How can we learn about the universe?

Radio astronomers use radio telescopes to study the radio frequencies given off by objects and processes in the universe. Ultraviolet, x-ray, gamma-ray, and infrared astronomy reveals the cosmos in other wavelengths of light. Astrometry is the science of measuring distances in space between objects.

What exactly is a universe?

The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons.

Milky Way
The term “Milky Way”, a term which emerged in Classical Antiquity to describe the band of light in the night sky, has since gone on to become the name for our galaxy. Like many others in the known Universe, the Milky Way is a barred, spiral galaxy that is part of the Local Group – a collection of 54 galaxies.

Why do stars explode kids?

But the nuclear fuel burning in the star’s core creates strong outward pressure. The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode! Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula.

How do you think the universe began?

Just a few ideas about how it began White holes. You may be familiar with black holes. Big bang theory. One origin could explain, in simple terms, the beginning of the universe. Theory of slow freeze. So, what if the Big bang wasn’t the actual beginning, but just a part of the process? Mirage of the black hole. Plasma creation. No beginning/ no end. Pulsating universe.

How big is the universe?

The observable universe is about 46 billion light years in radius. Scientific observation of the Universe has led to inferences of its earlier stages. These observations suggest that the Universe has been governed by the same physical laws and constants throughout most of its extent and history.
