Either a very cool white dwarf or possibly a black dwarf. [See related questions]
The universe is actually about 15 billion years old. I'm not sure where you got the statistic that the Hubble Space Telescope can see 20 billion light years into space; I think you're off by a factor of three or so.
The Big Bang
94 years old
I have an albino African clawed frog that is 16 years old. I have one that turned 22 in March of 2009!
Nobody would live very long on Mercury.But I think what you're asking is: "How many times does Mercury revolve aroundthe sun in the same time that it takes the Earth to make 15 revolutions ?"Since Mercury's period of revolution is 87.97 Earth days, I get 62.3 Mercury yearsin 15 Earth years.
It will last about 15 billion years
most likely, the end of the sun would be because of its age. it only has about 4 billion years left. A star's lifetime is about 15-20 billion years.
About 15 billion years old
My universe is approximately 13-15 billion years old. How old is your universe?
approximately 15 billion years old, theoretically first shown at the big bang.
yes the earth is going to end in about 15 billion years the other answer is that depents on the sun
According to present knowledge and models of the Universe, the first galaxies could form when the Universe was less than 1 billion years old (it is now about 15 billion years old).
15 trillion 211 billion seconds equates to 482,018 years.
Rubidium 87 has a half life of 49 billion years so it would be 3 half lives. There should, therefore be 1/8 remaining. However, it is believed that the universe is less than 15 billion years old. So finding any object that is 147 billion years old is - to put it mildly - totally impossible!
Religious materials suggest to some that the universe is about 6 thousand years old. The 15 billion year estimate comes from the backward extrapolation of movement of the outward moving galaxies. It is theorized that this outward movement most have started about 15 billion years ago, if currently understood distances and velocities are worked backwards.
Yu Gwan-sun was born on March 15, 1904 and died on October 12, 1920. Yu Gwan-sun would have been 16 years old at the time of death or 111 years old today.
That would be the distance from one edge of the Known Universe to the other. As the Known Universe is believed to be approximately 15 billion years old, that would be 30 billion light years in diameter.
