The phrase "a tiny universe of a second" is correct and usable in written English.
It can be used to describe a brief moment in time that feels expansive or significant, often in a poetic or metaphorical context.
Example: "In that tiny universe of a second, everything changed, and I realized the depth of my feelings."
Alternatives: "a fleeting moment" or "a brief eternity".
There is a tiny universe of potential customers who would want access to financial data two seconds ahead of others.
"Epic," a fairy tale about a tiny universe of creatures who protect the forest, has many virtues.
Inflation is the leading theory to explain the first instant of the universe, a tiny fraction of a second after the Big Bang.
The patterns, astronomers said, were probably created by microscopic processes -- energy fluctuations at the quantum scale -- that were at work when the universe was a tiny fraction of a second old and smaller than a human fist.
The original inflationary model of the universe proposed that when our universe was only a tiny fraction of a second old, it underwent a brief, but stupendously accelerated expansion.
Cosmic inflation describes a phase lasting a tiny fraction of a second in the universe's existence, in which the universe expanded at a faster-than-light speed from a speck much, much smaller than an atom to about the size of a grapefruit.
In this talk, I will explain how we can use measurements of the Cosmic Microwave Background and the large-scale structure of the universe to reconstruct the detailed physics of much earlier epochs, when the universe was only a tiny fraction of a second old.
But those numbers, while astronomical, are finite, and don't give us any information about what happened in the Universe prior to the last tiny-fraction-of-a-second of inflation.
In March, the BICEP2 collaboration announced that it had found evidence of cosmic inflation – a violent expansion of the universe that occurred a tiny fraction of a second after the Big Bang, 13.8 billion years ago.
The theory goes that a tiny fraction of a second after the universe came into being it underwent a period of expansion, driven by a mysterious dark energy, which then initiated the hot big bang and provided all the stuff of the universe, including the stars, the planets and us.
What would you see if you somehow went to the time just a tiny fraction of a second earlier than when the Universe was at its highest energies, hot and dense, and full of matter, antimatter and radiation?
