Why does a pulsar [fastest rotating objects] can only be seen when its beam is pointing towards Earth?
How can pulsars be seen when their beam is pointing towards earth?
How and why does pulsars emit radio waves only on their poles? An object is projected upwards with a velocity of 100 m/s. It will strike the ground in about? Is there any case where the surface of the earth can be assumed to be a non-inertial frame? Can we see the moon when standing at the North Pole and the South Pole? What if the earth begin to rotate in the opposite direction of its orbit? What would happen if a neutron star collided with Earth? What would happen if a neutron star collides with earth? How do flat earthers explain the rotation of planets as seen through telescopes? Why earths axis is tilting? Why can't we see the other side of the moon, and what is on the other side? What will happen if the earth starts rotating vertically on its axis? If the sun is pulling us downward when we look at it from earth, is that direction down? How do I find the exterior angles of a nonagon? How does the top of a commercial solar tower not melt when all the mirrors are pointing light at it? Is there a place on Earth where the setting sun and the rising moon can be seen at opposite sides of the sky? Why is the Earth not attracted towards the sun when it’s at its perihelion? How is Pulsar 220? Can we observe planets surfaces and subsurfaces using radio/micro/IR waves passively? How are poles of the earth fixed? How do red dot sights/holographic sights work? Can you see the light if it's turned on and aimed at you? How does torsion occur on the end of a beam? How can we provide a hidden beam in slabs? What happen when earth is near to the sun and how? Since few gamma and cosmic rays can pass through our atmosphere, can we image Earth with them and using their penetration image its subsurface? What happens when the earth rotates to the opposite direction? How do we observe planets with radio telescopes? Why can't we see the far side of the Moon and why doesn't the Moon spin on its axis? What would happen to Earth's trajectory if we attached an unbreakable rope from the North Pole on Earth to an arbitrary anchor point on the moon? What is the movement of earth around its axis? What would it look like through a telescope if all the planets aligned?
