WE ARE NOT ALONE IN THE UNIVERSE
UPDATED WITH LATEST DATA ON DISCOVERED EXOPLANETS
Our sun is one of over 100 billion stars in the Milky Way galaxy and there are more than 100 billion galaxies in the universe which was formed about 4.5 billion years ago.
Life on Earth has existed for many hundreds of millions of years and in our humanoid form, for only the last 10,000.
It is the author’s belief that considering the vastness of…

VOLUNTEERS TO TRIAL CRYO-HIBERNATION!
I have talked in previous posts about the various medical and equipment requirements for a 20 year cryo-hibernation at 5 degrees Celsius. But how do you gain the confidence that the process works and that you will wake up and be mentally and physically fit to carry out your mission at another star?
Testing can be done on animals to give a high degree of confidence but the…

EQUIPMENT FOR CRYO-HIBERNATION
We need to consider the equipment requirements for an extended cryo-hibernation at say 5 degrees Celsius. We will need a very sophisticated cocoon in which our astronaut can be connected to the many life support systems described in earlier blogs.
One key issue is how to exercise the body during our 20 year hibernation. We often wake up after one nights’ sleep and stretch to…

TECHNOLOGY FOR CRYO-HIBERNATION
We need to consider the medical and equipment requirements for an extended cryo-hibernation at say 5 degrees Celsius. This week we will focus on medical issues.
The bodies’ metabolism must be slowed to a minimum ‘ticking over’ state whilst maintaining oxygen and blood flow to all vital organs and tissues albeit at a…

CAN MAN HIBERNATE FOR PROTRACTED SPACE TRAVEL?
CAN MAN HIBERNATE FOR PROTRACTED SPACE TRAVEL?
A journey to a star would mean a minimum of 20 years in the confinement of a spaceship – not impossible but a physical and mental strain for the crew – would they arrive in the right frame of mind to tackle the rigours of a new environment. Also they would be at least 20 years older, so experienced astronauts in their 30’s would already be ‘old’ on arrival. Maybe our crew would comprise of…

HOW CAN WE PROPEL A STARSHIP TOWARDS LIGHT SPEED? – 1
Let us imagine a journey to a star 10 light years away. We start from Mars orbit and outside the planet’s gravitational pull and use advanced rocket technology to reach Jupiter. This is a journey of 555 million kilometres [km] taking 7-8 months at 100,000 km per hour. [Approx. estimate of future capability]
We use the immense mass…

CAN MAN TRAVEL AT THE SPEED OF LIGHT? – 1
According to our laws of physics the answer is no. But the question for space travellers is how near the speed of light [c] we can get?
Light travels at 300,000 [approx] kilometres per second [186,000 miles per second]. When we look at our sun, not directly of course, we are seeing it as it was 8 minutes and 19 seconds ago. That…

WHEN CAN MANKIND REACH THE NEAREST STARS? – 1
There are a number of milestones and challenges for mankind if we are to contemplate travelling to our nearest stars, 5-20 light years away.
We must first establish a large moon-base towards mid/end of this century. This is feasible because we have discovered vast amounts of ice at the poles giving us water to drink, oxygen to…
