can a rocket travel at the speed of light插图

NASA just announced that their new rocket engine could travel at99 percentthe speed of light. If this is true, a new era of space travel has begun. The speed of light is primarily used as the most preferred unit to measure distance in space.

Can a rocket travel at 99% the speed of light?

NASA just announced that their new rocket engine could travel at 99 percent the speed of light. If this is true, a new era of space travel has begun. The speed of light is primarily used as the most preferred unit to measure distance in space.

How do rockets travel so fast?

Rockets burn huge amounts of fuel very quickly to reach escape velocity of at least 25,000 mph (7 miles per second or 40,000 km/h), which is how fast something needs to go to break away from the pull of Earth’s gravity.Second, escape velocity is really about energy, not velocity or speed.

Could a photon rocket open up the universe to humans?

Haug’s paper outlines the mathematics involved in developing a rocket that could take us to speeds just shy of light speed by taking cues from projects that utilize photons as driving mechanisms. Such a photon rocket could make the idea of deep space travel far more attainable, and could open up the universe to the human race.

What is the escape velocity of a rocket in mph?

Rockets burn huge amounts of fuel very quickly to reach escape velocity of at least 25,000 mph (7 miles per second or 40,000 km/h), which is how fast something needs to go to break away from the pull of Earth’s gravity.Second, escape velocity is really about energy, not velocity or speed. How long does it take for a rocket to get to space?

What are the two components of relativistic speed?

1) Electromagnetic Fields. Most of the processes that accelerate particles to relativistic speeds work with electromagnetic fields — the same force that keeps magnets on your fridge. The two components, electric and magnetic fields, like two sides of the same coin, work together to whisk particles at relativistic speeds throughout the universe.

Why do electromagnetic fields accelerate particles?

In essence, electromagnetic fields accelerate charged particles because the particles feel a force in an electromagnetic field that pushes them along, similar to how gravity pulls at objects with mass. In the right conditions, electromagnetic fields can accelerate particles at near-light-speed. On Earth, electric fields are often specifically …

What is the purpose of NASA’s Magnetospheric Multiscale Spacecraft?

NASA’s Magnetospheric Multiscale spacecraft were designed and built to focus on understanding all aspects of magnetic reconnection. Using four identical spacecraft, the mission flies around Earth to catch magnetic reconnection in action.

How do particles get energy?

When electromagnetic waves collide, their fields can become compressed. Charged particles bouncing back and forth between the waves can gain energy similar to a ball bouncing between two merging walls.

How does an electric field work?

On Earth, electric fields are often specifically harnessed on smaller scales to speed up particles in laboratories. Particle accelerators, like the Large Hadron Collider and Fermilab, use pulsed electromagnetic fields to accelerate charged particles up to 99.99999896% the speed of light. At these speeds, the particles can be smashed together …

Why do we see explosions in space?

These explosions are the result of twisted magnetic fields that snap and realign, shooting particles across space.

How fast do particles travel in space?

The theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that’s immensely difficult …

What is the most efficient self propelled rocket?

The most efficient theoretical self propelled rocket would use total conversion of mass to energy (if that’s possible) to direct electromagnetic waves as thrust (light, microwaves, or whatever). In science fiction this is often referred to as a photon drive.

What is the equation for liner velocity?

Anyway I then looked at liner velocity equations v=v1 + adt… So let’s just use some numbers v= ? v1= 0 a= 9.8 and dt = infinite. After I look at this equation it made me think he was right.

How does adding mass affect top speed?

We have a chemical rocket, we add more fuel to it. This increases the mass so decreases the rate of acceleration the engines can give. However if we just keep adding mass there wont be a point where adding the mass gives no overall effect to top speed.

Can you increase the velocity of a rocket with unlimited fuel?

It’s velocity could reach like 99% the speed of light" I argued that it was not possible , as it approached the speed of light it’s mass would increase and you would require more energy to increase the velocity. I realize the question is flawed already with the fuel at an inflate amount.

Can a chemical rocket accelerate?

Well, no. A chemical rocket the size of the earth would need to accelerate it’s own mass. Chemical rockets of any size won’t get anywhere near ‘c’.

Can a rocket reach 99% of the speed of light?

You argued that it’s impossible to reach 99% the speed of light. This is incorrect. It’s not possible for a rocket to reach 100% the speed of light, but it IS possible for it to reach 99%. There is a HUGE distinction there.#N#Even 99.999999999999999999% is possible (theoretically).#N#If you were measuring the speed of this magical rocket from earth, it need not stop accelerating. However, it’s acceleration would slow down more and more as it approached the speed of light…but it never need reach 0. It’s kind of like walking across a room by halving the distance to the wall. You will never reach the wall, but you can keep getting closer.#N#As ryan_m_b mentioned, from the astronauts’ perspective the rocket can keep a constant acceleration. The discrepancy is due to relativity.

Is it possible to have infinite 9s?

If you mean infinitely many 9’s, then it’s not possible because 0.9999999…… (infinite 9’s) = 1.

What is the purpose of helical engines?

However, the real purpose of the so-called “helical engine” would be to travel to distant stars far quicker than any existing tech, according to NASA engineer Dr David Burns. Dr Burns, from NASA’s Marshall Space Flight Centre in Alabama, unveiled the idea in a head-spinning paper posted to NASA’s website. “This in-space engine could be used …

How to close a modal window?

This is a modal window. This modal can be closed by pressing the Escape key or activating the close button.

What is the law of motion that describes a ring inside a box?

When the ring is sprung in one direction, the box recoils in the other, as is described by Newton’s laws of motion: Every action must have an equal and opposite reaction.

What is the EM drive?

They include the EM drive, a machine that could theoretically generate rocket thrust using rays of light. The idea was later proved impossible.

How fast can a rocket go to Mars?

Travelling at such speeds, the theoretical machine could carry astronauts to Mars in less than 13 minutes, or to the Moon in just over a second.

Why is Dr Burns mad idea revolutionary?

Dr Burns’ mad idea is revolutionary because it does away with rocket fuel altogether.

What rover took pictures of the Red Planet?

NASA’s Curiosity rover took such remarkable images from the Red Planet, it left members of the mission team “stunned”.

How fast do rockets go in mph?

How fast does a rocket have to travel to get into space? This really depends on what you mean by “into space.” If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour.

How fast could a spaceship travel?

At that point, the spacecraft will be speeding along at a whopping 430,000 mph (692,000 km/h).

How do rockets travel so fast?

Will we ever travel faster than light?

For this reason, no normal object can travel as fast or faster than the speed of light.

Can humans survive light speed?

No, it is not possible for a human to survive travelling at the speed of light. Others have pointed out that it’s impossible to reach the speed of light, so they’re talking about the limits as you approach the speed of light. But at the speed of light, you experience singularity-like conditions.

Can NASA travel light years?

Eventually, the Voyagers will pass other stars. In about 40,000 years, Voyager 1 will drift within 1.6 light-years (9.3 trillion miles) of AC+79 3888, a star in the constellation of Camelopardalis.NASA’s New Horizons spacecraft travels at 36,373 miles per hour (58,536 km/h).

What fuel do rockets use?

The petroleum used as rocket fuel is a type of highly refined kerosene, called RP-1 in the United States. Petroleum fuels are usually used in combination with liquid oxygen as the oxidizer.
