Space Travel

The short explanation is that the Universe is expanding, not static. Light from a clump of matter that left 13.8 billion years ago, and started heading towards (what is now) us, has been traveling for 13.8 billion years. Therefore, you would think that that light has traveled 13.8 billion light…

That depends, the fastest currently in existence or the fastest we can build right now? The fastest currently in operation would be the Voyager 1 space probe, at nearly 17 km/s, which would take roughly 75.000 years to arrive at Proxima B. More interesting in my opinion is the fastest…

When gazing at the night sky, the sheer vastness and enormity of our universe begins to set in. Truly nothing comes close to this unconquered boundlessness, worthy of being dubbed as our “final frontier” yet human ingenuity is persisting to change this. Although a lot of goals that will be…

Let’s clear some assumptions first. Black holes do not ‘swallow’ anything. Black holes behave just like any other gravitating body meaning, objects fall due to the gravitational pull. See it this way Earth’s acceleration due to gravity is 9.8 meters per second² and so when you drop an object into…

Mercury is the first and closest planet to the sun and its gravitational pull in our solar system. Due to such high gravity mercury can’t hold on to it’s moon. If mercury have a moon, it may crash into mercury’s surface or be pulled by the sun into it. The…

Venus is probably as close as you can get to what has been described as Hell. It may be roughly the same size and mass as the Earth, (and named for the Goddess of Love), but forget about visiting. The temperature on Venus exceeds 850 degrees F. (Existing NASA spacesuits…

Reasons to colonize Mars instead of the Moon: Less rocket fuel needed to land. Has an atmosphere which can be used to produce Oxygen and rocket fuel to return home. Has much more ice in the soil over much more of the surface. Lower levels of cosmic and solar radiation. …
