Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

See how a simple DIY gravity battery experiment led to unexpected outcomes. This project shows creativity and experimentation ...

The secret to directly detecting dark matter might be blowin’ in the wind. The mysterious substance continues to elude scientists even though it outweighs visible matter in the universe by about 8 to ...

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.
