A Tipler cylinder, also called a Tipler time machine, is a hypothetical object theorized to be a potential mode of time travel—although results have shown that a Tipler cylinder could only allow time travel if its length were infinite or with the existence of negative energy.
The chronology protection conjecture is a hypothesis first proposed by Stephen Hawking that laws of physics beyond those of standard general relativity prevent time travel—even when the latter theory states that it should be possible (such as in scenarios where faster than light travel is allowed).

The Debye–Waller factor (DWF), named after Peter Debye and Ivar Waller, is used in condensed matter physics to describe the attenuation of x-ray scattering or coherent neutron scattering caused by thermal motion. [1] [2] It is also called the B factor, atomic B factor, or temperature factor.
Many Americans are counting on their tax refunds to help make ends meet. Here's when you can expect yours.
Travel time reliability has been increasingly recognized as a key performance indicator for transportation roadways and transport systems, which exerts a strong influence on the stakeholders in transportation networks, including users (travelers), service providers, planners, and managers. This has stimulated research into the development of ...
A U.S. judge will consider on Monday the fate of President Donald Trump's buyout offer to two million federal workers as Trump presses ahead with an unprecedented effort to dismantle government ...
Eating too fast, talking while you’re chowing down, not chewing enough or munching on dry foods might cause difficulty swallowing from time to time, doctors say.
