What was the size and temperature of the universe before the Big Bang?
Protons and neutrons began to form. The temperature of the universe was around 10^32 Kelvin. 3 minutes after the Big Bang – Protons and neutrons began to come together to form the nuclei of simple elements. The temperature of the universe was still incredibly high at about 10^9 Kelvin.
How big was the object that caused the Big Bang?
The Big Bang theory can be summarized thusly: At one time, the entire universe — everything you know and love, everything on the Earth and in the heavens — was crushed into a trillion-Kelvin ball about the size of a peach. Or apple. Or small grapefruit.
What triggered the Big Bang?
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
What was the first thing in the universe?
The Big Bang is thought to have kick-started the universe about 13.7 billion years ago. At first, the universe was too hot and dense for particles to be stable, but then the first quarks formed, which then grouped together to make protons and neutrons, and eventually the first atoms were created.
What is the coldest thing in the universe?
However, the coldest natural spot in the Universe currently is the Boomerang nebula, which resides 5,000 light-years away from us. Its temperature is measured to be 1 Kelvin or -272.15 degrees Celsius.
What is the fastest thing in the universe?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.
Will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
Does nothingness exist?
There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing.
