I am not talking about haveing larger solar sails on the space craft. I am talking about placing reflectors around the sun to reflect more sunlight to the solar sail ship. What if it was possible to build a dyson sphere and use half of it to focus half the suns energy onto a solar sail space...

What would happen if our solar system was 1 or 10 or 100 lightyears from a two black hole collision that create these gravity waves we detect in our LIGOs ?

I believe I have an idea on how space/time can curve to create these quantum effects we see in micro-cosmos. Black hole is a kind of makro- cosmic quantum object that is explained my general relativity. A black hole have boundaries like in quantum physics. So the thing is to explain micro-cosmos...

--- Would it be interesting to boost a solar sail spacecraft , so that it accelerate more, by using mega-large mirrors in space to reflect more sunlight to it? MagI -----

--- What if it is possible to develop a reflecting material , that in a parabola, reflect different light frequency just right, so that most light frequencies is then reflected and focused at a specific focus point, far away. Maybe it is possible to adjust this reflecting material (with...

------ Lets play with this idea... So lets say we build a partly dyson sphere, at the mercury orbit distance from the sun and the inside is full of reflectors, that can be aimed to solar sail space ships. That mean that much of the suns light, can be aimed at a spaceship, to give it a...

This can be used to both trips between our planets as to other stars. I understand that there is problems with this idea with technology of today. But we will have artificial intelligens with exponential IQ development, in some years. And we do not know what kind of technology can be...

Yes. So to build these large reflectors they need to be attached to large heavy objects like moons.

Can you explain what you mean?

I got this answer in another forum -------------------- The force exerted by light is F = P/c (where P is the power) for absorption, and 2P/c for perfect reflection. You need P = mgc/2 which, for just 1 kg, is a little less than 1.5 Gigawatts. At the distance of the earth, sun intensity is...

What if you build a Dyson sphear and make large parts of it as a sun reflector to accelerate sun sail spacecrafts .... Interesting ?

Hi. What if we build hundreds of large solar reflectors that can then focus sunlight on a solar sail space craft. How many square miles of sun reflectors would be needed to accelerate a spacecraft at 1 g, on lets say 100 tons to 90% of the speed of light in lets say 3 years ? Regards from...
