How long is a billion seconds?
I found that 1,000 seconds ago was equal to almost 17 minutes.
It would take almost 12 days for a million seconds to elapse and 31.7 years for a billion seconds.
Therefore, a trillion seconds would amount to no less than 31,709.8 years..
Can a supernova destroy a planet?
According to the model, when stars at least 7 to 10 times the mass of our sun go supernova, the blast swallows any inner planets, those orbiting out to several times the distance between Earth and the sun. (See “Red Giant Sun May Not Destroy Earth.”)
Is the sun getting bigger?
Because the Sun continues to ‘burn’ hydrogen into helium in its core, the core slowly collapses and heats up, causing the outer layers of the Sun to grow larger. … It is a very gradual process, and in the last 4 billion years, the Sun has barely grown by perhaps 20 percent at most.
What year will the sun explode?
Don’t panic, though – that won’t happen for at least another five hundred million years. Eventually (in five or seven billion years time), the Sun’s life will come to an end. Our star will swell up, becoming something called a “Red Giant” star. It might even get so big that it swallows the Earth whole.
What will happen by 2030?
Projections. The world will need at least 50% more food, 45% more energy and 30% more water than it did in 2012, according to United Nations High Level Panel on Global Sustainability estimates. India will surpass China as the most populous country this year or earlier.
How long is a billion years?
109 yearsA billion years (109 years) is a unit of time on the petasecond scale, more precisely equal to 3.16×1016 seconds. It is sometimes abbreviated Gy, Ga (“giga-annum”), Byr and variants. The abbreviations Gya or bya are for “billion years ago”, i.e. billion years before present.

How long have humans existed?
about 200,000 yearsWhile our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago.
How old is the earth?
4.543 billion yearsEarth/AgeEarth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
How long will the Earth survive?
7.5 billion yearsIf any humans are still around, they might have the technology to move the Earth to safety. Otherwise, life on Earth has a maximum life expectancy of 7.5 billion years.
What will happen in 100 trillion years?
100 Trillion Years – The Universe Dies This is the point at which the universe would reach a maximum state of entropy. Any stars that remain will continue to slowly burn away until the last star is extinguished. Instead of fiery cradles, galaxies will become coffins filled with remnants of dead stars.
What will happen in 2040?
Health. We will all wear a huge range of sensors that will constantly monitor things such as blood pressure, blood sugar and blood oxygen level. Longevity will rise, with many living well beyond 100. Children born in 2040 will have a more or less indefinite life.
How long until our sun dies?
about 7 billion to 8 billion yearsAstronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. Humanity may be long gone by then, or perhaps we’ll have already colonized another planet.
What will happen to the Earth when the sun dies?
It’ll swell into a red giant, whose outer layers will engulf Mercury and Venus and likely reach the Earth. Life on Earth will end. If the sun were more massive – estimates vary, but at least several times more massive – it would explode as a supernova.
Is our sun white?
Around sunrise and sunset, when the sunlight travels through a lot more atmosphere than usual, sunlight on earth’s surface becomes even more red. But the sun itself is white. Sunlight spectrum in space as a function of wavelength.
Is our sun dying?
The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
Will the earth run out of air?
Before plants evolved on Earth, there wasn’t enough oxygen in the atmosphere to support animal life on land. We and the other land species are utterly dependent on them to be able to breathe. As long as we sustain Earth’s plant life in sufficient quantity, we won’t run out of oxygen.
What will happen in 2050?
Stabilization in the population will happen in the second half of the century. It is calculated there will be 601,000 centenarians (people at least a hundred years old – born before 1950) in the United States by 2050. … According to this study, 9.075 billion people will inhabit Earth in 2050, against 7 billion today.
