Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that ...

(Phys.org)—There are many experiments that physicists would like to perform on antimatter, from studying its properties with spectroscopic measurements to testing how it interacts with gravity. But in order to perform these ...
(PhysOrg.com) -- Seventeen minutes may not seem like much, but to physicists working on the Antihydrogen Laser Physics Apparatus (ALPHA) project at the CERN physics complex near Geneva, 1000 seconds is nearly four orders ...
(PhysOrg.com) -- In 1932, scientists observed the first antimatter particle, a positron (or antielectron). Since then, scientists have observed heavier and heavier states of antimatter: antiprotons and antineutrons in 1955, ...
Italian researchers using data from the satellite PAMELA have proven that theories showing there ought to be a ring of antiprotons encircling the Earth due to cosmic rays colliding with nuclei in the upper atmosphere are ...
The search goes on. No difference in protons and antiprotons have yet been found which would help to potentially explain the existence of matter in our universe. However, physicists in the BASE collaboration at the CERN research ...

The atoms that make up ordinary matter fall down, so do antimatter atoms fall up? Do they experience gravity the same way as ordinary atoms, or is there such a thing as antigravity?

By the logic of science, things simply shouldn't exist. The best scientific minds of several generations have reasoned that shortly after the Big Bang created the universe, matter and antimatter should have wiped each other ...

We learn it at high school: Release two objects of different masses in the absence of friction forces and they fall down at the same rate in Earth's gravity. What we haven't learned, because it hasn't been directly measured ...

(PhysOrg.com) -- The 25-year-old Tevatron particle accelerator in the US will end its operations in September this year since no funds are available to extend its life for three more years.
