Every time we prove something as Immortal, we find a Mortality. This is Decay. It seems as though even Black Holes have Decay. If this is the case, is there an Eternity to look forward to? Theoretically, under what conditions would the Universe need to have in order to promote a Limitless Existence? Do we currently support the movement towards such a potential? Postulate: Can the particle moved along a light beam become a wave without decay. Simply a wave of light where a particle is unnecessary? Is this a shift in current reality? Particles show decay, waves simply move and stop, bounce, and are absorbed - and created? Are particles simply a stop-mot…

Am completely new to this, and could only classify myself as a layman in physics terms, but an interesting thought occurred to me recently: While watching " Cosmos" recently, I started thinking about what was said about the expansion of the universe. If we take as a given that at the centre of each galaxy is a supermassive black hole which is consuming matter and growing as a result of this, why would our galaxy still be expanding? So what if all the matter that is being absorbed by the black hole is being turned from matter into 'dark matter'? The black hole might be an instrument which takes in matter spewing out dark matter, which would be amassing and pressing do…

How do you measure the distance of a 4.22 ly star using parallax using the earth's orbital diameter and Hubble (.1 arcsec)?

https://phys.org/news/2018-04-diamond-sky-lost-planet.html Study: Diamond from the sky may have come from 'lost planet' April 17, 2018 by Frank Jordans Fragments of a meteorite that fell to Earth about a decade ago provide compelling evidence of a lost planet that once roamed our solar system, according to a study published Tuesday. Researchers from Switzerland, France and Germany examined diamonds found inside the Almahata Sitta meteorite and concluded they were most likely formed by a proto-planet at least 4.55 billion years ago.

Their findings are published as Advance Online Publication (AOP) on the Nature Astronomy website on 16 April 2018. One of the most fundamental predictions of Einstein's theory of relativity is the existence of …

Please allow me to toss out a simple assertion as I endeavour to make sense of life, reality and the universe. My first assertion is simply that space is the ultimate antecedent simply because it can exist without anything in it but nothing can exist without space. Space can exist without neutrons, photons, protons, atoms and molecules, though these particles cannot exist without space. Space can exist without stars, planets, galaxies and black holes, though these things cannot exist without space. Space can exist without black energy, black matter, strings, deities or anything else we humans can imagine, though none of these things can exist without space. Space can…

The Chinese Space Station, Tiangong 1, looks very much like a glider i.e. a bit like the US Space Shuttle (solar panels are made of similar materials to Space Shuttle tiles with much less friction), as the German radar images show in the link below, so it most likely wasn't tumbling but yawing from left to right and pitching and rolling just like a glider would, as it comes down to land. https://www.space.com/40089-china-space-station-tiangong-1-radar-images.html Here's a basic summary of how to project the reentry time of non powered Glider Class reentry vehicles, similar to Tiangong 1, as it might prove useful in the future. It's probably a little bit e…

https://phys.org/news/2018-03-dark-galaxy.html Dark matter 'missing' in a galaxy far, far away: March 28, 2018, Gemini Observatory Galaxies and dark matter go hand in hand; you typically don't find one without the other. So when researchers uncovered a galaxy, known as NGC1052-DF2, that is almost completely devoid of the stuff, they were shocked. "Finding a galaxy without dark matter is unexpected because this invisible, mysterious substance is the most dominant aspect of any galaxy," said lead author Pieter van Dokkum of Yale University. "For decades, we thought that galaxies start their lives as blobs of dark matter. After that everything else happen…

Disclaimer: I am a brain tumor survivor 28 years and counting. This is not about that, but may explain some things. I manged to get an engineering degree with a physics minor 24 years ago and I have seen many documentaries, lectures and online classes that have conclusions based on public data that are opposite of my conclusions. Let’s call this nerd passion. I need to communicate this to the scientific community and I don’t know how, as my emails, phone calls and face to face conversations have lead nowhere. I have much to say regarding the interpretation of galactic data. The over simplified version is that it’s as easy as DERTT, and they forgot the …

There are many phenomenons of planetary activity which seem can't be explained by modern science.

I recently finished reading Peter F. Hamilton's Commonwealth Saga (which I highly recommend to any Sci-Fi fans out there), and usually he's pretty good at incorporating actual scientific concepts into his stories when the plot doesn't require him to invent various Clarke-techs, but I was hoping someone with the know-how might be able to answer something. One of the technologies that humanity develops in the series is something they call a nova bomb, which is fired into a star to cause it to go nova. But the explanation given for exactly how it works is that once it gets deep into the star it emits some kind of quantum field that causes, quote, 'A volume of the star'…

Dear science forum I have a problem with the Big Bang because of a mathematical discrepancy that makes no sense to me. As far as I can figure out, evidence proving the Big Bang is coming from electromagnetic radiation (i.e., light, ultraviolet light, infrared light, gamma rays, x-rays, etcetera) which I understand is travelling at the speed of light, approximately 300,000 km per second. Yet, we are standing on earth which is apparently hurling through space 300-400 km/s - https://www.scientificamerican.com/article/how-fast-is-the-earth-mov/ - which is less than 1% the speed of light. My problem is that I do not understand how we can be interceptin…

Is it possible that photons can not be created inside a black hole, rather than the extreme gravity preventing light from escaping?

Hi ! I created recently a space composition with After effect, a visual effect software, and I think of using the composition as a key piece for my portfolio. i'm doing my university request in a couple of months, and right now i'm writting the description of my projects. In the desciption of the space composition i'm talking about, I'd like to give a name of what I created in the 10 first seconds, but i'm not sure if I can call what I created a black hole. So, if it's not a black hole, is it looking like something known ? If yes, what's the name of the phenomenon. Here's a picture of what i'm talking about : https://imgur.com/a/3X3e0 here's the composition…

I am looking to buy an inexpensive green laser pointer to take camping and use to help show my grandson the constellations . In reading on them I have read that some cheap ones can emit dangerous levels of infrared radiation. In just browsing there looks to be some decent ones in the $50 range , if these are not the ones being referred to as dangerous. Any recommendations on a known safe laser pointer in the $50 range that are decent enough to point out constellations on a clear night?

By dissecting starlight filtering through the planet's atmosphere into its component colors, the team found clear evidence for water vapor. Although the researchers predicted they would see water, they were surprised by how much water they found - three times as …

These findings combine computer simulations with data from recent exoplanet findings, as well as X-ray and ultraviolet observations of stars and black holes. "It's pretty wild to think of black holes shaping the evolutionary destiny of a planet, but that very well may be the case in the…

Recently I saw a video where scientist believe that we should not exist. They came up with a formula which shows that during the big bang there should have been equal parts of anti-matter and matter. This would mean that matter and anti matter would constantly come into contact and exploding making it impossible for anything to survive. Also, all we see is matter all around us so scientist wonder where is all the anti-matter? This is just for fun, what are your theories on our existence considering this? I have no prior education in astronomy or cosmology but one Idea I've been able to come up with is during the big bang both anti-matter and matter came out in oppos…

What I mean is how did scientists figure out the width of our galaxy (in light-years) or how far away Proxima Centauri is? Thanks.

Everyone just ASSUMES that there's got to be life on other planets, right? I mean ... how rare can Earth actually be that it's the only planet in the whole universe with complex life on it? Also, whenever a planet is discovered that's inside its star's "habitable zone," astromers wet their pants in excitement over the possibility oflife existing on that planet. Here's something most people never really think about when they think about life on other planets: Even if there may be life on other planets, what makes you think they have the MEANS to travel through space like we do? Astronomers often consider liquid water on other planets to be the holy grail of …
