Orange Dwarf Star Set to Smash into The Solar System

[Nihilgeist Profile]

Well there comes a time, when Earth is apparently long gone the Milky Way will collide with the Andromeda galaxy this will make "our" galaxy two times, maybe three times as big as it is now.

Andromeda while we speak as well as the Milky Way for that matter should go on a diet, because they're eating like starved cannibals.

The thought of this will happen is mind blowing on itself.

Indeed it is mind blowing. I love the simulation videos because it puts more of a personal perspective on what will happen rather than just an abstract idea of the future.

That is why I love this one, if we did survive up to the point and during the galactic cannibalism:

7. Future Sky (6:37)

(See Spiral Metamorphosis for an introductory description of the collision of the Milky Way and Andromeda)

We present the collision here from the interesting perspective of the Sun using two all sky views. The first view projects the full 360 degrees of the sky onto an oval map using aan Aitov projection while the second view show one hemispheric dome of the night sky projected onto a circe. In the sky views, one particle is identified as the sun within the model of the Milky Way and our view is always from this perpective with our attention directed towards the central bulge of the Galaxy making for a mind boggling spectacle!

The arch of the Milky Way is apparent at first as a band of stars and tiny Andromeda is seen scrolling past beneath the arch but slowly growing in size as it approaches. When the 2 galaxies intersect, the sun is flung out far from the colliding pair of galaxies and our view oscillates between a remote view of events to a wild ride right through the centre of the galactic bulge! The orbit of the sun is no longer circular but now follows a convoluted pattern with the distorted gravitational field of the merging galaxies. A final look back from the far flung sun shows the final merger of the two galaxies.

Nice one I will keep this for myself.

Galaxy's alway collide in space, so first our solar system was in another galaxy.

I really enjoy this stuff, because it also get us closer to the big question we all have.

Stephen Hawking: "Humans Have Entered a New Stage of Evolution"




Although It has taken homo sapiens several million years to evolve from the apes, the useful information in our DNA, has probably changed by only a few million bits. So the rate of biological evolution in humans, Stephen Hawking points out in his Life in the Universe lecture, is about a bit a year.

"By contrast," Hawking says, "there are about 50,000 new books published in the English language each year, containing of the order of a hundred billion bits of information. Of course, the great majority of this information is garbage, and no use to any form of life. But, even so, the rate at which useful information can be added is millions, if not billions, higher than with DNA."

This means Hawking says that we have entered a new phase of evolution. "At first, evolution proceeded by natural selection, from random mutations. This Darwinian phase, lasted about three and a half billion years, and produced us, beings who developed language, to exchange information." But what distinguishes us from our cave man ancestors is the knowledge that we have accumulated over the last ten thousand years, and particularly, Hawking points out, over the last three hundred.

"I think it is legitimate to take a broader view, and include externally transmitted information, as well as DNA, in the evolution of the human race," Hawking said.

In the last ten thousand years the human species has been in what Hawking calls, "an external transmission phase," where the internal record of information, handed down to succeeding generations in DNA, has not changed significantly. "But the external record, in books, and other long lasting forms of storage," Hawking says, "has grown enormously. Some people would use the term, evolution, only for the internally transmitted genetic material, and would object to it being applied to information handed down externally. But I think that is too narrow a view. We are more than just our genes." The time scale for evolution, in the external transmission period, has collapsed to about 50 years, or less.



Meanwhile, Hawking observes, our human brains "with which we process this information have evolved only on the Darwinian time scale, of hundreds of thousands of years. This is beginning to cause problems. In the 18th century, there was said to be a man who had read every book written. But nowadays, if you read one book a day, it would take you about 15,000 years to read through the books in a national Library. By which time, many more books would have been written."

But we are now entering a new phase, of what Hawking calls "self designed evolution," in which we will be able to change and improve our DNA. "At first," he continues "these changes will be confined to the repair of genetic defects, like cystic fibrosis, and muscular dystrophy. These are controlled by single genes, and so are fairly easy to identify, and correct. Other qualities, such as intelligence, are probably controlled by a large number of genes. It will be much more difficult to find them, and work out the relations between them. Nevertheless, I am sure that during the next century, people will discover how to modify both intelligence, and instincts like aggression."

If the human race manages to redesign itself, to reduce or eliminate the risk of self-destruction, we will probably reach out to the stars and colonize other planets. But this will be done, Hawking believes, with intelligent machines based on mechanical and electronic components, rather than macromolecules, which could eventually replace DNA based life, just as DNA may have replaced an earlier form of life.

I don't see the relevance with this topic, but what might be possible is, we can use the universe itself to colonize other planets, because off the cannibalism of galaxies. Maybe we can set our DNA structure more to the point of making use of universe speeds and dimensions, but that would take maybe thousands of years to establish.

Interesting story though! I really like Steven Hawkins for his intelligence and remarkable sense of evolution.

That will cause some comets to hit some if not all the planets within our Solar System.

This might be the prediction of total chaos.

The Oortcloud will cause human extinction eventually that’s for sure. If not something else will wipe us out of the system.

Nice finding Marduk!
