How the Universe Will End

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 beyond this point, the universe would rip in half.

Big Freeze

In this theory, the universe will infinitely expand. During this time stars would have burned out either turning into white dwarfs, neutron stars, and black holes. After trillions of years, the white dwarfs slowly become black dwarfs(the true end of a star), neutron stars will soon die because they need some type of source in order to produce heat to still maintain itself. After this occurs, black holes start to die off. Black holes die-off in a process called Hawking Radiation. In Hawking Radiation, a minute amount of mass gets radiated away from the black hole.

Big Bounce

In this theory, the universe will meet its fate through the Big Crunch theory. But after this occurs, a Big Bang is produced. This would mean that after this universe dies, and the new universe is born, and this would continue for an indefinite amount of time

The universe will die. It would die whether it being one of these theories or not. This is why people should focus on space exploration since people would be able to preserve life in the universe.

    Hey ram this is spandan,

    Question for you. I am really into all of this but I am just curious, where did you get all of this info for your website from?

Chemistry of the Rocket Fuel

      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 types of fuels suc

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
