Theory of everything: do we really need one?

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everything? And are we anywhere near achieving one? Featuring Vlatko Vedral, a professor of physics at the University of Oxford and Chanda Prescod-Weinstein, an assistant professor in physics and astronomy and core faculty in women's and gender studies at the University Of New Hampshire. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Is time an illusion?

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Will we ever have a fundamental theory of life and consciousness?

What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, we don’t really know yet. Life seems to just somehow emerge from non-living parts. Featuring Jim Al-Khalili, professor of physics at the University of Surrey and Sara Imari Walker professor of physics at Arizona State University.

Know your place: what happened to class in British politics – trailer

The relationship between class and political preference in Britain used to be clear cut – Labour for the working class, the Conservatives for the middle class. But not any more. In a new five-part series, Know your place: what happened to class in British politics, Laura Hood, senior politics editor at The Conversation, explores what fractured the relationship between class and voting in the UK, and why no politicians can take the working class vote for granted. The first episode launches on October 7. Know your place is a series supported by the National Centre for Social Research. It's produced and mixed by Anouk Millet for The Conversation. The Conversation Documentaries, formerly The Anthill podcast, is home to in-depth audio series from The Conversation, a not-for-profit independent news organisation. Find out more and donate here.

How Iran shut down the internet

On January 8, as thousands of Iranians took to the streets in nationwide protests, the government cut off the internet. Under cover of digital darkness, the Iranian regime launched a brutal and deadly crackdown against anti-government protesters. After three weeks of internet blackout, reports from web traffic monitor Netblocks suggest that the internet is slowly coming back online but predominantly for government-approved users. Yet for most of the shutdown, banks and some local government websites and apps still worked. And that’s because Iran is developing its own, national internet, cut off from the rest of the world. In this episode, we speak to Amin Naeni, a PhD candidate researching digital authoritarianism at Deakin University in Australia, about how Iran built one of the world’s most sophisticated systems of digital control. This episode was written and produced by Mend Mariwany and Gemma Ware with editing help from Katie Flood. Mixing by Michelle Macklem and theme music by Neeta Sarl.

Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, has spiked since the movie Everything Everywhere All At Once was released. The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to stop the destruction of the multiverse. The multiverse idea has long been an inspiration for science fiction writers. But does it have any basis in science? And if so, is it a concept we could ever test experimentally? Featuring Andrew Pontzen, professor of Cosmology at University College London, Katie Mack, Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics, and Sabine Hossenfelder, research fellow of physics at the Frankfurt Institute for Advanced Studies.

How Minneapolis is organising against ICE

Whenever federal immigration agents pull up to a location in Minneapolis, people take their whistles out, start blowing them and start filming. In December, US government sent more than 2,000 Immigration and Customs and Enforcement (ICE) agents into Minnesota in December as part of Operation Metro Surge. The residents of the metropolitan area known as the Twin Cities – Minneapolis and St. Paul – quickly came together to protect and support their neighbours at risk of being caught up in ICE raids. In this episode, we speak to Daniel Cueto-Villalobos, a doctoral candidate at the University of Minnesota, who lives in southern Minneapolis and studies race, religion and social movements. He tracks the neighbourhood groups that have sprung into action in response to the ICE presence back to mutual networks set up during the 2020 Covid pandemic and in the wake of the murder of George Floyd by a Minneapolis policeman. This episode was written and produced by Katie Flood with editing help from Mend Mariwany. The executive producer is Gemma Ware. Mixing by Michelle Macklem and theme music by Neeta Sarl.

Pemerintah cairkan BSU: solusi lesunya daya beli masyarakat?

Pemerintah Indonesia kembali menggulirkan program Bantuan Subsidi Upah (BSU) sebagai bagian dari upaya menjaga daya beli masyarakat pekerja di tengah tekanan ekonomi. Program ini mulai dicairkan pada 5 Juni 2025, menyasar para buruh dan pekerja yang memenuhi syarat tertentu sesuai regulasi ketenagakerjaan dan kebijakan ekonomi nasional. BSU ini dirancang sebagai bentuk intervensi fiskal langsung untuk membantu kelompok pekerja yang terdampak dinamika ekonomi seperti deflasi atau menurunnya daya beli masyarakat. Bantuan ini diberikan sebesar Rp300.000 per bulan selama dua bulan (Juni–Juli) dan langsung dicairkan sekaligus sebesar Rp600.000 pada bulan Juni. Pemerintah mengalokasikan dana sebesar Rp10,72 triliun untuk pelaksanaan program BSU tahun ini. Di tengah tantangan seperti inflasi dan ketidakpastian global, pemerintah berharap bantuan semacam ini bisa menjadi stimulan bagi masyarakat supaya tetap bisa menggerakkan roda ekonomi. Apakah pemberian BSU ini benar benar menjadi solusi jitu untuk menggerakkan perekonomian negara yang belakangan dianggap lesu? Dalam episode SuarAkademia terbaru, kami membahas isu ini bersama Jaya Darmawan, peneliti ekonomi dari Center of Economic and Law Studies (CELIOS). Jaya berpendapat BSU menjadi salah satu instrumen andalan pemerintah untuk merespons tekanan ekonomi yang dialami masyarakat kelas pekerja. Meskipun program BSU bermanfaat dalam jangka pendek, ia menganggap besaran bantuannya belum mampu mengimbangi tekanan ekonomi saat ini. Salah satu masalah yang menurut Jaya juga perlu disoroti adalah kriteria kelayakan penerima manfaat. Banyak pekerja tidak memenuhi syarat bantuan karena batasan administratif yang tidak mempertimbangkan kompleksitas kerja informal. kriteria penerima BSU ini membuat pekerja yang ada di sektor informal kerap luput dari jangkauan bantuan sosial, meskipun mereka berada dalam posisi paling rentan secara ekonomi. Meskipun kebijakan pemerintah ini perlu disambut dengan baik, namun Jaya beranggapan langkah-langkah ini masih belum cukup untuk mendorong daya beli masyarakat secara berkelanjutan. Ia berpendapat perlu ada pergeseran arah kebijakan dari sekadar bantuan jangka pendek menuju strategi jangka panjang yang lebih menyeluruh. Fokus kebijakan pemerintah sebaiknya tidak hanya memperbaiki daya beli secara sementara, tetapi juga membuka akses terhadap pekerjaan yang layak dan mendukung pekerja untuk keluar dari sektor informal. Menurutnya, pemerintah perlu memikirkan strategi yang lebih komprehensif untuk menciptakan kebijakan ekonomi yang tidak hanya responsif terhadap krisis, tetapi juga berorientasi pada transformasi sosial dan ekonomi yang berkelanjutan.

Potensi energi angin di Indonesia begitu besar, mengapa kincirnya harus kecil

ENERGY.GOV/WIKIMEDIA, CC BY-SA Angin punya posisi penting bagi sejarah panjang peradaban manusia. Sekitar 7000 tahun lalu, angin tercatat telah memutar baling-baling kapal di sepanjang Sungai Nil di Mesir. Di Cina, 200 tahun sebelum Masehi, hembusan angin telah memutar kincir sederhana dan membantu petani memompa air. Sejak abad ke-20, angin telah menggerakan turbin dan menghasilkan listrik untuk rumah di Eropa dan Amerika Utara. Selain lebih murah, tenaga angin juga terbukti jauh lebih ramah terhadap lingkungan. Tapi mengapa Indonesia sepertinya sulit melakukan hal yang sama? Apa kita kekurangan angin? Adi Surjosatyo, Guru Besar Departemen Teknik Mesin Universitas Indonesia, mengatakan potensi Indonesia sangat besar. Tapi, menurut dia, selama ini kita telah keliru dalam memandang tenaga angin. Di Eropa, daerah kontinental, turbin angin dibuat besar karena angin besar. Tapi di daerah Indonesia, turbin angin harus kecil karena kondisi udara dan kelembapan air laut membuat angin di Indonesia kecil. Rata-rata kecepatan angin di Indonesia dua kali lebih lemah dari angin di Eropa. Hanya sekitar 2,5 sampai 3 meter per detik. Kecepatan angin rendah, kincirnya pun harus kecil. Itulah yang dilakukan oleh Adi di Kampung Bungin, Muara Gembong, Bekasi. Dia bikin energi terbarukan dari angin untuk mengaliri listrik kampung nelayan tersebut. Satu kincir angin setinggi 11 meter hanya butuh Rp 50 juta. Setelah memasang beberapa kincir di pinggir pantai, biarkan angin yang bekerja sepanjang waktu. Edisi ke-29 Sains Sekitar Kita ini disiapkan oleh Ikhsan Raharjo dan narator Malika. Selamat mendengarkan!
