maroonlegions Posted December 12, 2017 Share Posted December 12, 2017 Wonder what the outcome of this investigation on the first interstellar asteroid will be. Seems it's like nothing seen before. The VLT discovered it this year. Here is a snippet from the link provided below. "On October 19th, 2017, the Panoramic Survey Telescope and Rapid Response System-1 (Pan-STARRS-1) in Hawaii announced the first-ever detection of an interstellar asteroid, named 1I/2017 U1 (aka. ‘Oumuamua). Based on subsequent measurements of its shape (highly elongated and thin), there was some speculation that it might actually be an interstellar spacecraft (the name “Rama” ring a bell?). For this reason, there are those who would like to study this object before it heads back out into interstellar space. While groups like Project Lyra propose sending a mission to rendezvous with it, Breakthrough Initiatives (BI) also announced its plans to study the object using Breakthrough Listen. As part of its mission to search for extra-terrestrial communications, this project will use the Greenbank Radio Telescope to listen to ‘Oumuamua for signs of radio transmissions. link;. Breakthrough Listen is Going to Scan 'Oumuamua, You Know, Just to be Sure it's Just an Asteroid and Not a Spaceship. - Universe Today Using the Greenbank Radio Telescope, Breakthrough Listen plans to "listen" to 'Oumuamua to see if there are any signs of alien transmissions.

FWJ Posted December 12, 2017 Share Posted December 12, 2017 On 25/05/2017 at 15:31, maroonlegions said: I see Tabbys Star is at it again. This is all about the sudden dimming of an otherwise unremarkable star 1300 light-years away in the constellation Cygnus. KIC 8462852 or ?Tabby?s star? . It has dimmed like this several times before, prompting some researchers to suggest that the mega-structures of an advanced alien civilisation might be blocking its light. Of course this has still to be proved but based on new data from numerous telescopes?it?s doing it again, the dimming that is,giving rise to the claim that something is passing by the star that is causing its light to dim. One other theory is that the star is "variable" or is surrounded by dusty clouds or dusty comets or that planets around it had collided or were still forming and that was causing the dimming. ?This is the first clear dip we have seen since [2013], and the first we have ever caught in real time,? says Jason Wright, an astronomer at Pennsylvania State University in State College. If they can rope in more telescopes, astronomers hope to gather enough data to finally figure out what?s going on. ?This could be the first of several dips about to come,? says astronomer David Kipping of Columbia University. ?Many observers will be closely watching.? KIC 8462852 was first noticed to be dipping in brightness at seemingly random intervalsbetween 2011 and 2013 by NASA?s Kepler telescope. Kepler, launched to observe the stellar dimming s caused when an exoplanet passes in front of its star, revealed that the dimming of Tabby?s star was much more erratic than a typical planetary transit. It was also more extreme, with its brightness sometimes dropping by as much as 20%. This was not the passage of a small circular planet, but of something much larger and more irregular. link; http://www.sciencemag.org/news/2017/05/star-spurred-alien-theories-dims-again https://en.m.wikipedia.org/wiki/Dyson_sphere Quote Link to comment Share on other sites More sharing options...

maroonlegions Posted December 13, 2017 Share Posted December 13, 2017 (edited) Back to the interstellar object. Astronomers are far from being fools. They know exactly when things dont fit into a natural explanation. This object does not fit into one at present. Even if this object is entirely natural , its mere present is a somewhat nice drill for the public, a sort of educational example of how one day tings cold turn out with science facing a genuine unknown as we probe and push our instruments deep into the cosmos. Except this object strangely enough looks like it came on its own accord. Edited December 13, 2017 by maroonlegions Quote Link to comment Share on other sites More sharing options...

Maple Leaf Posted January 29, 2018 Share Posted January 29, 2018 The idea of a multiverse is exotic, but certainly shouldn't be scoffed at. If there's one thing we've learned about astronomy, is that we shouldn't be too quick to rule anything out. After all, prior to the 20th century, no-one had even thought of wormholes, quantum mechanics, or dark matter. And most astronomers thought that the universe was static, until the 'big bang' theory was proposed. Finding strong evidence for a multiverse is another issue.

There's nothing wrong with being a skeptic, but you have to accept that not everything in science has to be proven in a laboratory before it becomes true. For example, Albert Einstein rarely set foot in a laboratory. He did his most famous work, his theory of General Relativity, with nothing more than a pencil and paper. That wasn't pish then, and it isn't pish now. What he proposed consisted purely of mathematics, but countless observations since then have confirmed the accuracy of what he calculated. Similarly, when Copernicus proposed the heliocentric solar system, it was all mathematics. You don't have to "actually go" somewhere to make him right.

It's actually the 'Hubble Constant' which is used in modern astronomy/astrophysics. It's a unit of measurement which tells us the rate of expansion of the universe. If, for example, one observation informs us the universe is doubling in size every 10 billion years and a later one informs us it's now taking 8 billion years, then clearly the rate of expansion is increasing exponentially. Which is exactly what's happening. Quote Link to comment Share on other sites More sharing options...

It's not happening at the 'peripherals', because there are none. It's happening everywhere else though. The distance between galaxy clusters, for example, is increasing but not because the clusters themselves are moving due to some energetic force, it's because the space-time between them is expanding exponentially. Science does not understand why, as space-time expands, its properties (whatever they are) do not 'dilute' as would be expected. One of the two great unexplained mysteries; the other being 'dark matter'. No, there aren't any 'new' stars or planets being magically invented. New stars, galaxies and planets are generated from existing matter as a result of gravity. All the matter there is, and ever will be in this universe, was created at the Big Bang.

The universe is effectively a mind-bogglingly, vast recycling plant. Dark Matter yes, but let’s not forget the hypothetical entities of ‘Inflation’ and ‘Dark Energy’. The theory relies on these fudge factors and can’t survive without them. No doubt the ‘Big Bang’ will go down in history as a stepping stone to a greater understanding of the universe. However it’s implied that the ‘Big Bang’ model explains the origins of the universe, when that is not the case.
