During the Big Bang, all of the space, time, matter, and energy in the Universe was created. This giant explosion hurled matter in all directions and caused space itself to expand. As the Universe cooled, the material in it combined to form galaxies, stars, and planets.
How was space created from nothing?
Virtually all astronomers now believe that the universe sprang forth in what is known as the “Big Bang” explosion, from a state of extraordinary compression and phenomenally high temperature in which forces such as gravity and electromagnetism were unified in a single, all-encompassing force.
How did universe begin?
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.
How 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.
How old is the Earth?
Today, we know from radiometric dating that Earth is about 4.5 billion years old. Had naturalists in the 1700s and 1800s known Earth’s true age, early ideas about evolution might have been taken more seriously.
How did time begin?
According to the general theory of relativity, space, or the universe, emerged in the Big Bang some 13.7 billion years ago. … “In the theory of relativity, the concept of time begins with the Big Bang the same way as parallels of latitude begin at the North Pole.
Who created the world?
According to Christian belief, God created the universe. There are two stories of how God created it which are found at the beginning of the book of Genesis in the Bible. Some Christians regard Genesis 1 and Genesis 2 as two totally separate stories that have a similar meaning.
Is time finite or infinite?
As a universe, a vast collection of animate and inanimate objects, time is infinite. Even if there was a beginning, and there might be a big bang end, it won’t really be an end. The energy left behind will become something else; the end will be a beginning.
How long will the universe exist?
The universe will cease to exist around the same time our sun is slated to die, according to new predictions based on the multiverse theory. Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of years more.
What is at the center of a black hole?
The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down.
Will the sun explode?
After the sun has burned through most of the hydrogen in its core, it will transition to its next phase as a red giant. At this point roughly 5 billion years in the future, the sun will stop generating heat via nuclear fusion, and its core will become unstable and contract, according to NASA.
How long will the Earth last?
By that point, all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
Who was the first person on Earth?
Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as “a human” and in a collective sense as “mankind”.
What keeps Earth from falling?
The Sun’s gravitational force is like the tetherball rope, in that it constantly pulls Earth toward it. Earth, however, like the tetherball, is traveling forward at a high rate of speed, which balances the gravitational effect. This means that the planet neither flies out into space nor falls into the Sun.
Who created time?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
Can time travel possible?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
Does the time exist?
So yes, time exists. … As to how it works, we certainly learned a lot in the past century or so, with the discovery of relativity theory in particular and the realization that time and space are inseparable aspects of the same fundamental reality, the spacetime in which we live.
Who created the 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. Atheists counter that there is no reason to assume the universe was created.
What are the 7 things God created?
- in the beginning – God started creation.
- the first day – light was created.
- the second day – the sky was created.
- the third day – dry land, seas, plants and trees were created.
- the fourth day – the Sun, Moon and stars were created.
- the fifth day – creatures that live in the sea and creatures that fly were created.
How old was Adam when he was born?
Genesis 5:3 says “Adam was 130 years old when he fathered a son in his likeness, according to his image, and named him Seth.” Cain & Abel were old enough to work with crops and herds before Seth was born, so the longest possible time would be around 120 years.
Is time an illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.
Is the past infinity?
Since there’s no negative infinite number, there’s no infinitely past year or earliest year. Each year is separated from any other by a finite number of years (remember that there’s no first year).
Is time in Black Hole infinite?
No. It is proportional to the enfolding surface tension commonly called a singularity or quantum gravity. The smaller the singularity, the slower the rate of time. This affects the ability of the black hole to assimilate and increase value short of merging with other black holes.
What will happen in 100 trillion years?
And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs.
How long until universe ends?
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.
Will the universe become a black hole?
Unlikely. Recent developments that show our universe is expanding at an ever-increasing rate. The cause of the expansion, called dark energy, is not understood, but it appears that the universe is destined to undergo a slow and cold death.
What is inside a white hole?
In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. … White holes appear in the theory of eternal black holes.
Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
What is on the other side of a Blackhole?
The discovery of light from the other side of a black hole was predicted by Einstein’s theory of general relativity. … The research began with a slightly different aim of a more common light formed by a black hole: the corona which wraps around the outside of it, formed as material falls in.
Is the sun getting smaller?
That’s when the sun will become a red giant, which it will remain for about a billion years. Then, the hydrogen in that outer core will deplete, leaving an abundance of helium. … Once all the helium disappears, the forces of gravity will take over, and the sun will shrink into a white dwarf.
What will happen if Moon is destroyed?
Destroying the Moon would send debris to Earth, but it might not be life-exterminating. … If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
Is there life on the sun?
The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun’s light and energy.
What will cause human extinction?
Potential anthropogenic causes of human extinction include global thermonuclear war, deployment of a highly effective biological weapon, an ecological collapse, runaway artificial intelligence, runaway nanotechnology (such as a grey goo scenario), a scientific accident involving a micro black hole or vacuum …
Will the Earth run out of oxygen?
When will Earth run out of oxygen? … The extrapolated data from these simulations determined that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. That’s the good news. The bad news is that once that happens, the planet will become completely inhospitable for complex aerobic life.
What will happen if the Earth stops rotating?
At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
Was the first human a baby?
In the moment nobody would have known any specific baby was the first human. There was never a day when an ape-like Lucy the Australopithecus gave birth to a human baby and everybody was like, “Whoa! What the heck is up with THAT kid!?” (Translated from the original Australopithecine.)
How long was Earth created?
In a process known as runaway accretion, successively larger fragments of dust and debris clumped together to form planets. Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) and was largely completed within 10–20 million years.
How was the first human born?
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.
What would happen if the Earth stopped spinning for 42 seconds?
If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock.
Is Earth moving towards sun?
We are not getting closer to the sun, but scientists have shown that the distance between the sun and the Earth is changing. … The sun’s weaker gravity as it loses mass causes the Earth to slowly move away from it. The movement away from the sun is microscopic (about 15 cm each year).
What is gravity kid friendly?
Gravity is a force of attraction that pulls together all matter (anything you can physically touch). The more matter something has, the greater the force of its gravity. That means really big objects like planets and stars have a stronger gravitational pull.
