Gravity was known to humans long before the present-day picture of four fundamental interactions was formed. The nature of gravity is fundamental to our understanding of our solar system, the galaxy and the structure and evolution of the Universe. It was Newton who first understood that gravity not only dictates the fall of apples and all bodies on Earth, but also planetary motion in our solar system and the sun itself are govern by the same physical principles. On the larger scales the effects of gravity are even more pronounced, guiding the evolution of the galaxies, galactic clusters and ultimately determining the fate of the Universe. Presently the Einstein’s general theory of relativity is a key to the understanding a wide range of phenomena, spanning from the dynamics of compact astrophysical objects such as neutron stars and black holes, to cosmology, where the Universe itself is the object of study. Its striking predictions include gravitational lensing and waves, and only black holes have not yet been directly confirmed.
LURCH said:So, gravity waves have been directly confirmed? That is news to me, as well.I've been following LIGO, but haven't checked in lately. Last I heard, there were still no definitive results.
It's great isn't it.qwerty2x said:I like the rap!
The best thing science has ever done is subjective and can vary from person to person. Some may argue that it is the discovery of electricity or the invention of vaccines, while others may say it is the development of space exploration or the understanding of DNA. Ultimately, science has made countless advancements and discoveries that have greatly improved our lives.
Science has made our lives better in countless ways. It has improved our health through medical advancements, increased our lifespan, and provided us with a better understanding of the world around us. Science has also made everyday tasks easier and more efficient through the development of technology and inventions. Additionally, it has helped us address and combat global issues such as climate change and pandemics.
Science plays a crucial role in society by providing us with the knowledge and tools to improve our lives and the world around us. It helps us understand the natural world, develop new technologies and treatments, and address pressing global issues. Science also promotes critical thinking, problem-solving, and innovation, which are essential for progress and development.
One example of a significant scientific achievement is the development of the polio vaccine. This vaccine, discovered by Dr. Jonas Salk in 1955, has saved millions of lives and effectively eradicated the disease in many countries. It is considered one of the greatest public health achievements in history and a testament to the power of science to improve and save lives.
The future of science is boundless, and its impact on society will continue to grow. Advancements in fields such as biotechnology, artificial intelligence, and renewable energy will transform our lives and address global challenges. However, it is crucial for science to be used ethically and responsibly to ensure its positive impact on society and the environment.
