Does anybody think that there's life on mars?

Question

I mean, it's just creepy that there's only life here on earth. There's gotta be another source, at least in another galaxy. We can't possibly be alone.

Answer 1

Mars... the cool think is that likely in our lifetimes we'll be able to answer that question. I won't be surprised if they do find some microbial life there. I'll be surprised if they don't find some evidence that there once was some sort of life on mars. Intelligent life... another question, but life, i'm looking foward to scientists finding it there.

But I would be MY LIFE that there is life, in some form, in OUR galaxy, somewhere.

Answer 2

Yes, i believe that there are alien organisms, meaning that there are bacteria and other microscopic organisms that may have once existed or still exist. There are all the elements on mars needed to sustain life. I dont believe that there are aliens though.

Answer 3

Life as we know of it only exists on Earth.

Answer 4

Yes, there is.

We have sent roving machines to the surface of mars. It is unlikely that they arrived without a single microbe on board. At least some of the lifeforms on Mars came from Earth.

Answer 5

There is no life on Mars. There might have been one day, but not anymore.

Mathematically it is impossible life only to be here on Earth.

But if we were alone, I can't see why it would be creepy.

Leaving religion well out of it, let's calculate the chances aliens do exist. There are roughly 400 billion (400 000 000 000) stars in the Milky Way alone. The estimated number of all the galaxies in the universe, calculated by the pictures from the Hubble Space Telescope and multiplied times left out space coverage, is somewhere around a hundred billion (100 000 000 000). Multiplying the estimates, we come up with 4 × 10²² or forty sextillion stars estimated in the universe.

Here is where it gets tricky. No one has yet been able to calculate how many stars actually have planets orbiting them (how many stars are in solar systems). If each of the stars had the same number of planets on average as our sun, there are 3 200 000 000 000 planets in our galaxy alone, multiplied by the number of galaxies makes the total estimated number of planets in the universe 3.2 × 10²³ (3 200 000 000 000 000 000 000 000 - three septillion, two hundred  sextillion).

The number is gastronomical. That's what astronomy is all about. So now we have a buhmillion planets. How many of them actually have the basic fundamental attributes to sustain life as we know it?

Any ratio I come up with leaves me a huge number of possible planets.

I will post the calculation on my website soon.

Now we know there HAS to be other life out there.

Answer 6

scientist have all the proof that life on mars could have indeed existed but if it did it was bacteria

Answer 7

In order for life to exist on Mars, its dynamo would have to be reactivated. This would have to be done either thru mechanical, chemical or magnetohydrodynamic means. A dynamo creates the magnetic field which deflects gamma, x-ray and cosmic radiation. A magnetic field also protects any water from being photo-dissociated by solar uv, a process which strips hydrogen from water molecules while the solar wind blows them off into space. Mars once had flowing rivers, but lost all of its water and atmosphere due to photo-dissociation by solar uv radiation. There are 166 moons in our solar system that need dynamos built into them to make them habitable.

Mechanical vibrations can provide the friction required to produce plate tectonic-like motion in the crust. If enough heat is generated thru this friction, magma may form and fall towards the core, reactivating the defunct dynamo. I'd bring a bunch of washing machines, jackhammers, Turbines, power tools, motorcycles and blenders up there to shake things up.

Alternatively, we can bore a shaft and pour in molten liquid iron/nickel/cobalt, add some polonium, radium, etc. and throw in some water and sodium (Na) for good measure. This ensures an eternal inferno is roaring deep down in the mantle to stoke a fire in the core. If all else fails, we'd have to install a Superconducting Ring (between 4 to 14 Tesla in strength, depending on how much iron/nickel is resident in the core to begin with) to artificially generate a magnetic field/shield. The Ring runs on a persistent current which is estimated to last 10^23 years. It'd have to be sealed in a liquid helium tank much like an MRI machine.
