How many years ago did the big explosion occur?
What explosion And if you are talking about the Big bang it happened about 13.7 billion years ago
How many years does it take light to travel to us from the edges of the universe?
Light from the edges of the observable universe takes about 13.8 billion years to reach us. This time corresponds to the age of the universe itself since the Big Bang. However, due to the expansion of the universe, the actual distance to those edges is much greater than 13.8 billion light-years.
About many years ago do scientists think the universe first started to form?
Scientists estimate that the universe began forming around 13.8 billion years ago during an event known as the Big Bang. This marks the beginning of the expansion of space and the creation of all matter and energy in the universe.
How many years ago did the precambian era begin?
The Precambrian era began approximately 4.6 billion years ago, at the formation of the Earth, and lasted for about 4 billion years.
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 many years ago did the universe formed?
'''The''' Big Bang, which was the creation of this universe, was probably about 14 billion yearsago.
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.
How many years equal a billion years?
A billion years equals a billion years. 1,000,000,000 years
How many years are in 1 billion?
1 billion years = 365.25 billion days (rounded)
How many million years are in a billion years?
There are 1000 sets of 1 million years in a billion years.
How many million years are in 13.8 billion years?
13.8 billion years equates to 13,800 million years.
How many years are in 8 billion minutes?
8 billion minutes = 15,210.61 years
How many seconds are in 13.7 billion years?
There are 432339120000000000 seconds in 13.7 billion years.
How many years is 300 billion seconds?
300 billion seconds is about 9,506.4 years.
How many light years is the diameter of the known universe?
The OBSERVABLE Universe has a diameter of about 93 billion light-years. "Observable" means that the light of anything beyond that hasn't had time to reach us, since the time of the Big Bang.
Approximately how long ago is the big bang thought to have occurred?
The question is fun, and it would be fun to calculate. But the answer would have no meaning at all, because the question suggests a level of precision that the answer can't possibly have. We would have to be able to accurately identify the time of the event to at least the nearest second, which is impossible. Also, any estimate of the number of seconds would not be reported to that degree of accuracy, so converting back to the units you started with would be called for. Not only can we get no closer than billions of years, we are not even certain beyond doubt that it happened. The question is a little like asking 'How many cubic centimeters of water are there on Earth?' We cannot know the answer to the level of accuracy that 'cubic centimeter' suggests. I think about 473,040,000,000,000,000 seconds. Multiply 15 billion years by 365, then 24, then 60, then 60 again and you'll have it.
