CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

The nature of dark matter is largely unknown, but it is thought to have mass, which influences particle interactions in the universe through gravity. Dark matter may not interact much with visible ...

Understanding why matter and antimatter behave differently is key to understanding why there is a universe at all. Now physicists have discovered the latest example of a subtle difference between the ...

A new space telescope will soon peer into the darkness of ‘near space’ (within a few thousand light years of Earth) to seek answers related to the field of high-energy astrophysics Peering into ...

Have you ever stood by the sea and been overwhelmed by its vastness, by how quickly it could roll in and swallow you? Evidence suggests that we are suspended in a cosmic sea of dark matter, a ...
