How the Universe Will End

Image
The Universe is currently expanding at around 150,000 miles per hour(240,000 kilometers per hour). At some point in time, the universe will end maybe due to this. Scientists have 4 theories about how the universe will end. The four theories are Big Crunch, Big Freeze, Big Rip, Big Bounce. Big Crunch How the Big Crunch Theory works As the name suggests, in this theory the universe will collapse on its self.  In the universe, there is a theoretical object called "Dark Energy". This is what is making the universe expand at such a rapid rate. In the Big Crunch theory, the gravitational attraction of the objects within the universe will overcome Dark Energy and the universe will start decreasing in size until it reaches the point where the universe will collapse. Big Rip In this theory, the universe would reach the point where it has reached the maximum expansion. This is the distance where the universe has fully expanded. If the universe continues to expand beyon...

Space Travel

Space travel is very important in the future. It will allow the human race to survive in the future when the time comes when Earth is no longer useful to human beings. Space travel would allow humans to colonize more land and even communicate with other lifeforms that may live in this galaxy. In space travel, you must have some type of fuel that will allow you to reach very high speeds(i.e 50% speed of light). So for this, you might want to use the energy produced by nuclear fusion. Nuclear fusion is when atoms collide into each other under very high pressure. This would create enough fuel for you to reach very high speeds. Although you have the fuel you need to go at high speeds, you can also use the planets. The gas giants have an immense gravitational pull and you can exploit this by maneuvering your rocket around, for example, Jupiter. This will allow you to gain more speed after you exit the gravitational pull of Jupiter. This technique has been used by previous satellites(i.e ...

Space Conditions

Image
Space has always been a mystery. It is hard to know what goes on space due to our limited reach, but one thing that astronomers know is the conditions of space. Ever since the Big Bang, space has been changing, from size to the contents within space. The conditions of space show what it was like near the beginning of time. As time progresses, space will continue to shift and change. Space is a vacuum. There is little to no particles(excluding things like stars, galaxies, planets, etc.) in outer space, so this means that there is no friction at all in space. Because of space being a vacuum, the temperature in interstellar space(a place in space where it has no effect from nearby stars and other astronomical bodies) is around 3 °  K(K means Kelvin). To put it in perspective, that is about -270 ° C or  -454 °  F.  But when there is something like a star or planet near, the temperature around it is much higher. For example, the temperature around the Earth is around...

Chemistry of the Rocket Fuel

Image
      Rockets are one of the ways that help explore space. Rockets allow people to launch satellites, and some of those satellites are engineered to help explore space. Without rockets, it would be very hard to understand space since the satellites that are out in space produce much more accurate and precise information. For example, the Kepler Space Telescope(a satellite that explores planets in different places around the galaxy) was able to gain lots of data on exoplanets. The observatories on Earth are not able to use such accuracy as Kepler Space Telescope. Without rockets, satellites like these can not be launched into space. This post will be about how the physics and chemistry of rockets(this will be oversimplified because rocket science is a very complicated topic).  First, let's start off with the chemistry of rockets. There are different types of rockets, but for now, we will be talking about liquid fuel rockets. In rockets, there are many different typ...

First Space Blog

First Space Blog Hi there viewer,  I want to ask you some questions. I want to know what are your views of the universe. Here are some questions that might help you to answer the question above: What is the universe? This philosophical question talks about your vision of the universe. Is it beautiful? Is it wonderful? Is it horrible? What does it mean to you? Questions like these are helpful for me to understand what others think about it. It helps me realize how others take the vision of the universe into their own hands.  Another question I want to know is that do you think there is life somewhere else in the universe. This question talks about whether or not there is life anywhere else. These questions may help you to answer the question: Is it possible? Could there be life? Is it possible to find life on Mars or on Titan (largest moon of Saturn and has a very thick atmosphere)? Is there life maybe in the solar system? Could it be possible to find life on an exopla...
