs by the US Securities and Exchange Commission. In April 2024, Bitcoin also experienced a halving event, which is typically seen as a positive development for the digital asset. This year, the cryptocurrency is up 57%, and analysts remain optimistic about its future. However, they highlight four key factors that could influence Bitcoin's trajectory, both for better and for worse
