UT nuclear physicist Geoffrey Greene says physicists need to know the neutron’s lifetime in order to calculate the relative abundances of hydrogen and helium that would have been produced during the universe’s first few minutes, according to Quantra and Wired magazines.
Superconducting technology has given us highly-detailed medical imaging, particle accelerators, and high-speed trains, but exactly what gives rise to this property is still a mystery.
Last month, astronomers wowed the world when they announced that they had seen two neutron stars merge, apparently creating heavy elements such as gold and platinum and spewing them into space.
In October, scientists announced the first observation of a cosmic event with both gravitational waves and light. As reported by Inside Science, the detection of this event with both gravitational waves and light is an example of what scientists call multi-messenger astronomy. UT astrophysicist Mike Guidry says, “Multi-messenger events are really the holy grail, with
UT’s Society of Physics Students will host its third annual pumpkin drop at 5:30 p.m. Friday, October 27.
It was an event 130 million years in the making yet marked by the speed of light. On October 16 scientists announced they had, for the first time, detected both gravitational waves and light resulting from the collision of neutron stars. The discovery figures heavily into the work of several UT physicists.
Science magazine featured as its cover story the neutrino discovery of a team of scientists including Yuri Efremenko, a professor of physics. After more than a year of operation at Oak Ridge National Laboratory, the COHERENT experiment, using the world’s smallest neutrino detector, found a big fingerprint of the elusive, electrically neutral particles that interact only weakly
UT astronomer Paul Lewis explains to WBIR what you may have seen if you took any photos during the solar eclipse.
Are space and time intertwined? Is light a particle or a wave? What are the building blocks of the universe?
This summer, national and local media have drawn upon the expertise of UT faculty members to learn about this phenomenon and to help the public prepare to view it safely.
Several local outlets highlighted a UT aerospace workshop that showed educators fun ways to bring STEM education into the classroom through hands-on activities.
T minus 18 days. On Monday, August 21, a total solar eclipse—when the disk of the moon completely covers the sun—will be visible in the United States along a path from central Oregon through Tennessee and on to South Carolina.
