Ccontrarian replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.I discount certain aspects of it. The recent data from the JWST might provide some evidence to support this. I keep reading about how...

Ccontrarian replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.What is the evidence for this? None. Smaller stars have been forming since the cosmic dawn, and cranking out lots of heavy elements by...

Ccontrarian replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.All larger stars produce most of the natural elements that we know of, and they have been doing this for billions of years. These...

Ccontrarian replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.Primordial black holes are also postulated to have formed very early after the BB (before or during the formation of H and He), and...

Ccontrarian replied to the thread SpaceX launches Starship Flight 9 to space in historic reuse of giant megarocket (video).One possible reason is a hardware problem in one of the engines may have caused excessive "harmonic response" in the upper stage. This...

Ccontrarian replied to the thread SpaceX launches Starship Flight 9 to space in historic reuse of giant megarocket (video).I understand your mistake. It happens to me from time to time, sadly.......... And I understand the use of so many engines. But it...

Ccontrarian replied to the thread SpaceX launches Starship Flight 9 to space in historic reuse of giant megarocket (video).It actually burns liquid methane, which is very cryogenic and much more difficult to handle than propane. Also of concern are those 33...

Ccontrarian replied to the thread China signs deal with Russia to build a power plant on the moon — potentially leaving the US in the dust.And that is part of the problem. The reactor is going to be assembled on the Moon. It is not going up in one go. The problems which...

Ccontrarian replied to the thread China signs deal with Russia to build a power plant on the moon — potentially leaving the US in the dust.Hard to imagine fuel rods staying intact during a de-orbit. Unless they are designed to survive (unlikely), they will disintegrate. The...

Ccontrarian replied to the thread China signs deal with Russia to build a power plant on the moon — potentially leaving the US in the dust.If the rods disintegrate on launch (very likely), they would spread radioactivity over the "landing' zone, which could pose hazards to...

Ccontrarian replied to the thread China signs deal with Russia to build a power plant on the moon — potentially leaving the US in the dust.Good to see these two spending a lot of money on space exploration rather than on weapons of war. China is doing too much of that...

Ccontrarian replied to the thread The moon doesn't have a magnetic field, so why does it have magnetic rocks?.The Moon's magnetic field strength in its early days is open to debate. Mars has a similar magnetic surface, with the most highly...
