400 Octillion Joules. (400,000,000,000,000,000,000,000,000,000)
It's not really a fair question, however.
The Death Star, as depicted in the Star Wars Movies, is grossly overpowered for its purpose. It would take a tiny fraction of that energy to simply vaporize the surface and wipe out all life.
Okay, I admit I did not actually calculate the energy required to vaporize a planet. I simply assumed that the energy output of a Sun like star would be sufficient if it were all turned on puny little Alderaan (or Earth).
The Sun outputs 400 Octillion Joules / second.
Because of gravity. Only gravity can pull large clouds together with enough force to overcome gas pressure.
Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.
The answer is simple: gravity.
Gravity is a friend of a star as it is the force that holds the star together, enabling it to maintain its shape and generate energy through nuclear fusion. However, gravity can also be an enemy of a star when the star runs out of fuel, causing it to collapse under its own gravity and potentially undergo a violent explosion, like a supernova.
Any type of gas can do that. The only condition is that there be a sufficient amount of gas - otherwise, the gravity won't be able to overcome the pressure of the gas.
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
Some ways to overcome gravity include using a rocket propulsion system to generate enough thrust to escape Earth's gravity, utilizing advanced technology like electromagnetic propulsion systems, or harnessing anti-gravity technology if it becomes possible in the future.
No, it is not possible to fly with magnets. Magnets do not have the ability to generate enough lift to overcome gravity and allow for sustained flight.
A car must overcome several forces to move, including friction (from the tires on the road), air resistance, and gravity. Additionally, the engine must generate enough power to overcome these forces and propel the car forward.
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.
no
Lift generated by the wings of a plane counteracts the force of gravity pulling it down, allowing the plane to stay in the air. For a plane to achieve lift greater than gravity, it must generate enough thrust through its engines to maintain forward motion and generate sufficient lift from its wings to overcome the force of gravity.
it needs to overcome the gravity of the earth lol
The first rocket had to overcome Earth's gravity to reach space. It needed to generate enough thrust to propel itself upward and break free from the pull of gravity, allowing it to reach the necessary speed to enter into Earth's orbit.
Go to space.
To reach outer space, rockets must escape the force of gravity. Gravity is the force that pulls objects towards the center of a mass, such as the Earth. Rockets need to generate enough thrust to overcome Earth's gravity and reach escape velocity to enter outer space.
