• A scientist suggested that NASA build a unmanned space station on the Mercury and locate this station in a crater at its north pole.?

    Best answer: 1- Going to Mercury requires almost as much energy as going to Jupiter (unlike going to Jupiter, where you speed out towards the outside of the solar system, going to Mercury requires losing a lot of energy to fall to the lower orbit; in space, accelerating and decelerating is the same, it is just a matter of direction)
    2- Reaching Mercury's pole means realigning the orbit from a equatorial to a polar orbit; that is also a lot of energy
    3- While in orbit (and while approaching) any ship is exposed to a between 5 to 10 times as much solar energy as we get on Earth. While this would work great for solar panels, this means the ship (and crew) would tend to be cooked quite a lot
    4- At the pole, due to the lack of atmosphere, in the shade, the temperature is around 110 K. That is -163 C. Or -262 F if you are still stuck with the antiquated system of units.
    5- The absence of atmosphere means that landing on Mercury has to be done purely with retro rocket, as opposed to parachute with ablative of refractory heat shields like on space capsule or shuttle. This means you need about as much fuel to land from orbit as is required to lift off from the surface

    So I was at a bonfire party in rural indiana last weekend (June 16) with a good 10-20 of people. Once it became dark, we all pretty much quit staring at the fire and started gazing up at the stars. Around 1 am, while listening to music on a phone via the stereo, a spectacularly bright comet went streaking directly over us. It burned a bright magnificent green, causing the trail of smoke to be clearly visible going across the entire sky. In the 2 or 3 sec this took place, the radio went completely static, quickly returning to normal once it had gone! So what element in its composition would cause this interruption? Why would the stereo even go static considering the music was coming from a phone via aux cord and not a tuned in radio signal? Thanks for the help!

  • Why haven t we traveled any further than the moon by now? It s now 2018 don t we have the technology for this yet?

    Best answer: It's not about technology. Just getting anybody to, say, Mars, is not the problem. After all, unmanned probes have been to have a look at all the planets and several comets. The problem is the difficulty of sending actual people.

    People need food, air, the ability to cope with being cooped up in a small spacecraft for months or years, and gravity to prevent their bones and muscles wasting away. So they need total recycling including growing their own food, the mental stability for it, and lots of exercise to keep them fit - which is why ISS astronauts are required to exercise on treadmills and other equipment for 2 hours a day, and even so, they still tend to feel a bit weak when they first get back down to Earth.

    This is all being researched on the ISS and they haven't yet got as far as being able to do all this. The ISS is still reliant on food and clothes being sent up from the ground. How do you wash clothes in space when the water just floats? So they don't even try that, they just wear clothes for a week and throw them out, so they always need more new clothes sent up.

    Furthermore, how will they survive the journey without dying of cancer caused by radiation? Stay close to the Earth and you're protected by the Earth's magnetic field, or for just a few days further away it'll be OK as it was for the Apollo missions. But otherwise, it's a blizzard of cosmic radiation out there, mostly of charged particles emitted by the Sun, and it would be like living in continual nuclear fallout. Unless you can develop a spaceship that includes the necessary shielding and isn't immensely heavy, there is no way anyone is going anywhere.

  • Can the Space structure of the Universe be considered as a real mass as opposed to imaginary space time theory?

    Best answer: What does that question actually mean? Space is more than the mass that is in it. Mass isn't the structure, it collects into structures. You can consider how the mass behaves, and when you note that mass behaves by forming structure, then the curious mind asks the obvious question "Why?". And... show more

You can consider how the mass behaves, and when you note that mass behaves by forming structure, then the curious mind asks the obvious question "Why?".

    And really, all "theory" is imaginary, a mental model of what we observe reality to do, a way that allows us to understand what is occurring.

  • Isn't time the result of compressed space,does that mean time changes are proportional to space density changes?

    Best answer: No, time is the NOT the result of compressing anything. Time is a temporal dimension, NOT a spatial dimension.

    Best answer: No, time is the NOT the result of compressing anything.

    Time is a temporal dimension, NOT a spatial dimension.

    Time exists even if there is no mass within very small volume of space like a cubic centimeter. Even if there is one proton or electron or neutron with mass in that cubic centimeter volume of space. TIME still exists within that cubic centimeter of space and the electron, proton or neutron does NOT have to compressed. If the the electron, proton or neutron is MOVING THROUGH that cubic centimeter of space. TIME EXISTS IN that cubic centimeter of space. that cubic centimeter of space is NOT REQUIRED to have ANY mass in it for TIME to exist IN that cubic centimeter of space.

    Time is an integral component of the Universe. No matter HOW time is MEASURED by human beings is IRRELEVANT. Time existed long before the species homo sapiens evolved, and Homo sapiens is evolving RIGHT NOW. so is the rest of the Universe, whether human beings exist or N OT..

    Time is NOT compressed mass or compressed ANYTHING. Yes, the PRESENCE of mass DOES determine HOW time is measured RELATIVE TO THAT MASS, but Time EXISTS separate FROM mass.Time does NOT REQUIRE compression of anything to exist. Time is NOT a spatial dimension.

    The Alcubierre drive, also known as Star Trek's Warp drive is the theoretical drive that makes space smaller in front of space ship and expand it at the back. In the original design the Alcubierre drive needed a lot of energy. But even if we somehow were able to generate so much energy, which kind of mechanism makes this energy collapse space in front of a space ship? The only thing I know that can fold space very well are neutron stars and black holes. Is the idea with the Alcubierre drive to form a tiny example of either one of these in front of the ship and before the ship crosses the Event Horizon the Black Hole evaporated due to Hawking Radiation?
