How long do you think humans will be around?

Nothing last forver, but in a potential infinite multiverse it might repeat endlesly. Would you say we are still human if we digitized ourself? Would we be still humans if we write our own DNA? We keep changing

Nephilim they are Giants according to Wikipedia. It is actually difficult the find a ancestor that was larger then we are. The brain takes a lot of energy and theirs little family that was as erect and tall as we are also our near infinite supply of food has made us abouth 10 cm larger wiki.
I'm sure the first genetic tweekings have already been done. Make some chinese or russian kid that produces a large amound of natural steroids and place them somewhere where they most likely get into a sports carrier.
Even if this isn't the main reason. Their are penlty of people reproducing that would have succom to illnesses long ago if not for modern medicine. Also theirs many things that we would correct at birth. Why not trow them out of the gene pool. With genetic inhansements. Few people would dissagree with removing genes that cause alzheimer or gain genes that give you superioir but still human level eyer sight.
THese times are extremly close by

Open enetrances to the open ed matrices line in A-1 plus A+2 = C - 0 or 0 0 or 0 o 0 continues until everything is spread space wants an even mass: without an even mass go home to a black hole or come home to a planet. Without applied atropy or entropy.

 

A-1 + A+2=3?

 

Yes, Counter: you and Asexperia and Forceman should get together. We should make a subforum just for you guys.

 

Don't have any idea.

 

I can try to give this a shot

Yep, definitely true we are about half-way through. However, as our star burns more and more hydrogen, it gets slightly brighter as time goes on. Think the estimate is about 10% brighter every billion years or so. In a billion years, once 10% brighter (gradual of course) it would be extremely hot on our planet, and we may more closely resemble Venus. However, we may evolve with our ever changing planet.

Going to certainly be rough once Helium starts to burn in the core. Obviously wouldn't happen suddenly, but once it starts we need to find a way off planet if we haven't already. So in terms in the original question, if 10% to the luminosity of our star isn't enough to make the planet uninhabitable (which, personally I think it would), then this will of course do the planet in. Any hope of our survival at this point would to be off planet. Going to Mars, however, wouldn't solve our issue. At this point, we would most assuredly need to be traveling to another star system if we haven't already.

Not most, all (except for that so tiny of a possibility that even a physicist will assume it is zero). There is so much space in space that basically no 2 stars will collide when we merge. In terms of our current lifespans, we would never even know it is happening once it begins. It is a few billion year ordeal or longer. What will happen, though, is during the gravitational play-date, some stars will be ejected from the galaxies. Luckily, our star will already be dead by then if it were one of the lucky few.

First what the star will do is puff up in a red giant, eventually shedding it outer hydrogen layers, and eventually the helium layers in a beautiful planetary nebula, leaving behind the white dwarf. Personally, I don't think Earth would be around to see this as I think we will fall into our star during its red giant stage.

To answer your question directly, I think Humans will be one earth sometime between the next 5,000 years, and the next 50,000,000.
I'm choosing 5,000 as a minimum due to an assumption of us killing ourselves in some way. I don't think we will kill ourselves by nuclear war, I don't think Yellowstone will put an end to us, and I don't think Global Warming will do us in (yes, I have hope that we will start doing better... changes have already started, small, but it must start small as a seed to grow into something great), but they are possibilities.
I'm choosing 50 million as the upper limit due to our star, gas giants (planets), and boredom. How star is gaining heat, our atmosphere is changing. This is the third (I think) atmosphere our planet has had. It will change again, and it could become toxic. As of now, our gas giants, quite astonishingly, never made the move toward our star. This is a decently rare occurrence (from my understanding). It really doesn't take much of a nudge to change an orbital path of any of our gas giants which could completely destroy everything. Asteroid, enough said. and boredom... If we survive 50 million years, we will have developed the ability to travel between stars. At heart, we are explorers (as all species at or past out level on the kardashev scale must be), and the thrill of going elsewhere I think will finally be enough to get everyone off planet.

Also... you did say Humans. There is a very real chance we turn ourselves (evolve) in mechanical beings in the near future (few hundred years). At that point, to answer your question, it must be defined what we consider to be human

According to the beach boys, for as long as the bad guys leave us alone (possibly by establishing ourselves as even greater bad guy?), we can successfully deceive our primary sexual partners, make lots of money, and also have the means to access a functioning automobile:

My buddies and me are getting real well known
Yeah, the bad guys know us and they leave us alone
I get around (get around round round I get around)

.....

I get around (get around round round I get around)
From town to town (get around round round I get around)
I'm a real cool head (get around round round I get around)
I'm makin' real good bread (get around round round I get around)

....

I get around (round, get around-round-round, ooh)
(Wah-wah-ooh)
(Wah-wah-ooh)
(Wah-wah-ooh)
We always take my car 'cause it's never been beat
And we've never missed yet with the girls we meet
None of the guys go steady 'cause it wouldn't be right
To leave their best girl home now on Saturday night

From town to town (get around round round I get around)

 

I think a 10% increase would turn our planet into something like Venus. Moving to Mars could be a solution since that would now be warmer but it still would not have much of a magnetic field and thus couldn't hang on to an atmosphere. It also has a very elliptical orbit and therefore its temperature swings are pretty extreme.

I think these are the kinds of things that may greatly limit life throughout the universe. It is widely assumed, just due to the immense nature of the universe, that most possibilities are out there including intelligent life. I somewhat agree with this as well but that may not be the case.

It may be that the time it takes for adaptable intelligent life (man vs whales) to evolve against a clock of its star changing its inhabitable zone may be a real limiter on intelligent life. The adaptable part may be the rare aspect as well. If every planet has smart sea life they still won't be communicating with us and we will never learn of them.

Not having a magnetic field may be the thing that dooms most life in not being able to hold on to an atmosphere. The universe may be full of low level life or non-adaptable life and spread apart so far that there might as well be no other life as far as it concerns us here on Earth.

 

Or the planet could have an alternative, such as twenty miles of ice or a completely subterranean bi0sphere.

 

I think it will be quite a challenge for humans (and any large mammal) to survive more than another thousand years. I sure as heck am glad I'm not going to be one of those that has to meet that challenge. We have failed our descendants. It's going to be ugly as all get out.

I'm don't know what will happen in the future. We might just get a break.

Or some folks will show up with a cookbook.

 

Funny, I always thought the present was a PDF.

 

I saw what you did there.

Are you seriously going to argue with a 700 year old turtle?

 

Thought the one with 4 elephants on its back holding up the flat Earth was older than 700 years

Stephen Hawking said that if humanity wants to survive in the future then we need to get off this planet and inhabit a new one.

I think that one of the biggest problem humanity faces now and will also face in the future is that there is not enough natural resources here on Earth to meet all of our needs and desires.

Also global warming, climate change, asteroid impacts, a giant solar storm, a destructive gamma ray burst and other dangers coming from outer space could destroy all life on Earth (as we know it) so in the future if humanity really wants to survive then we must leave the Earth and find a new planet.
