- What is gravity? - NASA
Newton's "law" of gravity is a mathematical description of the way bodies are observed to attract one another, based on many scientific experiments and observations The gravitational equation says that the force of gravity is proportional to the product of the two masses (m 1 and m 2), and inversely proportional to the square of the distance (r) between their centers of mass Mathematically
- Graviti - Data Platform to Accelerate AI and Machine Learning
Graviti accelerates data-driven innovation by improving productivity and achieving scalability for your machine learning projects or business analytics Discover hidden value in your unstructured data
- Matter in Motion: Earths Changing Gravity | NASA Earthdata
A new satellite mission sheds light on Earth's gravity field and provides clues about changing sea levels
- StarChild: Stars - NASA
Gravity causes the last of the star's matter to collapse inward and compact This is the white dwarf stage which is extremely dense White dwarfs shine with a white hot light but once all of their energy is gone, they die The star has now reached the black dwarf phase
- Gravity Gravitational Field - NASA Earthdata
Gravity is the field around physical bodies, such as planets, that draws objects toward its center Earth's gravitational field can be measured by orbiting satellites that can detect changes to it These variations are related to change or transportation of mass, which can provide information on ocean circulation, glacial melt, droughts, or geodesy
- Does the Sun move around the Milky Way?? - NASA
Yes, the Sun - in fact, our whole solar system - orbits around the center of the Milky Way Galaxy We are moving at an average velocity of 828,000 km hr But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way!
- Earthdata Search | NASA Earthdata
Earthdata Search enables data discovery, search, comparison, visualization, and access across NASA’s Earth science data holdings
- How do we know that dark matter exists? - NASA
The cluster does not behave as scientists would expect it to if only the visible matter is generating the gravity present in the cluster 'Dark matter' theory suggests that a huge amount of dark (invisible to direct observation) matter, interacting gravitationally with the normal, visible matter in the universe, exists
