Would we ever be able to build a Time Machine?

Image
Well, Time Travel is just a  technical problem  now There are several ways we can travel in time (future), two of them are, 1. Orbiting a Black Hole -  Time slows down as we reach an object with high gravitational potential. So, we could orbit closer to a Black Hole, then for us time will run slower compared to the people on Earth. 2. High Velocity -  As per relativity, the faster we move slower the time gets. So, if we could build a spaceship that can reach speed closer to light, then we would be able to travel in time. As I said, right now time travel is a technical problem & our today's technology isn't advanced enough to build such spacecraft. However, some people are trying make this happen, for example,  Harold White  at NASA is trying to build an  Alcubierre Warp Drive .

Does Aliens exist in our Galaxy...How can we connect with them ?

Image
Believe,  Yes, they do!  Here's why, As per the latest estimation, our Milky Way Galaxy contains between 200-400 Billion stars & there exist at least 100 billion potentially habitable Alien planets.

Are aliens real ?

Image
I think so aliens are real but there are 6 types of species found on our planet. One of them is animals and us but the other five are not yet known. We don't have that capability to see them. If you ever happen to read QURAN the Holy Book of Muslims, you could find that Allah has made Prophet (SAWW) Superior over all universes and all types of species. This hits a clue to our brains that aliens may be real. Our eye is blocked to see the other 5 types of species found on our own planet. I think so one of them includes ghosts also but who knows. We could only be able to find it after we are dead. - These are all my personal views only.

What lies behind a Black Hole ?

Image
Black Holes sucks nearly everything that comes in their path, but where does that matter go? Some scientists believe that Black Holes ends up as a White Hole. Once you enter a Black Holes you will come out from the other end in some other universes or far somewhere far away. But it's just a theoretical idea, no scientific proofs.

Questions that science couldn't answer yet!! Can you ?

Image
Here's a list of questions that science couldn't answer yet.  credit: TedEd Why do we dream? How did life begin? Are we alone in the universe? What makes us human? What is consciousness? Is the multiverse theory correct? What is dark matter & what are its properties? What is the purpose of human existence? How the Universe will end? How many species exist on earth? What lies beyond the Universe? How gravity works? What existed before the Big Bang? How does a bicycle stay upright? How & Why do we move forwards in time? Why does space have only three dimensions? Can we get energy from nothing? Is the universe really infinite or just very big? How does the brain generate consciousness? Can we replace damaged brain parts with computational devices? What happens when you die? What are the cures for the world's biggest health problems, like cancer and dementia? Can humans reverse or stop aging? Is there a limit to how smart humans can be? Is biology as universal as chemis...

What would happen if Apophis Astriod hits Earth's surface ?

Image
Apophis was discovered by  Roy A. Tucker ,  David J. Tholen  &  Fabrizio Bernardi  on June 19, 2004. It is a 400 meters wide & 26.99 billion kg heavy asteroid with an average orbital speed of 30.728 km/s. Astronomers calculated that there's a small possibility of Apophis hitting Earth in 2029 or 2036. So, what will happen if Apophis hits the Earth? On hitting Earth it will produce an Energy of more than  100 thousand Hiroshima bombs , which is enough to destroy an entire country. In case it lands in highly populated areas or countries like India, China, or America then it will kill millions of people within a few minutes of destruction. Now you might be wondering how do we stop this Asteroid from hitting Earth? Well, today we don't have any good practical solution to stop an asteroid that big. But, here are a few ideas that might be helpful in the future. Laser Beam -  By pointing a strong laser beam on the asteroid we can actually change...

What was the beginning of Universe?

Image
In the beginning, the Universe was nothing but a  Singularity.  A singularity is a point of infinite mass  & density. Singularity seems stable as we study it today, but in the early universe because of  quantum fluctuations , it wasn't stable at all. That instability resulted in a huge explosion we call  Big Bang. From our current understandings of Big Bang, Time or even Space didn't exist before the Big Bang, everything started altogether with this explosion. In the beginning, the Universe was like a very hot  soup  of pure energy having all the ingredients required for the formation of atoms. Within a few microseconds after Big Bang particles like quarks, leptons, gluons, Higgs, etc came into existence. But since the universe was expanding & cooling at a fast rate, these particles started to coalesce & formed other fundamental particles like electrons, protons & neutrons. But Universe was still expanding & cooling down, so the ...

Is it possible to travel in Time ?

Image
Yes, it is!  Scientists have been trying to find out new ways to travel in time for decades. Earlier it seems impossible, but not anymore. According to scientists,  Time Travel  is now just a  technical problem  that we need to solve. Here are a few possible ways to travel  forward in time , Orbiting a Black Hole -  As per Theory of Relativity we know, time slows down as we get closer to an object with high gravitational potential. Black Holes are the objects with intense gravitational potential, so if we could go closer to a Black Hole in a space-ship & orbit around it, then for us time will run slowly as compared to the people on Earth. But the problem with this idea is that Black Hole's gravity is so intense that it bends the space-time fabric & if our spaceship will try to approach a Black Hole it will probably never return. High Speed -  The faster you move, the slower the clock gets. Albert Einstein explained it as  Time ...
