do we take any action when we send something into space so we don't send any microb or similar put there? or else could there be microbial life out there that started from bacteria that traveled in one of our manned or unmanned machines?

Where is it? I can't find it. So many things are being upscaled, this 1 would be so worth it!! Do you know anyone who is doing it?

Imagine a hidden lab nestled deep within the Himalayas, where scientists have just succeeded in tearing the very fabric of space-time. As the tear widens, a ripple of cosmic energy sweeps across the universe, distorting reality itself. Stars flicker erratically, and entire galaxies seem to shimmer and waver like mirages in the vast expanse of space.

On a cosmic scale, the tear creates a cascading wave of disturbances. Nebulae and star clusters are pulled into a chaotic dance as gravitational forces go haywire. The once-stable orbits of celestial bodies become erratic, causing planetary systems to spiral into unpredictable trajectories. Massive gravitational waves ripple outward, warping the fabric of space-time and creating mesmerizing but destructive cosmic phenomena.

In the affected regions, reality begins to unravel. Space and time become fluid, with temporal anomalies creating paradoxical loops and cosmic distortions. Spacecraft navigating through these zones encounter strange and dangerous phenomena: wormholes that bend time, energy surges that defy physics, and areas where the laws of gravity seem to flip unpredictably.

Humanity watches in awe and trepidation as the cosmic disturbances unfold. Stars are born and die in the blink of an eye, and colossal energy bursts light up the sky with colors never before seen. Scientists and explorers scramble to understand the nature of the tear and its far-reaching consequences, racing against time to find a way to stabilize the cosmic fabric before it’s too late. In this thrilling cosmic drama, the tear in space-time reveals the universe’s hidden complexities and challenges our understanding of reality itself. As the universe adjusts to these unprecedented disturbances, it becomes clear that the boundaries of space and time are far more fragile—and fascinating—than anyone ever imagined.

I've just watched episode 11. Towards the end of the episode a montage of technology shows some rather surprisingly modern (for 1980) technology, and even "Netscape" being used (released in 1994 I believe).Was this inserted later (for the DVD set?), and why?

Thanks in advance.

There’s a few uploads of “Cosmos: A Personal Voyage” on archive.org, one of which has a Public Domain tag on it.

I don’t see the title in a search with the US Copyright Office’s website. I do see that the Tyson era ones are.

I’m not sure how strict archive.org is about reviewing metadata for its accuracy.

I ask because I’m potentially interested in screening it at an institution that abides by copyright.

Thank you!

There was no up,
there was no down,
there was no side to side.

There was no light,
there was no dark,
nor shape of any kind.

There were no stars or planet Mars,
or protons to collide.
There was no up,
there was no down,
there was no side to side.

And furthermore, to underscore this total lacking state,
there was no here,
there was no there,
because there was no space.

And in this endless void, which can’t be thought of as a place,
there was no time,
and so no passing minutes, hours, days.

Of all the paradoxes
that belabor common sense,
I think this one’s the greatest:
this time before events.

Because how did we go from nothing
to infinitely dense?
From immeasurably small
to inconceivably immense?

But before we get unmoored from the question at the start,
let’s take a breath and marvel
at when math becomes an art.

Because we don’t have to understand it
to know there was a time
when there was no up,
there was no down,
there was no side to side. … But wait, my friend,
let’s not pretend
that nothing was the guide.

For in this void,
did something stir,
a force we can’t describe?

A spark of life,
a guiding hand,
to whom we can ascribe

the marvels
of the universe
in all its great design.

So let us now
remind ourselves
there’s more than fits our mind.

Beyond the world
we understand
to challenge our pride.

When up and down
and side to side
will come to meet their end,

I know beyond
the slightest doubt
before Him I will stand.

Does anyone recall an episode of cosmos where Tyson is talking about astrology and astronomy and how the two where once one but then split into separate communities I can't seem to find it there a line I'm looking for he says "astrologist where asked to conduct experiments to prove the legitimacy of their study and the leading experts replied with no why would we when we have had satisfied customers for thousands of years" can someone help me please?

I can’t find much info online

This is some of the overlooked data from HIP-7276 (a main sequence G type star like the sun) I used the transit method, the brightness of the star dips at regular intervals every 30 or so days with some fancy math I found that the (POTENTIAL) exoplanet is 3x the size of earth i really want some insight on this and i hope i dont look stupid.

Hello everyone,

I'm on the hunt for science fiction books that delve into themes of space mining, humanity's expansion and colonization of space, evolutionary robotics, and swarm robotics. If you have any recommendations that explore these fascinating topics, I'd love to hear them!

Your suggestions will be greatly appreciated and I'm excited to dive into new worlds and ideas. Thanks in advance for your help!

But I dream…

"Exploradores del Cosmos: Una Comunidad para los Amantes del Universo"

Hello guys, I want to start a space science channel and i need genuine people who are interested into this stuff, i would request if anyone of you wants to see my videos that would be your great help, I am not saying you to subscribe the channel because that will only happen if you genuinely like my content. if anyone who watch such stuff on YouTube and wants to watch my video let me know. I thought of asking you all , if anyone of you interested , I will DM you my video and would like to know your feedback about the content. reply Only if you are genuinely interested :) No force to anyone.

Hello guys, what do you think about our tiny existence in the entire universe ? like is there any purpose ? wy do we exist in such a huge universe ? is there any goal we should assign to whole humanity ? purpose ? what ? let me know in comments :)

Our astrophile community always gives us an example of universe vastness to support to an argument that our existence doesn't matter at all and we are just a pale blue dot in the vast cosmic universe with almost zero power in this universe. Isn't it that it is because of our small size that our species survived. If we would have been a little bigger, the cosmic forces and events would have influenced us a lot of maybe would have destroyed our planet earth. Isn't it a blessing that our small size is what has kept us hidden and alive in this universe. What's your views on this?

Why does Neil on the first episode : "The last time we were here together this hallway had no name...." I tried googling but there aren't any previous series except the ones made by Carl Sagan. Am i missing something or were there other series/documentary before? Thank you in advance!

From black holes to dark matter, what cosmic enigmas keep you up at night pondering the vastness of the universe? Let's delve into the cosmos together!
