10 random key ideas.
1.
Quantum tunneling happens when a particle is found beyond an energy barrier it should not cross under classical physics.
2.
Quote:
- Carl Sagan.
- circa 1980.
Meaning:
Wisdom begins with perspective. We are are expressions of the universe. The particles making up your body are ancient, borrowed for a time from a universe much older than you.
3.
From History: 13.8 Billion Years Ago: First Millisecond
In the first fraction of a second, the universe cooled enough for the electromagnetic and weak forces to split, setting the stage for stable particles.
4.
Antimatter moves forward in time like normal matter. The “backward in time” idea is a useful mathematical interpretation, not an observed physical fact.
5.
Quote:
- Heraclitus.
- 500 BCE.
Meaning:
Change is the only form of permanence that exists—first glimpsed by ancient thinkers, and now woven into the fabric of modern science.
6.
From History: Jul 1632
The laws of physics work the same for all observers moving at a constant speed. There is no absolute state of rest.
7.
Physics allows time to bend forward, but all observations so far show that causality is preserved.
8.
Quote:
- Max Planck.
- circa 1900.
From History:
Meaning:
Breakthroughs often occur when conviction gives way to honesty.
9.
From History: 13.8 Billion Years Ago
When we trace the universe backward, our equations point to an unimaginably hot, dense beginning — not a confirmed object, but the mysterious edge where current physics breaks down.
10.
In shaping modern cosmology, Galileo articulated the relativity principle in 1632, Newton made gravity universal in 1687, and Einstein revealed gravity as the curvature of spacetime in 1915.
