Helio's latest activity
-
Helio replied to the thread Scientists question possible signs of life on exoplanet K2-18b in new study: 'We never saw more than insignificant hints.One other thing worth noting, the original public presentation for DMS came with the optimistic statement of "I kid you not." ;) -
Helio reacted to rod's post in the thread Scientists question possible signs of life on exoplanet K2-18b in new study: 'We never saw more than insignificant hints with
Like.
Others are reporting a bit more skeptical thinking about life on K2-18 b now. Hopes for alien life dim as doubts emerge over exoplanet... -
Helio replied to the thread Scientists question possible signs of life on exoplanet K2-18b in new study: 'We never saw more than insignificant hints.Oops, I see my revised program ignored the given radius of the exoplanet, thus it calculated its radius based on a rough density table...

Helio replied to the thread How the runaway greenhouse gas effect can destroy a planet's habitability — including Earth's.I'm curious if this paper had peer review. It's published in Astronomy and Astrophysics, but why not the geophysical journals? I'm...

Helio replied to the thread Scientists question possible signs of life on exoplanet K2-18b in new study: 'We never saw more than insignificant hints.This comes with little surprise to those who, like me, are pessimistic for life on exoplanets hosted by red dwarf stars. It is in the...

"We don't serve tachyons here." A tachyon walks into a bar.

Helio replied to the thread Can there be a speed higher than light.Yes. That is essentially a law in Relativity. This was the original view of the speed of neutrinos. But from Dr. Davis, and lots of...

Helio replied to the thread Is there really dark matter?.Do black holes exist? None have ever been observed, right?
-
OK. As you say "fun, ifs", so I am not being critical - just commenting :) You cannot apply PV=nRT to open systems. After you have...

Helio replied to the thread Is there really dark matter?.No. "excess gravity effects require an explanation, these effects are caused by DM, therefore objective evidence?" You're trying to...

Helio replied to the thread Scientists find rare double-star system where one star orbited inside the other.Interesting. I was going to suggest a sooner than later dynamic merger, but pulsars rotate rapidly, so perhaps the tidal friction will...

Helio reacted to Admin's post in the thread Scientists find rare double-star system where one star orbited inside the other with Like.
Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner. Scientists find...

"AFAIK, the only objective evidence comes from only gravitational effects by DM." Taking into account your previous posts are you...
-
Helio replied to the thread Is there really dark matter?.Yes, this is DM in a nutshell. Scientists have simply put a label (ie DM) on whatever it is that is causing the excess gravitational...

Helio replied to the thread Is there really dark matter?.AFAIK, the only objective evidence comes from only gravitational effects by DM. But there are many numerous hypotheses that are trying...
