Sound barrier was broken a long time ago. Ever since that law was broken, sci-fi geeks have been waiting to see more of “fantasy come true”. One of which is the warp drive from star trek. How far are we from that? Or how close are we? Let me not drag the answer, scientists believe that it is quite impossible considering Einstein’s Theory of Relativity. Nothing can travel faster than the speed of light – however, if we could compact and expand the fabric of space-time ahead of and behind us, technically we could travel faster than the speed of light. Technically. Anyway, like i mentioned earlier It’s just…

Remember, the important thing is not to stop questioning – Albert Einstein
I dedicate one week of every month’s to post about questions taken from Quora. Here goes this month’s bunch. Where exactly is our solar system located? If you examine our Milky Way graphical upper view, it sort of looks like an octopus’s top view but with spiral shaped arms. These arms illuminate interstellar dust and gas. Each arm, named as Perseus Arm, Sagittarius Arm, Centaurus Arm and Cygnus Arm and our solar system lies in the Orion Spur which is a minor arm. It is located 26,000 light years from the center of the Milky Way Galaxy. Here is NASA’s pictorial view: What happens if the Sun turns into a…

New discoveries – yet again! 72 new galaxies found.
Astronomers at the ESO (European Southern Observatory) have found 72 new galaxies hiding in the plain sight. This was observed by Multi Unit Spectroscopic Explorer (MUSE), a second generation instrument in development for the Very Large Telescope (VLT) of the ESO. The galaxies were observed on the area in space called “Hubble Ultra Deep Field”, usually where many telescopes are pointed in search for such galaxies. But what makes MUSE different is that, it uses spectroscopy to break light into its component colors. And as it happens, these galaxies emits Lyman-alpha light which is a particular wavelength of ultraviolet light – which MUSE was able to detect unlike other telescope…

Answers ready to be served! – Astronomy Q&A for the month.
As mentioned in my last month’s post, I am dedicating a week to answer questions picked from Quora about Astronomy. So here is this month’s batch. What would happen if a bullet was shot in outer space? Answer: Space does not have oxygen but that doesn’t mean your gun won’t fire. Modern gun has ammunition that has its own oxidizer that triggers the explosion. So when you shoot a gun into space two things happen: Experience Newton’s third law of motion, you being on the other side and with higher mass, you will move backwards. The bullet keeps going into the space towards infinity as universe expands faster than a…

Elon Musk’s plan on sending people to Mars.
Elon Musk – the man who can bring a SciFi fantasy come true, atleast that’s how I would like to picture him (I know many would agree with me); the CEO and the co-founder of SpaceX. He has great visions about the future one of which is colonizing Mars by 2024 with two ships reaching by 2022 filled with cargo and he plans to do it effective and safe. He recently provided an update to his 2016 presentation regarding his long term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. In his recent speaking at the International Astronautical…

Astronomy Q&A
So I was wondering what to different for my blog and it hit me. This one. I am going to pick 5 astronomy related questions from Quora and answer them! Serious ones and sometimes funny ones. (Maybe in the future I will take questions from the public and answer five out of them.) And it doesn’t end there. Q&A is going to happen twice in a month. One week about Astronomy and one week about Life Advices/Interesting Facts. So this week’s picked up questions: What would happen to your naked arm in the vacuum of outer space? Answer: Arms or any part of the body, you are going…
