    Best answer: OK just read through your question a couple of times and I can't understand what the difficulty you're having is.

    "Down" to us is a relative indicator of wherever the force of gravity is pulling to. People on the other side of the world will be upside down relative to you, but then relative to them, you're the one who is the wrong way around. Remove gravity from the situation and relative directions like up or down start to mean very little.

    So a couple of minutes and a collision with photoshop later... is this what you're visualising?

    A bowling ball would give negligible gravity, unless you made it from some form of degenerate matter.

  • Should I walk around Mars without a spacesuit?

    Best answer: The surface of Mars is colder than Antarctica and the atmosphere is much, much thinner than the top of Mt. Everest, and has a higher CO2/O2 ratio than the breath you're breathing out now.
    So good luck with that.

    Best answer: <QUOTE>I've read that there a few projects to send humans to Mars as soon as 2024. </QUOTE>

    As with the majority of things in life, it depends on who'll pay for it. Remember that the lawyers, managers and engineers who plan, design, build, test and put in operation those things don't live out of air and rightousness, and neither do their families.

    So kid, how much do you have in your pocket?


    <QUOTE>I don't know if this is really serious,</QUOTE>

    It's as serious as the people willing to pay for it.


    <QUOTE>but in any case I'd love to know if there's a way to participate.</QUOTE>

    Even if you voluntary, someone else is going to pay to make it happen successfully. The last adjective, "success", is very important. No one wants to put down money on something that will break when used by them.


    <QUOTE>There's this project called Mars One,</QUOTE>

    Which is not a publicly run project, remember. Translation: $$$.


    <QUOTE>but I think that it's closed by now, and that other called Insight, but it's only to send your name.</QUOTE>

    Again, it has to secure the moneys.


    <QUOTE>Do you know if there are realistic projects where they select candidates?</QUOTE>

    You mentioned a few, but consider what you would be willing to do (and for how long) in order to make it successful. No project will pick up someone from Teh Interwebz and strap them on a rocket just for the lulz.

    It all comes down to money. Some people have a lot of it, and can spare some of it to make sure they see something new; think: queen Isabela of Spain (financially backed by taxes) and Christopher Columbus (a private enterpreneur). Someone else would have discovered a new continent and call it by a different name at another time. But no one will be stupid to finance something without a reasonable expectation of success and a realistic estimation of risk.

    So, keep looking at private companies. But remember that they'll only launch those projects as long as there are financial backers.

  • End of the world?

    Best answer: As soon as you see Nibiru AND Planet X mentioned as being the same planet, you know for sure (100%) that it is a hoax, and not even a very good one.

    Best answer: As soon as you see Nibiru AND Planet X mentioned as being the same planet, you know for sure (100%) that it is a hoax, and not even a very good one.

    Nibiru is a fictitious planet, invented for a fiction story (The Twelfth Planet, by Z. Sitchin, 1971). In the story:
    -- it is in orbit around the Sun
    -- it comes near us every 3600 to 3700 years
    -- it never hurts us ("they" need our help for survival)
    -- using data in the story, the next visit cannot be before the year 2085 (and the author did have a reason for that).

    Nibiru only exists in that story (the same way planet Tatooine only exists in Star Wars movies)

    Planet X is a name that was often used. When it is used in the hoax, it is a fake planet, invented for the end-of-the-world of May 2003. In the hoax:
    -- it was a rogue planet (NOT in orbit around the Sun)
    -- Nancy Leider (the inventor of the Planet) claims to have been told by aliens,
    -- it has already killed us all in May 2003,
    -- The movie "2012" (Emmerich) was based a lot on this hoax.

    The pole flips (magnetic poles, that is) were part of that hoax and were used in the movie "2012". The volcanic eruptions were also part of the hoax (and movie) but were stolen from an earlier hoax called the Jupiter Effect (we all died in 1982 during the Great Planetary Alignment). For the Big 2012 Hoax, they added the flip of the real geographical poles in addition to the magnetic poles (making it even less likely).

    For the Big 2012 Hoax (the so-called Mayan Calendar end-of-the-world), the hoaxers combined the two to create an even-more-fake planet that killed us all (again) in December 2012. THAT is the fake planet that keeps coming back to kill us all, year after year.

    Any claim that NASA can hide information is another 100% sure sign of a hoax. There are millions of astronomers, with tens of thousands of them working from very large, professional observatories. Very few of them work for NASA (most are not even American). The only way an astronomer can become famous is to be first to publish important information (as long as it is true information)... and NASA has no control (0%) on what gets published, except perhaps for the 0.01% that work for them.

    The secret underground bunkers were part of the scam for the 2003 version of the hoax, and NASA had nothing to do with it. The hoaxers made money (for real!) by renting out space in such bunkers. So, if you do have too much money, go right ahead and get your own bunker; it will prove useless, but it will be like an extreme camping vacation.

    The 1976 claim, by Sitchin, was made in order to relaunch the sales of his 1971 book. Sitchin never really was an expert in ancient Middle Eastern cultures; he just made that up. Nibiru was an ancient name for the planet we call Jupiter and it is definitely not coming our way. Therefore, the only "true" part of his story is that the word "Nibiru" comes from the Babylonians and Sumerian cultures. The same way Roland Emmerich used ancient Egyptian cultures for the names of the bad guys in Stargate. Has nothing to do with the real Egyptians.

    A "3,600 mile orbit of the Sun" would be completely inside the Sun.

    Best answer: yes, they would. It is inevitable this will happen, assuming we don't destroy ourselves first. and go back to the dark ages, all the way back to hunter gatherer stage.. Tight now, that just as probable as it was during the the late 1950 and early 1960s, but then we had Presidents who were rational and members of Congress who seemed to be more in touch with reality deposit some extremists like McCarthy.. Congress has always had extremists. i didn't understand why my mother wanted to be in the strike zone during the Cuban missile crisis in October, 1962. I was less than 10 years old. 55 years later I agree with her and understand..

    The ONLY reason humans will NOT infect Mars Mars terrestrial life is if humans never make too mars.. Eternity is a VERY VERY VERY LONG TIME.1962

  • Why aren't they sending more space probes to Venus?

    Best answer: It has been struck off the books as a place where life exists.

    Nowadays space exploration revolves around the fanatical obsession with finding a microbe somewhere up in space. As if there are not enough to study right here on Earth. But hence the billions of dollars being poured into Mars missions.

    Cheers!

  • Would “down” and “up” exist in a universe without gravity?

    They say “down” is towards the center of the Earth or the direction gravity is pulling you. So what if the universe had zero gravity and was 5ft in length, 5ft in width, and 20ft in height. Would there be no “down” or “up” in that vertical rectangular universe?

    Best answer: you ARE correct. Space does NOT have an "up or "down." That is true. When YOU are the REFERENCE point, the origin point of YOUR OWN INDIVIDUAL COORDINATE system., left and right are not really interchangeable either. You are doing it again, starting off with a FALSE PREMISE , that is NOT TRUE. Your BRAIN isn't symmetrical. The structure of your brain is different on YOUR right than tn the structure of your brain on YOUR LEFT side. Wheat is "up' and 'down' FOR YOU may be completely DIFFERENT "up' and down' for ANOTHER person who is using THEIR location AND THEMSELVES as as the origin point of THEIR personal coordinate system.


    For the sake of being able TO COMMUNICATE with each other. Up is AWAY from the surface of celestial body" and "down" is TOWARD the surface of celestial body.. BUT space has NO INHERENT "absolute" "up" or "down".

    You ARE CORRECT. Space has NO "up" or "down". You HAVE TO STATE WHAT coordinate system you are using.Yes, coordinate systems ARE abstract, human made concepts. State lines are NOT painted on the ground.on Earth

    YOUR left and right are COMPLETELY DIFFERENT from MY left or right AND up and down.

    Best answer: Not only could earth be hit by Gamma ray bursts from supernovae, or shot out from the poles of quasars (black holes with accretion disks) or shot out from the poles of pulsars, earth is constantly bombarded by gamma radiation from the sun, especially if there is a coronal mass ejection (CME). The earth's magnetic field protects the earth by trapping subatomic particles from the solar wind (and from CMEs from flares) in what is called the Van Allen Radiation Belt. However, gamma radiation is not affected by the earth's magnetic field. Another serious concern is that flipping of the magnetic field of the earth (an event that seems to be happening now, and has happened many times in history). That is, the north and south poles would switch places. This was first observed in a lava flow in the Owens Valley, California, in which the alignment of the then molten rock changed 180 degrees while more lava was flowing. As the poles flip, the magnetic field, at some time, will be gone, and no longer blocking subatomic particles from the sun.

    Lead shielding, or water, or dirt (over your head if you are in a cave) could block gamma radiation. I suppose, that to some extent, an aluminum foil hat would suffice.
