Article:300 MILLION possible earth like planets in the Milky way galaxy alone

Just imagine that number, its an ENORMOUS number of planets for life to possibly spawn on. Then when you factor in all the probable moons in those systems that like Europa or Titan, might harbor environments for life, and there is possibly a stunning amount of extraterrestrial life in our galaxy. here is a link to the article.

But THEN factor in THIS; the latest studies point to a population of approximately two TRILLION galaxies in our universe. So, if the lions share of those galaxies have even a fraction of the Earthlike planets our galaxy has, there could literally be BILLIONS of advanced civilizations out there.

Just some food for thought.

I hope so, I'm in the market for a new planet to inhabit. This is one has gone in the sheeter.

But honestly, I can't see how there isn't life somewhere else outside our neck of the woods. I think it's an awesome thing about which to think.

NASA can find 300 million earth like planets throughout the galaxy and yet the majority of our ocean bed has never been explored.

Apparently is easyer to make something to go to space and look really far rather than something that can survive water preasure and explore the ocean floor on its own.

Again, where they at? If even a tiny fraction of them managed to survive, there would not only be evidence of them, but depending on how advanced they are, they would be obvious with massive constructions potentially encompassing entire galaxies. And yet... not a peep. Not a single laser beam.

Yeah, I know the possible "solutions" to the Fermi Paradox. But when when you start talking about billions of civilizations, that makes the Fermi Paradox even more problematic. Not only are you talking about hypothetical civilizations, you're also talking about hypothetical reasons we don't see them. How many hypotheticals can you stack? Especially when hypothetical is essentially the same thing as "non-existent."

Just some food for thought.

You are assuming we are intelligent enough to recognize the technological signature of a civilization possibly billions of years more advanced than us. I am not sure that's true. I agree it stands to reason we would see something, but we have only been looking just short of a century, and the universe is very large and very old. Just because we haven't seen it yet doesn't mean it isn't out there. As a matter of fact, I think that FRB's are pretty intriguing. No solid explanation for them yet.

Correct. It doesn't mean anything. Just like the billions of potential habitable planets out there. The only way we'll know if there is an advanced civilization out there is to find it. Or find billions of them.

Or catch them walking around late at night in our grocery stores.

And once you reach a certain level of technology what then is the point? Think about it. Long before Dyson spheres or interstellar faster than light ships, all civilisations should reach a point where they could effectively map themselves in to code, achieve immortality and exist in Ai controlled worlds forever more or less. We don’t see alien races because at a certain point they turn inwards instead of outwards. Explains a lot. Look at our own technology now. Where are we heading most quickly? It isn’t towards light speed.

That's one possible argument. But how to prove it? And will they all do that? Out of a billion advanced civilizations, will they all do the same thing? If there is even a handful that manage to keep reaching out with their insane amounts of power to map or conquer the entire universe, we would probably see them. But we don't.

All of those worlds, all we need is one star gate.

The problem is it's all speculation we only have one planet that we know of that actually supports life. Until we find others its nothing but speculation. Something incredibly rare could have happened here that simply never happened anywhere else in the galaxy. Let's say odds were a trillion to one that means we beat the odds but would likely be the only ones.

If we start confirming other planets then we would be able to at least get an idea. So far seems like the earth is a very unique place so many factors were needed to create us. From having a moon to stabilize the earth's orbit to be the exact distance needed from the sun. The sun allowing sufficient time for life to evolve. Being far enough out in the galaxy to void all the radiation at the center of the galaxy. Having a large gas giant to catch asteroids cering the inner planets. Having a high enough iron content in the core to produce an electromagnetic field.

We could keep going but the point is a lot of things had to happen to get life on this planet. very few other planets are able to repeat what happened here.

Perhaps no surprise really,
The thing is the public conservatism of, say NASA, and what they actually think, or already know/knew anyway, as against non-scientists, who already may have been of the same opinion anyway...instinctively.

a reply to: dragonridr

Exactly. I have no doubt that life exists elsewhere in the universe and possibly within our galaxy, but until we find it, it's just speculation. It's entirely possible, although hard to imagine, that life here was just a fluke and we're unique.

a reply to: AdmireTheDistance

...that life here was just a fluke and we're unique.

Could be we're super special, though the odds would be pretty steep.

Cracking open the ol' speculation, what if most "life" in the universe isn't physical but non-corporeal? Boltzmann Brains, spirits, gods, night-bumpers, etc.

Perhaps life on Earth was not natural life but artificial robotic devices? Maybe some wispy intelligence experimented with physical servitors for some exotic reason, made us (and bacteria, plants, etc) and then left us to fend and evolve for ourselves, not really caring about the clunky physical nature of things? Or perhaps we're an ongoing experiment.

A scenario like left behind matter, or as an isolated experiment, might explain aspects of the big silence.

Ask any psychic, shaman or dimeth-etc smoker if the universe is empty.

Very good point, but to be fair stargazers are not deep sea explorers, well they are in a way but there sea is above our heads.
Also you would be very surprised as just how well the world's ocean's if not in there entirety and not at there deepest point's were explored during the cold war, there were even claims in at least one book of ruin's being found something like four or five thousand feet under water in the south Atlantic, an apparently man made staircase leading up from a sandy beach along the cliff at the now entirely drowned edge of the continental shelf and another on a sunken mountain range that is partially covered over in basalt flows but also looked man made, these were anecdotal tales at best and likely only third hand without evidence but supposedly the Soviets found these and the US found other's but it was not for the public - or the other side to know what and where they had been exploring or why.

Still we do have better and far higher resolution maps' - despite all the smudging and blurring out - of the moon than we do of the ocean bottom.

It really is only a matter of time though because despite the ecology already being severely endangered corporations are now starting to strip mine the bottom of the ocean's, and they won't tell you if there are ruin's down there even if they find them because they will just destroy them to get at whatever minerals there may be under them.

...there could literally be BILLIONS of advanced civilizations out there.

But there aren't.

If there were, we'd know about them. Not because we're so smart/advanced, but rather because they would have made themselves known by broadcasting their scientific advancements all over the universe for billions of years.

For every civilization like ours there would be billions of civilizations FAR more advanced than ours, and there would be billions of civilizations less advanced than ours. Billions, literally. But there aren't.

In fact, as civilizations go, we humans would probably fit in the lower 1/3rd of the spectrum. This translates into 2/3rds of the intelligent civilizations being far more advanced than ours, yet we haven't heard from any of them. Why? Because they aren't there.

Humans are selfish. We believe that we are so important that there must be others like us in the universe. Intelligent creatures. All humans do is destroy things, everything. Humans exploit everything, consume it, covet it and destroy it. That's what we do. We look to the stars to find other places like ours so we can consume, covet and destroy those too.

In the scheme of the universe humans are insignificant. We are irrelevant. To think we are so important that there must be others like us is arrogant beyond comprehension. We are just a blip on an infinitely long timeline, in an infinitely large space, with an infinite number of other probabilities and permutations.

Maybe there are tell-tale signs, but we’re just ignoring or misinterpreting them.

Look at this recent example of a detection of a rogue planet.

A rogue planet is a planet without a star – it just floats freely through space. We cannot directly observe it since it is too dark and too small.

But if it passes in front of a distant light source such as a star, it can act as an amplifying lens for the light of that star – the so-called gravitational microlensing effect.
The mass of the rogue planet distorts the space-time fabric around it, and the light of a distant star passing through this distorted space-time fabric is bend towards Earth a little, just like a lens would do, resulting in an amplification of the apparent brightness of that star.

So, the only thing we observe is a brightness variation caused by a localized space-time distortion which we assume is caused by a rogue planet.

What if that space-time distortion we measure is caused by a spaceship using space-time distortion as its means of propulsion, like the Alcubierre drive? Can we distinguish a planet from such a hypothetical spaceship?

In fact we can, since an Alcubierre drive distorts space-time in two opposite ways. At one end of the starship a distortion is applied comparable to the space-time distortion by a mass of a rogue planet. At the other end of the spaceship an opposite space-time distortion is applied. This opposite distortion acts like a negative lens, dimming the brightness of the star as seen from Earth:



So, for a spaceship with an Alcubierre drive we would expect an amplification of the starlight combined with a dimming of the starlight, while a planet would only show an amplification of the starlight.

What did they measure during this shortest timescale microlensing event?
The measurement points of brightness against time are in this graph:



The measurements do show a dimming effect next to the brightness peak.
In fact, the article states:

the best-fitting solutions had large negative blending flux

Which means the best fitting solutions to the curve included a dimming effect.
But these solutions were rejected because, according to the writers,:

such solutions are unphysical

In other words: The assumption that the observed curve is caused by a planet is so strong that data that contradict this assumption are simply rejected...

Another example is the detection of small asteroids in the vicinity of Earth. Sometimes these asteroids are observed for a while and then get lost because they do not follow their calculated trajectory. I wonder what is done with this data, but I guess it's just ignored.

One good posibility is every existing alien civilisation comletely obliderated their planet's recources trying to advance an ended up dying off bacause traveling outside a solar system is impossible. And each civilisation lasted what, 10k years? And even if they send something in space it could have been mllions of years.

Another great possibility is flat earthers were right lol.

I fact do we really know anything about the universe at all? What if life can start only now in our galaxy due to reasons and simply everyne else is in same advancement race as we are?

a reply to: ZeroFurrbone

Traveling distances of light years is not possible for beings constructed of matter or mass. Only if technology existed to disassemble those things and reassemble them again at a different location, from matter and mass available at the far end of the journey, would that type of travel be possible.

a reply to: openminded2011

and with an estimated 2 TRILLION galaxies in the known universe, the possibilities are endless in my opinion! Life is everywhere out there!
