Einstein’s light cone and five-dimensional spacetime.

“Light cone in 2D space plus a time dimension, more commonly referred to as ‘space time’” (Wikipedia) The light cone introduces the model. That time focuses information on the hypersurface of the present. But why can't we see into the past or future? Entropy is introduced as the reason for. Why can't we see the future? Or to the past. This means that entropy scatters information into such a small mosaic and twists it. That information exists. But. We cannot collect it into a form. That. We can use it. Term spacetime, or. Space time. Means the space and time. “In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events occur.” (Wikipedia, spacetime) There is a connection between time and space, an...

Supermassive black holes from the universe's dawn.

“An AI-generated visualization of a distant galaxy, containing, besides dust, gas, and young stars, three massive, active black holes (black spheres, not to scale) with bright accretion disks. Other distant galaxies are shown in the background. And. A few stars in the foreground.

Reseachers found three supermassive black holes in one galaxy. And the famous “little red dots” from the dawn of time. They are so-called black hole stars. Or at least some of them are. Those objects should tell us about the history of the young universe. And. Those distant objects. Tell us about gravitational interaction behavior over very long distances. We know that gravitational waves have a speed. Gravitational waves travel at the speed of light. This means. That gr...

A superkilonova, which has never been seen before, may be spotted.

These blasts scatter heavy elements such as carbon and iron into space, helping enrich the universe. A different and far rarer kind of cosmic explosion, known as a kilonova, happens when two neutron stars collide. Neutron stars are the dense remnants of dead stars, and when they merge, they can create even heavier elements, including gold and uranium. Materials like these later become part of new stars, planets, and other cosmic structures."
