Big Bang Theory and Hubble's Law
What was the name of the universe theory formation?
The Big Bang
Why is there no observational evidence supporting the existence of white holes?
There is no observational evidence for white holes because none have been detected in space.
What's the name of the first black hole discovered?
Cygnus X-1
Did protons and neutrons form during the first seconds after the creation of the universe?
Yes, protons and neutrons were created after minutes of cooling.
How was the universe created?
The universe exploded and then cooled as it expanded.
What is the main idea behind shockwave cosmology proposed by Smoller and Temple?
It suggests that the Big Bang was not a single point singularity but rather an explosion within a black hole, creating an expanding universe.
What is an effect of black holes?
Deform spacetime
What is a parallel universe?
A parallel universe is a universe with its own reality, history, rules of physics, and maybe other versions of us.
Who created the Hubble's Law and when?
Edwin Hubble in 1929
What is a black hole?
A black hole is an astronomical object with a gravitational force so strong that nothing, not even light, can escape it.
Mention the three types of black holes
Stellar, intermediate, and supermassive
What happened during the firsts seconds after the creation of the universe?
During the firsts seconds of the bing bang, the universe was extremely hot and dense.
What is Hubble's Law about?
Hubble's law states that galaxies are moving away from each other at velocities proportional to their distances.
How many types of black holes exist?
3 types of black holes
When was Einstein's theory published?
1915
When did the Big Bang happen?
Some 13.7 billion years ago.
Mention the Hubble's Law formula
v = H₀ × d
How does the concept of a white hole differs from the concept of big bang according to general relativity?
The Big Bang is a cosmological event describing the universe's expansion from an initial hot, dense state, while white holes are theoretical, time-reversed versions of black holes.
What is the process of gravitational attraction called?
Spaghettification
What means: "H₀"?
It is the Hubble's constant.
