UNIVERSAL
In times of misinformation and science denial I decided to use my tools to help spreading scientific knowledge and perhaps make more people curious about these topics.
"UNIVERSAL" is a self-initiated project exploring concepts of physics and science.
“The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.” - Carl Sagan
Gravity - Einstein`s general theory of relativity explains gravity as a distortion of spacetime caused by the presence of matter or energy.
Black hole - A region of spacetime where gravity is so strong that nothing - no particles or even electromagnetic radiation such as light - can escape from it.
Singularity - In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.
Expansion of the Universe - Galaxies are receding away from us with a velocity that is proportional to their distance from us: more distant galaxies recede faster than nearby galaxies.
Andromeda - Andromeda is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way. It’s also the most distant thing visible to your unaided eye.
Gravitational Lens - A gravitational lens can occur when a huge amount of matter, like a cluster of galaxies, creates a gravitational field that distorts and magnifies the light from distant galaxies that are behind it but in the same line of sight. The effect is like looking through a giant magnifying glass.
Gravity bending light - Spacetime gets bent due to large masses, which also affects light trajectory.
Multiverse - The multiverse theory is a group of models assuming that our physical reality encompasses more than one universe.
Redshift - When light travels through space its wavelength gets stretched due to the universe expansion. This causes a shift to the red part of the spectrum.
Spacetime - Spacetime is a conceptual model combining three dimensions of space with the fourth dimension of time.
Wormhole - A speculative structure linking disparate points in spacetime.
