I did some research on the rise of cosmic rays.

There are many hypotheses , but the most accepted is that when solar activity is intense the heliosphere and solar wind become more powerful and therefore we are more shielded from the rays coming from the stars that are outside of our system.

Seem that the current solar cycle ( SC24, started in Jan 2008 and still ongoing) untill now was weaker of the previous ( may 1996- jan 2008 ), ths may explain the current increase of cosmic rays.

Pretty sure most of you heard about the Space X landing.

 

This could change space exploration forever, especially since the cost of replacing the primary module is now practically negligible.

 

 

News story about it here.

 

 

SpaceX finally stuck a sea landing Friday, when the company's first-stage booster glided smoothly to a hover before landing on a floating droneship.

 

Now the aerospace company will prepare the booster for a second flight -- a move that could be key to the company's plans for cheaper space tourism, satellite launch and eventually flights to Mars.

In a post-launch press conference Friday, company Chief Executive Elon Musk said the Falcon 9 first-stage could be relaunched on an orbital mission as early as June.

I think that within our current astronomological understandings, there is reason for us to believe that dark matter/dark energy are the discrete material we are looking for that can confirm the existence of "Unus Mundus"...

Dark Matter and Dark Energy may even be universal polarities respective to matter within itself. I happen to believe that they might be the source that reveals how the universe creates order from so much chaos. Like coincidences being a thing and stuff, which, may all very well be more real than we give them credit for. If Unus Mundus were to be real, it more than likely would confirm the existence of the Collective Unconscious too, which is a psychic realm built off of the driving forces of Emergence.

This may seem like it's kinda hard to believe and all, but its not, its just not. There exists a fundamental realism that is not mean't to exist in some of the ways we currently mythogolize such realism to strike true. As such, it occurs to me that even the most decisive person can find all his merit from being actively deceived by the universe, which, to me, seems to play a fairly substantial role at accelerating our very own basis of knowledge.

I'll get to unconscious minds now. Now what may seem hard to believe is the reason we have not found the unconscious mind yet. But, the reason we haven't, is because we haven't figured out who/what the actual driving forces are for Emergence. It's all actually paradoxical, because if it 'is' in fact your unconscious mind who drives your emerging patterns and such, would that mean you are existing in two separate ways, just like how atoms/electrons can be in two places at once? Well...maybe...or maybe theres just much more to this than we think. Thats what I think anyways...

Unus Mundus is a fascinating concept, but i think nobody con say for sure it is correct, but this is true even for many other things.

Dark Matter is a very interesting topic, even if it seems too generic, in the sense that I think we  cataloged as dark matter too many different things we do not know.

For the dark energy...i have many doubts on the fact that the dark energy is reponsible of the universe expansion.

I will explain : scientists have calculated  the distance between galaxies , and came to the conclusion that the universe is expanding, the calculation is based on the concept that explosions of supernovas "Ia" produce a significant peak of absolute brightness, which is almost equal in all the explosions of this type of supernova, because of the relative uniformity of the masses of white dwarfs that explode as a result of processes accretion.

But here the part that make me doubtull : we are absolutly sure that ALL explosion os supernovas "Ia" is relally so similar ? if not these calculations are all wrong.

So basically...you believe that the cosmological constant is wrong within things like the Friedmann equations? Im just trying to understand your point of view more...

Ill check out the link in a bit. I have much to do in like 15 min. So yeah.

Edit: Yeah I can see your point in how Supernovas have this potential to them. Einstein hated the idea of the universe accelerating, or rather, he didn't approve of the cosmological constant, as such massively based phenomena would have to be approximated in a way that would otherwise be distraught for us within calculating/theorizing an ad hoc thats relative to our current sciences and what not, but thats just me saying that!

I'm happy for Einstein lately! His theory of gravitational waves is in fact, fact! Its pretty cool. I dunno what that implies for us in the future, but maybe dark matter/dark energy will be found from the use of that new machine or somethin...maybe an entirely new theory will emerge too! Its pretty cool to wonder!

seem that was found evidence of 2 ancient tsunami on..Mars!

The sun is spotless, that mean that the solar cycle 24 is is entering in  the solar minimum, this does not mean that the cycle is complete, the cycle will be considered closed only when a sunspot with opposite polarity will appear in the visible side of the sun.

According the forecasts that will happen in 2019-2020.

Is the occasion to check if there really a connection between low solar activity and increase of cosmic rays.

another dwarf planet was discovered, 2015 RR245...i will let you know when more info will be know, for now seem that is a little world past neptune that take 700 years for a revolution.

I'm looking even for news on JUNO, that will study magnetic field and core of Jupiter.

I have a question I would like answered. Is there an edge to the universe? Not the known universe but an actual edge to the expansion of the universe. Is there any real information regarding the shape of the universe? People think it is flat but that is within a margin of error. Is there any evidence supporting an edge of the universe or an infinite universe? I've heard a lot of conflicting answers. Also if the universe is always the same size but is expanding relative to itself, how is that possible to measure? Several questions I guess. Thanks.

Recently I've been getting into astronomy more than ever. I'm in complete love with the subject now and hope to learn a lot more by the end of the year.

 

strike: I think there is an edge? I'm still trying to grasp my head around the universe itself... it makes my head hurt a lot. Well, I heard there is an edge based on a lot of common and more accepted theories. But who knows? I think the universe being a mystery is better than it being known and understood. That isn't to say we should quit learning about it but I just prefer it a mystery as it's more exciting and amazing that way for me.

WHAT HAS EDDY DONE TO YOU!!???

 

 

In all seriousness and in response to some of strike's questions, I don't think it's possible to know exactly if the universe is infinite or not nor what the shape of the universe could be.

 

On the largest of scales spacetime does appear to be very flat. Measurements of the CMB (cosmic microwave background) and of the distribution of galaxies confirm this flatness with high, but not infinite precision. If spacetime is indeed perfectly flat, then, according to Einstein, the universe is infinite. However, like I said, we can't measure if the universe is perfectly flat or not.

 

Think of it like this. The surface of Earth looks flat to us because we can't see it's curvature locally. When you fly off into space and get a different perspective, the Earth is clearly curved. It could be that the curvature of the universe itself is so small that we can't see far enough to detect or measure it.

 

This disparity allows there to be multiple theories as to how the universe is shaped; one, as I already mentioned, could be that it's perfectly flat. The universe could also be the surface of a hypersphere (a 4-dimensional sphere). We just can't know the shape of the universe with our current knowledge and technology.

[strike]

Beyond the universe being perfectly flat or being a shape that has no edge such as a hyper sphere, is it possible for the universe to not have an edge?

Yeeees, continue to love astronomy. My job is accomplished B)

just like DaviAwesome said, accoding Einstein if is flat is infinite and there no edges.

For me, if is a sphere, it must have a sort of edge.  

I like the idea of the sphere, but for what we know it may be eveything, even the shape of a donut.
