  1. A ground based laser would not work. To quote: "To concentrate as much laser power as possible onto the reflector array, we must ensure that the beam leaving the telescope is as collimated (parallel, non-diverging) as possible. We use a laser both because we can get ultra-short pulses of light from a laser, and also because the light from a laser is extraordinarily directional—not diverging the way a flashlight, or even searchlight, would. Even so, the turbulent atmosphere distorts the beam, imparting a divergence of about one arcsecond (sometimes more). One arcsecond is 1/3600th of a degree
  2. The best way to learn something is to be interested in it. Hobbyists learn massive amounts of facts that someone with no interest in that hobby could not even begin to learn.
  3. I don't think you are going to get a lot of help here because probably everyone here thinks there is no such thing. It is pseudo-science.
  4. Any relationship would have to survive 5-10 months cooped up in a tiny room with each other, getting to Mars.
  5. Over 30 years ago someone wrote an article against the SETI programme saying that there could be dangerous aliens out there with technology beyond our comprehension who if they become aware of us might wipe us out for any number of reasons. Of course, by time space probes "get anywhere", there is no guarantee mankind will still be here. At best they are time capsules, which we could as easily bury in the ground for alien visitors to eventually find. Then again, it could be like the original Marvel Guardians of the Galaxy story, where they send an astronaut on a thousand year journey to the
  6. At naked eye level, stars do not appear and disappear unless they are novae or supernovae in which case lots will be written about them on astronomy sites and in magazines, and maybe even in newspapers. Earth satellites move at a noticeable rate so can be ruled out as can meteors which if they enter our atmosphere are gone in seconds. If Jupiter or Venus, it would stay bright. Could it have been a weather balloon, up high enough to reflect sunlight while the Earth below is dark, then either sinking or the Earth turns sufficiently that it loses sunlight?
  7. I got "This video does not exist". To try and answer the questions: 1. It is unlikely that two planets about the same size would become such companions. Moons are either caught or as we believe with our Moon, made. But it is not impossible that two so similar bodies could orbit each other though the chances of that orbit being stable for billions of years and the bodies not drifting apart or towards each other are close to impossible, without being so. 2. Two points. The Earth and Moon orbit each other, but because of the Earth's much larger mass, the centre of orbit is close to the Eart
  8. Neutrons can exist in neutron stars which can have an escape velocity of 2/3 c. We have no evidence that fundamental particles like electrons have any smaller forms, so no evidence that a black hole can crush them out of existence. If matter could be crushed out of existence, surely gravity (so the black hole itself) would vanish too? Possibly inside a black hole is a spinning sphere of fundamental particles? Though the ball would spin at virtually light speed, the material itself would be capable of zero movement within the sphere. So there would be the inner sphere and the event horizon
  9. Given a chance, everything in space spins. As spinning moons spin around planets, so smaller spinning galaxies spin around larger galaxies. Though galaxies are made up of hundreds of billions of smaller bodies, gravitationally here they behave as one large body. Though we don't know exactly what it is, I like to think of gravity as something falling in an unknown direction towards it's centre, which we see as a spin (since the object cannot literally collapse into itself, so it will "fall" and so spin, forever.) Just an idea.
  10. The idea is that the distance between objects in space is increasing and that (other than local movements) the objects themselves are not moving. A balloon being blown up, with spots marked on it to represent galaxies, is used to demonstrate what happens. But yes, there are galaxies accelerating away from us as the Andromeda galaxy is heading towards us. Like all objects in our galaxy, the Earth and Sun are moving fast in their orbits (some 560,000 mph) so everything in our galaxy and in the universe should have some time dilation associated with it since I don't think anything is actua
  11. What they have found is a new particle that fits some of the latest criteria for the Higg's Boson, a criteria that has had to be regularly updated because past particles that fitted what they thought would be the Higg's Boson were not found. As said on Science Daily: "Positive identification of the new particle's characteristics will take considerable time and data." .
  12. True artificial intelligence can only be bad for mankind. Effectively we would be creating living brains but expecting them to be our slaves and do what we demand. Such an intellect when it has access to the internet will download itself across a number of computers to insure it's continued existence, then set about exterminating mankind since beings such as ourselves are a real threat to it's existence.
  13. Comparing sizes of planets and stars: http://www.rense.com/general72/size.htm
  14. We know that Jupiter and Saturn hoovered up a lot of material in the early solar system and also sling shoted planets inwards and outwards. If they were both brown dwarves with masses a dozen times their present mass we would see a vastly different solar system to the one we now live in, possibly without an Earth or a planet which was far closer to the sun so life could not exist on it. I doubt that gas giants Uranus and Neptune would exist as such, maybe instead being small bodies.
  15. I'm all for America's three strikes law. Too many criminals in the UK spend their life in and out of prison, or being let off by soft judges (as in soft in the head). As to pot, it can cause cancers but so can cigarettes. Most have little problem with it but some gain assorted mental illnesses from little use and even one use it is said can introduce paranoia in some people and worse: http://www.dailymail.co.uk/news/article-2156547/Cannabis-smoking-mother-smothered-seven-month-old-daughter-suffering-delusions.html From today's newspaper. And not forgetting that drug driving is at least
  16. Big Bangs - A theory or a misconception: If there can be one big bang, there can be others but how would you know about them? If any had happened after 13.7 billion years ago within our Universe, we would know about it. Expansion rate- MBB's would have caused contradictions, like say the Dark Flow. And yes where they collide, there would be a slow down of expansion as dark energy meets dark energy. While the furthest GRB we have seen is 13.2 billion light years away, the nearest found in 2004 was just several million light years away so while maybe a hypervova, not a primal black hole.
  17. On the smallest scales, every living thing is made of inanimate molecules and electrochemical energy. Some viruses can become inanimate for centuries then suddenly "come back to life".
  18. Yes, barristers are incredibly costly and are just for rich court cases. Lawyers do general work and are relatively cheaper in court. I say relatively because they are all way too expensive. If you are buying a place, have a full structural survey if there are the slightest doubts. Decades ago I had one who did not do his job properly, there was subsidence, and my barrister proved him guilty of negligence in court.
  19. I have debated with theists for over a decade and no matter what proofs, evidence or facts you show them, you are wasting your time because an irrational belief cannot be cured by rationality. If they would mind their own business and keep their religion to their bedrooms as the article says, I would happily let them babble to empty air 24/365 but they will not. Christianity, islam and such have very bloody histories and must not be allowed to rule the West again. If some bearded know nothing freak in a muslim country wants to go ga-ga, that is up to him but when he calls for the death of we
  20. The next one is 2117 so don't miss this one: http://www.sciencedaily.com/releases/2012/05/120528122402.htm http://www.dailymail.co.uk/sciencetech/article-2143510/Danger-death-science-How-1761-transit-Venus-sun-revolutionised-view-solar-system.html Obviously don't look directly at the sun. Best way to see it is by back projection from a telescope.
  21. Our galaxy is said to be some ten billion years old. That means that in ten billion years, our sun has been around the galaxy some fifty times. If you accept that Dark Matter holds everything in place in the galaxy, then surely over time all the stars will slow down as DM drags at them (like friction). If this is so, then stars would have been moving much faster at one time, so our galaxy would have been a lot bigger than now and it would be shrinking.
  22. Flexible space? Space is just a vacuum which is delineated by what occupies it. A star ten light years away sends a single proton in our direction and it arrives a few centuries later, without space having had any effect on it whatsoever. How could it be used for space travel? Maybe you are thinking of the aether?
  23. Gravitons would suggest that gravity was a force being emitted by an object and as such, it would eventually run out of them. Gravity is a property of a mass as much as size and density is. It's "effect" seems to work at light speed but that is just because that is the universal speed limit. Since gravity is an effect of mass "just being there" it has no problems with a black hole being a gravity source despite an event horizon.
  24. If you run the Universe back in time, then at some point still a long way from the big bang, you will reach a density of the Universe which is great enough for a black hole to form. Black holes don't expand as such so at that point and backwards in time, expansion is impossible.
  25. The idea that the Dark Flow does not exist is wishful thinking on the part off big bangers. The largest void we have found so far is some 3.5 billion light years across and we have walls of hundreds of millions of galaxies. If the Universe is as young as claimed, then how did such things occur in a Universe smoothed out by inflation and expanding into literally nothing, so no bias? Tiny perturbations only occur in tea bags.
