Did the Milky Way explode fourteen billion years ago?
No. The milky way did not exist at all, fourteen billion years ago. According to the Big Bang theory, the first galaxies started forming at least a million years after the universe had started to expand.
How long after the big bang did it take for stars to form?
the theory states that atoms formed during the big bang (like right as the big bang happened) Protons and neutrons were allowed to form about one second after the Big Bang. Electrons joined to nuclei to form permanent atomic bonds about 377,000 years later.
How long after the big bang do scientist think it takes before the first star is born?
Larger stars (larger than our own sun) usually have relatively short lives, around 100 million years. That's because they tend to have more hydrogen to burn, expand much faster, and go through their supply in less time. As opposed our sun with a predicted life span of about 9 billion years.
Were Most of the elements heavier than helium made during the first few minutes after the big bang?
According to the big bang hypothesis, hydrogen was the only element created after the big bang. Within the first few minutes, the temperature was hot enough for fusion to occur, enabling helium, lithium and a few other elements to be created. After about 3 minutes, the Universe cooled sufficiently, for this process to halt. It was not until about 500,000 million years later, when the first stars went supernova, that heavier elements were seeded into the Universe.
Did all iron on earth originate from the big bang?
No. The only elements made within a few million years (actually a few seconds) after the Big Bang were hydrogen, helium, and trace amounts of lithium. Iron was not created until stars began nucleosynthesis.

When and where was the first sunlight ever to shine?
Around the corona of the first star ever formed, about 400 million years after the Big Bang.
What event occurred first the formation of the sun or galaxies?
The first stars appeared about 400 million years after the big bang. Galaxies would have formed around 2 billion years later.Our Sun was formed about 9.2 billion years after the big bang.
How long did the universe stay dark after the bang?
Better known as the "Dark Ages", the Universe was opaque (Foggy). Estimates vary but it is believed to have lasted between 150 -> 800 million years after the Big Bang. However, with the first stars developing around 400 million years after the Big Bang, the "Dark Ages" would have ended shortly after the first stars. See related link for a timeline of the Big Bang.
How long after the big bang do scientists think it takes before the first star is born?
our universe is currently 13.7 billion years old and about 155 million years after the big bang , first star is born and by this way stelliferous era was started .
When did the first stars and blacks holes form?
The first population III stars formed about 400 million years after the big bang. The first black holes would have formed when these stars exploded, about a few millions years later.See related link for a timeline of the big bang.
How long ago was the first star formed?
The very early history of the universe after the Big Bang is mostly guesswork; we cannot be certain as to the precise schedule of what happened when. But most scientists believe that stars didn't begin to form for at least a few hundred million years.
What is the earliest time in the universe that you can directly observe?
a few hundred thousand years after the Big Bang
How long have Neutron stars been in the universe?
The first neutron stars likely formed some time in the first 600 million years after the Big Bang when large stars of the first or second generation died.
When was first element created?
About 377,000 years after the Big Bang
How many days did it take the big bang to make the earth?
The Big Bang did not make Earth. Earth formed roughly 9 billion years after the Big Bang by a process called accretion. This process took roughly 20-30 million years.
