Researchers speculate that, in a model theory, time travel is possible – the theory is set out in the following link:-

http://news.bbc.co.uk/1/hi/sci/tech/4097258.stm

The possibilities would be endless – so why not take the opportunity to stretch your imagination for a few minutes.

There are no right or wrong answers, everyone comes up with different answers, and it can give a revealing insight into a persons’ personality and interests

These are the rules:

• You can choose just three times / places to visit
• Your visits must be back in time (not forward)
• You can only observe from a safe distance (a fly on the wall view) – you cannot interact or change events
• You cannot use the visits to achieve personal wealth – only to gain knowledge / experience of historical events / characters
• Visits must be to earth (and it’s moon) only and you cannot go back to any point prior to the existence of the fully formed planet Earth
• Your time machine can be programmed to visit a specified event / person – even if you don’t have an exact date

After much deliberation, these are my top three choices:

1 – The Demise of the Dinosaurs

My time machine would take me to a time of apocalypse.

What killed off such a successful, varied species who had dominated the planet for 160 million years?

Here are just a few of the great many theories regarding the demise of the dinosaurs

• The collision of a large meteor with the earth
• Extreme volcanic / super volcano activity
• A reduction in volcanic activity, which led to dramatic climate change (planetary cooling) and significantly reduced oxygen levels
• Bizarre and disadvantageous genetic mutations
• A magnetic pole flip
• An increase in earth’s gravity and reduced oxygen levels

It is the last theory which is of particular interest, and one which many people may not have even heard of.

The pre-historic age was a time of giants, giant plant-life, insects and creatures.

The following sketch shows the astounding scale of a Sauroposeidon dinosaur.

A valid question to ask is – why then, do we not have modern land living species on the scale of those found on pre-historic Earth?

Evolutionary theory may suggest that there was no necessity or advantage to growth, human species supremacy was achieved by development of the cerebral cortex, brains over brawn, however, this cannot be said for other species.

There may be a simple explanation for this enigma – gravity limits size – theories suggest that gravity today would make it impossible for large creatures such as the Sauroposeidon to move or even breath.

I have included two links below to set out illustrate this point:-

The burning question therefore is how and when did earth’s gravity increase, and could this be a valid explanation for the demise of the dinosaurs?

Gravity is a universal force that remains an enigma to scientists.

On a large (planetary) scale, mathematical models have been created which seem to be accurately supported by what we can see in our surrounding universe.

However, on a quantum scale, gravity behaves very differently and cannot currently be adequately explained. A valid gravitational theory has become the holy grail of quantum physicists.

With such a lack of understanding of the fundamental nature of gravity, it would be difficult to ascertain the cause or reason for an increase in earth’s gravity.

There is however a theory which would explain increased gravity within the realms of our current model – ie gravity is directly linked to mass – if the earth had grown, considerably, the mass increases and therefore gravity would increase proportionally.

Is it feasible that at some point in history, the earth expanded and grew, increasing gravity?

The following link is to a theory regarding expanding earth.

If earth grew, then all other planets within the solar system would have had to have grown proportionally to remain in constant orbital positions to the sun – but where could the matter come from to achieve growth? – the accumulation of matter would be difficult to explain in anything other than a living organism – is our planet a living organism? Do we know enough about the universe to reject this idea out of hand?

I would note that there is an abundance of information both in support and opposition to this theory should you chose to research this subject further.

I recently came across a couple of articles which could also potentially support an expanding earth theory

Article 1 – New Scientist reports upon how gravity is mysteriously disappearing from our universe

http://www.newscientist.com/article/mg18524872.100-the-mystery-of-disappearing-gravity.html

High gravitational forces keep planets small, could a gradual reduction of gravity throughout the universe allow planets / stars to somehow expand?

Article 2 – Huge unknown matter has been detected beyond our universe, pulling all matter towards it at a rate of 2 million miles per hour. It is therefore a possibility that our gravity is being pulled out of our universe.

This study is monumental and the findings may eventually overthrow the big bang theory – ie our universe is not moving away from a single point of explosion, but being pulled apart by another/ or numerous other universes – “multiverses”.

It should also be noted that the exact structure, formation and nature of the earths core is also a scientific enigma – despite all our scientific advancements, we have huge gaps in our fundamental understanding of the earth.

In the 1990’s scientists discovered that the earth core was a molten crystal structure, about the size of our moon.

In February 2008, a theory was presented that earth’s core is in fact a crystalline cube – as far as I can ascertain, crystalline structures can grow under the right conditions.

See the link below, presenting the latest research regarding the earth core’s composition.

To determine the cause or causes of one of the most dramatic events in planetary history has got to be a worthy use of one of the three time trips.

2 – The Construction of the City of Petra

Petra (located in Jordan) has been classed as one of the “new” wonders of the world.

You may recognise it from the set of the film “Indiana Jones and the Last Crusade”.

The identity of the builders and the exact date of construction remains a mystery, a matter of debate amongst historians and archaeologists.

For more information on Petra visit

http://www.trifter.com/Asia-&-Pacific/Jordan/Fascinating-Places-The-Ancient-City-of-Petra.338733

My main interest in Petra is derived from a theory that the city was built by a race of ancient giants! (Giants have also been linked to the construction of Ancient Egypt and Stonehenge)

The Old Testament Genesis 6 states “There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown”

http://www.gnosis.org/library/dss/dss_book_of_giants.htm

The bible, however interesting and thought provoking, provides no evidence of fact – but the interesting point is that archaeological remains of gigantic skeletal remains have been located in various locations around the globe – many have apparently mysteriously gone missing when sent for analysis, and inevitably and sadly, some are hoaxes.

The above foot picture illustrates one of many human footprints (found next to Dinosaur tracks) in the Paluxy river, Texas. Compression studies conclude that this is a woman’s footprint, a woman estimated to be approximately 10 feet tall and weighing over 1000 lbs

I will put a couple of links for you to look at which support the giant hypothesis:-

A time trip to Petra under construction, to take a look at the craftsmen, has therefore got to be in my top three trips.

3 – Roswell (New Mexico)

Ok, I’ll admit it, I had a misspent youth watching Star Trek!

But consider the facts, there is a huge universe out there with more galaxies than there are grains of sand on the earth, many have numerous orbiting planets and the hunt is o for one similar to Earth (take a look at http://www.galaxyzoo.org/ a fantastic chance to glimpse awe-inspiring photographs of nearby galaxies taken by the Hubble telescope).

The picture below is gas pillars “pillars of creation” in the eagle nebula, taken by the Hubble telescope.

Earths water, which spawned and sustains all life on the planet, is theorised to have arrived from deep space as a result of an epic meteorite storm sometime during the early development of the planet.

Studies have shown that meteorites and comets contain vast amounts of fresh water – so take a minute to consider the possible origin of the alien liquid in your next cup of tea!

Check out the link:

http://news.nationalgeographic.com/news/2006/02/0202_060202_comet_ice_2.html

It always surprises me that it is such a leap of logic for some people to consider that life may exist, in some form, elsewhere in the universe.

Having said this, plausibility does not equal fact and I am very aware that an open mind, leaves us vulnerable for anyone with a motive, to try to deceive and mislead us on a grand scale.

The entire arena of extra-terrestrial / UFO information is awash with misinformation, potential hoaxes and conspiracy theories, it is a very difficult area to research.

However, whilst wading through a mountain of information, I came across a theory which caught my eye.

“Project bluebeam” a conspiracy theory that proposes a governmental plot to dupe the general public into a new (controlled) spiritual belief system based upon faked alien teachings – a scheme so shockingly all encompassing, co-ordinated and high tech that it is worthy of a read.

The technology required to carry this plan off convincingly is developed and available, truth or fiction, who knows? However an awareness of what could be done is certainly interesting (especially for any fellow sci-fi fans) I have included a link below.

http://educate-yourself.org/cn/projectbluebeam25jul05.shtml

There is so much hype around Roswell, July 7th 1947, to observe the actual events first hand might give some insight into the question – who is fooling who?

Your Turn

As you can tell from my three time travel choices, I have an interest in world mysteries.

I asked a few friends to give me their choices, here are some examples:-

• Trips to witness great historical battles,
• Trips to visit great historical leaders
• To attend great gigs (Hendrix, Elvis, the Beatles)
• To witness religious events
• To witness sporting events

Whatever floats your boat, it is a good way to idle away a few minutes – so get your grey cells working and let me know where, in history you would chose to visit and why.
