Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

Machine learning models are designed to take in data, to find patterns or relationships within those data, and to use what ...

Quantum entanglement is one seriously long-distance relationship. Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter ...

Virtual particles exploit the natural fuzziness of the subatomic world, where if these ephemeral particles live briefly enough, they can also briefly borrow their energy from empty space. The haziness ...

Could global positioning systems become more precise and provide more accurate details on distances for users to get from ...

The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

Real particles are lumps of energy that can be "seen" or detected by appropriate instruments; this feature is what makes them ...

Another interesting consequence of relativity is that as time stretches out at high speeds, distances diminish. It’s hard to ...

This is the 74th closest star to the Sun, so pretty much a neighbor, but 18 light-years is still a very long way to borrow a ...

A journey describes the motion of an object over time. A journey can be represented using a distance-time graph. The graph will show when an object is moving and when it is stationary. The graph can ...
