Planets are considered to be capable of supporting life if they orbit their star within the goldilocks zone where liquid water can exist.
By my reckoning the Earth lies outside this zone with a black body temperature of 250°K where water can only exist in a solid form.
Would alien astronomers write it off ?

Colliding black holes emit a vast amount of energy in the form of gravitational waves for a few milliseconds ,What would be the effect of this on one or would other forms of radiation pose a greater threat

I recall seeing such a machine illustrated in in a pop culture scientific science magazine in the thirties has technology court up with science fiction yet.
Physics, Astronomy & Cosmology / What would be the implications of the Graviton having a non zero mass« on: 29/03/2016 23:55:55 »
If the Graviton has a non zero mass its range is no longer infinite but how much is its range limited if it has a mass close to the maximum established by the LIGO results.
We are told that virus's are not living entities but when I read papers on vaccine production reference is made to attenuated or killed virus's.
To kill something it must be alive or is it like Schrödinger's cat both

We are told its very bad for you, I hesitate to experiment!
Is it possible that the concept of time is different for intelligent aliens to that of ours ?, when we look for signs of alien radio communications should we look for a range of modulations that are well away from ours or are there physical restraints that would make them similar.

The remains of a group of people with abnormaly small heads were found and refered to as Hobbits could it of been caused by the zika virus

The normal minimum orbit time for the Earth is about 84 minutes so to orbit it in 40 would require the continuous expenditure of energy , how much kilowatts per Kg of pucks mass.
possibly Puck being an ethereal being he might have zero mass which would of course reduce the energy required !
I rather resent people claiming they haves "built a computer" when what they have done is purchase a commercially built mother board and plugged a few circuit boards into it and loaded commercially available software.
Any one who has built even a calculator from TTL to their own design knows this is a task of much greater magnitude than "building a computer".

I my dining room I use a Samsung 22" monitor both for TV and computer display.
recently I had a strange problem with the screen colour on computer use with everything glowing red.
Like most nerds I assumed it could be cured by software but got nowhere, eventually after trying a different NVidia card that was OK in another computer which stopped the computer working completely by disrupting the BIOS I thought to test the BIOS back up battery and found it down to 1 volt.
Replacing it cured all the problems !, should I have tried this earlier (the computer is of 2008 vintage rescued from the town dump)

My neighbours children love to play "KIZI" games on my computers and I have always emphasised to them that they should make a software shut down before cutting the power.
This seems to be a sensible precaution with HDD drives but is it needed with SSD drives ?
I find the edge browser superior to IE11 but have difficulty starting it up, what I have to do is open some URL that naturally reverts to Edge (the default browser) and then with the favourites imported from IE11 get the URL I want.
I would be nice if I could open it from the taskbar as I di IE11.
After a system update one is left with a large block of unwanted files labelled Windows.old if one wishes to reduce the amount of stored data to use expensive SSD drives it is desirable to get rid of this.
No normal method of deletion works I have tried using Linux that only relabels it as $recycle which does not show up in windows but can be viewed with CMD but not deleted !
If the devil played any part in the design of modern computer systems the RJ45 connector must be one of his proudest achievements this vital connector that enables our connection to the outside world is held in by a plastic clip 1mm by .2mm in size which seems designed to break off allowing it to fall out.
I shudder to think what this has cost in technician time over the years.

While staying in a friends house I Indianapolis I came across an 8 year old Samsung cell phone as I have a charger for these phones I thought I would try and revive it for use when I stay there.
The camera worked fine so I looked round for a Bluetooth dongle to get the pictures off and found one for $2.00 at a nearby garage sale and it worked fine with both the old cell phone and my 3 year old one.
When I returned I brought it with me but not the dongle thinking it would work with my regular Bluetooth but no luck.
The dongle that I left in America was supposed to work version 4 so I bought a new CRS dongle from Amazon but no luck with that either.
Bluetooth is rather a work of art but I can normally get it working and with the new dongle it is quite easy.
I really miss my Siemens R30 (IBM360 clone) of 1975 vintage it might have cost 100 times as much as a pogoplug box and only had a 10 MHz processor and 256 KB of RAM but at least it had proper connectors that bolted in with gold plated pins.
I have had 2 hours of agro because one USB socket does not work as well as another.

Equivalence theory tells me I should not be able to distinguish between acceleration and gravity but when my tall space ship is sitting on the earth I can measure a difference in G whether my instrument is on the floor or near the ceiling.
Presumably this would not happen when I was away from the Earth and accelerating in space.

As a result of taking tablets to reduce blood pressure I suffer swollen legs and feet would diuretics help.

As a boy we were taught that the nucleus of an atom consisted of protons and electrons, Neutrons like radar were military secrets we did not want the Germans to know about.
After the war we were told that this was nonsense and the nucleus consisted of Protons and Neutrons, with the discovery of Neutron stars it was postulated that Electrons could be forced into Protons by gravitational pressure so the first theory was not that far out.
how does this happen Protons and Electrons and are of different classes of particle I would have thought that any union would be impossible.
On the recommendation of Chris I thought I would try Kali to which end I made a 50Gb partition on my spare drive and downloaded a compressed ISO version from the internet which came in in 7 minutes.
I thought this won't take long ,decoded to my regular loading USB dongle , selected with the BIOS but the only result was "no system".
selected the drive on which to load it clicked on setup and the answer was not compatible had another go and it eventually let me start.
There was then a procedure putting in passwords and what not then at last it asked me to make a restart and tell it which partition to put it on.
it then insisted that it did a forensic clean up of the empty partition that looks like taking about two hours .
If I am presented with a serviceable computer with an internet connection available but is dead because the drive has been formatted is there any way I can bring it to life not having any software to hand.
I would like to experiment but do not have a spare drive to hand
