    Undergrad How to save petrol in a Petrol Engine

    Like Gas Engine can we use Petrol Engine working as Gas Engine? I mean instead injecting petrol directly into engine can we inject vapours of petrol into engine using vacuum pump? Can we save petrol in this way without using stroke oil?

    High School Could a Black Hole Cause a Sunrise in the West?

    Please forget what I believe. I simply want to know probability of sunrise in the west. May be some other thing would cause this astronomical phenomenon - An optical illusion would be created by ?

    High School Could a Black Hole Cause a Sunrise in the West?

    It means if it does happened then different phenomenons would be observed at different places on Earth at the same time. Solar eclipse (night), sunrise in the west, sunset in the east etc. due to constant motion of black hole. Am I right in guessing?

    The speed of moving black hole should be very high as compared to rotational speed of our earth. The black hole would bend the eastern rays of the sun to (derived) western rays of the sun thereby creating an illusion of sunrise in the west.

    High School Could a Black Hole Cause a Sunrise in the West?

    Dear All Concerns Black Hole is formed at the end of life of a big star. The mass of such star should be equal to 5-10 solar masses. But I am imaging very small moving black hole coming to our solar system and passing between our Earth planet and the sun thereby creating solar eclipse of unique...

    High School Black Hole Gravitational Lens: Bending Light & Mass

    Thanks for your information. I am interested in deflection pattern of light by black hole. Is there any difference in the deflection angle of light by black hole if : r is the perpendicular distance from the black hole & r is the angular distance from the black hole

    High School Black Hole Gravitational Lens: Bending Light & Mass

    https://en.wikipedia.org/wiki/Gravitational_lens I want to know about bending light property of a black hole. The bending angle formula does not tell that r is perpendicular distance to light. Does a black hole having mass M has different bending power than the body having the same mass M...
