In a remarkable achievement, China has successfully collected samples from the far side of the moon, marking a significant milestone in space exploration. The Chang'e-6 mission, launched on May 3, touched down in the Apollo crater within the vast South Pole-Aitken basin on June 1. During its brief but productive stay, the spacecraft gathered approximately 2 kilograms of lunar material using a scoop and drill. The samples, now stored in an ascent vehicle, are expected to return to Earth on June 25, landing in Inner Mongolia. This historic achievement not only demonstrates China's space program prowess but also provides scientists with a unique opportunity to unravel the mysteries of the moon's formation and evolution. Achievements: - *First-ever samples from the far side*: Chang'e-6 successfully collects lunar material from the moon's less-explored hemisphere. - *Second successful farside landing*: China builds on its 2019 achievement with...
R. Rafini and J. Weeler, 2 scientists on 1967, represented the space-time near black hole in a diagram
Imagine an Astronomer and his friend are going to have an experiment, astronomer wants to go through black hole and his friend stay away from black hole and take signals astronomer sends. Before astronomer arrives to the Schwarzschild’s radius, he sends signals to his friend and his friend receive them without any problem (points A and B in Diagram 1) and his friend is traveling from past to the future in the space shuttle (line O in Diagram 1) But when astronomer enters to the Schwarzschild’s sphere, no signal will be delivered by his friend .
The space time near black hole. Astronomer approaches to the black hole (point A to F) and sends signals to his friend who’s moving on line O in the Space Shuttle and receives astronomer’s signals. Also when astronomer gets out of the white hole in past space-time on point X, he can be able to send signals to his friend and his friend can deliver them without any problem.
there are 4 space-times; first one is our universe’s space-time. The second one is the future space-time. Third one is like a mirror of our universe; we have no idea about this universe because it’s unreachable except one condition.
We can be able to reach that universe through Einstein-Rosen Bridge or in other word, worm hole. Although, worm hole just opens in a short period of time. During this period, we need to go through it with a velocity more than the velocity of light
Worm holes are bridges located between black holes and white holes and the parameters of space time inside and outside the worm hole are very different; imagine we have a timer inside and outside the worm hole, the difference between our measurements is shown in Figure 5. It’s similar to the relativistic time dilation in special relativity but there is a difference which is the object travels back in time .
Fourth one is the past space-time. Black holes have convergence and everything around them will fall into them by their strong gravitational field. But in this space- time, in contrast to black holes, we have divergence for objects which have already been fallen into black hole and they are called “White Hole”. As you see in Diagram 1, the astronomer that gets out of white hole, can send signals from point X to his friend without any problem and he will deliver it . Arriving at a speculation does time exist in a black hole??
