Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

A pair of scientists from the UK recently published a pre-print research paper discussing the theory of a universe with no beginning. Imagine it: our universe has always existed. The Big Bang either ...

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

In his discussion of accelerated motion on page 60 of "The Meaning of Relativity," Albert Einstein made an approximation that allowed him to develop the theory of relativity further. Einstein ...

Since 2007, physicist Leonard Susskind has regularly delivered a lecture series called the Theoretical Minimum, on the foundations needed to study different areas of ...

It is a matter for celebration when two illustrious theoreticians such as Kip Thorne and Roger Blandford provide an in-depth description of the fundamentals of classical physics. Modern Classical ...

Discoveries in science do not just revolutionize science, but can also exert a deep and lasting impact on the visual arts and on literature. One famous example is the effect that Galileo’s telescopic ...
