I would like to understand , how a beam laser changes its trajectory near of a supermassive body? Is there any relation with Einstein's equivalence equation between mass and energy?
Naty1 said:Another way to think about the curving of the laser light is to note that because it's already moving at "c" in a local frame, it can't accelerate in the direction of velocity:it can't go faster than c. But a gravitational field CAN accelerate the light (change direction but not speed) at right angles to the direction of velocity; hence it can be curved by a force perpendicular to the direction of motion.

So I assume that when a laser beam is aimed toward the center of gravity ILO horizontally across that field it accelerates 'in the direction of velocity'.

...yes...it slows...Sounds like rubbish to me; light curves towards the direction in which it travels SLOWER
When a laser travels near a supermassive body, it is affected by the strong gravitational pull of the body. This causes the path of the laser to curve, similar to how a planet's orbit around a star is affected by gravity. The laser will also experience a time dilation effect, where time appears to slow down for the laser as it moves closer to the supermassive body.
Yes, lasers can be used to study supermassive bodies by measuring the changes in the laser's path and time dilation as it travels near the body. This can provide valuable information about the mass and gravitational pull of the supermassive body, as well as its effects on space-time.
While the path of a laser traveling near a supermassive body can be affected by its strong gravitational pull, it can still be predicted using mathematical equations and models. However, slight variations in the body's mass and position may cause small deviations in the laser's path.
If a laser gets too close to a supermassive body, it may be pulled into an orbit around the body or even fall into it. This is due to the enormous gravitational pull of the body, which increases as the laser gets closer. In extreme cases, the laser may be completely absorbed by the body.
Yes, lasers can be used to detect supermassive bodies that are not visible by measuring the changes in the laser's path and time dilation as it travels near the body. This can help scientists identify the presence and characteristics of these invisible bodies in space.
