The big bang hypothesis suggests that 20 billion years ago?
Cosmologists now conclude that the Big Bang (BB) occurred 13.7 billion years ago. Since it is meaningless to speak of something happening "before" the BB -- there was no time or space to have a "before" -- BB Cosmology makes no statement about what happened that long ago.

What would be happened to the earth after one hundred billion years?
one hundred billion isn't a small number. In 100,000,000,000 there won't be an Earth. According to physicists, the universe is expected to end in 15 billion years. It might expand into a big empty void or crunch up into super dense material, maybe the size of an atom. That too if there even is an earth in 15 billion years. In 5 billion years, our Sun will die. It will expand and expand, swallowing up the Earth. It might not make it to five billion years, with asteroid impacts obliterating it (remember, 5 billion years is A LOT of time). In conclusion, in 5000 million years, the Earth will be swallowed up in a fiery mass. Hope this answers your question
