Is a dark star a real thing?

Scientists think that out of this rich environment, a new breed of star was born: dark stars. Dark stars are somewhat of a misnomer — they're not actually dark. In fact, they're likely some of the biggest and brightest stars in our universe. Yet no one has ever seen one.

Is the SR-72 real?

The SR-72 doesn't really exist, but engineers at Lockheed Martin had a hand in its development. The company's famous Skunk Works division developed the SR-72, as well as the real SR-71.

What is a dark star called?

Astronomy. Dark star (Newtonian mechanics), a star that has a gravitational pull strong enough to trap light under Newtonian gravity. Dark star (dark matter), a star heated by annihilation of dark matter particles within it. Dark-energy star, an object composed of dark energy that outwardly resembles a black hole.

Is Top Gun: Maverick realistic?

A Madison-based pilot enjoyed the entertainment of “Top Gun: Maverick” and says parts of the film are accurate, but not all of it. MADISON, Wis. (WMTV) - A Madison-based pilot enjoyed the entertainment of “Top Gun: Maverick” and says parts of the film are accurate, but not all of it.

The Mysterious SR-72 Darkstar Could Enter Service in the 2030s

Does MiG 28 exist?

MiG-28: a fictional aircraft flown by the antagonist in the 1986 film Top Gun. The real aircraft used to portray the MiG-28 was a Northrop F-5.

Can anything go Mach 10?

On November 16, 2004, NASA made history by launching the X-43A, the first-ever air-breathing hypersonic vehicle, into the atmosphere, achieving Mach 10 speed. The X-43A separated from its booster and accelerated on scramjet power at nearly ten times the speed of sound (7000 MPH) at roughly 110,000 feet.

How big is a dark star?

Under this model, a dark star is predicted to be an enormous cloud of molecular hydrogen and helium ranging between 4 and 2,000 astronomical units in diameter and with a surface temperature and luminosity low enough that the emitted radiation would be invisible to the naked eye.

Is a dark star a black hole?

As it turns out, any star greater than 3 solar masses must eventually form such a "dark star" after thermonuclear reactions have ceased, since no known source of pressure can support it. These objects are called "black holes" and this term was first coined by the physicist John Wheeler.

Will we ever get to another star?

The nearest star is four light years away. That means that light, traveling at 300,000 kilometers per second would still need FOUR YEARS to reach the nearest star. The fastest spacecraft ever launched by humans would need tens of thousands of years to make that trip.

Is the Aurora plane real?

Aurora was a rumored mid-1980s American reconnaissance aircraft. There is no substantial evidence that it was ever built or flown and it has been termed a myth.

How long would it take to go around the world at Mach 20?

Mach 20. If a plane flew at Mach 20 without stopping to refuel, it would take 1 to 2 hours to circumnavigate the earth. Theoretically, if a plane flew on Mach 27 without stopping to refuel, it would only take it 1 hour and 10 minutes to circumnavigate the earth.

How long would it take to go around the world at Mach 6?

At this speed, the SR-72 can cross the Atlantic (or Europe or China or…) in about an hour — or circumnavigate the planet in six hours. At an operational altitude of around 80,000 feet (24,300 meters) and Mach 6, the SR-72 will be almost impossible to shoot down.

What does a dark star look like?

Dark stars don't just behave differently than normal stars. They also look different. Because dark stars don't rely on core fusion to stave off gravitational collapse, they're not extremely compressed like normal stars. Instead, dark stars are likely giant, puffy clouds that shine extremely bright.

What would happen if you survived a black hole?

Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home. Aside from this, your body would be stretched and destroyed by the warping of space and the amount of radiation surrounding the event horizon.

What is inside a white hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

What is inside a black hole?

The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.

How hot is a black star?

Surface temperature is low, below 600K, even as low as 5 degrees kelvin. It emits no visible light, only a very faint infrared radiation, So, it cannot support light or heat an orbiting planet. Because of its small size and high mass, its density is very high, over 1 million times that of the Sun.

Who found dark stars?

During 1783 geologist John Michell wrote a letter to Henry Cavendish outlining the expected properties of dark stars, published by The Royal Society in their 1784 volume.

Can stars be frozen?

A white dwarf star actually freezes first in the center, where the density is highest, to become a solid mixture of carbon and oxygen -- so packed that the elements form a crystal-like arrangement. Then the rest of the star gradually freezes from the inside out until the whole star becomes frozen.

What happens to a dark star?

Thanks to Einstein's theory of general relativity, which describes how matter warps space-time, we know that some massive stars can collapse in on themselves to such a degree that they just keep collapsing, shrinking down into an infinitely tiny point — a singularity.

Why do planes not fly over the Pacific Ocean?

Most flights are planned to minimize the time spent over bodies of water, since storms are more likely to occur over water than land. The weather over the Pacific Ocean is often turbulent, and there are many thunderstorms in parts of the Pacific, so it's not a safe environment to fly a plane.

What is 1mach?

A Mach number is the ratio of an object's speed in a given medium to the speed of sound in that medium. Mach 1, then, is the speed of sound, around 761 mph at sea level on a standard day. The term is also used as a metaphor for high speeds more generally.
