From History:
Meaning:
Breakthroughs often occur when conviction gives way to honesty.
3.
From History: 1842
In 1842, Christian Doppler wrote about the doppler effect in stars. It was first confirmed with sound in 1845, then with light in 1848. The big moment came in 1868 when, for the first time, we could tell which stars were coming and going.
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:
- Carl Sagan.
- circa 1980.
Meaning:
We are not separate from the universe—we are expressions of it, linked by matter, chemistry, and atoms.
6.

Meaning:
Change is the only form of permanence that exists—first glimpsed by ancient thinkers, and now woven into the fabric of modern science.
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.
Entanglement proves connection. It does not prove what that connection means. Quantum entanglement shows that particles can share linked states across distance.
Done. Refresh for another set.
