Kisiko nahi Pata sahi se In theory, massive explosion from a single point leading to expansion of universe. But light only produced after 300k years of Big Bang(Because of cooling down, leading to combination of electrons and Protons to first product atoms) So impossible to say because no one can 'see' before that. But thats a noob answer, more knowledgeable people may answer better.

BacktoCricaddict Posted July 23, 2022 Posted July 23, 2022 (edited) WADR to the brilliant people who do this work, space research is just not exciting to me. It is too abstract. Being a utilitarian, I lack the vision to perceive any benefits to anyone/anything within the next, say, 200 years. I get excited by things that are more tangible; things that help provide a better quality of life for all humans now: more-food-on-less-land, zero hunger, and prevention and cures for various diseases/afflictions. But the pictures are stunning. Edited July 23, 2022 by BacktoCricaddict Vickydev 1
Lone Wolf Posted July 23, 2022 Posted July 23, 2022 I suppose instead of looking at space have we even try to scorch the corners of our Oceans?? I suppose a huuuuuuuuuuge portion is yet left unexplored. Countless other species are yet to be identified. Who knows what's down there in those depths? I expect few costly submarine missions have been launched but technology & focus atm is just not quite there.

It doesn't relate at gormint level. ISRO & DRDO have their own budgets & objectives and a shitload of bureaucracy between them. In any case, the thread was about space in general. Are the snake charmers not allowed to discuss Webb telescope or astronomy ? coffee_rules and ravishingravi 1 1

My tiny brain can't make sense of it tbh Max is 46 billion light years so that's 46 billions years back. So some form of early precambrian looking lifeform around 3 billion lightyears away will give a low probability of sentient lifeform now. Edited July 24, 2022 by Vilander

Chale hain space... Why are you blaming the space arm or its objectives here ? You ought to understand that ISRO & DRDO are not competing with one another. Both have their own importance, and to be honest one works primarily on defense tech while the other does a multitude more than that. ISRO's commercial arm actually makes money for the country. https://economictimes.indiatimes.com/news/science/isro-earns-279-million-in-forex-through-satellite-launches/articleshow/93159973.cms Now if DRDO can't build an engine or tech transfers were affected by sanctions or netas/babus where too busy prioritizing something else, its not ISRO's fault. Only the jahil padosi leaders like this clown are critical of ISRO projects, surely you don't belong to their level of intellect. coffee_rules 1

Vickydev Posted September 29, 2022 Posted September 29, 2022 1 hour ago, Mariyam said: Could you please further elucidate on the part in bold. It's about how these images captured are of objects that are 13 billion light years away, so light travelled that many years to reach the telescope. That's the age of the universe. Here this would explain it better: https://imagine.gsfc.nasa.gov/features/cosmic/farthest_info.html#:~:text=We know that light takes,appeared 13 billion years ago. To add to the second point, it's actually now 46 billion light years away as @Vilanderexplained above in one of the posts, because of the Universe expanding. https://www.forbes.com/sites/startswithabang/2020/01/25/ask-ethan-how-can-we-see-46-1-billion-light-years-away-in-a-13-8-billion-year-old-universe/ Mariyam 1

The furtherest we see the furtherest we see into the past of the observable universe. the way you bolded that but tells me you are on to something , can you ‘elucidate’ that ? Mariyam 1
