Can humans hibernate their way to Mars?
One of the biggest problems facing humans attempting to travel anywhere in space that’s farther than the moon is the years it will take to get there. A small ship simply can’t support normal human life for that long. We need too much food, water, exercise and stimulation. But … what if we...

Astronomers from the National Radio Astronomy Observatory in West Virginia have spotted two black holes have been 'dining' side-by-side.
Funny how relative things are especially when they say just 750 light years away from each other, meaning even if you had a rocketship going at the speed of light, it would still take you 750 years to get there. That is far as fuck!Virgin Orbit's failed launch EXPLAINED

The key lesson to learn from science's greatest debate
In 1920, astronomers debated the nature of the Universe. The results were meaningless until years later, when the key evidence arrived.

heres a twist for you...that planet 750 light years away...means the light and image youre seeing in your telescope is actually what that planet looked like 750 YEARS AGO.. we're NEVER seeing anything contemporary time. its ALL IN THE PAST! JW telescope picked up a star some 13 billion light years away....(13 billion years ago)...chances are great that star either no longer exists OR looks vastly different now and it will take another 13 billion years before newer images are seen.

Lol wut
humans colonizing another celestial body (planet or moon) will eventually adapt to that environment and future generations will have changed to the point where they cant live in an earth environment and may have evolved in ways that no longer make them human in the same manner we are. They may be HUMANOID having a head and two arms and legs (maybe) but they wont be all the things that we define as human.
3 reasons why astronauts can't walk after landing on earth
Reason #1: Living in a microgravity environment causes bone and muscle loss
Reason #2: The cardiovascular system is also affected by microgravity
Reason #3: Microgravity also causes balance issues
The human body is designed to work in Earth’s gravity, which means that when astronauts return to Earth, their bodies have to readjust to the planet’s gravitational force. Astronauts may experience a reduced sense of balance, mobility, and coordination after landing on earth. It usually takes a few days to a few weeks for astronauts to recover from their time in space and feel back to normal.
However, for some astronauts who have spent extended periods of time in space, it can take months to recover from the effects of microgravity. In the case of Canadian astronaut Chris Hadfield, it took him five months to re-adjust to Earth’s gravity after spending five months on the ISS.

Has Earth’s inner core stopped its strange spin?

This is interesting. From the article "The results could help to shine light on the many mysteries of the deep Earth, including what part the inner core plays in maintaining the planet’s magnetic field and in affecting the speed of the whole planet’s rotation — and thus the length of a day."Has Earth’s inner core stopped its strange spin?
