In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
What happened before the universe?
Prior to the Big Bang — yes, before the Big Bang — the universe underwent a breathtaking cosmic expansion, doubling in size at least 80 times in a fraction of a second. This rapid inflation, fueled by a mysterious form of energy that permeated empty space itself, left the universe desolate and cold.
What was the universe called before?
Georges Lemaître published a paper in 1927 that proposed the universe started out as a singularity and that the Big Bang led to its expansion [source: Soter and Tyson]. According to Einstein’s theory of relativity, time only came into being as that primordial singularity expanded toward its current size and shape.
What created the universe?
Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
When did time begin?
approximately 14 billion years ago
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
What existed before empty space?
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
Why does anything exist?
The reason for the existence of most of the things we encounter in our day-to-day lives can be explained quite easily: something caused it. Take your screen: it exists because someone created it. Take you: you exist because some people created you.
Can something be created from nothing?
So particle-antiparticle pairs can be created from “nothing”, that is from no particles to two particles, but energy must be provided, so these particles can be viewed as having been created from the energy.
Is the space infinite?
There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Who created God?
We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
Can the universe Create Itself?
To “create” one needs to exist to do it. So, nothing can create itself. The universe simply always existed. The stuff in it was in a hot dense state about 13.8 billion years ago, and, has been getting less hot and less dense ever since that…but, the universe itself cannot “not exist”.
How will the universe end?
In the unimaginably far future, cold stellar remnants known as black dwarfs will begin to explode in a spectacular series of supernovae, providing the final fireworks of all time. That’s the conclusion of a new study, which posits that the universe will experience one last hurrah before everything goes dark forever.
Does God exist outside of time?
The question of God’s relation to time has generated a great amount of theological and philosophical reflection. The traditional view has been that God is timeless in the sense of being outside time altogether; that is, he exists but does not exist at any point in time and he does not experience temporal succession.
Can u go back in time?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time!
Is time a illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock.
How long will the universe exist?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.
How big is the universe?
approximately 93 billion light-years
While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
Where did all matter come from?
Origins. In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.
Does nothingness exist?
Nothingness is subjective, because it only exists in our (objective) minds. Nothingness is an abstract concept, meaning it may or may not possibly exist. Logically though, if nothingness exists, no (i.e. not any) “thing” exists, so there could be no minds to perceive it.
How do we know if we exist?
The only evidence you have that you exist as a self-aware being is your conscious experience of thinking about your existence. Beyond that you’re on your own. You cannot access anyone else’s conscious thoughts, so you will never know if they are self-aware.
