Does the Block Universe of Physics Mean Time is an Illusion?
I have written many Insights (and coauthored an entire book) explaining how the puzzles, problems, and paradoxes of modern physics can be attributed to…

A Principle Explanation of the “Mysteries” of Modern Physics
All undergraduate physics majors are shown how the counterintuitive aspects ("mysteries") of time dilation and length contraction in special relativity…

LHC Relativistic Energies and Time Dilation at 3.5–14 TeV
Large Hadron Collider and proton energies
The Large Hadron Collider has produced collisions at 7 TeV. For collisions at 7 TeV, each proton must be ramped…

Learn Relativity Using the Bondi K-calculus
Although Special Relativity was formulated by Einstein (1905), and given a spacetime interpretation by Minkowski (1908) [which helped make special relativity…

Relativity Variables: Velocity, Doppler-Bondi k, and Rapidity
Traditional presentations of special relativity place emphasis on "velocity", which of course has an important physical interpretation... carried over…

Learn About Relativity on Rotated Graph Paper
This Insight is a follow-up to my earlier tutorial Insight (Spacetime Diagrams of Light Clocks).
I gave it a different name because I am placing more…

Learn About Spacetime Diagrams of Light Clocks
We demonstrate a method for constructing spacetime diagrams for special relativity on graph paper that has been rotated by 45 degrees. Many quantitative…

A Geometrical View of Time Dilation and the Twin Paradox
Based on the number of questions we receive on the topic at Physics Forums, there is a lot of confusion in the general public about how time dilation works…

Blockworld and Its Foundational Implications: Time Dilation and Length Contraction
This is the first in a 5-part series of Insights that will introduce blockworld (aka "block universe”) and use it to address a puzzle…

Time Dilation & Redshift of Schwarzschild Black Holes
Time dilation near a Schwarzschild black hole
The following is an overview of the time-dilation and gravitational-redshift effects of a static (Schwarzschild)…

Learn About Neutrino Masses and Speed
It was hard to miss the 2011 OPERA neutrino speed measurement that indicated superluminal neutrino speeds (and turned out to be a measurement error), but…
