# Sun Rise Laser Cannon Aiming - Unraveling the Mystery

• gunblaze
In summary, determining the exact spot to hit the sun dead center with a laser cannon would require precise calculations and considerations of various factors, such as time delay, atmospheric refraction, aberration, and general relativity effects. It would also require accurate data and equations, making it a difficult and impractical task.

ok...

So, we see the sun everyday, right?

So let's say you are standing on one point of the Earth looking at the sun rise... At where must you point a laser cannon in order to hit the sun dead centre? and why?

I won't do the calculation, but several effects come to mind:

1) Time delay - It takes about 8.5 minutes for light to reach the sun from here, so you'd have to take the sun's motion during that time into account.
2) Atmospheric refraction - The sun's actual position is shifted from the apparent one by the bending of its light in the atmosphere. Although the laser beam would be bent as well, this bending is wavelength-dependent, so the shift wouldn't be the same. Also, the Earth would be at a different point in its orbit when the laser's light was bent, so the path would be slightly different.
3) Aberration - The sun's apparent position is shifted due to the Earth's motion. This is the same effect that has to be considered when measuring stellar parallaxes.
4) GR effects - The light beam will follow a geodesic in spacetime, not a straight path in space. The difference should be very small, but non-zero.

In other words, you couldn't just point the beam at the center. I think that would get you pretty close, though.

ok...thx spaceTiger
but is there a way to find the exact spot eg:how much cm/metres to the centre of the sun?

Yes there is; for starters you need an accurate ephemeris, your own position on the Earth (accurately), the wavelength of the laser (in the laser cannon, and probably its intensity), all the right equations, and a means of doing the calculations.

In addition to the effects SpaceTiger mentioned, you may also need to consider how the path of the light will be affected traversing the Sun' corona, chromosphere, and upper photosphere. There's also the question of what "the sun['s] dead centre" actually is!

You could theoretically perform such a calculation, but I wouldn't recommend it unless you had a really good reason. You could define an exact center of mass (in the classical limit), but again, this would be really messy.

## 1. How does the Sun Rise Laser Cannon work?

The Sun Rise Laser Cannon works by using a series of mirrors and lenses to focus and amplify a powerful laser beam. This beam is then directed towards a specific target with the help of precise aiming mechanisms.

## 2. What makes the Sun Rise Laser Cannon different from other laser weapons?

The Sun Rise Laser Cannon is unique due to its ability to accurately aim and target moving objects, such as missiles or aircraft. This is made possible by its advanced tracking and targeting systems.

## 3. How does the Sun Rise Laser Cannon's aiming system work?

The aiming system of the Sun Rise Laser Cannon uses a combination of sensors, cameras, and advanced computer algorithms to track and predict the movement of its target. This information is then used to adjust the positioning of the laser beam for precise aiming.

## 4. What are the potential applications of the Sun Rise Laser Cannon?

The Sun Rise Laser Cannon has a wide range of potential applications, including military defense, space exploration, and industrial cutting and welding. It can also be used for scientific research and experimentation.

## 5. How is the Sun Rise Laser Cannon powered?

The Sun Rise Laser Cannon is typically powered by a combination of electricity and chemical energy. It may also use solar panels to harness the energy of the sun. The specific power source may vary depending on the intended use of the weapon.
