A great mass changes the flow of time in its surrounding. Clocks go slower near a great mass.
A great mass changes the space in its surrounding. Distances are enlarged near a great mass.
The combined effect on time and space near great masses is called the curvature of space-time.
A body moving straight trough the curvature of space-time near a great mass
moves like on a bent line through a gravity field.

It is not used up but only transformed to a new form.
First law of thermodynamics
The Drake Equation introduced in the early sixties by Frank Drake,
is a method to estimate the number (N) of extraterrestrial civilizations
in the Milky Way with the ability to send radio transmissions which we
might be able to receive.
R* = rate of formation of suitable stars
fp = fraction of the stars with planetary systems
ne = number of those Earth like planets with conditions for life (e.g. temperature)
fl = fraction of these planets where life actually develops
fi = fraction of these planets where intelligence develops
ft = fraction of these planets where technical knowledge develops
L = length of time in years such civilizations release detectable signals
Dr. Frank Drake is President of the SETI Institute.

Aluminium atoms (0.00000028 mm each).

Atom layer of Sodium chloride (common salt) molecules covering the edges of an aluminium crystal.
Visualize that we enlarge the length of 1 mm (=approx. 1/25 inch)
one million times, so it has the length of one kilometer,
then an atom would have the size of a 1/3 mm. Now the atom is already
visible as a point.

A 1965 book on science: .. a computer will not be able to play chess because for the first thirty draws there are ten in the thirtieth power positions. If a computer can check a position in a billionth of a second it will need more than 3.000.000.000 years to calculate the first 30 positions..

'Three dimensional mobility' - a flying car
'Changing the way people get around' - one person flying platform

Gastrobots - a machine with a sweet tooth
Telebuddy - internet controlled robot
I was in cyberspace and have heard computers sing
- reality is for people who can't handle science fiction -
Consequences of the second law of thermodynamics:
- Heat can't flow from a colder to a warmer body.
- Heat can't be transformed to power for 100%.
- In an isolated system disorder must increase with time.

and for the rest of us maybe quantum levitation.
