Can we go to future?
Believe it or not, time travel is possible. In fact, you’re doing it right now. Every single second of every single day, you are advancing into your own future. You are literally moving through time, the same way you would move through space.
What are time machines?
A time machine is a device which brings about closed timelike curves—and thus enables time travel—where none would have existed otherwise.
What are the 3 main galaxies?
Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars.
What is included in the universe?
It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist. The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty.
What are the 4 types of galaxy?
In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies.
How many galaxies are irregular?
Four irregular galaxies, as observed by the Hubble Space Telescope. Hubble recognized these two types of irregular galaxies, Irr I and Irr II.
Can a human go through a wormhole?
Physicists have worked out a way that it might be feasible to send someone through a wormhole. Wormholes are tunnels between two black holes that connect distant regions of space-time, and normally it would be impossible to pass something through them, but factoring in an extra dimension might make it possible.
Why do we need to go back to the past?
It’s important to honor our past and pass it on. Looking back on the past allows us to study the nature of ourselves and helps us recognize why we do what we do. It’s important not look too much into the past or keep your mind there for too long – you can easily get trapped there.
Can we travel to future?
While the debate continues over whether travelling into the past is possible, physicists have determined that travelling to the future most certainly is. And you don’t need a wormhole or a DeLorean to do it. Real-life time travel occurs through time dilation, a property of Einstein’s special relativity.
What shape is an irregular galaxy?
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
