Why is everyone so focused on Mars?

Everyone knows that energy that goes in to a black hole is trapped forever. Slipping past the event horizon, falling infinitely into an infinitely empty, infinitely deep and yet still infinitely dense well, concentrated in an infinitely small pebble at the bottom. We all know this energy is trapped forever... or is it?

Technically, the universe expanded from an explosion which is called The Big Bang. As space quickly expanded, the universe cooled and matter was formed. One second after the Big Bang, according to scientists, the universe was filled with tons of neutrons, protons, electrons, anti-electrons, photons and neutrinos.

Space crafts were built to explore in space and discover the unknown. The first reusable spacecraft by NASA was launched in 1981.

The bigger they are, the larger a zone of “no return” they have, where anything entering their territory is irrevocably lost to the black hole. This point of no return is called the event horizon.

The space shuttle faced a problem when landing, it was orbiting Earth at over 17,000 mph with almost no air resistance or engine power to help slow it down.

The billionaire space race that has been taking place for about 20 years has finally hit mainstream media as new innovations and promises take the world by storm.

The ongoing Russia-Ukraine war is bad, but there is a way that other countries can help. That is satellites, whether for communication or imagery, and they are saving lives and helping Ukraine every day.

There has always been a question about whether or not aliens exist, or if there is any sort of life on another planet. Well, scientists have discovered evidence that shows signs of liquid water on Mars,...

The four seasons are caused by the axial tilt of the earth, also called obliquity, but what if the axial tilt of the earth changed?
