Could space colonization become the main ideology of humanity?

When we completely destroy our planet’s environment then and only then space conization would become our “main ideology.”

Sadly, however, even space colonization leads to the same question – will we destroy the next planet just like this one?

Is, or will, our Sun also become a variable star? If so, what kind?

Not a variable star with fluctuating brightness, but our sun is getting brighter gradually over time. As the fuel in the sun is spent the sun gets 10% brighter and 10% hotter every billion years. So we estimate in a couple billion or so years the oceans will dry up and all life on Earth will cease. Earth will become much like Venus is now. Eventually the sun will turn into a red giant and expand to swallow Mercury, Venus and probably Earth.

When will a rogue planet collide with Earth?

Worry about the future of life itself on the only planet ever found to have life.

When will a rogue planet collide with Earth? Probably never again, although smaller objects like comets might hit us. However the future for Earth and life on Earth doesn’t look good either way.

For a planet to collide with another is like a bullet hitting a bullet. Space is big compared to a tiny planet, and the chance that a rogue planet might actually collide here is a long shot, even though we believe it may have already happened once.

It’s pretty unlikely to happen again because that was back in the day when the solar system was still forming and more volatile.

But what is happening is that the sun is running out of fuel. Every billion years or so it gets about 10% hotter as a result. We estimate that in 1.1 billion years it will be too hot to sustain life on Earth. The oceans will evaporate, greenhouse gasses will take over and Earth will become like Venus: too hot and raining sulfuric acid. All this happens way before the sun becomes a red giant and destroys Mercury, Venus and probably Earth.

So you don’t have to worry about that rogue planet hitting us. You have to worry about the future of life itself on the only planet ever found to have life.

Am I a pessimist or a realist?

Relics of the Past Destroyed? Is it Islamic Extremists Again?

Back when the Taliban Government under Sudam Hussein was destroying relics and statues of Buddha in Afghanistan that were thousands of years old, historians were horrified. Could you imagine, for example, blowing up the pyramids of Egypt? The Taliban’s actions were reminiscent of the Nazi’s burning books, or of the Spanish burning all of the Mayan civilization books and with it their history.

Although the war between the North and the South was largely about slavery – owning people – it is still part of our history. It may not be the brightest point of our history, much, I suppose, like the Taliban saw their country’s roots in Buddhism and Hinduism (Afghanistan is a word coming from India’s Sanskrit language). They destroyed statues, figures, relics, historical monuments and every remnant of the past that they could get their hands on. Should we do the same, or should we see the bigger historical perspective?

Is it okay to have statues of important figures in the Confederate States of America? They went to war against the United States much like the thirteen colonies declared independence against the King of Britain and wrote the Declaration of Independence. The outcome of the two wars was different, but both were states fighting for independence.

Had the colonies lost their war and America stayed part of the British Empire, would we now be destroying the Declaration of Independence and all evidence of the revolutionary war? Probably not. It would be history nonetheless. Similarly, should we now destroy all evidence there was a war – our deadliest war – now that there is no more a Confederate States of America?

These symbols – the Confederate heroes statues and flag – are seen not just as reminders of our unfortunate past of slavery but in today’s climate as a line drawn by white racists against the rest of us.

Admittedly, the issues are boiling over.

Once again racism rears its ugly head. We see the revival of the KKK and an alt-right president who comes just after the first African American president. The country could not be more divided – except perhaps in civil war.

Historically, we’re in a time of extreme pendulum swinging from left (Clinton) to right (George W.)  to left (Obama) to alt-right (Trump). The swinging is getting wider and wider and different views seem irreconcilable.

Despite the troubled times of the present, would the destruction or removal of these statues be met with blessings from historians four hundred years in the future, or will they see it in the same light as destruction of the Mayans, blowing up of Buddha statues or burning of books?

People will do what people do and this article will not change history in any significant way, however it’s one liberal’s opinion.

Can it be reasonably expected that Earth will survive, regressing to its original state, surviving the human race?

For the first half of Earth’s existence there was hardly any breathable oxygen. There was no life. In the end, Earth will return to a state where there is no life.

So, yes, Earth will out-survive humans, and yes, it may and will return to a state where no living thing can survive on it.

Sooner or later, maybe a billion years from now, the sun will become a red giant. All life on Earth will have ended by then.

How long will the human race survive on earth?

Most likely up to a couple of hundred years from now we could see humans die out. Ideally it would be until the sun started to go weird on us and dry up the oceans, roughly a billion years to go from now. However, it is possible that climate change created by humans will render the planet unlivable much sooner. Give it 150 years then we’ll see.
