they have to pass some forces in the earths atmosphere
They have to overcome the force of gravity, lifting the rocket and all of the fuel to an escape orbit.
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
IT took a huge leap as military and business industries combined their efforts in the early 1900s. Together they were a major force in IT research and development.
Near, far, and huge pointers are different types of pointers used to reconcile the different addressing models of the Intel 8086/8088 class processors, running in a 16-bit operating system such as Windows 3.x, as well as any of the newer incarnations running in real mode or virtual 8086 mode.A near pointer can address something within one 64Kb memory segment, containing only an offset, and it takes two bytes. The segment is implied by context, and is usually the data segment, selected for the addressing model.A far pointer can address anything in the 1Mb memory1, containing both a segment and an offset, and it takes four bytes.A huge pointer is a normalised far pointer, which means its offset part is always between 00H and 0FH.In 32-bit mode a pointer can address anything in 4Gb memory, containing a flat 32-bit offset, and it takes four bytes. (In this mode segments have no significance.) It only works, however, when there is support for it, such as the WIN32 extension of Windows 3.x.---------------------------------------------------------------------------------------1In the 80286 or higher, running in protected mode, in OS/2, the segment portion of the pointer is actually a descriptor selector, so 1Mb addressibility depends on the operating system environment.far huge near pointer is an oxymoron. far points to memory outside of the normal address space. near points to memory within the normal address space, is the default, and usually is not needed. I've never seen huge before. What is the target architecture?Near, far, and huge pointers are a construct (usually) in the Win16 environment running on an 8086/8088 or later in real mode, such as Visual C/C++ 1.52. In this environment, near pointers are 16 bits, and far and huge pointers are 32 bits.
Yes.
innumerous uses but at a huge cost
Yes, nukes(nuclear weapons) can travel up into space to destroy asteroids and huge flying rocks.
No, because sound cannot travel in outer space.
Rockets are needed to lift payloads into space, whether it's to launch a satellite into an orbit around earth or to send a probe out into our solar system and beyond. A lot of speed is required to be able to escape the gravity of the earth. This is provided by the rocket and the huge amount of fuel.
By using the law of action and reaction. The rockets that launch spacecraft expel huge amounts of hot gas from burning fuel out of their exhausts, and this pushes the rocket (vehicle) upward in a rapid acceleration. This is necessary to overcome the force of gravity that pulls down on everyone and everything on the Earth. When the spacecraft is moving fast enough (escape velocity), it is able to enter an orbit around the Earth. From orbit, spacecraft can use smaller rockets to leave Earth entirely, and travel to the Moon or to other planets. The limit to this is that you need to use lots of energy to get to space, and even more to go anywhere else. All of the fuel has to lift its own weight as well as the craft (payload), so this takes very large rockets and huge amounts of fuel.
Because, to accelerate time, you need either linear acceleration or gravity. So our best bets would be HUGE rockets or to orbit black holes
rockets have more disadvantages than advantages rockets are extremely inefficient they consume enormous amounts of fuel, and most still use liquid propellant which is hard to find in space, they do however have a huge thrust to weight ratio
Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit.

When astronauts travelled to the Moon, another smaller rocket pushed the Apollo spacecraft out of orbit, and carried it to the gravitational field of the Moon. Another rocket firing pushed the craft back to Earth. Unmanned space probes have travelled to even farther distances from Earth, including the outer planets Uranus and Neptune. Most of the travel is coasting, because there is practically no matter in space to slow a spacecraft down.
Two huge solid fuel rockets, and Three big rocket motors burning fuel from an external tank big as a grain silo at a ferocious rate.
There is a huge rocket engine test facility in Mississippi. http://en.wikipedia.org/wiki/John_C._Stennis_Space_Center
One problem with space travel is that space is huge. How huge? Unimaginably huge. It is Billions of Billions of Billions of miles across. Our Earth is only 9,000 miles across. So, it'll take a long time to go anywhere. Also, if you go near something with gravity, you'll be pulled in.Either a planet, or a star. Anyway, you'll need tons of oxygen to keep you alive for who knows how many years in space. But that is now. Who knows, maybe we'll find something to make us travel anywhere in a blink of an eye?
The British began using rockets as weapons in the late 1700's, but they were inaccurate in their aim. The main purpose for the Brit's using rockets was to reduce enemy morale. The Tippoo Sultan of Mysore, India famously used 1000's of rockets in defending Seringapatam (a huge well defended fortress) against the British in 1799. Editor's Note: The rockets were used by the Brits to siege ports. Isaac Newton was the developer of the rockets they used. Another fellow improved the rockets adding the fins so they would spin into the direction they wanted to the rockets to go. This technology is still used today. Rockets are still used for "shock and awe" or to confuse the enemy. We use rockets now primarily to send satellites into outer space.
