I take it you mean "is our Sun still the original one". NO.
We know, (or clever folk do), that a Star of the size of our sun can only manufacture elements up to the mass of iron. And our Sun cannot manufacture Carbon!
Nucleosysthesis is the study of the energy/temperatures and time required for creating the elements from existing material. We know that the creation of Carbon for example can only take place in the explosion of a supernova.
Even the Big Bang did not last long enough at the needed temperatures for three Helium atoms to simultaneously collide to form a Carbon atom.
So our Sun is at least a 2nd generation star, and maybe a 3rd generation one!.
So you have much star material in your being.
All the energy that is now in the Universe was there since the time the Universe started - that is, since the Big Bang.
God was the one who made all and everything we see now. So everything we have including the entire universe was created by god.
God has always been, is, and will be. He has been around since before the universe was created at the least as stated in Genesis. There may be controversy about the religious aspect.
AnswerDeism is the belief that a God created the universe, but now demonstrates no apparent interest in it. Polydeism is a polytheistic form of Deism encompassing the belief that the universe was the collective creation of multiple Gods, each of whom created part of the universe and then ceased to interact with the universe.
True, since the speed of light is finite.
Al Khwarizmi is said to be the founder of Algebra, since he first used it.that why we use it now
The universe have been expanding since the big bang. After the first 200 seconds after the creation of the universe, the universe was the size of galaxy. Now how much the universe size is nobody can measure It is also said that a lot of matter and antimatter have been destroyed since then. In the first few moments of the universes creation, particles called quarks were formed. They soon fused to create the first atoms called hydrogen and helium. Larger atoms such as beryllium, oxygen and carbon were formed by the nuclear reactions inside stars. Even bigger atoms were formed due to the shock waves inside the stars such as tungsten or osmium. But all this took a lot of time to happen.
Children First Now was created in 1999.
"Where else did matter come from? If matter has no beginning and always existed, then matter must be god", this is a sentence you sometimes here religious people say in the defence of their belief. But if god is matter, it is bind by laws of nature, like all matter is. But laws of nature don't allow such thing as god. He would have to exist in some place of the Universe, since there is no place outside of the Universe. And how could he have created the Universe from inside it, just when there was nothing inside Universe, since it was a singularity, infinitely small space. A god couldn't have been outside the universe either, since there is no such place as outside the Universe, the Universe is all there is. And furthermore there was not time before the Big Bang (in which the Universe began), since time itself started at it. So there's no place or time in which a god could have existed before the universe was born. God didn't create the universe, all the matter the Universe is made of existed already at the singularity. It was compressed so tiny and dense taht eventually it exploded and formed the Universe. The matter was always there, and quite possibly there have been other Universes before this one, and they all ended up with a Big Crunch (which is an opposite of Big Bang), in which all the matter of the Universe compressed into a singularity, only to explode again into another Universe. We can never prove that theory, since time in which we can make observations started at the Big Bang 13,7 billion years ago and we cannot see before that. If someone believes the Universe is created by god, then they must ask themselves where did the god came from? Where is god now? How he was born? How he supposedly created the Universe? There's no explanation for any of those questions. There is absolutely no proof of god.
In the immediate aftermath of the "Big Bang" there was rapid inflation of the universe. That slowed and the universe is now believed to be still, slowly, expanding.
Right now
Lemaître, based on Hubble's observations, was the first to propose the idea of an expanding universe, leading to the formulation of what is now known as the Big Bang theory. He suggested that the universe began from a "primeval atom," which exploded and has been expanding ever since. This concept challenged the then-prevailing static model of the universe and laid the groundwork for modern cosmology. Lemaître's insights significantly contributed to our understanding of the origins and evolution of the cosmos.
