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 ?

Up until 1965 most British TV,s had very crude power supplies that injected 0.3A back into the mains, I have of6ten wondered if this had a bad effect on the transformers.

I think Alan underrates the severity of the English law in a recent case a defendant accidently killed a police officer trying to stop his car in a case where the charge would normally have been one of causing death by dangerous driving was charged with murder and despite the disagreement of the jury the was convicted of manslaughter and sentenced to 21 years imprisonment.

If the problem was acute the pilots direct view could be replaced with a television system where only one of several redundant cameras each incorporating different filters would be the only things risking damage.
I would expect such a system to introduce additional dangers and only be used if the problem became acute.

Although at present it does not seem possible to shield against gravity does it not depend on whether or not the Graviton has mass ?.
The graviton is postulated to have a mass vastly smaller than that of the Neutrino and its hard enough to shield against that but if the Graviton has non zero mass there is at least a theoretical possibility that it can be screened against

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 Victorian times it was believed that it should be possible to obtain a picture of the killer by dissecting the eyes of the vivtim

One of the limitations of obtaining information from brainwaves is that it is unethical to insert probes directly into the brain this of course would not apply if the person being interrogated had what the authorities regarded as information of value to the military

It's been on the drawing board for as long as fusion reactors!
I think the Icelanders have a love/hate relationship with geothermal power that causes a lot of contamination they like their warm apartment's and swimming pools but are not keen to have too much of it

One underwater transmission line that should be built is Iceland to the UK to tap the abundant geothermal power that can be generated there

It is well known by intelligent people that torture is pretty unsuccessful at extracting reliable information even the GESTAPO knew that but on film and TV it is always displayed as very effective.
My interest was whether reliable hi-tech methods are being developed.

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.

Could we get some idea by comparing the strength of the nuclear force to that of gravity and the distance over which it operates ?.
I would be interested to know whether the FBI have actually generated a password and accessed data in the phone or simply found a way to bypass the self destruct system.
For a brute force password generation to work you need a way to input trial passwords rapidly you cannot do it by pressing buttons !.

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.
Cells, Microbes & Viruses / Re: Should CRISPR gene-edited organisms have different regulations than "GMOs"?« on: 29/03/2016 23:12:16 »
It is a tragedy that two technologies that would yield great good for mankind are held back by ill informed prejudice I refer of course GMO and nuclear power.
I take it that if the energy to raise this 5Kg mass has come from an Earth bound source the Earth has also lost the same amount of relativistic mass.
Due to the daughter atoms from the spit uranium atoms having less mass and Neutrinos carrying off some.
On further thought I have convinced myself, where does the energy come from to lift the roller coaster ? we break up a few Uranium atoms in our reactor and export the energy obtained hence the Earth must have become a little less massive.
We have a closed system so the roller coaster that receives that energy must have gained mass!.
