Table of galaxies

I wonder if all galaxies have a certain stable mass size that they can all be classified into.  If so galaxies could be classified by mass, similar to the periodic table.  Once classified the behaviour of the various types of galaxies could be investigated to make future predictions.  For example, some galaxy masses may be more likely to clump together into clusters.

Free air conditioning

Since the act of cooling something is achieved by removing energy from a system, it should be possible to create a self contained cooling device that uses the heat from the environment as the energy source to cool the environment.  This could save significant power used to cool our homes. 

Measure the speed and direction of the Earth

If the speed of light is constant as stated by Einstein, regardless of the frame of reference.  We should be able to measure the speed of light between two points in an x, y and z plane.  Any difference in speed detected between any of these planes should allow us to calculate the speed and direction of the Earths motion relative to the universe.

Parallel universe theory is wrong

The parallel universe theory states that parallel universes exist where everything that can happen will happen.  Since there can be infinite number of combinations of everything happening there would be an infinite number of universes with every possible scenario played out.

Here is why I think this is wrong.  The above theory would include a universe where infinite order would exist and a universe where infinite disorder would exist.  Both of which break the laws of thermodynamics.

How life transitioned to land

It is often shown in big Earth history that at some point in the ancient past life that lived in the ocean crawled out of the ocean to live on land.  I believe this notion of life simply crawling onto land, is wrong.  What benefit would life have coming out of the ocean if it was adapted for life in water.

My theory is that life in water transitioned to land by changes in the environment.  As water levels raised and lowered over millions of years (possibly due to ice ages) some shallow waters that held marine life would have dried up.  Often killing off any life that existed in that water.  This would have happened many thousands of times in different parts of the world.  Eventually a body of water would have dried up that contained life that had the right adaptations to survive outside of water.  This life would have continued to evolve various adaptations to made it better suited to life outside of water.

Some of these shallow waters that previously hosted marine life would contain a seabed created by layers of organic life.  This would be perfect soil that would allow for plant life previously underwater to now grow on land.  These plants would became a food source for life on land.

Habitable zone

As we search for the existence of life on other planets that are within the habitable zone.  Let's take a look at our own planet.  The earth is in the habitable zone and has been for a very long time.  But DNA evidence shows us all living things are related indicating that life took hold on this planet only once.  This just highlights the fact that a planet could be in the habitable zone and have all the nessary ingredients for life, yet even after billions of years it is extremely rare for life to start.  We are extremely fortunate that life took hold on this planet, we need to not take that for granted.

No life on Mars

As much as we really want to find something, I don't think we will find life on Mars.  Look at the Earth as an example, when there is life on a planet it's everywhere.  The soil on the ground is made up of billions of years of organic material as thick as mountains.  Life has spread everywhere and can be seen from space looking down.  If there was life on Mars, after billions of years there should be some obvious sines.  But there are no sines so we try to dig looking for clues.

I suggest we recognize there is no life there and start planning to put life there.  It's not enough to just put people there.  We need to put an ecosystem up there so life can sustain itself.  We should start looking for suitable species and start planning.
