Discussion Overview

The discussion revolves around the existence of extraterrestrial life and the implications of mathematical models, such as the Drake equation, in proving or disproving the likelihood of intelligent civilizations beyond Earth. Participants explore various perspectives on the evidence for alien life, the motivations of potential extraterrestrial civilizations, and the limitations of current scientific understanding.

Discussion Character

  • Exploratory
  • Debate/contested
  • Mathematical reasoning
  • Conceptual clarification

Main Points Raised

  • Some participants argue that the vastness of the universe suggests a high probability of extraterrestrial life, citing mathematical reasoning and the potential for many civilizations to have existed over billions of years.
  • Others challenge the assumption that intelligent civilizations would colonize other planets, questioning the motivations and limitations of extraterrestrial beings.
  • Concerns are raised about the lack of direct evidence for alien encounters on Earth, suggesting that if advanced civilizations existed, they should be apparent by now.
  • Some participants express skepticism about the Drake equation, arguing that it can yield any result based on the assumptions made, leading to the conclusion that we might be alone in the galaxy.
  • There is a discussion about the implications of recent astronomical discoveries, such as the identification of numerous galaxies in previously unobserved regions of space, which some participants believe supports the likelihood of life elsewhere.
  • Participants note that while the laws of physics currently suggest limitations on interstellar travel and communication, these laws may not be complete, leaving open the possibility of future advancements.
  • One viewpoint suggests that if advanced civilizations were to detect Earth, they might choose to observe rather than interact, depending on the stage of human evolution.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence of extraterrestrial life or the validity of the mathematical models used to argue for or against it. Multiple competing views remain, with some participants expressing optimism about the existence of aliens and others remaining skeptical.

Contextual Notes

Limitations in the discussion include assumptions about the motivations and behaviors of extraterrestrial civilizations, the reliance on the Drake equation's parameters, and the unresolved nature of current scientific understanding regarding the universe's vastness and the potential for life.

Who May Find This Useful

This discussion may be of interest to those exploring astrobiology, the philosophy of science, and the implications of mathematical models in understanding the universe and the potential for extraterrestrial life.

I would rather discuss the potential that aliens are amongst us in this thread. Any sightings are only a small part of the overall bigger picture.

Norval,

You're the one who said you saw a ufo. If you won't explain, then I can only assume that you are just making this up.

regards

What, pray tell, is there to explain? Go read the net for all the sighting stories you want. This thread and my interest lay along the discovery of aliens and if indeed they are here just what is the reason? Start a thread about sightings if you want, I would be more than happy to ignore it as I do most threads. As I stated, I am satisfied that there is enough evidence to convince me that aliens are here. So get on with it or get over it. :wink:

I thought this forum was Scepticism and debunking? So I'm trying to debunk and/or learn about what you have posted.

You can't tell what it looked like or it's movements, etc?

After reading a few reports on UFO’s (The Cometa in another thread) It seems the phenomenon of ET here on Earth is such that they’re strategy or intentions is to slowly acclimatize us to they’re presence.

The idea that we’re alone in the Universe is very much a part of our understanding throughout history. IMO it’s a product from the religious view that Earth was created from God, or humans are separated from other species. Another factor is that we’ve only recently discovered the true scale of the Universe, and thus in knowing such things conclude that Life here on Earth is not a just a freak event.

So with the possibility that many habitable planets exist, and our current obsession to find life on Mars, other planets and radio signals from ET, in the view of many its simply a matter of time.

On the other hand ET could quite possibly be here already, and as before in the case that our species simply isn’t evolved enough to have any intellectual capabilities, there is no need to make contact. Perhaps we are on the edge of finding life in the Universe and ET just happens to be here simultaneously making its presence known in incremental steps.

Then again too, that a god may have created humans with more capabilities of intelligence than were given the other created beings out there in the universe? Maybe that is why ET would be so interested in humans? They may be far in advance of us with their technologies, but that does NOT make them more intelligent.
 
  • #37
Technology I think has a lot to do with knowledge, and the removal of incoherent concepts.
New discoveries challenge incorrect belief systems and eventually get accepted, so our understanding of the Universe is a clearer one. I wasn’t implying that we’re an unintelligent species, but that our knowledge is incomplete and always evolving.

That said, for a civilization wanting to know if life exists elsewhere, it needs to develop the means to find it. Without a doubt some are convinced life is abundant, and in the scenario that ET/s finds us first, (which I think is highly probable) what is the method of interaction? For one it could be observation.

hmm...that's a good one

if this theory is right then it will be true for those who said they saw UFO's in the sky! NV would we have expected that for all the time that we had spent to research other planets for these extra terrestrials, they r juz neighbours who lived on the same planet as us!

these would make more sense as to why we see UFO's flying around our area, like they would also see planes flying around pass their area too!

Grrrr. Just be glad the others answered this one already. This is one of my biggest pet peve misconceptions that people have about science. To reiterate simply: its wrong.

ET?
According to Carl Sagan, there are no less than 400 habitable Earth like possibilities in the cosmos as he believed it to be. You are more than welcome to argue this with Dr. Sagan if you wish but I'd rather not go visit him quite yet.
Isn't it completely possible that ET could be living among us at this very time in another, as yet to be discovered, dimension?
We normally see reflected light, what if ET does not reflect light that we are capable of seeing either with the naked eye or with instruments that we now have?
When I visited the UFO museum in Roswell the curator told me of a man who visited the museum that did not believe in ET because no one had ever seen ET. To this the curator ask the man if he believed in God, "yes" was his answer. The curator went on to ask, "have you ever seen God?" End of discussion.

At one point I was an alien.. but I guess that doesn't count :wink:

Personally, and based on the evidence - the fact that we are here and since the universe is so big, with billions and billions of possibilities for life elsewhere - I think the universe is almost certainly full of life; and probably with many forms of intelligent life in some sense. I'm not as confident that there are many creatures a lot like us.

As for other dimensions and the like, yes, some scientists like Michio Kaku believe that another universe may exist "just a millimeter above ours" [whatever that means]. However, this is not to say that invisible aliens from that universe walk among us. Simply put, we have no reason to believe what you suggest - there is no recognized evidence to support the idea. I could just as well claim that gravity is really due to undetectable, invisible tricksters from the netherworld. We can't prove that it's not true, but there is surely no reason to believe it.
