A new study suggests Proxima Centauri could sustain liquid water on its surface[ /quote] Wrong head line. Proxima Centauri is a star. Planet PCb could sustain water that is another thing. Many use "Proxima Century " for the star as well as the (solar) system consisting of all the planets.

Amber G.

Adding to a previous topic/post .. - No one really knows where (or even if) is the nearest planet with life outside our solar system. But serious people (even wiki : ) suspects there are more than previously thought.. even reports of rocky planet near our own Alpha century , and Proxima century.. An...

^^^TO add: FWIW * (My personal views): DAE Chairman Sekhar Basu seemed pretty happy in one of the talk he gave and said something like " India's Department of Atomic Energy performed "exceptionally well" in 2017. Also there is concentrated effort to get more nuclear physicists and eng...

Amber, great experience. I have have heard/read that the whole disk was put togather by Carl Sagan in 6 weeks. Yes! The idea of "disk/record" was added *much* later in the project. So things had to move incredibly fast and budget was very low. As said, whole greetings business was done by...

Amber G.

This recent discussion brought me a thought - The space record (see discussion above wrt to Sagan) with greetings in hundreds of languages spoken is on the way to other star systems. Greetings in Rajasthani (spoken) is some thing like .."Ram Ram pahunche.. ham sabhi athe kushi ho, tum vahan kus...

Few comments to add clear some issues: Second, the events are correlated in time with an event observed in space. I.e a bright flash, or burst of some electromagnetic energy. India's Astrosat space telescope played a role in that since it can see over a broad range at different spectral wavelengths....

For LIGO, the precision is about BILLION (Yes, a billion) times more ! This is almost unbelievable. IOW i f you take the distance between earth and Alpha Century (4+ light years).. it measures/detects the variation of the order of thickness of a hair. = Just think about that. How are they able to i...

Ligo is a fancier version of the Michaelson-Moresley interferometer first use to detect the constant speed of light back in the late 1800s. Basically it is an interferometer that if disrupted due to compression or expansion of space-time can be noticed. Just a comment for perspective: One of the mo...

^^^ Don't want to spoil the fun but just to put things into perspective... If we make 1000X (Yes 1000 times) progress in propulsion system it will take about 100 years just to reach Alpha Century -- another 4 years or so just to send the message back to earth :). This will require power source as st...

One aspect of UD3 and Pakistan many do not realize because it is not taught in scientific world - more to do with Pakistan than neutron initiators --

i am not disputing putin did it, or trump knew it etc. putin has so far never accepted interference. before helsinki, or in helsinki as well - except the 'yes i did' clip you posted. - which points to possibility that he was answering yes twice, but to first question. really doubt that putin would ...

I don't think he said Yes for both the questions. It looks like that, but its possible he was responding to first question, without realizing second question, or realizing it too late.

AmberG, With your academic background this UD3 thing can work? Where will they get D3?
