Why aliens haven’t visited Earth yet

For 400 plus billion years there was an equilibrium as it relates to life in general.

First the asteroid and now us ..we humans are on a collision course to destroy our planet.

In the short span of a couple thousand years humanity has endangered the process in which life succeeds.

So, yes, in the end we will have disrupted the successful course of evolution.

There is no equilibrium of life in general. No such thing at all. There are constant changes that favor or disfavor one life form or another. Even if human beings do or do not exist, it does not mean other life forms can or cannot exist. We are part and parcel of evolution.
 
All true IMHO, but we would not even be here but for 7 mile wide fluke asteroid travailing at 45,000 mph, An impact equivalent to a billion nuclear bombs.

A few mammals survived in there burrows, that's it. Minus the asteroid the dinosaurs would have continued to evolve and mammals would have stayed small under the giants feet.

It begs the question, what is the thrust of evolution. And your right IMO, humanity has become a plague not compatible with the balance nature.

The thrust of biological evolution appears to be about living organisms adapting to a changing environment. Humans just happened to use more of the brain's problem solving skills.

Our advanced brain does give us many advantages in adapting to a changing environment. It's drawback is that we are also more capable of creating an environment that can lead to our own destruction.

And that's not what life wants, the complete and utter ruination of the planet.

Take us out of the equation and the Earth would heal IMO ..an equilibrium with life would be established once again.

A sixth mass extinction is underway right now, and it's not a asteroid this time, its us.

Half of Earth's species could go extinct by 2050 unless humanity addresses climate change and human sprawl.

Life is not something that wants or doesn't want. If we go extinct, life will go on without us in some form until the sun burns out. That's life.

All living things must remain in balance, or equilibrium, it's known as homeostasis.

Ecosystems can be viewed in the same manner.

However, the balance of nature, as a theory, has been largely discredited by modern scientists working in ecology.

It has been superseded by the catastrophe and chaos theory. I don't buy it.

The dinosaurs ruled for 150 million years, but for freak accident they'd still be here and order and balance would still prevail IMO.

If by chaos some scientist are referring to modern humans and they're destructive impact on life, I will give them that.

The various species in an environment do not need homeostasis with all other species to stay alive. Homeostasis applies to each individual living organism, and has nothing to do with the mythical balance of nature. Nature is not balanced at all, as evidenced by the ebb and flow of the population of various species.

Your wrong, ecosystems are a product of evolution and are balanced for the most part. They are what guide adaptations, one of the principles of evolution.

For a 150 million years dinosaurs lived in a relatively well built environment.

What changes a balanced ecosystem is most often some sort of natural catastrophe or a runaway species like humans.

No, ecosystems are not balanced. They may achieve some level of stability for a while, but they are never balanced.
 
The capacity of an ecosystem to regain its fundamental structure, processes, and functioning despite stresses, disturbances, etc., speaks to the age of dinosaurs ..its durability over millions of years.
 
It sounds like, from this article, that the universe is predisposed towards evolving life, just not merging it on planetary scales.


According to a new hypothesis posed by Dr Wong and Dr Bartlett: “We propose a new resolution to the Fermi paradox: civilizations either collapse from burnout or redirect themselves to prioritizing homeostasis, a state where cosmic expansion is no longer a goal, making them difficult to detect remotely.

“Either outcome — homeostatic awakening or civilization collapse — would be consistent with the observed absence of (galactic-wide) civilizations.”

The pair argue that the general principles of life are universal and that although the emergence and evolution of life on other planets remains speculative, it may be inevitable.

The Fermi Pardox asserts the odds of single cellular life evolving (let alone multi) are so astronomically impossible that there is no chance there was ever life before Earth, and nor will there be after Earth. Our planet is a one and done thing - and us as a sentient species is also a one and done thing. We are alone and will never happen again - how grateful we should be !

In an infinite universe, nothing is impossible. That there is life on earth proves that life can exist. And life here has existed for a long time. Maybe life started here first. Maybe it started somewhere else after. And maybe meteors didn't hit the reset button in those other places like it did here.
 
Already disproven. There are known particles that travel faster than light.
You're talking about particle entanglement, or light pushed through cesium vapor. Neither is actually FTL travel because neither information nor anything with mass can travel FTL. There are no practicle applications.
-----------------------------------------------------

A common misconception about entanglement is that the particles are communicating with each other faster than the speed of light, which would go against Einstein's special theory of relativity. Experiments have shown that this is not true, nor can quantum physics be used to send faster-than-light communications. Though scientists still debate how the seemingly bizarre phenomenon of entanglement arises, they know it is a real principle that passes test after test. In fact, while Einstein famously described entanglement as "spooky action at a distance," today's quantum scientists say there is nothing spooky about it.

"It may be tempting to think that the particles are somehow communicating with each other across these great distances, but that is not the case," says Thomas Vidick, a professor of computing and mathematical sciences at Caltech. "There can be correlation without communication," and the particles "can be thought of as one object."


I don't claim to understand this stuff — I certainly don't have the math for it — but all the scientists know are the results of their experiments. The how and why are still in question.

If life, from simple singular cellular to complex organisms, can exist here on Earth in a variety of different environmental conditions, it is probable that life can exist elsewhere under similar conditions. Given the sheer size and age of the universe, is is quite probable that exolife exists somewhere.

This is true. However, logically speaking, we cannot say that life definitely exists elsewhere. The possibility that the earth is unique remains. If we do find life elsewhere we may than extrapolate that life may exist in many places.

When you consider the size of the Universe, and the fact there are billions of sun-stars and planets that have existed for billions of years longer than Earth, we should have made contact with one by this point - even if by accident. The fact we haven't leads me to believe we are alone.

No, we cannot. Neither can we say exolife does not exist elsewhere.

Given that life exists in many different places and environments on Earth, we can simply scale it up and say exolife probably exists in many places in the universe too. But not with absolute certainty-yet.

We agree, just looking at it from different direections.

What do you base that on? Considering the sheer distance between stars, finding exolife, nevermind actually contacting it, is a daunting task and limited by our current technology.
The fact we haven't leads me to believe we are alone.
Numerical probability leads me to think we are not alone.
 
Common sense leads me to believe life exist elsewhere in the Universe.

Might exist on one of Jupiter's or Saturn's moons for that matter.

Where I'm hesitant, as to life elsewhere, is with highly intelligent life like ourselves.

Life in general is way to busy figuring out how to consume its neighbor.

Brawn trumps brains IMO, dinosaurs are the perfect example as to the trajectory of life and evolution.

The Milky Way galaxy is 13.6 billion years old.
The oldest planet in the galaxy is 12.7 billion years old.
Our planet is 4.5 billion years old.
Human self awareness came about 40k year ago.
There are planets in our own galaxy that have been around 7 billion LONGER than Earth.
That's more than enough time for a sentient species like ours to not only have evolved, but have created the technology needed to have traveled the entire galaxy and back a few times over.
Yet, there is no evidence of their existence.
We are it, bro.

Pure conjecture. For all you know, there might have been an intelligent species which bombed themselves back the the proverbial stone age. Or maybe there were intelligent species that went extinct when their host star went nova., ect.. We can speculate all day. We can't even peer too deeply in our own galaxy, nevermind galaxies that are millions or billions of light years away.
Yet, there is no evidence of their existence.
Not yet anyway. But that's why we're searching.
We are it, bro.
Mere assumption. You cannot possibly know that with certainty.
