“In a time of deceit telling the truth is a revolutionary act. If liberty means anything at all, it means the right to tell people what they do not want to hear.”
― George Orwell

What Is Happening “Now” Is Relative
In special relativity, the statement that two events happened at the same time is meaningless.
By Sabine Hossenfelder — BIG THINK
- We always see things as they looked a little bit earlier, but we don’t normally notice this in everyday life. It gets even weirder, though.
- In special relativity, the statement that two events happened at the same time is meaningless.
- Every event is “now” for someone.

Four Thousand Weeks
time management for mortals
By Oliver Burkeman
The average human lifespan is absurdly, insultingly brief. Assuming you live to be eighty, you have just over four thousand weeks.
Nobody needs telling there isn’t enough time. We’re obsessed with our lengthening to-do lists, our overfilled inboxes, work-life balance, and the ceaseless battle against distraction; and we’re deluged with advice on becoming more productive and efficient, and “life hacks” to optimize our days. But such techniques often end up making things worse. The sense of anxious hurry grows more intense, and still the most meaningful parts of life seem to lie just beyond the horizon. Still, we rarely make the connection between our daily struggles with time and the ultimate time management problem: the challenge of how best to use our four thousand weeks.
How Do We Know That Time Exists?
By CORDIS — Phys.Org
The alarm goes off in the morning. You catch your morning train to the office. You take a lunch break. You catch your evening train back. You go for an hour’s run. Eat dinner. Go to bed. Repeat. Birthdays are celebrated, deaths commemorated. New countries are born, empires rise and fall. The whole of human existence is bound to the passing of time.
But we can’t see it and we can’t touch it. So, how do we know that it’s really there?
Portal Opens to Extra Time Dimension
just what we need, eh?
By Zeeya Merali — Scientific American
Opening a portal to an extra time dimension—even just a theoretical one—sounds thrilling, but it was not the physicists’ original plan.
Time Isn’t Simply Just Another Dimension
By Ethan Siegal — BIG Think
We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!
- According to Einstein’s General Relativity, matter and energy curve the fabric of spacetime, and that curved spacetime determines the motion of matter and energy.
- But while spacetime itself is four dimensional, it can be decomposed into three spatial dimensions and one time dimension.
- Even though we understand the mathematics governing them magnificently, time has some fundamental differences from every other dimension; here’s what everyone should know.
