Does Fermi Paradox really hold up

A famous scientists Enrico Fermi had a thought, if there is life in the universe why haven’t they contacted us by now. A lot of people thought this meant of course that there was no life in the universe.
This was idea came about the same time we were just learning about DNA and how it passes information from one generation to another. This was before extremophiles were found on the bottom of the oceans, Later the Frank Drake came up with a formula to express what is needed for people to figure out whether or not there is life in the universe.
The Drake equation starts with stuff like what we have a fairly good idea of such as how many stars in the galaxy, this has increased because the average size of a star has decreased therefore given higher number of stars. The number of stars that are formed each year. To things we a less accurate idea of such as how many stars have planets and how many planets around each star. Then to things we have no real evidence for such as how many planets have life, how many of those have intelligent life and how many have survived, The Drake equation can have many different results because we have no real evidence either way on these terms. And there could be other factors that may have an effect on whether or not aliens have contacted us. Maybe they have no interest in contacting others or we have not gotten to a certain amount of development to warrant contact. Maybe the haven’t gotten to a level of development to contact us, not everyone experiences progress at the same rate. Some ancient civilizations could of been around during an ice age and decided just to move on. It could we are in a civilization desert and in another part of the galaxy there could be a lot more.
We are finding planets around a lot of stars around stars that thought would not find them. Some of them a lot closer to the star then we thought the would. What astronomers are looking for are planets in what is called the habitable zone which is an area where water can exists in gas, liquid and solid. But in our own solar system people are thinking there could be life under the ice of some of the giant moons around Saturn and Jupiter. Plus some the gas giants around other stars might have large moons themselves where life could exist. Plus there are planets that belong to no solar system that could have any icy crust and oceans underneath where life could exist, So until all the planets and moons in the universe is tested, I will always have life that there life in the universe.

The Ongoing Story of Trying to Find Life on Mars.

Filed under: Uncategorized — davidlpf @ 8:58 pm


Every since Giovanni Schaipelli found what he called channels and later mistranslated into canals on the surface of Mars people have been looking for life, intelligent or microscopic every since. Percival Lowell a wealthy businessman from Lowell, Massachusetts was so taking by this idea that he built an observatory in Arizona, later this observatory was used to find Pluto in the outer regions of the solar system. In the 70’s there was Viking that test the soil for evidence of life that turned up nothing. In 1984 the was a meteorite found in the Allen Hills it left Mars billions of years ago. It was tested in the 90’s for evidence for life on the inside of it and in 1998 was announced that there was there were fossils of bacteria inside of it but there has been doubt of it. In the 2000’s two rovers landed on Mars called Spirit and Opportunity land one the red planet and Opportunity is still in operation, These two found evidence of water, these were chemicals that could only exist or be formed in the presence of water such as “blueberries” which is a special kind of hematite a compound of iron found different locations. There was also the Phoenix lander that discovered chemicals called perchlorates that react with organic molecules and thought to have been evidence of life on the red planet. Satellites orbiting the planet have many geological features that might indicate there was or water on the planet.

Today it was announced that the Curiosity rover the newest rover on the planet, it has been there since 2012 found organic chemicals. These chemicals include molecules such as benzene and toluene and smaller molecules such as propane and butene. There were other organic molecules detected that had sulfur and chlorine but could be determined exactly what they were because the detector was not set up for such large molecules.

What does mean, well nothing for sure. There can be life on the planet now but we still need more evidence. Life need water and ther not much of it on the planet at the moment so it is more likely that there was life on Mars in the past when there was water. One thing that might indicate is the presence of methane in the atmosphere which is produce by living things. There could have been life in the past but again need more evidence. If life arose early in martian history it means that life does take long to start and if that is the case life might not rare in the solar system or in the universe as a whole. These a great pieces of evidence but we need more evidence before we know for sure if there is life out there.
