New photos shared by SpaceX show that the company has nearly finished installing a total of 39 upgraded Raptor engines on a new Starship and its Super Heavy booster.

Those prototypes – known as Ship 24 and Booster 7 – could be tasked with supporting Starship’s first orbital launch attempt sometime later this year if both make it through upcoming test campaigns without major issues. Whether that’s a probable outcome is still uncertain but recent progress suggests that it won’t take long for the prospects of both prototypes to shift into clearer focus.

After several rounds of proof testing and two trips to and from SpaceX’s Starbase, Texas orbital launch site (OLS) in March, April, and May, Super Heavy Booster 7 (B7) made its third trip to the pad on June 23rd.

The typical office worker often has soreness throughout their body as a result of their sedentary desk jobs. Even young individuals may develop shoulder pain, which was previously primarily an issue for elderly people. Once shoulder pain creeps in, it is difficult to dress oneself, let alone move one’s body freely. It is also difficult to fall asleep. While the rotator cuffs are often naturally harmed as we age, repairing them has shown to be difficult.

So many of hopes and dreams for colonizing space rely on faster than light travel, and yet the ability to move between stars in moment seems against the laws of reality… but perhaps we can break those rules.

Our capability to render virtual realities better and better makes it seem likely one day we could simulate our world flawlessly, and perhaps our minds too. If so, perhaps we will in the future… and perhaps we already did in the past.

In Episode 3 we look at the concept of warp drives, a theoretical type of spaceship propulsion that warps spacetime to allow faster than light travel. We discuss the basic concept and the scientific and technological hurdles to developing it, along with clearing up many of the myths about it.

Black Holes are amongst the most destructive things in the Universe, but it may be that properly utilized, they might be the best places in the galaxy to live around in the future, and possibly right here in our own solar system too.

The Fermi Paradox contemplates the weirdness of our galaxy seemingly being devoid of intelligent alien life, but Many Worlds Theory, Multiverses, Parallel Universe, and Alternate Realities may radically alter our thinking on Aliens & SETI.

Here’s an intriguing idea. What if you were informed that everything in your life was pre-planned? Even crazier, what if your history, present, and future are all taking place right now?

An incredible new theory established as the “block universe” theory asserts that time does not actually “flow like a river”; rather, everything is ever-present.

Dr. Bradford Skow, a philosophy professor at the Massachusetts Institute of Technology, proposes that if we “look down” on the cosmos as if it were a piece of paper, we would see time stretched out in all directions, just as we perceive space at any given time.
