Is dark matter even real?
It's one of the most fascinating topics of conversation among space enthusiasts: dark matter. This comes as little surprise considering its theoretical nature. And yet, it may not matter how interesting dark matter is if it isn’t real to begin with. Randy sole takes such a stance in this intriguing post, encouraging some insightful responses:
N A S A has stated that the Dark Matter is in patches, how did they make that statement if did not have proof. As far as rotation of galaxies, the planet, and each solar system is it torque and that only happens when there is resistance of something that has rotation, the electron in the valance of each atom. - Cat-Ret-Jet
IMO dark matter/energy is a byproduct of fluctuations creation of temp particles.
Fluctuation is at an energy balance so no new particle stays. Conservation of energy. Temp particle though have temp energy and matter and over the size of our BB universe that could easily be dark matter and dark energy as temp products that have a net result. - voidpotentialenergy
What are the most important questions about space exploration?
This was on serhiy1635's mind this week as they pondered the future of human space exploration. Considering all of the variables involved, it’s a worthy inquiry. Here's a selection of responses from the community:
In my opinion, I think the biggest issue that needs to be resolved is long-term survival in space. That means testing of artificial gravity and radiation protection. - Woldshadw
IMO the thing that is now needed is the development of a fully reusable spacecraft to greatly reduce the cost of getting into orbit. If we continue throwing tens of millions of dollars of precision engineering hardware into the Atlantic ocean at every launch its going to act as a serious obstacle to further development. - Slarty1080
