How do we know the universe is billions of years old?
We do not know the exact age of the universe, but we believe that it is around 13 billion years – give or take a few billion. Astronomers estimate the age of the universe in two ways: (a) by looking for the oldest stars; and (b) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang.
How long would it take to reach 93 billion light years?
How many years it takes light to travel x distance. It would take light 93 billion years to go 93 billion light years. But the universe will expand more during that time. The visible part of the universe is 93 ly in diameter.
How can it be that the edge of the visible universe is 46 billion light years away?
However, the distance to the edge of the observable universe is about 46 billion light years because the universe is expanding all of the time. … While that photon has been travelling through space, the universe has expanded. We have moved away from the point where the light was emitted, and it has moved away from us!
How long would it take to travel 4 light-years?
Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
Can the universe be older than 14 billion years?
The Universe might well be older than 14 billion years, and we should stop putting a limit on it every time something new is discovered. … It has over 10 billion light-years in length, and it is located well over 9 billion light-years away from us. The observable Universe is 93 billion light-years across.
