What is the name of the three dimensional figure made up of six faces that are all rectangles?

A solid (3-dimensional) object which has six faces that are rectangles. It has the same cross-section along a length, which makes it a prism. It is also a “cuboid”.

Why is string theory wrong?

An increasing number of physicists are skeptical that string theory can unite the fundamental forces of nature. And some physicists now view strings as a failed theory because it doesn’t make useful predictions about the universe.

Is time actually an illusion?

The concept of time is simply an illusion made up of human memories, everything that has ever been and ever will be is happening RIGHT NOW. Most people do not even consider the concept of time but there is nothing in the laws of physics to state that it should move in the forward direction that we know.

Can a time machine be invented?

Time travel may soon be possible, according to an astrophysicist who believes he’s worked out a way to build a time machine. Professor Ron Mallett from the University of Connecticut in the US claims to have written a scientific equation that could be used to create a device that takes people back in time.

Does time exist inside a black hole?

For outside observers, a black hole is one solidary element, and there is no proper time inside the black hole, but there is only the observed coordinate time according to our spacetime coordinates.

Can a time machine be built?

Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality.

Are white holes real in space?

Why white holes don’t exist While general relativity describes white holes in theory, no one knows how one might actually form. A black hole cordons off its bit of space when a star collapses into a tiny volume, but playing this video backwards doesn’t make physical sense.

What’s inside a black hole?

HOST PADI BOYD: While they may seem like a hole in the sky because they don’t produce light, a black hole is not empty, It’s actually a lot of matter condensed into a single point. This point is known as a singularity.

What happens if you fall into a black hole?

What happens if you fall into a black hole? The gravitational attraction of a black hole is so strong that not even light can escape it. Spaghettification: A black hole would stretch an astronaut’s body into a thin ribbon, since the gravity pulling on their feet is so much stronger than on their head.
