10 random key ideas.
1.
Remember, all your ideas start as speculation. Even Einstein’s theory of relativity began as an irrational idea: untested, uncertain, and waiting for reality to answer back.
2.
From History:
Einstein taught us that mass and energy are two forms of the same thing and that gravity is better understood as the curvature of spacetime that guides motion.
3.
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.
4.
Time exists as part of spacetime, but the passing of time is how we experience and measure change: objects moving, positions shifting, events unfolding, and clocks counting those events.
5.
Article summary:
ΛCDM remains the leading cosmological model because our current best measurements indicate gravity is not strong enough to stop the universe’s expansion.
6.
Emptiness belongs to philosophy. Physics reveals a universe where a true voids do not exist.
7.
Gravity is universal: every mass influences every other mass, no matter how small.
8.
Physicists often talk about the idea that the universe exploded from nothing in a singularity, that idea is more philosophical than scientic. The universe’s expansion is scientific, the singularity itself remains speculative.
9.
Time entropy is the arrow of time seen through irreversibility: causes leave traces, energy spreads, and the past becomes written while the future remains open.
10.
When thinking about the speed of light, remember that gravity never waits. Light can be delayed by matter, but gravity propagates freely through spacetime.
