    Nuclear fusion reactor could be here as soon as 2025

    That is indeed a trite expression. Do you have any specific criticms of the seven open access, peer reviewed, articles from the SPARC team that back up their assertion that a fusion reactor could be running by 2025? I personally don't have the background necessary to evalaute their merits.

    US military eyes nuclear thermal rocket for missions in Earth-moon space

    Do they really need a fast rocket just to be "aware" of what is happening between the earth and moon?

    Are some black holes wormholes in disguise? Gamma-ray blasts may shed clues.

    FWIW, that would undercut the entire argument linking blackholes and wormholes presented in the article. Namely, that observed gamma-ray blasts from black holes could mean they are wormholes with matter entering both ends and colliding: "Anything entering one mouth of a wormhole would exit out...

    My 12 year old self always knew this to be true. ;)

    Earth life may have traveled to Venus aboard sky-skimming asteroid

    From the paper: " The asteroid belthas been in steady-state for∼3.7 Gyr, implying that during this period,∼6e5 Earth-grazing asteroids of mass∼60 kg have impacted Venuswithin∼105yr of interacting with the Earth. " But they don't try to quantify the chances of those asteroids picking-up...

    Earth life may have traveled to Venus aboard sky-skimming asteroid

    " Furtherwork is needed to investigate the existence and abun-dance of microbial life in the upper atmosphere, partic-ularly at the altitude considered here,∼85 km, at which Earth-grazing object would avoid significant heating. " So, their argument hinges on the assertion that object...

    After a tantalizing discovery at Venus, what could an astrobiology mission look like?

    Maybe they didn't originally form where they are today? https://www.space.com/venus-life-earth-grazing-asteroid

    Earth life may have traveled to Venus aboard sky-skimming asteroid

    Looks like this article touches on this topic: https://www.space.com/phosphine-venus-clouds-chemical-explained.html "Phosphine is a chemical compound made up of one atom of phosphorus and three atoms of hydrogen, and scientists have also spotted it on Earth, Jupiter and Saturn. On the gas...

    China's Chang'e 3 lunar lander still going strong after 7 years on the moon

    No stars in the background! Clearly another hoax! ;)

    After a tantalizing discovery at Venus, what could an astrobiology mission look like?

    Sure, but what's more promising than Venus at the moment, not already being investigated, and within technological reach? Also, people "getting carried away" can lead to MORE funding for space projects. Regarding negentropy, the only source I really found on that was this line from Wikipedia...

    After a tantalizing discovery at Venus, what could an astrobiology mission look like?

    IMHO, if people "getting carried away" leads to funding for more probes to investigate the hypotheses, then it's a good thing. I'm not sure what you mean by negentropy in this context , but it has been suggested that UV from the sun could be an energy source for atmospheric life. I'm not in a...
