Building Blocks of Life Found on Mars

how could it have been a BIG BANG when in space sound can't travel because surely we would have heard the bang by now :cautious:

That only implies that there was once some aspects of an environment suitable for life, as we know it, to function, not evidence of life.

there is no science that can back the claim of anything beyond x thousands of years let alone x millions or x billions

Just because the soil "looks old" does not make it so, quite easy to "fake age" most everything, and when this rocks or whatever they "test" never leave their hands, hmmmmmmmmmmmmmmm.

that is nasa as well as numerous government agencies, elitsts etc "selling kool aid" should you NOT agree with their "pseudo science" that means untold trillions of dollars of revenue annually, globally, they will bury this information because they so do not want the gravy train to come to a grinding halt, nor admit that in fact for generations they have been outright lying, cause distension in the ranks ^.^

Our measurements are only as accurate as the PEOPLE using them, PEOPLE are anything but perfect therefore the data they use in most everything should not be taken as "accurate" especially regarding the "age of the universe, the rocks, the soil samples collected". We are very fallible because we as human beings are anything but perfect, trying to make what we do appear "without fault"

We know the science behind combustion, the methods needed to fly and such things, there is a great deal of what we more or less KNOW to be 100% repeatable so therefore a very high % of accuracy and probability, for everything else, is worthless conjecture.

Interesting nonetheless, but, the moment claims fly around that "oh this is BILLIONS of years old" means they pile one pile of lack of credible evidence upon another.

in other words, hearsay, which is not nor should be admissible in anything besides, I dont know, FOX news LOL

I just find it funny as oh hell that they woull go out of their way to "convince" people so they continue to get paid $$$$$$$$$$$$$$$$$ but when it comes to admitting where they could or likely are wrong in their estimations, mum's the word as the saying goes.

Maybe I missed something, but are you in so many words saying the field of GEOLOGY is a big conspiratorial cover up that is perpetuated for the money?
 
So something statistically impossible like life evolving from nothing happens here and you want me to believe coincidentally it happened on the next planet over also? The chances of that happening are worse than me and my neighbor winning the Powerball every week during our lifetimes by independently picking the same numbers.
 
This thread is an embarrassment for a tech forum. Kyle, delete and try again!

For the most part they have pretty much confirmed there was life on Mars at some time in the past.. billions of years ago. The same as other planets and exoplanets.. it seems the whole galaxy was filled with life billions of years ago, and then something happened (Big Bang maybe) that killed off life on pretty much all planets including Earth. But, Earth "found a way" to come back and created humans (potentially with the help of God, if you believe in that) and here we are thousands of years later trying to put the puzzle pieces together. Unfortunately, I think we will end up killing ourselves on Earth before we put all the puzzle pieces back together and solve anything.

Would you care to cite your source?

I ask because my wife is currently working on the 2020 Mars rover plan, has been working with the data coming from Mars for some years now, and she specifically is involved with looking for signs of life. According to her they have found none but her argument is that everywhere we've looked we've found some kind of life.

What she is looking for is essentially the excretions of extremophiles. As far as I know that is the end of the line for current data on extraterrestrial life on Mars. Now to be fair there are people out there who are more on line with this topic. Many Mars scientists eschew Earth time and sleep on Mars time so they can be up to date on the latest data coming in. We're not going that far. But maybe someone who is has found some evidence!?

This doesn't mean there was life on Mars. It just means that conditions on Mars have been at least somewhat suitable for life in the past.

Eh, we have no basis for how unlikely life is. We know life spawned on earth less than a billion years after it formed, but complex microorganisms didn't show up until about 600 million years ago. This means, at the cosmic timescale, we are either SUPER special, or that basic single-cell life isn't all that rare to form. I think finding organic space slime is infinitely more likely than finding other sapient lifeforms.

I would go so far as to say that finding other sapient lifeforms is unlikely at best, impossible at worst based on the statistics.
 
With all the planets out there, I'm reasonably certain other sapient life exists. Whether or not we'll ever be able to travel far enough to meet encounter that life before it goes extinct or we do is another matter entirely.

If they want to find life, they will have to go under ground.
That's where Martian life fled when the oceans dried up 100's of thousands of years ago.

Anything left on the surface and been ground to dust by the wind storms a long time ago.

It's not just being able to travel far enough.
The unanswered question is how long would an advanced civilization survive?

Considering the age of the universe, there could have been dozens of advanced races that traveled to our planet, but non arrived during the short time humans have been around.

Source? To my knowledge they have not confirmed anything. The only thing they have found is evidence that there might have been life, not that there was life. Also, I have never heard of a theory involving what you are suggesting that there was life, it was wiped out and then somehow Earth came back.

You don't need a source. The posters credibility pretty much disappeared with the pondering if the big bang killed most of the life :D

Oceans do not automatically mean life. There are rivers of liquid methane on Saturns moons, surely a river must mean fish, too?

They're trying, this is a big step.

The Viking microbiology experiments found evidence for metabolism and nitrogen fixation in the soil, but until now they have not been able to detect carbon-based molecules in the soil. They weren't sure if it was being masked by other compounds or if the surface really was sterile.

Life seems much more likely now that we have carbon along with a seasonal methane cycle.

While there was likely an ocean we currently have no evidence, fossil or otherwise, of past life on Mars. There was a debate about bacteria-like structures in Mars meteorites, but while interesting it was not conclusive and there are reasons to think they could have been formed without life.


Mars has a very thick crust (100+ km) and it's interior cooled more rapidly than the Earth's did, resulting in some major geological differences. The geological features you can see are the result of early volcanism and then deformation as the interior cooled rather than plate techtonics. This may ultimately be why the planet ended up cold and dead in the first place.

It isn't pseudo science. There are plenty of things to measure. For instance:
Nuclear fusion is understood well enough to get a good estimate of a stars age based on its mass and heat output.
We can only see so far away because the speed of light is finite. There is 13.77 billion years there.
Not to mention the cosmic background radiation from the big bang and extrapolating the drift and acceleration of galaxies.
The matter in the universe is not new and appears to all be flung out of a singularity.

I know they are trying, it is just hard to get excited when you get the same rehashed story every few years that they have found the potential. It is sort of like crying wolf, albeit not completely the same, it end up having a similar effect. I will be excited when they finally find life (or the remnants of life) somewhere outside Earth.

Not even sure what to say here about that. There is nothing about Mars surface to suggest life. Geography does not give much indication of life. As others have mentioned, there are oceans, rivers, etc on other planets. That does not mean there is life there.

Theoretically, if a species can last long enough to achieve faster than light travel, it could secure its future almost indefinitely so long as additional habitable worlds are within reach or sufficient resources exist to construct habitats in space.

Agreeable. There could have been plenty of intelligent species that have come and gone all at different stages of development. It is also conceivable that such advanced species could also be able to avoid being seen by our looking glasses we use to look outside out planet. Or just by sheer odds alone, like trying to hit bit a bee with a laser 100 miles away without being blocked by anything in between.

While I would love to believe if we go out far enough that space looks like babylon 5, but it could very easily be void of intelligent life all together, at least during our blink of an existance so far. Hell I would be excited to see non intelligent life.

When we get out there and find humans, things will get awkward.

It's difficult to calculate what the real odds are of finding intelligent life out there. I have to wonder if the amount of life out there would make our Galaxy more like Star Wars (lots of very different sapient species), Star Trek (lots of humanoid or near human species), or like Mass Effect where there are very few advanced, space fairing civilizations at any given time. One thing people fail to understand is that Earth is essentially a back water planet near'ish to the edge of the Galaxy. We are in the middle of nowhere.
 
Ill say this, if light speed is an unbreakable absolute rule, we are fucked. If intelligent life is out and about travelling FTL, they would avoid us as we would be at most, what are ants to us.

More than likely none of those. More like we may be the only current sentient life in the universe, but there may have been life at some time on other planets, even potentially sentient life. But the likelihood of multiple sentient races at the same point in time in the universe is not that likely and certainly not on the level of SW, ST, or ME.

I don't think that's true. If there are other species that possess some type of FTL technology then they probably look at us the way we would primitive tribes or ancient civilizations. We know from first contact with primitive tribes just how much of an impact our presence can have on them. Likewise, super intelligent species would probably avoid us for fear that we would panic, riot, and worse yet, attack them. While their ships likely have little to nothing to fear from us, coming down and talking to us in person is a bad idea. We have a subset of the population that's not mentally advanced enough to handle alien visitors without becoming hostile.

In other words, they are smart enough to avoid us for now.

Also even just like you said, they might not even know about us. Such an advanced species probably wouldn't have a whole lot of interest in a species still digging up dead dinos and plants to burn for fuel

Who knows, maybe even some of our technology might have something unique that they never thought of. Ill trade my old teddy ruxpin for a FTL engine please.

Exactly what brings you to this conclusion that we might be the only sentient life out there? Why would you think that multiple sentient species would be improbable? How did you calculate this? There are planets that formed far earlier than ours in this galaxy alone. The sheer volume of stars and planets out there makes it almost statistically impossible that we are the only sentient life out there even if we are exceedingly rare. Even if only one planet per galaxy is capable of supporting any type of sapient life, there is still a lot of potential for life in the universe.

I would agree that at present, it seems unlikely that there is any life that's technologically similar to us within close proximity to Earth. In fact, it seems unlikely that there is any similarly developed species within a few hundred light years of us. However, that's only based on what we've observed near us. When there is a potential for another planet, or dwarf planets within our solar system, its obvious we still have a long way to go before we can be sure that we haven't missed something.

From scientists at NASA whose job it is to find signs of life out there. If you believe that the universe was created by the Big Bang or something similar, and you calculate the growth of the Universe out from the center, it stands to reason that there are certain times in the Universe's life that life is the most probable, and that period slowly spreads out. So that things further out may not have gone through that transition period yet, while areas closer to the center may have had ones that came and gone. Given the age of the Universe and how it spreads and the tremendous amount of things that have to go right and continue to go right for life to exist and mature, the likelihood of 2 sentient species being alive at the same time is pretty small. Heck the chance of life itself is incredibly small. So when you put the chances of life and then match it up with the expansion periods of the Universe, it becomes increasingly less likely that 2 sentient species will actually exist at the same time. SW, ST, and ME all have many sentient species currently alive and trading with one another. That is incredibly unlikely. Even if there were other sentient species currently alive in the universe, the likelihood of them being close enough even with FTL to trade is highly doubtful.
