When protostars became so dense that nuclear fusion began in their cores and light would occur. how do scientists theorize that heavier elements than hydrogen and helium were formed? When lighter atoms within the stars fuse together, becoming heavier atoms..
Keeping this in consideration, what is the theorized life cycle of a star?
Life Cycle of a Star. Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.
Subsequently, question is, how was the universe created? 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.
Hereof, how do scientist theorize the planets were formed?
Orpheus theory which says that a planet-sized body collided with Earth and sent some of its material into orbit, forming the moon.
How were the first elements formed?
Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. During the formation of the universe in the so-called big bang, only the lightest elements were formed: hydrogen, helium, lithium, and beryllium.

Why do stars die?
Stars die because they exhaust their nuclear fuel. The events at the end of a star's life depend on its mass. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon.What happens in the life of a star?
A star is born once it becomes hot enough for fusion reactions to take place at its core. Stars spend most of their lives as main sequence stars fusing hydrogen to helium in their centres. The Sun is halfway through its life as a main sequence star and will swell up to form a red giant star in around 4.5 billion years.How are stars born?
Stars are born when large gas clouds collapse under gravity. They form hot cores that gather more and more gas and dust until a protostar is formed. If only a small amount of gas is around, then only a small star will form; if a large amount of gas is present, then a massive star will form.Why do stars twinkle?
The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.What stage of life is our sun in?
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium.What is a star made of?
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.Where are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.What causes a supernova?
What causes a supernova? One type of supernova is caused by the “last hurrah” of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers.When did water first appear on Earth?
4.6 billion years ago
Where did Earth's gold come from?
During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals -- such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.How old is the universe?
13.772 billion years
Where did the water on Earth come from?
Both comets and asteroids can contain ice. And if, by colliding with Earth, they added the amount of material some scientists suspect, such bodies could easily have delivered oceans' worth of water.Does the earth create new water?
Planet Earth makes its own water from scratch deep in the mantle. Our planet may be blue from the inside out. Earth's huge store of water might have originated via chemical reactions in the mantle, rather than arriving from space through collisions with ice-rich comets.When did the universe form?
13.7 billion years ago
How are suns formed?
The sun formed more than 4.5 billion years ago, when a cloud of dust and gas called a nebula collapsed under its own gravity. As it did, the cloud spun and flattened into a disk, with our sun forming at its center. The disk's outskirts later accreted into our solar system, including Earth and the other planets.How is solar system formed?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.Where does our solar system end?
Based on where the planets end, you could say it's Neptune and the Kuiper Belt. If you measure by edge of the Sun's magnetic fields, the end is the heliosphere. If you judge by the stopping point of Sun's gravitational influence, the solar system would end at the Oort Cloud.Who is the creator of universe?
Vishnu is the primary creator.How many universes are there?
The multiverse. If we define "universe" as "all there is" or "all that exists," then obviously, by definition, there can be only one universe. But if we define "universe" as "all we can ever see" (no matter how large our telescopes) or "space-time regions that expand together," then many universes may indeed exist.
